What adhesive should I use to install PureBond formaldehyde free redoak 1/4" plywood to osb?

adhesive Q# 2534 / Submitted 11/21/2013

You do not indicate the end use, but if you are looking to glue pieces of our product to OSB, any of the typical wood glues sold at your local home center should work fine. Hope this helps!



When specifying HPVA HP-1 hardwood veneer plywood premium grade what submittal requirements should be accepted. What is the thickness of Sepele Mahogany veneer on 3/4" thick panels. What is standard detail for veneer edges?

HPVA HP-1 Plywood Veneer Panels Q# 2532 / Submitted 11/15/2013

The veneer thickness will vary after the panel is pressed and sanded, but typically sapele veneer will range from .200" to as thin as .015" before being assembled into a panel. Overall panel thickness for a 3/4" panel can range from .703" to .750". As far as the edge detail is concerned, we provide a raw edge that will require further treatment by the fabricator if the edges are to be exposed. Options for treatment may include, but are by no means restricted to wood veneer tape, solid wood, plastic banding, or even steel, aluminum, or brass. Thank you for your inquiry!



Please have someone call me on my mobile 502-693-9958. We are doing a curved wall on a house that we would like to use two layers of the 3/8" bendable, glued, and nailed 6" o/c. There will be a air gap of 1 1/2" then stone will cover it up. Thank you Lee Bruner K-I Lumber Company

38 bending plywood Q# 2528 / Submitted 10/5/2013

Lee, I apologize for the lengthy delay in my response, especially considering I would feel quite uneasy using this product for an exterior application. The adhesive used is a very moisture resistant proprietary forumlation, but it is not water proof, and is not intended for use where it may be exposed to anything other than casual contact with moisture. I am sorry I couldn't have been more helpful.



I want to design a queen size murphy bed, which will have a plywood base under the mattress. I would like this to be one continuous piece both for structural reasons and so that there will be no seam visible when the bed is stored against the wall. Are special order sheets available in 5' widths or larger? I might consider some sort of veneer or panelling on the outside if I do have to put two sheets together. Do you offer or can you suggest a product that would give a seamless appearance to the outside?<br />Also, I saw that your website states that purebond is not available in NM. The Home Depot website says it has standard 3/4 and 1/4" sheets in stock in Albuquerque. Does this mean that special order is now available there too? Thanks for your advice.

large sheets Q# 2526 / Submitted 9/26/2013

Unfortunately, we do not currently offer 5' wide panels in our special order program, and as yet are not serving The Home Depot in the New Mexico market. I am sorry I couldn't help you in this particular situation.



Columbia, I am trying to build some projects and reduce the amount of formaldehyde etc in my home. I purchased product# 165948 from Home Depot since it was the purebond brand. I didn't realize it was a MDF type of core as opposed to solid wood. I'd like to know is the MDF core( or whatever the core is) also made from formaldehyde free components? I notice it says CARB I compliant on the little sticker and I'd assume if it was formaldehyde free then it would have qualified for being CARB II compliant. Any details you can provide on the formaldehyde or other chemical contents of this product would be very much appreciated. Thanks Derek

question about plywood core Q# 2525 / Submitted 9/25/2013

If the product in question was marked CARB II compliant, that would mean the entire panel, not just the core was produced with formaldehyde free adhesive, or one so low in formaldehyde emissions as to be considered insignificant with respect to indoor air quality. There would be no additional chemical compounds that would would be expected to off-gas under normal living conditions. I hope this helps!



type of screw used in pull out test for classic core? Screw type, thread pitch, length, size, etc.

type of screw used in pull out test for classic core thread pitc Q# 2521 / Submitted 9/17/2013

There are a number of variations in screw withdrawal from wood testing today, but typically a #8 or #10 wood screw is used. There are certain tests that prescribe specific fasteners, but lacking the actual test report from the several years ago these tests were performed, I can't be certain exactly how the tests were performed. We do not typically produce panels for structural performance as our products are considered decorative in nature as oppossed to structural. With new product launches we do occasionally submit specimens for testing and we will publish the average values in a spce sheet. I wish I could be of more assistance.



I am from the Art Conservation Department of the University of Delaware and am trying to find the optimum building material for museum display cases. Steel, aluminum and glass won't work for everything in the museum world. Wood construction is ideal for the specialty display case for that hard to fit object. From research I have done on your PureBond plywood with the soy flour/PAE adhesive made by Ashland and others, I feel this would be a good fit. But I am baffled by the trade name of your products and whether the core adhesives can sometimes by different from the top laminate. And then there is UV Wood which describes the finish coat but not the core. I realize wood products have their own off-gassing components. But if we can eliminate the adhesive source of contamination we will be making progress. If you could give me the product designations and descriptions that will lead me to the "greenest" materials, it would be very helpful. Sincerely, Chris Petersen wcptrsn@aol.com

Low VOC products Q# 2519 / Submitted 8/28/2013

Chris, we make so many combinations of products utilizing a wide variety of core materials, including engineered core produced by others, that it can be confusing when listed on a MSDS. To set your mind at ease, the adhesive we use is free from any volatile organic compounds, including formaldehyde. While we can certainly produce a panel utilizing an MDF or particleboard core that is formaldehyde, probably for your particular application, specifying a VENEER CORE PureBond panel will ensure that ALL adhesive used in the entire panel will be our formaldehyde free soy based adhesive, and thus the panel will be formaldehyde free with the understanding, as you have acknowledged, that wood itself does contain various extraneous compounds, most of which would not be expected to ever volatilize at ambient temperature for a museum setting. I hope this helps!<br /><br />Ang



Hello, I've read that all PureBond plywood is made from sustainably harvested wood, and that it can be FSC certified on request. Does this mean that all PureBond plywood is manufactured according to FSC standards but sometimes isn't labeled that way? Or does it mean that it is manufactured in some other sustainable manner, but can be manufactured according to FSC standards? Sorry for the wordy question! I'm just building furniture for my house and want to go with the most eco-friendly option I can find, and Home Depot didn't know the answer to my question. Thanks! Joel

FSC certified Q# 2518 / Submitted 8/21/2013

Joel, every now and again I get a question that I just don't feel as qualified to answer as perhaps I should be, and this happens to be one. I am sure I could give you something reasonable and accurate, just not as complete as I would like. So...to answer your question, I have turned to our Certified Wood expert, the most knowledgeable person I know on the subject, our own Paul Davis. I have cut and pasted his response below:

Hi Joel-

Thanks for your question.
Presently, about 15% of Columbia's panel production is sold as FSC Certified through retail and wholesale distribution channels combined.
We get more FSC certified logs than that though and roughly as much as 25% of the panels Columbia makes today could be sold if conditions were "ideal."

The balance (other 75% of wood fiber used) is either Controlled by FSC definitions or is sourced as composite board (like particleboard and medium density fiberboard) which Columbia also uses in addition veneer cores.
Columbia has rolled out FSC SKUs in selected Home Depot Stores across the United States and Canada.
You can tell if a product was sold as FSC by looking at the edge printing which should include a "RA-COC-000065" reference which is the Columbia chain of custody license number.

But coverage is not absolute across all species offered



My question was not answered properly.While I am happy that your product is voc free I would still like to know if any of the elements of your soy based glue produces fumes or vapors, as this is being used in a room with someone with health issues!

re: plywood questions Q# 2517 / Submitted 8/20/2013

I am sorry I did not properly address your concerns. As you know, a VOC is any compound that volatalizes (breaks down into a free gas) at normal ambient room temperature. This includes formaldehydes and other acetaldehydes that have historically been a health concern in pressed wood products. Our PureBondTM formula does not contain formaldehyde in any form, nor does it contain any compound that would be expected to fume or off gas under normal use, and therefore it should be considered suitable for anyone with health issues. For clarification, conditions outside normal use generally means when the product burns, some compounds naturally present in wood (not added in production) will volatilize, but barring a calamity such as a fire, there are no compounds in our glue that will off-gas. I hope this clarifies my answer. I am always pleased when anyone asks follow-up questions if they feel they did not get the answer they were looking for initially. Thank you.

Ang Schramm



I have justed purchased a 3/4 birch formaldehyde free plywood piece to try on top of my sub flooring. I was wondering if this product off gasses at all any type of vapors from your soy based glue?? As I have major sensitivities to chemicals and vapors and such.I was planning on using this on top of my pre existing reg plywood subfloor so like I said my concern is replacing all of it with your product to find out it may give off some kind of vapors. Any information would be greatly appreciated as your product build quality seems above the rest.Im hoping the air quality is vapor free 100%.

Formaldehyde free hw birch questions Q# 2516 / Submitted 8/19/2013

There are no volatile organic compounds (VOCs) in our PureBondTM Panels. Thank you for your concerns and for your question.



I saw your product at Home Depot when I was looking for A-C plywood. I likefd the finish but could not be sure if it was rated for exterior use.

Exterior use Q# 2515 / Submitted 8/6/2013

Our panel products are intended for use in indoor applications such as kitchen cabinets or furniture. It is not suitable for exterior service. Thank you for your interest in Columbia Forest Products panels. <br /><br />Ang

Hello! I am trying to find a good supplier for materials in making my art for my business. I need a high quality, strong and lightweight plywood for printing on. An example of what I am trying to do can be seen at this website: www.printsonwood.com I am not sure what type of plywood they use, but I was hoping you could lead me in to the right direction as to what kind I should use. The edges of the cuts have to be flawless and the surface light and smooth as well. I would like the 1.25" thickness. What are the options you have for something like this? And do you have places in Minnesota to purchase this material? Thank you for your help! Leah

More information on different types of plywood- Q# 2512 / Submitted 7/12/2013

There are folks doing exactly what you are trying to accomplish using what is termed white maple (more accurately, sap maple) faces on a medium density fiber core. I would recommend staying with something along those lines, and probably in a 3/4" thickness. The 1 1/2" thickness is not only extremely heavy, it is also more of an oddity for your local big box retailer or lumber yard. Even the 3/4" weighs around 100 pounds for a 4X8 sheet. The product cuts and machines well, and the surface grain of the maple face is tight and smooth. You should be able to find it at one of the big box folks, and most of them have the ability to cut the panels into more manageable sizes. I hope this helps.<br /><br />Ang



Jeff<br /><br />I have a customer who wets maple veneer to raise the grain before finishing and he is having a problem with the veneeer wrinkling and bubbling. I am pretty sure that our Purebond plywood, it is acceptable to wet the veneer without having issues. Do you think there is a process problem or a plywood problem?<br />thanks<br />Wally Quinn<br />Atlantic Plywood<br />781-254-0347

veneer wrinkling Q# 2511 / Submitted 7/11/2013

Wally, it could be both. Wetting the face can certainly cause a stress reaction that could result in a bond failure, depending on the amount of water introduced. However, for a Type II plywood bond, brief exposure to light misting should not ordinarily create the type of bubbling and wrinkling, which are indicative of bond failure between the face and adjacent substrate as reported here. Without actually being able to see the process or resulting failure, I cannot draw any conclusions, but I suspect the surface bond may have been weak, and the water added process generated enough stress to cause that already weak bond to fail. This type failure is often quite alarming, but it is almost always an isolated occurence as the adhesive system is formulated to meet Type II bond requirements set forth in the ANSI/HPVA HP-1 Standard, and our independent and internal testing indicates that such failures are actually quite rare. I hope this helps!<br /><br />Ang



Hi I want to use the 3/4" oak plywood for a bar top. It will have an 8" overhang. Will one sheet be sturdy or will I need to stack two 3/4" sheets for a total of 1.5 inches? please let me know.

bar top Q# 2508 / Submitted 6/11/2013

I can't recommend any particular construction as it is ultimately up to the end user to determine suitability for their particular application. Having said that,I will give you some things to consider. For home bars, most I have personally observed are constructed with a 3/4" thickness built out to 1.5" on the outer edges to give the impression of full 1.5" thickness. For commercial use, most are made using specialty face thickness panels as the face on standard production is typically very thin, usually under 1/36". Thicker faces are available, but very difficult to obtain except through special order, and then usually with minimum quantities. As far as built up thickness, I have seen both double thickness panels and built up edges, so that choice would be yours. Hope I've helped. Thanks so much for your question.<br /><br />Ang



Dear Ang:<br /><br />I purchased your product SMARTWOOD PBOARD sku# 406227 a long time ago. It may be before PureBond panel existed in the market. Can you please confirm that this perticular product is a PureBond panel? Do you or did you sell/sold and plywoord that is not a PureBond panel? Thank you very much. Donna Zhang

Follow up with Q#2505 Q# 2506 / Submitted 6/6/2013

I can't positively confirm it, Donna, but we have been producing PureBond panels since 2005. If your panels were purchased after that time they likely are PureBond. If they were purchased after 2007, all older material would have been out of the supply chain by then, and I would be confident in saying they are. Without knowing exactly when and through what outlet they were purchased, that is about all I would feel comfortable saying. I hope this helps.



Hi I purchased your product SMARTWOOD PBOARD sku# 406227. Please let me know if this plywood is safe to use in the bedroom, if it contains any toxic chemical such as formaldehyde because this will be used in an infant bedroom. Thank you very much Donna Zhang

Safety of your plywood product Q# 2505 / Submitted 6/6/2013

Our PureBond panels are produced using a natural soy based adhesive system which does not contain or emit formaldehyde. It would certainly be acceptable for infant furniture. Thanks for your interest in our panel products!<br /><br />Ang



Dear Columbia Forest Products, Is your formaldehyde free plywood and/or particle board suitable for use as a subflooring material? For example could it be used in mobile/manufactured homes in place of conventional particle board flooring? Also what chemicals are in the glue? For example is there phenol in it? Thank you, Nita

Plywood and particle board questions Q# 2504 / Submitted 6/5/2013

The no added formaldehyde particle board core panels we provide may be manufactured with either an MDI adhesive or phenolic, neither of which are considered to be of any health risk. We apply faces and backs to these cores using a non-emitting soy based adhesive system. However, as for your question regarding application, while conceivably you might use them for flooring, they are manufactured with a very thin face that would make them unsuited and not recommended for that particular application. Thank you for your interest in our PureBond formaldehyde free panel products.<br /><br />Ang



I'm interested in using PureBond plywood...not exactly for exterior use, but inside a greenhouse that I'm converted to a studio. So there may be some moisture that comes into the greenhouse, though mostly it will be dry. Using it for wall panels. Will PureBond plywood work in these circumstances? Is there a particular kind of wood that would be best? Thanks so much for your help.

exterior use Q# 2502 / Submitted 5/14/2013

Our PureBond panels are manufactured with a water resistant adhesive that must meet testing requirements for Type II (water resistant) plywood in accordance with the HPVA HP-1-2009 Industry Standard for Hardwood and Decorative Plywood, making it generally suitable for most interior applications. Ultimately, it is up to the end user to determine the suitability of a panel product to meet their specific needs and I generally refrain from recommending one for any specific application. However, based on your description of the end use, I would certainly not be comfortable with our Type II panels in that application. You may want to consider specifying a panel made with Type I or water proof glue. Thank you for your question.<br /><br />Ang



Hi, Can you explain what the plywood 'core' is made up of? For some reason I am getting confused and am thinking there is a MDF component or layer within the plywood panel...is the PureBond the only adhesive used in a plywood panel? Thank you, Hillary

What is it made of Q# 2500 / Submitted 4/27/2013

It is understandably confusing, Hillary. The term plywood in the context of decorative panels basically means any component or combination of components that make up the core, or that part of the panel that is not seen, as compared to the very thin face and back wood veneers that make up the aesthetic element of the panel. The inner components may be particleboard (PBC), medium density fiber board (MDF), or thicker cut veneers of more innocuous and readily available species of logs like poplar and fir, or there may be a combination of these. At any rate, when we glue all the components as multiple plies of inner core with a decorative face and back in a construction most users call plywood core all in our own mills under our control, we use our proprietary PureBond adhesive system. We do not manufacture PBC or MDF, but we do purchase them from manufactures who use alternative adhesives that are now available with no urea formaldehyde or no added urea formaldehyde, and we do use them in our PureBond panels ordered with these core types. I hope this is helpful. Thanks for a great question!<br /> <br />Ang<br />



Recently we have been having trouble with finishing hardwood veneer core plywood. Cherry especially so but also now seeing the same type of horizontal striations repeated across the width of a normal sheet in walnut and ash veneer core. We purchase plywood from several companies including Atlantic Plywood, Kerns, Goodfellows, and others. All my salesmen are telling me that they cannot guarantee that we will not see this problem. At first I thought it was a sanding issue, that the veneer core was not getting a second sanding and started inquiring about that. we were told that we needed to switch to MDF core for our veneer sheet goods . We still see the problem and it does not show up till finish goes on. the Issue I believe is the supper thin top veneer is allowing the glue spreader pattern to bleed through. This is not acceptable for high-end furniture that we build. Can you recommend a product and distributor that has a true furniture grade veneer core product in Cherry, Ash, Walnut, Mahogany and other hardwood species? <br /><br />Thank you,<br />

veneer is too thin Q# 2496 / Submitted 4/3/2013

I apologize for the lengthy delay in responding to your question. <br /><br />Today's decorative faces are indeed super thin. Most are in the range of 1/46" or thinner (0.021"). Veneer core, as you know, consists of multiple plies of readily available, generally non decorative species such as yellow poplar, aspen, white fir, or pine, cut much thicker relatively speaking than the face and back. Because wood is a naturally hygroscopic material, it freely allows water in molecular form to move into and out of its cellular structure. As this happens, the wood will change dimensionally, and may even fracture along its weakest point, generally parallel to the lathe checks that develop inherently during the actual veneer peeling process. These fractures may or may not be visible early on, but as time goes by they may, and usually do become visible. Because of this tendency, exacerbated by the thinness of decorative faces available today, an engineered substrate such as particleboard or medium density fiber board may be more suitable alternatives to veneer core. Should veneer core be more desirable for some reason for a given application, consideration should be given to specification of a combination core such as Columbia Forest Products' Classic Core. This construction is essentially a veneer core panel except that next to the face and back are thin plies of MDF rather than veneer. The remaining inner plies are still veneer. This construction combines the best of both substrates to allow a veneer core look while eliminating exposure to the potential telegraphing of the unavoidable lathe checks through the panel surface. <br /><br />Regarding the possiblilty of glue spreader roll pattern transfer, this is certainly a potential issue as well. If you are still experiencing the problem with engineered substrates, it would be advantageous to capture samples showing examples where the lines are present in the finished panel and have those sent to the providing mill for further evaluation. There are rigid processes in place in any hardwood plywood manufacturing facility to ensure that optimum glue spreads, stand times, and pre-press times are utilized to ensure the function of the bond without compromising the appearance of the panel. The mill should be able to determine if there was a hiccup in the process.<br /><br />I hope this helps.<br /><br />Ang <br />



how well does it hold up under damp or high moisture content, and low temp<br />

columbia pure bond Q# 2495 / Submitted 3/13/2013

Our PureBond panels are intended for end use in indoor applications. Optimum conditions to ensure acceptible performance include maintaining temperature between 65 and 75 degrees F, and relative humidity between 40 and 60%. Continuous exposure to conditions outside these ranges could spell trouble. Thank you for your question!<br /><br />Ang



I am looking for SIP building materials for a new cottage which needs to be low or no emissions, due to chemical sensitivities. We want to use SIPs but don't find them with other than OSB, some with v-matched pine, but I want a simpler solution in kitchen where I will be hanging cabinets.<br />thank you

purebond SIPs Q# 2494 / Submitted 2/25/2013

We do not supply panels for Structural Insulated Panel Systems, but we do for kitchen cabinet manufacturers. To my understanding, SIPs are used for the exterior structure of a residential or commercial building. The system consists of an outer shell of OSB or structural plywood, with varying thicknesses of styrofoam insulating panels glued between. The inner side of an outside wall would need to be covered in some decorative material, either wall paneling or dry wall, and your cabinets would then be attached to the decorative wall. The OSB or structural plywood panels are manufactured with a phenolic adhesive system which emits extremely low levels of formaldehyde. I am sorry I could not be more helpful.<br /><br />Ang



I'd like to use your 5/8 oak panel model PB58OAKC216FSC to cover a finished basement ceiling. The local building code requires that the average flames spread rating be less than 150 for that application. I've reviewed your Flame Spread Performance of Wood Products document, but don't see a description that matches that oak panelling. What is the average flames spread rating of your 5/8 oak panel.

Oak Panel Average Flames Spread Rating Q# 2493 / Submitted 2/13/2013

The Design for Code Acceptance published by the National Forest and Paper Association contains figures for a variety of wood products and species under the section "Flame Spread Performance of Wood Products." All the hardwood plywood items tested for this publication produced flame spread results between 76 and 200, which is the level published for Class C as set forth by the National Fire Protection Agency, NFPA-101. Similar products have been tested by Columbia Forest Products, all of which also meet the requirements for Class C. This statement applies to all our products. Due to the costs associated with testing, and the infrequency of requests for such rating, we rely on the testing data referenced herein. We have, as indicated, tested a variety of products, but by no means have we tested them all.<br /><br />The rating system is based on a rating of 100 for red oak flooring.<br /><br />Smoke developed in all tests is 450 or less.<br /><br />To view the entire AF & PA document, follow the link: http://www.awc.org/Publications/dca/dca1/DCA1.pdf. <br /><br />Unfortunately, I cannot guarantee that the panels in question would meet the 150 level, but they do meet or fall below the 200 level. I hope this helps.<br /><br />Ang



I'm making a pair of sliding closet doors for my bedroom. I've seen lots of plans for MDF molding-reinforced 1/4" plywood. But I'm wondering if I can just use two simple sheets of 1/4 or 1/2 inch ply for a modern feel. Our house sees extremes in humidity over the course of the year, and I'd be concerned about warping without the MDF reinforcement. Any thoughts? Thanks! Rand

bedroom closet door Q# 2492 / Submitted 2/9/2013

I wish I could be of more help, but due to the nature of wood to move, even engineered wood, warp will always be a concern in the environment you describe. I would suggest looking at similar applications that have proven to work in your area and attempt to replicate those designs. Even then, there is no guarantee against wood movement.<br /><br />Ang

Actually, I'd like to use a material that paints up well, light weight, 1/4" - 1/2", and can be glued to solid poplar frame...suggestions?

glue panel to frame Q# 2488 / Submitted 12/6/2012

Any decorative panel product can be glued to a solid wood frame of any species. The question is "should it be?" It is well documented that due to the hygroscopic nature of wood, that is its tendency to freely take on or give off moisture, wood will expand and contract with changes in relative humidity. For that reason it is not recommended that components be glued without some means of compensation for movement. I have seen wood glued together perform satisfactorily, but I don't recommend it.



poplar frame...1/2" panels...your plywood. Glue the panels in or use spaceballs?

Space balls! Always better to allow for expansion and contraction to be expected with wood products in service. Thanks for a great question!<br /><br />Ang



I am pricing a project and the City requires a flame spread rating of the veneer, yet they spec it to be applied to 3/4" fire rated substrate. could you provide me with a rating or explanation to satisfy the city. they require a minimum of .09mm for veneer thickness. thank you for your help.

flame spraed rating Q# 2485 / Submitted 11/7/2012

Please follow this link to an informational article on fire rating for wood products: http://archive.constantcontact.com/fs058/1102117931485/archive/1102890314836.html. For most wood products, the flame spread rating is Class C (76-200) with a smoke developed of 450 or less. When a fire retardant core is used, the flame spread is Class A (0-25) with a smoke developed of 450 or less. Historically, veneer thickness of 1 mm (1/28") or less does not affect the flame spread rating of a panel with a fire retardant treated core. Thanks for your question!<br /><br />Ang



Thanks for your detailed and thoughtful response to my question. Have since learned that over-length slats not to have veneer. Had also come to same conclusion as your recommendation - that other oak veneers will not provide same character as EBO. Have some follow up questions though:<br />1. Can you recommend a supplier for the face veneer?<br />2. Do you have opinion as to allowance for wastage?<br />3. We are concerned that client has only seen small pieces actual veneer. Not sure of overall look when scaled up to larger panels. Do you have any images you could share of larger panels done with EBO?<br /><br />Many thanks,<br /><br />Brian

Question 2483 Q# 2484 / Submitted 10/30/2012

Thanks for your feedback! As to your questions, calculating waste can vary depending on species, and with English Brown Oak being one of those distressed species that may require a bit more processing, you may not experience more than about a one to three conversion of raw veneer footage to panel goods. In other words, a flitch of EBO may indicate 1500 square feet of veneer availability, leading a specifier to believe it will cover 1500 square feet of millwork, or 45 4X8 plywood panels. In fact, the yield of useable veneer may actually be no more than one-third of that for a total of only 500 feet, or only about 15 4X8 panels. This is why with a species so expensive as this, there must be so very much communication between all parties in the process to ensure that the needs and expectations are clearly understood by the specifier, the end user, the veneer producing mill, the panel producing mill, the fabricator/millworker, and everyone else in the process. For this reason, small pieces are absolutely not acceptable as they can actually be misleading. Live flitch samples representing enough veneer to provide the final calculated square footage required are the only acceptable form of samples, and if the footage is high enough to warrant, a trip to the producing mill by representatives of all parties can and indeed should be arranged. <br /><br />The only image of EBO we can readily provide may be found on our website under Resources: Veneer Species Guide: Oak, English Brown. I have copied a link to that page on our site, http://columbiaforestproducts.com/VeneerGuide, for your convenience.<br /><br />As far recommending a supplier, there are a number of very good ones out there, many of whom are current suppliers to Columbia Forest Products. Because of these relationships, I am reticent to recommend only one or two, but you may wish to contact the Hardwood Plywood and Veneer Association, 703-435-2900, or hpva.org, for a copy of their Where To Buy publication that lists veneer members and their specialties and contact information. I would check with more than one to establish your own comfort level. <br /><br />Again, thanks so much for your interest and comments!<br /><br />Ang



am working with a client in Calgary, AB, Canada which is very dry climate....semi-arid. Project is for 8000 sq.ft. home with all millwork, paneling, cabinetry, etc to be finished with English brown oak. I would appreciate your advice and experience based input on the following and any other issues you may be aware of.<br /><br /> Cabinetry will be flush panel doors planned for MDF construction with solid wood or plywood frame. Veneer applied across entire surface.<br /> Some of the doors will be close to 8' tall. There will also be manufactured 2" X 6" slats (close to 14' tall) finished with veneer to be hung in a louvre fashion.<br /> We would like to have all work done in Nanjing, China by very experienced high quality firm there that has done extensive work with veneer. They would prefer to use a natural oak veneer available from local supplier there with stain to match E. B. Oak. But client is (right now) insisting on English product for look of graining, texture of its surface, and natural appearance. <br /> Our Chinese firm has excellent facilities for kiln drying materials.<br /> What is your opinion of having veneer shipped from your location to Nanjing for manufacture there and shipping by container back to Calgary which has average humidity of 55% in the winter(but much lower inside homes due to forced air heating) and 45% in the summer. Nanjing has<br /> mean relative humidity of 74.8% and which ranges from 70% to 80%.<br /> We have the luxury of time to permit us to ship the finished product and maybe even veneer by container ship to reduce costs.<br /> Do you have any customers who may have similar experiences?<br /> How durable is e.b. oak vs others?<br /><br />As I said, any and all information and advice you can provide would be greatly appreciated.<br /><br />Regards,<br /><br /> Brian Thomas, Calgary

English Brown Oak Q# 2483 / Submitted 10/25/2012

Your question presents a number of concerns, the greatest of which is the possibility of substituting "natural" oak and having it stained to match English Brown oak. English brown oak is actually one of the white oak members of the genus, quercus. The brown discoloration and distressing results from fungi that form colonies throughout the tree due to damage to the crown, sometimes artificially induced, sometimes as a result of a natural injury. It has a deep, lustrous color and quality that makes it difficult to match with ordinary, or natural white oak for all but the most economical of settings. Given the time and the amount of shipping and fabrication, this job appears to be a highly critical architectural project and it would not be advisable to use anything other than the material already specified. A second concern is that I do not detect any indication that the specs call for any approval of flitch samples of the English brown oak. Given the nature of that material and the natural variation inherent in any character marked wood product, sample approval and retention by all parties to this project would be strongly advised. Another concern is your question regarding our providing the veneer. While we are one of North America's largest supplier of hardwood and decorative softwood face veneers and hardwood plywood, English brown oak is not among the species we manufacture for face veneers. While we have experience manufacturing panels with English brown oak faces, we would procure those faces from a third party, which would be my recommendation to you. As far as the durability of English brown oak to other species of red or white oak, the differences are not so great as to make a measurable difference on a veneered product, given the thickness of the face relative to the overall thickness. <br /><br />This question is one that, to me, opens the door for many, many more questions that must be asked and answered before the order is put in motion to ensure that all parties are protected at every turn and that, most importantly, the end user is satisfied. When the specs include 2" X 6" slats, 8' doors, 14' lengths (whether end matched or continuous run), all going into an 8000 square foot house, produced on 2 continents and traversing the Pacific Ocean not once, but twice, I strongly recommend that every step in the process, as well as every aspect of the wood and expectations for the finished appearance, be reduced to writing and all parties sign off on same. <br /><br />I apologize for the long answer, and I am certain you have probably considered most, if not all my recommendations, but one can never be too safe! Thanks so much for a great question!<br /><br />Ang

I just retired and started woodworking and want to build an entertainment center, kitchen hutch, bookcases and the like. With all the various products, grades, and core types I am lost as to what would be a good general plywood product to use for these projects. Any recommendations? Thank you

Plywood product recommendation Q# 2476 / Submitted 4/12/2012

Congratulations on achieving this milestone and for your choice of diversions to utilize your time!<br /><br />As you are discovering, there are a bewildering number of considerations for panel products for home projects, including species, grades, cuts, matches, core options, and the like. My recommendation, as with any new endeavor, is to start with the simple. The Home Depot offers veneer core panels in a couple of thicknesses in red oak and birch. The grade for the decorative surfaces of these panels is "C" for the face and "3" for the back. This means the face is a mid-range grade with a generally very pleasing appearance which does include some naturally occuring characteristics including small knots and possibly mineral streaks or discoloration that should not distract from the overall appearance. These panels make an excellent choice for any project, including the ones you indicate. They are easy to saw, shape, edge band, sand, and finish to just about any stain and topcoat you can choose. Because they are produced with a veneer core, sometimes called a "plywood core," the edges will show the different layers constituting the core, so most folks choose to cover this with an edge banding of veneer tape or solid lumber that may subsequently be profiled in your choice of styles. <br /><br />You may also find a dealer in building supplies in your area with a few more options in species and core, so this may also be an option for you. Other core choices may include medium density fiberboard (MDF) or particleboard (PBC). These also machine well and offer a very smooth sanding surface. They are generally 25% or more heavier than veneer core, but the thickness tolerances and surface quality are somewhat better than veneer core, though they are not quite as strong from a physical properties consideration. <br /><br />If your mind is set on choices not available off the shelf at Home Depot or a local dealer, you may want to consider an option to go to The Home Depot Pro Desk and special order your panels. There you may choose from a wide variety of core, species, and grade options for the number of panels you need. To learn more, please visit our website, ColumbiaForestProducts.com. Chose "Locate - Retail Distributors - The Home Depot." There you will find our special order process along with a pdf file you may print off to take with you to the Pro Desk at THD to ensure you get what you want. This process takes a little time, but if it meets your needs, it is a very good choice.<br /><br />I hope this helps. Thanks so much for your interest in Columbia Forest Products' PureBond Hardwood Plywood Panel Products!<br /><br />Ang<br /><br />



What state does the red oak veneer come from, or is it canadian?

Red Oak Q# 2473 / Submitted 3/19/2012

Most of our domestic face veneers, including red oak (Quercus spp.) come from managed forests located across a wide range from the upper mid-western states including Michigan and Wisconsin, to name a couple, to the New England region all the way up to Maine, and down into the Allegheny regions of Pennsylvania and West Virginia. Additionally, some of our oak, maple, cherry, and birch does come from Canadian resources located in a generally narrow band region along the US and Canadian border. Thanks so much for your question.

I'm a furniture maker and will be making caskets for local Jewish congregation, using your 1/2" birch ply; question came up...does your adhesive contain any animal by-products? <br />Thanks!

Purebond adh & animal product Q# 2470 / Submitted 1/16/2012

None at all. In the very early days of plywood manufacture, animal blood and other proteins were indeed used, but that practice ended back in the 1960s. Current adhesives are plant based with chemical additives that you would find in milk cartons for the wet strength component. Thank you so much for your question.<br /><br />Ang



Does Purebond itself have any Rapidly Renewable Content? If so, what is the percentage by weight?

Purebond Q# 2469 / Submitted 1/10/2012

The only component in our panel is the soybean flour utilized in the adhesive, but this is a small amount, averaging from 5% to 10% depending on the actual construction. Given that the majority of a plywood panel is wood from trees that generally have a seedling to harvest size cycle exceeding 10 years, that portion is not considererd rapidly renewable. Having said that, wood is one of the few major building components that is renewable at any level. Thanks for your question.<br /><br />Ang



Looking to build a tempory floor with tong and groove 3/4 maple plywood any dangers

Maple plywood Q# 2466 / Submitted 10/1/2011

I would not advise using decorative plywood of any species for flooring. The engineered flooring on the market today is an exceptional product, and while it is manufactured in much the same way as hardwood plywood, it has a very thick outer skin of maple, oak, hickory, or whatever species is chosen. Hardwood plywood, on the other hand, has a very thin skin perfectly suited for cabinetry, furniture, casework, and so forth, but too much risk for use on a traffic surface. If by "temporary" you mean it will be in place for a very short time and early wear and tear is not an issue, I see no reason why not. But, if you intend for it to be anything of a showcase for any period of time I would advise against it. Thank you so much for considering our plywood.<br /><br />Ang

What is the difference between FSC Pure and FSC Mixed Credit.

FSC "Mixed Credit" Q# 2461 / Submitted 5/24/2011

FSC Labels<br /><br />I apologize for the delayed response. As I am not as up to speed as perhaps I should be relative to certification, I deferred your question to our resident FSC pro, Paul Davis. Here is his response:<br /><br />"There are several different types of labels for FSC certified products. Each label is backed by a different set of procedures that certified manufacturers must follow. <br />The two FSC labels most often used in the decorative hardwood plywood industry are the "FSC Pure" label and the "FSC Mixed Sources" label. <br /><br />FSC Mixed Sources <br />As the name implies, the FSC Mixed Sources label is used on products that contain a mixture of FSC-certified and non-certified material and/or recycled material. <br />The FSC requires that the non-certified material portion be from "controlled" sources.<br />This means Controlled Wood must be from sources which are not illegally logged, from high conservation value (old growth) forests, from permanent forest conversions or are genetically modified (GMO.) <br />Inclusion of controlled wood in the FSC Mixed Sources claims allows converters to process FSC volume much more cost effectively, typically as part of an FSC Mixed (credit) handling approach.<br /><br />FSC Pure<br />FSC Pure assemblies contain only wood from forests which are FSC certified.<br />It is a more stringent claim but more costly to implement complete, separate batching of all FSC-Pure products in the panel assembly.<br />The invoice valuation for the purposes of LEED is 100% of the value of the invoice as it is in fact 100% wood from FSC forests.<br /><br />Comparison of FSC Mixed Sources and FSC Pure<br />By comparison, FSC Mixed Credit panels contain wood from FSC-certified forests, controlled wood or a combination of both.<br />The invoice valuation for purposes of LEED is also 100% of the value of the invoice."<br />



Can you give me a formula for making gluesize using white glue and water?

gluesize Q# 2460 / Submitted 3/25/2011

Glue "sizing" usually involves watering down a glue compound and usuing it as a surface binder to lock down loose fiber, seal excessively porous areas, and provide a more uniform surface for final finish performance. There have been a few commercial glue size formulations available, but for the most part glue sizing involves mixing glue, such as the white (or yellow) polyvinyl acetate adhesives with water. I have done this successfully with a little experimentation. I usually start with a 50-50 mix of distilled water and glue, try a little on a scrap piece, allow it to completely dry, then sand the surface thoroughly. This will determine if additional thinning is necessary, and depending on the species you are trying to finish, it could be as much as 80-20 water to glue. Best of luck with your projects!<br /><br />Ang



I am using 3/4" birch Europly PLUS to build toys in which both face and back are exposed. I thought I had made it very clear that both sides must be continuously rotary cut so there would be no visible seams in the veneer. What I got was one side with seams, one side without. How should I specify so I get both sides without seams? Also, where can I find a complete description of how to specify furniture grade hardwood plywood? Thanks!<br />Andy

Is a A1 plywood as stabil for kitchen cab doors as europly?

stability Q# 2457 / Submitted 1/27/2011

The terminology "A-1" indicates the grade of the face (in this case, "A") and the grade of the back (in this case, "1") and thus has no bearing on the physical properties of a given panel construction. Europly is a high ply count panel with a decorative edge that is by its design perfectly suited for doors or drawer fronts in certain applications. As are most decorative face and back combinations, it is available with an "A" grade face and a "1" grade back (A-1). Europly panels are, as you infer, generally stable in controlled ambient conditions (65-75 degrees F at 30-60% RH). In all liklihood, you are looking for a comparison between traditional veneer core panel products, which, when manufactured with a balanced construction and same species face and back, is also a very stable panel under similar conditions. Generally speaking, though, the edges of traditional veneer core decorative panels must be treated in some manner that does not reveal the edges. Hope this helps!<br /><br />Ang



What is the differance between plain sliced red oak ply.<br />and wheat faced plain sliced red oak ply?

Plywood Q# 2454 / Submitted 1/3/2011

As you already know, red oak (Quercus Rubra) is the species, Mark, regardless of how it is processed into functional form. Typically, it varies in color from a soft vanilla color, to a creamy red, to a light khaki (more commonly called wheat or straw color), to a pinkish red, to a dark brown or brownish red. The term plain sliced means the veneer was sliced from the log to create more of an appearance of sawn lumber, and the term "wheat" just means the faces were selected for a light wheat/straw color for some level of consistency within and between shipments. Hope this helps! Thanks for a great question!<br /><br />Ang



I would like formaldehyde-free plywood for substrate for a kitchen counter top. Where can I find this product? Also do you have any prefinished edges that would make my DYI kitchen countertop project less intimidating? What stain would you recommend that would be safe to use on a kitchen countertop wood edge?

Plywood Q# 2452 / Submitted 11/3/2010

Columbia Forest Products' PureBond® formaldehyde free panel products are intended for interior decorative applications. How you design the countertop would have a great deal of bearing on whether our panels would perform suitably for that application, with the most critical consideration being to prevent water from contacting any surface. There are panel products manufactured for such applications that consist of durable softwood components bonded with water proof phenolic formaldehyde adhesives that emit so little formaldehyde that they do not appear on the radar of any of the recent CARB and federal standards that would probably be more suitable for your particular use. Our PureBond® veneer core panels would add beauty with no formaldehyde off-gassing to your kitchen cabinets and would certainly complement your countertops. As far as edge treatments, your best bet is to consult your professional at your local paint supply center. They should be able to recommend a suitable product for your application. Thank you for your interest in our PureBond® formaldehyde free products, and we certainly encourage you to specify them when you order your cabinets! Believe me, you will breathe easier! <br /><br />Ang<br />



Looking for borated treated plywood in smooth finish in verious thicknesses, do you have this?<br />Richard Schuler.

Borated treated plywood Q# 2449 / Submitted 10/19/2010

Borate treatments are typically used to treat framing lumber and construction grade plywood to guard against insect infestation and to act as a preservative. Our panel products are interior grade decorative panel products typically used for interior applications such as kitchen cabinets, furniture, wall panel systems, and the like, and as such are not usually exposed to the same elements. Such finished products in service in a controlled, dry environment with routine pest control measures would not be expected to require such treatment, which could impact their finishability and possibily their serviceability, as they could be considered unsafe at high concentrations to sensitized people, young children, pets, and indoor plants.

I am in the process of setting up a software for cnc machining of hardwood ply parts. I use your PureBond, my distributor is distributor service in Pittsburgh, PA. I need to know what your finish thickness is? Or what do most shops do. It it hard to get a accurate thickness with a mic.<br />Thank You,<br />Al Bentley

Plywood thickness Q# 2442 / Submitted 9/24/2010

Thanks for a great question, Al!<br /><br />There will always be a thickness range in any panel product, regardless of composition, just because of the inherent variation in wood and the manufacturing process. If you are using a veneer core panel, which sounds like you are, the thickness range permitted by the product standard will be plus zero, minus 3/64" (+0, -.047") for panels thicker than 1/4". Depending on construction, that range will be reduced significantly. Your best bet is to contact your distributor and have them get more specific information from the actual mill that produces your panels. They should be able to get you the much more accurate information you need to set up your machining program.<br /><br />Ang



We are trying to find plywood that will pass a boil test for KCMA surver use cabinets. can you help us. i have been seaching for WPB plywood and i cant seem to find it anywere. <br /><br />thank you<br /><br /> Ryan Lovealady

WBP hardwood plywood Q# 2440 / Submitted 9/20/2010

WBP is a term defined in a British standard. It means something like Weather/Boil Proof, and refers to the glue performance. If there is a requirement for a water proof adhesive, you may want to verify that with the KCMA. Product Standard HPVA HP-1-2004 is the standard to which domestic producers manufacture. Water proof glue performance is covered in Sections 3.11 and 4.2, as well as Tables 8,9, and 11. The adhesives most commonly used by domestic producers typically meet performance requirements for Type II, or water resistant, in accordance with the HPVA HP-1-2004 standard. Typically, this performance level is perfectly suited for most cabinetry. Should you require a Type I performance rating, Columbia Forest Products routinely manufactures this through special order. Hope this helps!<br /><br />Ang

I work for a door distributor in Sacramento California and have a project that the architect chose to use VG Fir veneers for. I have been working with wood for 16 years and know the characteristics of most veneers, including Fir. The doors, when they arrive, are the more yellow/light orange color as they have not yet been exposed to any natural light. On the pallet, the extreme edges of the doors tend to darken quickly, resulting in a 1/4" wide stripe up the face of the door on each side of the veneer. If a 4' door is under a 3' door on the pallet then that 12" of exposed Fir will darken to the more reddish Fir color, causing a band of that darker color on that door. <br /><br />Now, I know that over time that the entire door is going to eventually blend together into one color. My problem is that the end user, Sutter Medical, sees these color differences now and is demanding new doors. I have sent literature from the vendor and am actually going to the site today to talk to them. I have told them that some veneers such as Cherry, Fir and Walnut will darken when exposed to UV light but that eventually, the entire door will darken evenly. They refuse to believe me or my vendor, thinking we are just trying to get out of replacing the doors. I was just curious if you have some literature regarding the darkening f these types of veneers in UV light that also states that over time the whole door will darken and it will even out. <br /><br />Funny, when the architect makes a mistake and we don't catch it we get blamed because we are supposed to be "The Experts", however, when "The Expert" tries to tell them that their doors will be fine, they don't believe us....<br /><br />Thanks, <br /><br />Tyson Hartle

VG Fir Veneer Q# 2436 / Submitted 9/7/2010

Tyson, these things can be very frustrating at times and I know it does seem we are sometimes cast as victims of our expertise in a no-win way. You are right in your statement that sunlight, primarily that portion in the ultra violet range, is responsible for the color change as a result of chemical response triggered in the xylem (wood cellulose). You are also right in that over time the color change that took place on the prematurely exposed surfaces will also take place over the remainder of the door skins, thus equalizing in color over time, to an extent. My experience, however, is that this process is time consuming, and generally outside the patience range of most customers, architects, specifiers, and end users, and often the newly exposed regions never quite catch up with the darkening that is still taking place, albeit at a snails pace, in the earlier exposed regions. <br /><br />The real trick, I have learned over time, is to prevent exposure to direct sunlight by designing packaging to cover all exposed wood surfaces, not just those of the particularly sensitive species you mention, so that there are no exposed areas. This can be accomplished with cut to size/shape cardboard, kraft paper, or even black polyethelyne between differing component sizes. This is probably the best way to ensure you don't become embroiled in a situation from which there really isn't a pleasant ending. <br /><br />I don't have anything in my files that would be useful in discussing this with your customer, but one rich resource I have used through the years is the US Department of Agriculture Forest Product Laboratory in Madison WI. Here is their contact info: http://www.fpl.fs.fed.us/contact/index.php<br /><br />I would give them a call at the general number and ask for someone who might specialize in effects of UV radiation from sunlight on raw decorative wood surfaces. If there isn't a specific person with this expertise, and there might be, then ask for someone specializing in general discoloration from outside sources.<br /><br />Best of luck with your research. Hope this helps a little.<br /><br />Ang



I am thinking about building a hutch and I saw this plywood at home depot that is suppose to be a hardwood and wondered how it finishes. I like the bare wood finish but wonder how it does with staining and varnishing...

Sandeply plywood Q# 2435 / Submitted 8/28/2010

Sande (Brosimum spp.) is a species found from Costa Rica to Pacific Ecuador, often used as faces as well as inner plies for stock utility plywood panels. The color is generallly a yellowish to whitish yellow, with a relatively porous surface, and a grain pattern that may vary from relatively straight and unfigured to gnarly and figured. The surface can and often does contain reaction wood, leaving it with a tendency to pop even after sanding, creating a fuzzy appearance. <br /><br />Sande may be used for any type of utility application, but ultimately you will need to make the final determination as to suitability for your particular project. It takes finish material well, but can soak up excess finish in those fuzzy areas, creating a dark, coarse appearance. It is a good idea to test the surface for finish using several scrap pieces before attempting to finish the end product. You may want to consider using a glue sizing or wash coat to tame the fibers prior to staining. <br /><br />Best of luck with your project!<br /><br />Ang

Hi, <br />I am trying to install a formaldahyde free subflooring over a sealed and dehumidified crawlspace. Would your recommend your birch plywood that is sold at home depot?

Subflooring Q# 2430 / Submitted 8/7/2010

We do not warrant our decorative panels as suitable for subflooring or underlayment. However, most underlayment is produced with a phenolic formaldehyde adhesive that is so very efficient at binding formaldehyde at the molecular level that off-gassing is all but eliminated. In fact, such panels are not covered by any current standard because their levels are considered de minimus, or so low as to not be of any health concern. I hope this helps. I am sorry we couldn't help you with an application for our PureBond formaldehyde free panels this time, but sincerely appreciate your thinking of Columbia Forest Products! Please keep us in mind for future decorative panel needs!<br /><br />Ang



whats the difference between poplar plywood and kaycore plywood?

plywood Q# 2427 / Submitted 7/22/2010

KayCore plywood is a veneer core trade named product manufactured by Columbia Forest Products utilizing our PureBond formaldehyde free gluing technology and any of the veneer species available to us at the given mill where it is produced. The core plies selected for placement in the plywood core adjacent to the face and back meet the requirements for grade "K" as set forth in the ANSI/HPVA HP-1-2004 Product Standard for Hardwood and Decorative Plywood. This provides a very smooth surface with only very small imperfections allowed under the thin decorative face. The entire panel is produced to thickness tolerances well within the range of thickness permitted by the above referenced standard. <br /><br />Poplar, whether you mean Yellow or Tulip Poplar (Liriodendron tulipifera), or Aspen (Populus spp.), which is sometimes called Poplar or Popple, is the common name to one of a number of various species of trees typically harvested and processed into core stock. These species are typically found in mills east of the Mississippi River. Our western facility may also use white fir, pine, spruce, or hemlock as inner plies.<br /><br />So, to answer your question as succinctly as possible, poplar plywood is plywood made with poplar core. Kaycore plywood is plywood made with any species, including poplar, fir, pine, hemlock, spruce, or others I haven't mentioned, that is produced to a particular standard.<br /><br />Hope this helps!<br /><br />Ang

Recomended Glue and Joinery for UV Finish Plywoods. Q# 2424 / Submitted 7/21/2010

Dave, your best bet with a glue joint is one that joins raw wood to raw wood, leaving you a couple of choices. One is to rough up the finished area so as to allow at least some bite surface for your glue, which can be tricky with a UV finished panel product. Another is to use a joint that would by its design expose raw wood to raw wood such as 45 degree joints, tongue and groove, lap joints, or even blind dovetails. Biscuit joinery does allow at least some intimate raw wood contact between the plowed area of the work piece and the biscuit, so that may be a consideration, as well. As for the glue, Gorilla Wood Glue is a non-foaming formula that works very well, as do any of the conventional PVA based wood glues on the market. On another note, you may want to consult with the maker of the pocket joinery tool as I believe they tout their joint as not requiring glue. I don't have one of their tools (yet), but from what I have seen, it creates a strong, tight joint without any glue at all. From my experience, it is always best to play around with several options and choose the one that seems best suited for your particular job. Hope this helps!<br /><br />Ang

I had to rip out my bathroom floor because of a leaky toilet. The plywood subfloor was wet and moldy. I want to replace the subfloor with "Hardibacker" backer board but I want to make sure it does not contain any volatile organic compounds.<br />Thanks.

bathroom floor Q# 2419 / Submitted 6/26/2010

The product you mention is manufactured by James Hardie Building Products and is not a Columbia Forest Products panel. I have checked their MSDS(http://www.jameshardie.com/pdf/msds-interior-medium-density.pdf) and it does not appear that the product you mention contains any organic material other than cellulose and carbon black, neither of which would be considered voaltile under normal use in a residence. However, neither I nor anyone outside the James Hardie organization can make any claims relative to any of their products, so I would strongly recommend you check with them before proceeding. Their contact information for general information as well as emergency info is included on their MSDS. I hope this helps!<br /><br />Ang

Columbia Forest Products does not manufacture T-111 siding as it is an exterior decorative siding panel. We manufacture interior grade hardwood and decorative softwood plywood panels that are usually further processed to make kitchen and bath cabinetry, furniture, and architcetural millwork for indoor applications. T-111 is produced by a number of softwood or structural plywood manufacturers. It should be readily available from almost any building supply outlet or big box home center such as The Home Depot.

Do termites like purebond plywood. thanks andreaspec@msn.com

termites/cabinets Q# 2403 / Submitted 5/12/2010

When most people use the word "termites," they are referring to the numerous species of subterranean termites that we hear so much about from the abundant pest control commercials that typically run on TV during the spring months. Indeed, this pest does more damage to homes in the US than is probably realized. They do eat wood...all kinds of wood...that are in contact with soil. Sunlight is fatal to termite workers so they must remain protected at all times. In order to gain access to homes, they must find their way though cracks in the foundation or slab floor, or construct "tunnels" of mud and wood fibers in those areas where no other access exists. Hardwood and decorative plywood panels, including those manufactured by Columbia Forest Products, are intended for use in interior applications such as furniture and cabinetry. As such, they should never be considered for any application where they would be expected to come into contact with the soil. In the event that a home has a serious infestation where an established colony of termites has found its way through the soil and into the foundation and subsequently the wood structure of a home, they could conceivably eventually work their way to the cabinets or other interior woodwork. If this were to occur, the homeowner would surely have discovered the infestation long before that.<br /><br />Now, to answer your question: PureBond panels are no more susceptible to termite infestation than any other interior wood product, including raw solid lumber and interior panels glued with any other adhesive, including urea formaldehyde, pva, or phenolic glues. Termites love wood, but it has nothing to do with whether or how it is glued together. Unless it is treated for use in contact with the ground, termites will eat it. Some species, such as aromatic cedar (Juniperus virginiana) spanish cedar (Cedrela spp), and western red cedar (Thuja plicata) have a natural resistance to insect infestation, but even they are not completely immune. <br /><br />Hope this helps!<br /><br />Ang

Can T-111 be used in place of 5/8 thick sheetrock on one side of a wall that is designated a 1hr wall?

T-111 Q# 2399 / Submitted 4/22/2010

T-111 is a decorative exterior product not manufactured by Columbia Forest Products. Typically, producers of this product are also softwood plywood manufacturers rather than interior plywood producers such as Columbia Forest Products. With respect to using T-111 in lieu of drywall to achieve a 1 hour rating, I would recommend that you contact the actual manufacturer of the product through your distributor or home center, or contact the American Plywood Association at apawood.org.

I am building some basic cabinets to cover some controll boxes. I am using pine for trim using Minwax Golden Pecan with a prestain wood conditioner. What type of plywood should I use to keep a consistant color/look? Oak, Maple, Sandply?

Staining Plywood Q# 2397 / Submitted 4/10/2010

Of the 3 species you mention, Sande (Brosimum spp.) from the Utile group comes closest in terms of porosity, but it is a much more coarse textured wood than pine. The other two are typically tight grained, particularly in the latewood of oak, and therefore would not be expected to take stain as would pine. Having said this, no one can guarantee that any finish will take the same in two different species. Indeed, it is often a stroke of luck that the stain takes the same in 2 different pieces of wood from the same species. Therefore, a little experimentation on scrap wood prior to the final finish is highly advisable!<br /><br />Best of luck with your project!<br /><br />Ang



I'm installing a built in wall oven in a lower cabinet. The oven calls for an adhesion spec of at least a 194

temperature exposure to prefinnished maple ply Q# 2396 / Submitted 4/6/2010

Our adhesive must be able to withstand temperatures of at least 250 degrees F as this is an average setting for most hardwood plywood glues to cure. The adhesive process results in a rigid thermo-set bond that has been shown to be able to withstand temperatures in excess of 500 degrees F, which is close to the autoignition temperature for many species of wood. However, our product standard does not require the manufacturer to rate the glue line as suitable for any given temperature as this determination is typically the responsibility of the designer. You may want to check with the Kitchen Cabinet Manufacturer's Association at www.kcma.org for assistance in determining a suitable design and for clarification on temperature requirements. Thanks for a great question!<br /><br />Ang

Yellow poplar (Liriodendron tulipifera) has a color range from blonde to purple, with green being the more common color for the heartwood.

24 CFR 3280.308 Formaldehyde emission controls for certain wood products Q# 2393 / Submitted 3/30/2010

Interestingly enough, I was intimately involved with the regulatory process that developed this particular regulation, and I can assure you that our PureBond MSDS will satisfy any reporting requirements established by it. In fact, the MSDS for PureBond does not list formaldehyde for a very simple reason, excepting for the infinitesimally small and virtually immeasurable amount of formaldehyde that may be released over time from the actual wood, the adhesive used for PureBond panels does not emit formaldehyde. Our MSDS for panels produced with substrates currently manufactured with urea formaldehyde adhesives does list formaldehyde, specifically referencing the HUD rule, indicating compliance with the regulation even for our products that actually do emit formaldehyde. <br /><br />But, to repeat, our PureBond products and the relative MSDS absolutely satisfy the HUD regulation.<br /><br />Thanks for a great question!<br /><br />Ang



Hi, Ang! We are trying to help some of our architect friends update their specifications. Please compare Classic Core to Europly for mechanical properties (e.g. MOR, MOE, etc) and for aesthetics. I'm guessing the machining used to make the Europly plys makes it more comparable to Classic Core outer MDF plys while maintaining the higher physical properties of standard veneer core product. As always, your help is appreciated!

Classic Core vs Europly Q# 2391 / Submitted 3/29/2010

Europly is Columbia Forest Products' multiple ply veneer core product produced with alder and birch components to exacting tolerances for thickness, smoothness, and soundness. It provides a very smooth surface directly under the face and back. Its edges are actually highly decorative in appearance, producing the classic "institutional furniture" edges that are so desirable today. The edges are generally clear and virtually free of voids. Classic Core utilizes traditional veneer core inner plies with the exception of the outer plies adjacent to the face and back, which are engineered components (MDF) as opposed to wood veneer. This core type is highly suitable for applications where veneer core is required, but where the surface quality of the components directly under the face and back is critical. Generally, the edges of Classic Core panels must be treated in some manner so as to conceal them from view.<br /><br />As far as mechanical properties, as you know I am always reticent to quote exact numbers as there is so much built in variation in the components. However, to give you some comparative numbers, Classic Core density from our testing ranges from 30 to 45 pounds per square foot, compared to Europly at 38 to 45 pounds per cubic foot. MOE for Classic Core ranges from 300,000 psi to 900,000 psi owing to the wide variety of species and thicknesses used for the inner plies, compared to Europly with a range of 800,000 to 1,000,000 psi. MOR for Classic Core varies from 7500 psi to 12,500 psi, compared to Europly at 8,000 to 9,000 psi. Screw holding for Classic Core ranges from 240-320 psi face, and 195-300 edge, compared to Europly at 500-550 face and 400-450 edge.<br /><br />Please know these values are not in any way representative of actual values that may be developed at any given time on any specific sampling of material. They are offered purely for comparative considerations. It is recommended that separate testing be conducted by the end user to determine the suitability of any product for any specific application where physical properties are critical. Hardwood plywood is sold as an interior, non-structural decorative product, and as such it is manufactured to an aesthetic standard, ANSI/HPVA HP-1-2004, rather than a mechanical standard.<br /><br />As always, thanks for your great questions!<br /><br />Hope this helps!<br /><br />Ang



Re: Carb P2 3/4 inch red oak purebond - for home installation as underlayment for a real linoleum floor-- How long should it acclimate? Thank you.

Acclimation time Q# 2386 / Submitted 3/19/2010

Actually, none of Columbia Forest Products panel offerings are intended for use as flooring underlayment. They are traditionally used for kitchen and bath cabinetry, interior millwork, paneling systems, fine furniture, and the like. I appreciate completely that your goal is to avoid formaldehyde, and our PureBond veneer core panels will certainly do that. However, we could not warrant the panels as suitable for the use you describe. You may want to check out the underlayment products that are intended for your use. They are manufactured with phenolic formaldehyde, which while still utilizing formaldehyde as a binding agent, releases so little into the air that they are considered safe by the regulatory agencies. <br /><br />Any panel product designed for interior use, whether as cabinetry, wall panelling, or underlayment should be allowed to acclimate to the in-service environment at least 72 hours if possible. Where extreme conditions between storage and in-service conditions exist (unheated warehouse in a cold climate to a heated home), this time should be extended to several days.<br /><br />Best of luck with your project.<br /><br />Ang



i want to bleach the T-111 to get the mold off. how much bleach do i use with water?<br /><br /> thanks

T-111 plywood Q# 2385 / Submitted 3/19/2010

T-111 is a grooved, rough sawn look, decorative exterior panel not manufactured by Columbia Forest Products. Our panels are produced in stock panel sizes to be processed into components for kitchen cabinets, fine furniture, interior millwork, store fixtures, and the like.<br /><br />Regardless, I have had success with mildew removal, and to a certain extent with mold removal using a commercially available product called Jomax, which can be found in most home improvement centers. The company recommends mixing one quart Jomax, 3 quarts chlorine bleach, and 4 gallons of water to make a 5 gallon solution that can be sprayed directly onto the entire wall surface, allowed to stand for a short time, then rinsed with tap water from a garden hose. It comes in a one gallon jug which will make 20 gallons of mixed solution. It is environmentally friendly and generally harmless to all but the most sensitive plants, which will be fine if covered with plastic during the application phase. Read and follow all instructions on the label and you should see satisfactory results. I can't make any guarantees, but it has worked well for me on vinyl, masonite, and yes, T-111!<br /><br />Hope this helps!<br /><br />Ang



Background for Ang Schramm: I represent an Architectural Ceiling Company. Our customer is experiencing

Green coloration, Eucalyptus Veneer, FR FSC NAUF MDF core Q# 2384 / Submitted 3/12/2010

Eucalyptus is a widely distributed genus of the family Myrtaceae consisting of many established and some naturally occurring hybrid species (Eucalyptus camaldulensis, E. cirtiodora, E. Maculata, E. delegatensis, E. obliqua, E. regnans, E.diversicolor, E. marginata, E. resinifera, E. grandis, to name a few). Originally, the range for this group included Australia and Tasmania, but it is now been established in Africa and South America. It is also known as Red Gum, Spotted Gum, Tasmanian Oak, Karri, Jarrah, Australian Red Mahogany, and Lyptus® (Weyerhaeuser Co.). It has been utilized for years for both decorative and structural applications. The origin of its use in the US is not known, but it has been in general circulation here for many years, albeit less frequently than the historically more popular millwork species like South American Mahogany (Swietenia macrophylla), African Mahogany (Khaya ivorensis), Anegre (Anningeria spp.) American Black Cherry (Prunus serotina), or American Black Walnut (Juglans nigra), to name a few. Eucalyptus generally resembles the mahoganies in gain, although the color may vary from almost blonde to dark brown to dark blood. It is a widely available alternative to the more eco-sensitive species, and is gaining popularity every day due to its versatility and attractiveness.<br /><br />Because of the wide area of distribution of the species, the potential wide range of sourcing, inherent variation between the individual species and indeed, within the same species from region to region, it would be difficult to determine if the veneer contributed to any staining or discoloration observed in service as described here. While no common discoloration concerns have been raised in the marketplace regarding this genus, there are a number of factors that could contribute to this condition under the right set of circumstances, including, but not limited to: the moisture content of the veneer, the open grain nature of the species that might be expected to allow moisture movement more freely, in-service temperature and humidity conditions, lighting, oxidants in the wood or finish materials, potential interaction resulting from migration of preservative or fire retardant compounds from the substrate, the presence of naturally occurring extraneous compounds in the wood, any combination of these conditions, or certainly even a cause not listed here. <br /><br />I hope you find this information useful. <br /><br />Ang<br />



I understand that CFP produces formaldehyde-free plywood for decorative interior applications. Do you have any recommendations for a formaldehyde-free product for subfloors? Is the phenolic exterior plywood the best bet for limiting indoor formaldehyde emissions from subfloors?

plywood for subfloor Q# 2383 / Submitted 3/11/2010

Subfloor panels on the market today are most often produced with a phenolic formaldehyde adhesive. While the glue formulation does utilize formaldehyde, the cured bond releases so little that it is considered safe by the regulatory agencies. It is not technically formaldehyde free, but any amount emitted would be indistinguishable from background levels of formaldehyde present in any environment. <br /><br />Ang



WHAT IS THE DENSITY PER CUBIC INCH OF 1/2" SANDEPLY? OR WHAT IS THE WEIGHT OF ONE 4X8 SHEET

DENSITY Q# 2382 / Submitted 3/2/2010

Columbia Forest Products does not manufacture that product, but if it is all sande in all plies, it probably has a density of somewhere in the neighborhood of 30 pounds per square foot with a lot of room for variation. This would place a 1/2" sheet's weight in the range of 40 pounds. This is a sheer guestimate as the density and specific gravity can vary greatly with moisture content, and actual panel thickness can also play a part. Hope this helps!<br /><br />Ang

The PureBond formaldehyde free panel products we manufacture are intended for decorative applications in an indoor environment. The adhesive meets ANSI/HPVA HP-1-2004 requirements for Type II Water Resistance, but it does not meet APA requirements for exterior applications, whether wrapped with a vapor barrier or not. We do not manufacture CDX. That product is manufactured by the structural plywood segment of the wood products industry to different specifications to be used in such applications as you describe. The adhesive used is typically phenolic formaldehyde, which, though technically isn't formaldehyde free, emits so little as to be exempt from reporting in most cases. It should contribute neglibly if at all to indoor air qualtiy or the lack thereof. Hope this helps!<br /><br />Ang



the contracter im working for used sandeply (4 by 8 sheets)and i used ml campells amazing stain and there krystal finish and the wood is flaking off and is blimishing bad. what is a goos solution for this thanks darryl

sandeply flaking Q# 2372 / Submitted 1/28/2010

If by "flaking" you mean the thin face layer is separating from the cross directional ply (cross band) under it, you are experiencing a delamination that is not related to the finish. This product is imported by any number of companies and is commonly sold in retail lumber yards and big box stores. You should contact the store where you bought it if it is indeed delaminating. As far as the finish, like any wood, sande requires proper surface preparation prior to application of stain and sealer. It should be sanded smoothly before the stain and sealer are applied, and between coats until the top coat is applied. To avoid excessive penetration in some areas, it may be necessary to pre-treat the surface with a glue size or a wash coat of sealer. Either of these penetrate into the surface where they dry to close the loose grain. Subsequent light sanding allows stain to penetrate, but not so much that it leaves the area blotchy. Thanks for your question!<br /><br />Ang



I have been looking all over and trying to find out exactly what kind of wood Sandeply is made from?? The only thing that I can come up with is that is mainly from South America. Is there anything that you guys know or a link that you can give me that will give the details of what this wood is.. Thanks for you time.

Sandeply Plywood Q# 2371 / Submitted 1/28/2010

Sande, also called "cocal," is from the genus Brosimum in the Moracaea family in the Utile group of species that are indigenous to South America from Costa Rica to Pacific Ecuador, with the majority exported from Colombia. It is very common, it seasons well, it is very machinable, so it makes an excellent utility grade lumber and veneer. It is converted to lumber and plywood by any number of local manufacturers for export to the US and elsewhere through a wide variety of distributors, and is common in most of the big box retail stores. If you Google "Brosimum spp." you should get more info than you can digest. Hope this helps!<br /><br />Ang



I installed a 3/4" oak veneer plywood bar top. it appears to be delaminating in a few spots after one week in use. the bar top was stained allowed to dry 6 hrs. then coated with spar urethane (about 5-6 coats) before being put into use. the spots that appear to be delaminating start at the edges then go toward the center in a "V" pattern.

oak bartop delaminating Q# 2370 / Submitted 1/26/2010

The term "delamination" in the context of a plywood manufacturer describes a failure of the bond between adjacent wood components (such as you have experienced) through any number of reasons, including too much glue, too little glue, too much heat, too little heat, too high a moisture content in the wood (which could be a small area or the entire component), and any number of other contributors. Without seeing the actual piece, it would be difficult to diagnose precisely. It would be difficult for you to cause the wood to delaminate through normal finishing processes. The adhesive for most hardwood and decorative plywood panels is formulated to meet the requirements of the ANSI/HPVA HP-1-2004 Standard for Type II water resistance. <br /><br />Delamination in the field can be repaired in some cases, but it takes a little time and can be tricky. You may want to try making a small slit in the delaminated area with a razor knife, then use one of the hypodermic devices offered by the woodworking catalog sales companies to inject white carpenter glue into the separated areas. You may want to use a household iron set to very low temperature to press down on the area to set the glue. If this fails, replacement of the offending component may unfortunately be your only remaining option if the delamination inteferes with the serviceability of your bar. If this is the case, you may want to contact the dealer from whom you purcahsed the panel about a replacement sheet.<br /><br />Hope this helps!<br /><br />Ang<br /><br />

Are the particle board in the kitchen bases that use Pure Bond formaldehyde free as well as the plywood construction.

Kitchen base and cabinets Q# 2367 / Submitted 1/18/2010

If you are referring to cabinets already in use, without knowing when the material was produced and for whom, it would be impossible to even speculate. Unless the specifier/buyer for the cabinet manufacturer specifically requested a No Added Urea Formaldehyde (NAUF) particle board core, the panels supplied would likely have been standard UF bonded core. The adhesive we use to bond the face and back to the core would be the same product we use in our PureBond panels. <br /><br />If your question refers to cabinets you are considering buying, we can supply a NAUF bonded particle board core for many sizes. At this time, there is usually a slightly longer lead time for these panels.<br /><br />Thank you so much for your interest in our PureBond panel products!<br /><br />Ang

Hello there - My question is this:<br /><br />I have read that your Hardwood Plywood is "Formaldehyde-Free", meaning that there is no added formaldehyde than what naturally occurs in the wood itself.<br /><br />I make large bunk/loft beds, and am considering using a one of your plywood materials for this.<br /><br />Now, I understand that there is still some level of formaldehyde emission from this material, and being that my product is quite large and will consist of many ripped pieces, is this still safe for indoor use? In other words, does being "Formaldehyde-Free" mean that you can SAFELY use ANY amount of this material indoors? My product will consist of many ripped pieces (about 40, average length of 70"); does the formaldehyde emit more through ripped edges? The last thing I want to do is subject my customers to something harmful!<br /><br />Thanks so much in advance. Any information is appreciated!<br /><br />Maurice

Urea Formaldehyde Q# 2362 / Submitted 12/14/2009

There is no formaldehyde used in our veneer core panels manufactured with our PureBond formaldehyde free technology. You are correct in that freshly sawn edges of panels manufactured with a urea formaldehyde adhesive would tend to emit more formaldehyde short term than the already exposed face and back surfaces. However, our PureBond panels are no different than solid wood and will not emit any volatile organic compounds in any measurable amounts even from the freshly sawn edges. The amount of formaldehyde emitted from the wood in our PureBond panels or even from solid wood is infinitesimally small, and difficult to distinguish from background levels that likely exist in ambient air in a neutral environment. Hope this helps!<br /><br />Ang

However, there may be circumstances or individual mills where this may not be the case. Your best bet is to check with your provider to make sure before you proceed. Additionally, it would be advisable to examine any panels in question to ensure the face is oriented as you expect. While some backs may occasionally have a really nice appearance to the point they could be mistaken for a face, if you look at the overall appearance within a given shipment, there should be a distinct difference between face and back appearance. The greater the difference between face grade and back grade, the easier this will be. For example, the face on a panel with an A grade face and a 2 grade back should be much easier to distinguish from the back. On a D-3 panel that difference may not be so easy to distinguish.



What would be the flame spread rating of maple veneer (less than 1mm). It would be applied to 9/16 birch wood.

Maple Veneer Q# 2360 / Submitted 12/10/2009

A thin veneer of any species would tend to contribute significantly to the flame spread rate if it were some how used in a stand alone application, or if it were to somehow delaminate from its substrate during the flame spread test. In this scenario, the flame spread would probably exceed 200, taking it outside the upper limit for Class C as set forth by the National Fire Protection Association NFPA 101.<br /> <br />When well laminated to an otherwise untreated wood or wood based substrate, as long as it isn



I want to use prefinished birch plywood for the boxes of kitchen cabinets I want to build. Where is the best place to buy 10 sheets of this product and what should I expect to pay for it.

finding plywood Q# 2358 / Submitted 12/5/2009

Your best bet is to conduct a dealer search from our site for a dealer or distributor in your area. We have distribution throughout North America and should have one near you. We make so many configurations of birch plywood in thicknesses from 3/16" to 1 1/2" thick with cores to include veneer, particleboard, and medium density fiber core in numerous grades, and we don't publish a suggested retail price for our distributors, so the prices will vary greatly depending on the aforementioned factors.

Is it true that the 3/4" europly that is manufactured at the Klamath Falls mill has a core that is manufactured in Russia? If so then is the adhesive used in the core panel also purebond or at least NAUF?

Origin of Europly core Q# 2357 / Submitted 12/1/2009

We currently purchase our Europly core blanks from selected mills located in Europe and Russia with a phenolic glue as opposed to the low fuming UF glue which was originally used when we began the program several years ago. With the phenolic adhesive the blank is considered NAUF.



I've stained walnut plywood with an oil based stain....the grain in the plywood in some spots appears to be rough....resulting in a blotchy look...help - help - help<br /><br />thanks

problem with stain Q# 2356 / Submitted 11/24/2009

It sounds like you are describing what we refer to as end grain figure, where the actual ends of the pores are open on the surface. Stains will "dive" into the wood in these areas, creating a blotchy effect. A treatment of a wash coat of a highly thinned sealer prior to stain is recommended when finishing fine hardwoods as it will penetrate into the open grain, but not be so apparent. Light sanding prior to staining will remove the wash coat from the flat surfaces but leave it in the end grain areas, giving them similar stain absorption characteristics. In the meantime, correcting what you have may prove difficult. You may try removing as much of the finish you have already applied with light sanding, but in all liklihood you will still have some darker blotches, even though the overall appearance should improve. Hope this helps!<br /><br />Ang



Hi, I need to know what the compression properties are for 3/4 Red Oak Plywood. Can you tell what it is as PSI?

compression properties Q# 2354 / Submitted 11/18/2009

If you are looking for compression perpendicular to the grain, we have to look at the value for the species of the cores rather than the species of the face. Assuming your interest is in a veneer core panel, the values if the core species are yellow poplar or white fir would be around 500 psi and for aspen it would be 370 psi as listed in Table 4.2 of the "Wood Handbook: Wood as an Engineering Material" Agriculture Handbook 72, published by the United States Department of Agriculture Forest Service. There are many variations and combinations of domestic and imported species used in the manufacture of veneer core decorative plywood, so these numbers should be considered as very general in nature with respect to your question. I hope this helps!<br /><br />Ang

firerating documantation for PureBond ply Q# 2352 / Submitted 11/12/2009

Our hardwood and decorative panel products are considered to meet Class C in accordance with The National Fire Protection Association Life Safety Code 101, which classifies flamespreads in the following manner:<br />Class A 0-25 flamespread <br />Class B 26-75 flamespread<br />Class C 76-200 flamespread<br />These numbers are based off a reference flamespread of 100 for red oak. The Smoke Developed Index of 450 or less for all classifications, common to most building codes, is also based off an SDI of 100 for red oak.<br /><br />The American Forest and Paper Association publishes a document called "Design for Code Acceptance" which lists actual flame spread results for numerous untreated wood products, tested in accordance with ASTM E-84. As can be seen by following the link: http://www.awc.org/Publications/dca/dca1/DCA1.pdf, most wood products easily meet the requirements for Class C, including the several hardwood and decorative softwood plywood panels tested. Because of the vast number of skus we produce and the logistics and costs associated with testing each individual product, for most of which no flame spread rating is ever sought, we do not have a standard document or certification relative to the fire rating or our products. Rather, we consider that due to the similarity of our product in general to the many products we have tested and the number of products tested by the AF&PA in the attached document, our product meets Class C, and this statement should suffice to satisfy any requirement from your trade show organizer. Even if we tested the exact product you are using, the test is destructive in nature, and you could not use the actual tested product. Any certification based on any actual test would state essentially what I have written here, and that is that products "similar" to the one you used were tested and found to meet Class C. Should such documentation be required, the Hardwood Plywood and Veneer Association offers the ASTM E-84 test for $575, plus the cost of the panels required for the test. I hope this helps!<br /><br />Ang

what is the differnce between plywood end and plywood. -- i purchased diamond

kitchen cabient t Q# 2340 / Submitted 9/28/2009

"Plywood" as we manufacture it is a general term that means any number of plies, usually 3 or more, of a variety of veneer or engineered wood components, usually having a very thin face and back veneer layer from one of the traditional decorative furniture or cabinet species such as maple, birch, oak, hickory, cherry, and many more, depending on your preference. It may be as thin as 5/32" and as thick as 1 1/2", and may be all veneer core, all particle board core, or all medium density fiber board core, or a combination of these.<br /><br />I am not sure about the term "end plywood" or "diamond" with no context for reference. End panels of cabinets are usually 3/8" to 1/2" decorative plywood, and this may be your meaning. Diamond may refer to a distinct pattern achieved by a painstaking process of orienting face inlays so that the overall surface has a diamond pattern, but diamond could also refer to a veneer provider. I am just not sure. <br /><br />Hope this is useful information. <br /><br />Thank you for your interest in Columbia Forest Products!<br /><br />Ang

Our PureBond hardwood panels are not designed for use as underlayment for wood or bamboo flooring, but rather as decorative panels in cabinetry, furniture, or wall paneling. Your best bet would be to use one of the softwood plywood tongue and grooved products designed for that application. They are produced with phenolic based adhesives that are very low formaldehyde emitters, so low, in fact as to not be regulated under any of the regulatory bodies that address formaldehyde. Even so, the panels should be allowed to acclimate on the job site for a period of 2-3 days to ensure stability. <br /><br />Thank you so much for your interest in our PureBond formaldehyde free decorative plywood panels!<br /><br />Ang

Where can I buy 3/4" marine plywood .I live in Drexel Hill,PA 19026.

marine plywood Q# 2334 / Submitted 9/4/2009

Marine grade is a designation of the American Plywood Association which represesnts softwood or structural manufacturers. As producers of hardwood and decorative softwood plywood panels for interior aesthetic applications rather than structural applications, we do not manufacture a "marine grade" panel per se. However, we do make decorative panels for marine interiors for special order to customer specifications. If this is what you are seeking, your best bet will be to conduct a dealer search from our website for a dealer or distributor in your area. Since panels we produce for marine applications are subject to customer specification, we don't make a "stock" line of panels, so you will need to provide your specific requirements to the dealer and your panels will need to be special ordered. If, on the other hand, your needs may be met with a structural or softwood plywood panel, your local dealer can probably purchase marine grade from their softwood plywood vendor if they don't carry that product in stock. Thank you for your interest in Columbia Forest Products hardwood and decorative plywood panel products!<br /><br />Ang

formaldehyde Q# 2333 / Submitted 8/21/2009

For all intents and purposes, the number is zero. We have tested panels in accordance with methods prescribed by the American Society for Testing Materials (ASTM) E-1333, and produced results from zero to no more than 30 parts per Billion...that's ppb, not ppm, and this number is often used as "background" levels that are likely present in the test chamber when it is empty. If you are interested, California Air Resources Board (CARB) documentation (which includes individual mill certificates and exemption executive orders) for all Columbia plywood manufacturing plants is listed online: http://www.columbiaforestproducts.com/CARB.aspx.<br /><br />Hope this helps!<br /><br />Ang



We purchased pre-finished maple 3/4" plywood for kitchen cabinets. Our plans call for a 1/4" x 2" overlay that is to be glued to the finished surface around the end panels to give the appearance of rail and styles. How can we glue these to the pre-finished surface?

Plywood Q# 2331 / Submitted 8/14/2009

A UV cured finish is not intended to be bonded to other surfaces, and we do not make recommendations as to how this can be accomplished. The difficulty you will face is the hardness and near impermeability of the finish. If you are able to scuff through the finish to the raw wood with an aggressive grit sanding paper, you may be able to achieve satisfactory performance with ordinary white carpenter glue. Follow the glue manufacturer's directions for gluing wood to wood surfaces. This will be tricky, at best, but with a little elbow grease and some luck, you may be able to pull it off. <br /><br />Ang



I would like to know if at its end of life, PureBond plywood is recyclable. I see the question from 10 Dec 2008 about composting wood filings/dust, but I would like to know if the plywood itself is compostable or recyclable.

end of life Q# 2330 / Submitted 8/10/2009

The short answer here is no to the extent that there is no site any one anywhere can go drop off panel products in a bin designated as such. Our panels may be recycled through other means such as donations to Housing for Humanity. They will reuse any panels that they can and send what they can't to be chipped and reduced to mulch. If reduced to saw dust or small wood chips it should be compostable. If possible panels should be left in their original form to minmize the release of carbon into the environment. <br /><br />Ang



Our company manufactures, among other things, large boardroom tables. Usually these have a 1" birch plywood subtop. On a recent project with a stone top on such a subtop, there seems to have been expansion of the plywood subtop, which is approximately 26-1/2 ft. long x 11 ft. wide. In a controlled atmosphere such as an office (30-50% RH, we are told), how much could the plywood have moved? According to our records, humidity here in the shop was about 25-30% when the subtop was manufactured. Thanks for any help you can give.

Expansion of plywood in offce furniture Q# 2328 / Submitted 7/20/2009

Because all wood is a hygroscopic material that takes on or gives off moisture freely, any wood product is likely to expand and contract over time, even with mild variation in in-service conditions. This is why, for example, it is always recommended to incorporate a reveal between panels in an architectural wall system, or why it is recommended that table tops not be screwed or glued down to the frame, but rather be attached so as to allow movement as the wood expands or contracts. There is no provision in the hardwood plywood standard, ANSI/HPVA HP-1-2004 that addresses linear expansion, but ANSI A-208-1 and 208-2 standards for particle board and MDF allow for 0.3% to 0.35%. Assuming veneer core plywood would perform likewise, over 132" width, you could see expansion (positive or negative) within a range of 0 to 0.462" or just over 7/16". While this extreme movement would not be expected under controlled in-service conditions of 25-55% rh and 68-75 degrees F, one should expect that some movement will take place. Hope this helps.<br /><br />Ang

Where can I locate information that explains how faces are rated and/or graded. Or explains the difference between an A1 and an A4 panel?

understanding panel grades/ratings Q# 2326 / Submitted 7/17/2009

The Hardwood Plywood and Veneer Association in Reston VA, 703-435-2900, www.hpva.org, should have the information you want. Most hardwood and decorative softwood plywood panels, including those produced by Columbia Forest Products, are manufactured in accordance with the voluntary product standard, American National Standard for Hardwood and Decorative Plywood, ANSI/HPVA HP-1-2004. This standard establishes nationally recognized marketing classifications, quality criteria, test methods, definitions, and product marking designations for hardwood and decorative plywood. <br /><br />To explain the face and back grades in a nutshell, the standard lists 6 face grades with AA being the highest and E being the lowest. AA grade is typically almost free of any natural characteristic that would detract from the over all appearance, including knots, color marks, bark pockets, or roughness, with each successive lower grade having progressively more such characteristics visible. There are 4 back grades with 1 being the highest and 4 being the lowest, selected in a similar, though much more liberal manner than faces as previously mentioned. The selection process is done by highly skilled and trained personnel with lengthy experience in grading veneers.<br /><br />For your example, an A-1 panel has an A face, meaning it has a very attractive appearance with few distracting natural characteristics and a #1 back, which, while not as attractive as the face, has a generally pleasing appearance. It is typically used where the face is exposed all the time and the back is occasionally exposed, as in the side of a cabinet or book shelf unit. An A-4 panel has an A grade face just as the A-1, but the back is noticeably character marked, having large open knots, no limit to color appearance, liberal unrepaired splits, and the like. An A-4 panel is typically used where only the face is exposed, such as with a wall panel.<br /><br />Hope this helps!

Is CFP beaded panel acceptable for use in a bathroom wall covering application?<br /><br />Is painting only the exposed surface acceptable?<br /><br />Are there additional painting recommendations you could make for a bathroom application?

beaded panel Q# 2325 / Submitted 7/15/2009

We warrant our decorative beaded plywood panels to be free of defects at time of shipment, but because of the relatively unlimited number of uses for this type panel, we cannot guarantee their suitability to any application beyond our control, and make no warranty beyond that mentioned above. Having said that, our panels are frequently utilized as components in kitchen and bath fixtures, and in such applications typically perform quite nicely. As far as the beaded panels are concerned, you should know that the machined bead leaves that area vulnerable to moisture penetration, so you should certainly consider that before you use it in a bathroom application. I think it is a common practice for builders to install unfinished panels prior to finishing, leaving painting the exposed surfaces your only option, but to help retard the penetration of water from behind the panels you may want to finish the unexposed surfaces prior to installation. I hope this helps!<br /><br />Ang

Humidity information Q# 2322 / Submitted 6/23/2009

We don't offer humidity control systems, but recommend that our products or products made from our panels be used or fabricated in an environment controlled to between 25% and 55% relative humidity at a temperature range of 65 degrees F to 75 degrees F. A humidification system manufactured by others is typically required to maintain such conditions. I Googled "commercial humidification systems" and got quite a few hits. The major manufacturers should be familiar with wood working environments and requirements and should be able to help you design a system that will meet your needs.<br /><br />As far as a company to provide on-site testing, a system manufacturer would probably be capable (and also quite willing) to do that for you. However, testing yourself is actually quite economical and very easy. The most accurate way to check relative humidity is with a sling psychrometer, available at most scientific equipment supply houses that are accessible on line. This simple device utilizes side by side thermometers. One is designed to be fitted with a supplied small wick that must be dampened with distilled water. The device is then rotated rapidly by hand for several seconds, the temperature differences between the dry bulb and wet bulb recorded, and the process repeated until such time that the difference between the two doesn't change from the time before. This difference is the actual difference, and it can be taken to provided chart that shows the "wet bulb depression" number at the dry bulb temperature on a spread sheet. The matching number at the point where the column and rows cross is the actual RH. <br /><br />Since relative humidity is a value representing the relationship between the amount of water in the air and the amount of water the air can hold at that temperature, it will change, sometimes dramatically throughout the day, and thus should be checked frequently.<br /><br />Hope this helps!<br /><br />Ang

what is the diff between rubber wood in india and your products

rubber woods Q# 2316 / Submitted 6/11/2009

Rubber wood is the name of a tree species including Hevea brasilinsis that is planted in southeast Asia, South America, and the Pacific rim islands. It is managed in plantations for its sap which is used to make latex and rubber. When the mature trees have outlived their productivity, they are harvested and reduced to saw timber. The resulting lumber is used to produce furniture, and even the short pieces that would have been considered as waste in the past have in more recent years been glued up to produce wider and longer pieces for use in furniture imported into North America. The difference between it and our products is that it would generally be used in solid form, including larger surfaces due to the fact that it is glued up side to side and end to end. Our panels are assembled from a wide variety of decorative wood species for exposed surfaces, and an assortment of substrate materials to include layers of veneer from more inoccuous species like spruce, pine, fir, yellow poplar, aspen and basswood, in addition to engineered cores like particleboard and medium density fiber board. Our products are typically purchased for fabrication into cabinets, fine furniture, architectural millwork, and the like, while rubberwood is usually used for price point furniture and furnishings.

plywood for museum use Q# 2315 / Submitted 6/9/2009

To my knowledge neither birch (Betula spp.), aspen (Populus spp.), nor yellow poplar/tulipwood (Liriodendron tulipifera) are known to off-gas any appreciable levels of volatile compounds that would tend to make them unsuitable for use in museum display cases. With respect to finishes, inasmuch as I am not a finishing expert, my best recommendation would be to have you consult someone who is. Our own Jeff Jewitt, accessible through our Ask the Expert page on our site, is a reknowned expert in the finishing field, so I would certainly start with him. If he isn't comfortable recommending a finish, he can certainly point you in the right direction. Thank you so much for your interest in Columbia Forest Products!<br /><br />Ang



what is the comparitive modulus of softwood vs harwood plywoods?

modullus of plywood Q# 2314 / Submitted 6/2/2009

Physical properties can vary within a given species or group, and even in wood from the same tree, so any answer provided here should be considered as a very rough estimate and not a precise value. Your question is further compounded by the fact that while softwood plywood is almost always composed of species in the spruce/pine/fir group, veneer core hardwood plywood may have cores from this same group, from hardwoods from South America, Africa, or the Pacific rim, from domestic hardwoods including poplar, aspen, gum, sycamore, and others, to a combination of any number of hardwoods and softwoods. <br /><br />In consideration of the foregoing, modulus of rupture, the maximum bending load to failure, will vary in softwood plywoods, probably somewhere in the range of 3000 to 6000 psi. In hardwood plywood utilizing all softwood inner plies, that range will probably be about the same. If the core is all hardwood, the range will increase a little, probably somewhere between 4000 and 8000 psi. All these numbers will also vary depending on the orientation of the grain relative to the applied force.<br /><br />Modulus of elasticity, a measure of the effects of applied stress relative to recoverable distortion, will vary in softwood plywood probably within a range of 400,000 to 1,000,000 psi. Likewise for veneer core hardwood plywood using all softwood inner plies. For veneer core hardwood plywood using all hardwood innerplies, that range may be a little higher, somewhere around 500,000 to 1,000,000 psi.<br /><br />Thanks for a great question! Hope this helps!<br /><br />Ang

Going to use your pre finished plywood to build kitchen cabinets, what saw blades gives best results.<br /><br />Thanks Erwin

saw blade for smoothes cut on pre finished plywood Q# 2312 / Submitted 5/28/2009

Your best bet for advice on saw blade selection would be your tool supplier. He or she should have the expertise to recommend a saw blade that would best fit your particular machine and equipment. If that is not an option, my suggestion would be to check with any of the major DIY blade suppliers, including Forrest, Freud, DeWalt, or Makita, just to name a few. There are blades specifically made to saw decorative plywood, but if these are not avaialble, a high tooth count combination blade should perform satisfactorily. I don't know your particular situation, but if you have the flexibility and time, placing a wide strip of masking tape along the line of the cut on both sides prior to sawing, and orienting the finished side so that the blade cuts into the finish side rather than the unfinished side will go a long way towards providing a very acceptable cut. Thanks for a great question!<br /><br />Ang



I found some plywood in the hardwood plywood section of Home Depot that listed the name as AGRATHIS. Do you have any idea what this is? I was looking for nomial 3/4 inch bierch plywood in a funiture grade.

Plywood name Q# 2310 / Submitted 5/22/2009

I suspect that what you saw was Agathis, probably Agathis australis, or kauri pine, not likely manufactured by Columbia Forest Products. This genus is indigenous to Australia, New Zealand, Fiji, and other Pacific rim countries. As a decorative plywood face it serves both an aesthetic and utility purpose. It is a softwood having a color range from pale to khaki, to pink, to dark reddish brown. It has a fine texture and can take stain and sealer coats well. It should not be considered an alternate species to birch (betula spp.), but it can certainly be used in furniture manufacture. Hope this helps!<br /><br />Ang



Do you sell formaldehyde-free plywood underlayment? If so, can you suggest a Chicago retailer?<br />Than you,<br />Roger Hughes

Formaldehyde-free plywood underlayment Q# 2308 / Submitted 5/15/2009

We manufacture a wide variety of decorative panel products, but we do not manufacture structural panels such as underlayment. However, most underlayment is manufactured with a phenolic formaldehyde glue that is so effieicnt at binding the formaldehyde in the finished product that there is so little free formaldehyde to off gass that PF bonded products are considered safe by the most stringent regulatory bodies.

I'm helping you earn your not-high-enough salary! I find most plywood manufacturers are very poor at providing mechanical information regarding their products. I'm talking things like MOE, MOR, screwholding for both face and edge, water absorption, etc. In fact I am looking to promote one of your new panel products soon and need those characteristics. I also don't find any reference to standards for this information in the HPVA HP-1 American National Standard for Hardwood and Decorative Plywood. In addition, architects in my niche market are beginning to ask manufacturers for info to help them understand the best application uses of the different type of plywood cores. It is not often they actually want to understand something so when they ask, I'd really like to be able to help. That is where mechanical characteristics comes to play again. I realize there will always be some plus/minus but we need what in our company we call "horseshoes close" info. It has to be close enough to score points without having to be a dead-on ringer. There must be someplace this information is available. Once again, can you help me? Thanks!

plywood mechanical characteristics Q# 2306 / Submitted 5/7/2009

I think what you experience with most plywood manufacturers (with reference to decorative panel products manufacturers



My company has not experienced this problem but a competitor has. The competitor claims they are having both face veneers delaminate and plywood split due to the CARB-compliant glues now in use. Now, none of our other comepitors have experienced this either. Our firm has already converted to the use of 100% CARB compliant material. Yet some key architects in my industry segment are looking to me to explain what is going on. I have heard some of the CARB-compliant glues have more water in them than others. When a completed building has an air-flush (lower humidity, higher temperatures) of the building to meet LEED requirements it causes the moisture to want to escape the plywood, causing splitting and delaminating. Again, we have not experienced this but I hear rumors. (It may also be - gasp! - that our competitor is intentionally using lower quality and cost materials and then avoiding responsibility by blaming his low quality on the CARB glues.<br /><br />Any thoughts? Once again, thanks for the help. This service of yours is a great help to the industry.

plywood splitting due to CARB glues Q# 2305 / Submitted 5/6/2009

There is always a lot of buzz surrounding any change that takes place regarding decorative panel manufacture, so this is nothing new. I have heard all the same rumors, which, and you may find this hard to believe, are not unlike those pervading the industry when UF glues were modified in the early 1980s to accommodate the then tighter emission standards passed by the US Department of Housing and Urban Development (HUD). While hiccups are always anticipated during the research and development stage preceding changes in adhesive technologies, these should be out of the system by the time it hits the market for general consumption. Additionally, even established adhesive systems will fail from time to time, in many cases more often than newer glues. However, because the newer CARB compliant adhesives are so new, many eyes are, pardon the expression, glued to their performance, and any failures, isolated or, in rare cases, more extensive, give pause for concern.<br /><br />I can't speak for other manufacturers' formulations, but the adhesives used to produce our PureBond® panels have actually outperformed urea formaldehyde bonds in our routine testing more often than not. <br /><br />As far as in-service failures, amount of water in the glues, etc: even UF glues typically consist of up to 45% water. It isn't the water that causes in service failures. More often than not, a well bonded panel, produced in accordance with established procedures, will not fail. Rather, failures in service can usually be traced back to deviation from those procedures. <br />Extremes of humidity and temperature can and often do affect panel stability, which can result in the introduction of stresses that can cause failures in a bond already weakened by poor procedures, but these stresses would not be expected to cause a failure in a bond resulting from closely following all procedures. <br /><br />As for surface checking, again the water in the glue isn't the issue as any free water is flashed off during and immediately after the pressing process. Here, extremes in temperature and humidity can actually be the culprit, but since ambient air in in-service conditions usually ranges between 40-60% relative humidity, and temperature usually ranges between 70 and 78 degrees F, I wouldn't consider that extreme. However, during the cold months, especially in colder regions of the country, extreme variation in storage conditions versus fabrication conditions versus in service conditions could be so great as to cause rapid surface moisture loss even in solid wood to cause surface checking unrelated to glue performance.<br /><br />I hope this helps! Thanks for always posing such pertinent and pensive questions!<br /><br />Ang<br /><br /><br />



I am looking for a superior core to veneer to, something with a consistent thickness hardwood ply core with thin (1/8") mdf faces. I've been told that your classic core is such a product but the CFP website doesn't describe it quite like this. Exactly how is classic core configured. I am looking forward to your responce. Thanks, Steve Turino

classic core Q# 2304 / Submitted 5/1/2009

Typically, our Classic Core panels are produced with all veneer core inner plies, laid up with the grain directions of adjacent layers alligned at right angles to each other, and a thin layer of an engineered wood product, usually MDF, directly under the face and back. The result is a panel with a very smooth and void free surface directly under the face. We produce Clasic Core in a wide variety of configurations, so it is advisable that you contact a distributor in your area through a dealer search available on our site, for more specific information. Thank you so much for your interest in our Classic Core panel products!<br /><br />Ang



did the mussels help to do the glue?<br />what materials do you use to make it?

mussels and glue Q# 2303 / Submitted 4/30/2009

The mussels to which you refer gave the inventor of our system the idea. His research revealed how it is that mussels are able to attach themselves to rocky outcroppings or piers and withstand the relentless pounding of the surface without, pardon the expression, coming unglued. He was able to mimic the biological compounds produced by the mussels to the extent that they could be produced commercially using environmentally friendly compounds that are safe for both our employees and end users. The major components are proteins such as those found in soy bean flour, and a wet strenth additive so common as to be found in everything from money to facial tissue.

I put dark wallnut stain on a plywood back of a clock and it looks like a zebra. What did I do wrong?

staining plywood Q# 2302 / Submitted 4/29/2009

What you are describing is a condition called "barber poling" that results from the differences in surface characteristics between adjacent components in a wood veneer. As a piece of veneer is sliced or peeled from a log, the side of that piece of veneer adjacent to the knife will develop tiny fissures or cracks known as lathe checks. The side with lathe checks is called the loose side. The opposite side is called the tight side. Book matching, a common method of joining pieces of veneer from a log to produce a full width face, requires that every other piece of veneer be turned over, producing a mirror image at the splice joint. This also has the effect of alternating the tight side and loose side across the face. The loose side tends to absorb more finishing material than the tight side, so that it looks darker. The end result is what you describe. The most common method of minimizing the effects of tight side/loose side is to glue size or wash coat the surface prior to finishing. This technique requires applying a very dilute mixture of glue and water or sealer and solvent to the surface before sanding. The glue size or wash coat will penetrate the loose side more than it does the tight side. Once dry, the surface can be sanded thoroughly, resulting in removing most of the sizing from the tight side while leaving it in the lathe checks on the loose side, thereby creating more uniform absorption charateristics across the entire panel.<br /><br />Ang



I need an expert in chemical engineering to explain how the off gassing takes place.<br />Thanks<br />Larry Dearman<br />907-841-9880

formaldehyde in my 5th wheel Q# 2301 / Submitted 4/28/2009

I am far from a chemical engineer, but I can tell you that formaldehyde is a building block for more products than you could ever list. Many products, including paints, common household cleaning supplies, money, cosmetics, and others just as common emit formaldehyde. In building products, it is often combined with urea to make a very strong bond between wood components. The problem is that once the bond is formed, all the formaldehyde molecules needed to form the bond do not become bound at the molecular level, and these "free" molecules will off-gas over time. When allowed to accumulate in the absence of good circulation, levels of formaldehyde can become quite high, producing acute symptoms including burning in the nose and throat and itchy, watery eyes. At high levels it is considered a carcinogen by several recognized regulatory and non-governmental agencies. <br /><br />For more information, you may want to Google formaldehyde. You should get almost 6 million sites, but the first several are connected to those agencies such as HUD, EPA, and OSHA, and you should be able to get an abundance of info from those sites. Hope this helps!<br /><br />Ang



Will I find that Europly or Jaycore noticably flatter than purebond? <br /><br />Thank you

CF Plywood Flatness Q# 2300 / Submitted 4/27/2009

PureBond is the registered trade name for our formaldehyde free adhesive technology. Europly is a registered trade name for a veneer core blank mannufactured by a vendor in Europe with a CARB Phase 1 adhesive system that is not the same as ours. Jaycore is a registered trade name for a veneer core blank manufactured in North America by Columbia Forest Products utilizing PureBond technology. Both panel types, when manufactured according to established processes should produce a flat panel. However, there are so many variables relative to moisture movement, in service conditions, manufacturing, construction choices, core production, shipping, and warehousing that ensuring a totally flat panel under any conditions would not be prudent.<br /><br />Ang



Hi, We are remodeling our basement and I am looking for rough-grade softwood plywood to build our subfloor. I'm prepared to pay extra for formaldehyde-free product, but I don't want to pay for a veneer since we will cover it with flooring anyway. Do you make any PureBond softwood plywood? Do you know any manufacturer who does? Thanks!

Formaldehyde-free softwood plywood for sub-floor Q# 2299 / Submitted 4/20/2009

We do not manufacture softwood plywood, and can't warrant our decorative panels as suitable for underlayment. However, most underlayment is produced with a phenolic formaldehyde adhesive that is so very efficient at binding formaldehyde at the molecular level that off-gassing is all but eliminated. In fact, I believe such panels are not covered by any current standard because their levels are considered de minimus, or so low as to not be of concern. I hope this helps. I am sorry we couldn't help you with an application for our PureBond formaldehyde free panels this time, but sincerely appreciate your thinking of Columbia Forest Products! Please keep us in mind for future decorative panel needs!<br /><br />Ang



Okay, with my last question you helped me better understand what "rift" REALLY is. Now help me ensure I don't get in trouble with quartersawn. An architect wants cherry with parallel grain and so has specified quartersawn veneers. He is referring to an AWI publication touting quartersawn as providing parallel grain and he expects it to all be parallel, with no "V's" as with plain sliced. Is that realistic? Does quartersawn assure us of parallel grain? Do we need to specify slip match to help ensure no V's? Thanks for your help.

parallel grain: rift vs quartersawn Q# 2298 / Submitted 4/15/2009

For all intents, the information on false rift versus true rift is effectively applicable to the difference between false quarters and true quarters. The tricky part comes when we don't have all the information we need to meet an end user's expectations, but the phrasing of your question is very helpful. A tree grows by developing wood in what essentially looks like a series of cones or inverted Vs in a nested fashion year after year. This means there is a natural "lean" or slope to the grain. In rare cases the grain is so straight as to meet the extremely difficult (and usually so high priced that most vendors won't quote it and most buyers opt out if they actually get a price) specifications of "comb" grain, meaning the slope of the straight grain relative to the edge of the component can not exceed 1/2" in 12." The spec for "sweep," or the amount of deviation from a straight line is the same in comb grain, essentially meaning no sweep would be allowed. Even with so strict a tolerance, there is just not much way to completely avoid a "V" appearance at the splice line in a book match of quarter sliced veneer. Depending on application, a slip match may better serve the purpose if the veneer is specified and priced with minimum slope and sweep, but unless the grain is perfectly straight the full panel may create an off balance look. Another option, although more expensive than traditional slip or book match is what we call a "slip and swing" where every other component is swung around 180 degrees without flipping it over. In any event, a good discussion with your supplier, the architect/specifier, and the plywood and veneer manufacturer together would be indicated to ensure your architect's expectations are met relative to what the wood can produce. Thanks for a great follow up question. It is so very important to have these discussions!<br /><br />Ang



I want to know the kind of finish that is used in manufacturing prefinished plywood. An intriguing feature of it is that it wll take pencil marks easily, unlike most shop-applied finishes.

kind of finish on prefinished plywood Q# 2294 / Submitted 3/31/2009

Essentially, our finish is an acrylic polyurethane with an ultra violet reactive agent that allows it to set upon exposure to specific wave length uv radiation under controlled manufacturing conditions. The resulting finish is highly water, chemical, and scratch resistant and perfectly suited for furniture, cabinet, or similar applications. In the semi-gloss and lower gloss levels, it will take pencil marks, which can be an advantage if you are marking measurements on the surface for sawing purposes. Any remaining pencil marks are easily removed with mild cleansers or a simple eraser without damage to the wood or finish. Some of the high gloss, high molecular weight coatings you have seen from other sources harden to an almost glass-like consistency, eliminating the friction necessary to allow for transfer of graphite from a pencil "lead" to the surface, especially in the highest gloss levels. Hope this helps!<br /><br />Ang

I just received a unit of prefinished walnut veneer Europly. The walnut (rotary cut) is very light, certainly much lighter than any American black walnut I've ever seen. What species is this?<br /><br />Thanks,<br />Scott<br /><br />(I was pleased to see the core is back to the classic "baltic birch" look with dark glue lines. Please keep it this way! My last batch had a very pink core with no visible glue lines, and was very fuzzy when cut.)

Walnut Veneer Species Q# 2289 / Submitted 3/27/2009

I apologize in advance, but without additional information, I can't make any kind of positive identification on the veneer you have received. In order to do so, I would need to know the mill from which it originated, the date of manufacture, the distributor for whom it was produced, and photos, if available. I can say with certainty that to Columbia Forest Products, the trade name walnut means American Black Walnut (Juglans nigra), and unless a rare (but still possible) mistake was made, that is what you should have received. I am a little concerned relative to the reference to the cut. Typically, walnut is available as plain sliced or quarter sliced, and only rarely have I seen it rotary cut. That doesn't mean you don't have rotary, it simply means that isn't a common offering from us or most hardwood plywood panel manufacturers. <br /><br />As far as appearance, Juglans nigra heartwood color ranges from an almost blonde to a mid-range brown when first cut. Typically, the traditional darker color is reached only after the steamed log has an opportunity to darken through a natural oxidative process that takes place over 24 to 72 hours after the veneer is cut and prior to its entering the dryer. Once dried to under 12% moisture content, the color achieved will be fixed. <br /><br />I know this is a lot to throw at you, but if you could please provide the additional information requested, we can have the producing mill in our organization back track the order so as to provide an accurate identification for you. <br /><br />I am sorry you have experienced a concern here, and hope to resolve it very soon. <br /><br />Thank you for specifying Columbia Forest Products!<br /><br />Ang



I've always believed when someone asks for "rift" veneers, it automatically tells you how the veneer is cut from the tree and what the resulting appearance will be, say in red oak. We have a distributor for a major manufacturer telling us that 90% of the "rift" used in our industry is actually a "false rift" made from plain sliced material. I find this disingenuous at best, unethical at least, and intentionally misleading at worst. Am I wrong?

Is the vertical face grain more ridged than the horizontal grain when constructing a stud die wall?

Plywood tensile strength Q# 2282 / Submitted 3/12/2009

The term "Tensile strength" typically refers to a measure of the resistance of wood to forces directed across the grain. While these values tend to vary greatly depending on species and construction (and the combinations are staggering), most testing done on plywood panels would tend to demonstrate a slightly greater modulus of rupture and modulus of elasticity across the grain versus parallel to the grain. Because of the many variables involved, however, it is generally accepted that the designer of any product should make the necessary determinations as to the suitability of any wood product for their specific application.



Hi, my contractors have installed the purebond plywood behind my radiators and I am concerned that your product may offgass (maybe epichlorohydrin) is this a concern? I have two small children.

purebond next to radiators Q# 2281 / Submitted 3/12/2009

Eri, inasmuch as heat tends to exacerbate the rate of off-gassing of volatile organic compounds (VOCs), you are certainly reasonable in your concerns. My best response and assurance comes from the fact that we have tested our panels for total VOC presence (TVOC) in accordance with Section 01350 of the Material Specifications adopted by the Collaborative for High Performance Schools (CHPS), receiving a "meets requirements" notification from our accredited contracting independent testing agency. This rating indicates no levels of epichlorohydrin above the 3 micrograms per mililiter threshhold established for that compound were recorded under extensive laboratory testing conditions. Given the nature of alternative materials and the established safety record of our PureBond formaldehyde free products, there would not seem to be any elevated health risk in leaving the panels in place.

E1 and E2 are European Standard references with E1 permitting 0.1 ppm and E2 permitting 1.0 ppm.<br /><br />For comparison, the California Air Resources Board (CARB) has recently implemented standards requiring hardwood plywood panel products to emit no more than .08 ppm in 2009 and .05 ppm in 2010. <br /><br />As far as actually obtaining a copy of the various standards, you may want to contact the Hardwood Plywood and Veneer Association (www.hpva.org), 703-435-2900. They should be able to advise you on how to obtain copies if they are avaialble. <br /><br />Thanks for your interest in Columbia Forest Products!<br /><br />Ang



An architect recently mentioned they are seeing delamination of face veneers on cabinets during hot air flushing of buildings. The flushing is done to rid the building of VOCs, formaldehyde, etc., before occupancy. The temperature is raised to 80 degrees or more and humidity made almost non-existant. The core material they use is a combination core (veneer core with mdf "j" layers under the face veneers). They have been told the delamination is a result of the use of CARB-compliant glues. They asked me for advice.<br /><br />So, have you heard of this? What do you suggest I tell them? Thanks; your answers are always a great help.

delamination due to CARB and hot air flushing Q# 2272 / Submitted 2/16/2009

While the conditions you describe are anything but suitable for decorative panel product exposure, they should not be so extreme as to cause a properly applied plywood bond to fail if the duration of the exposure isn't excessive. However, such exposure can and almost certainly will result in the development of extreme tension on any wood product to the extent that the wood, which is hygroscopic (freely gives off or takes on water in molecular form) in nature, will experience a rapid loss of surface moisture. Additionally, because wood is anisotropic, having different properties in different directions, any contraction that would result would likely be in different directions, thereby exacerbating any stresses. These stresses thus developed can cause joints to open, panels and doors to warp, and inserts to contract. In the event the bond on panels exposed to these conditions was somehow weak, these stresses could cause it to fail. This would be the case with any wood adhesive, "pre" or "post" CARB. I understand the need to flush any residual volatile materials from the air prior to occupancy, but I would strongly recommend a more wood-friendly method.<br /><br />Thanks for a great question!<br /><br />Ang

formaldehyde free Q# 2271 / Submitted 2/10/2009

We are not aware of any sub-flooring products manufactured with zero formaldehyde, but most are using a Phenol based system that is so efficient at binding the formaldehyde that the free formaldehyde available to off-gas is considered below the de minimus levels required by any current regulations for reporting. You may want to check with the American Plywood Association at apawood.org to see if any of their members are manufacturing a sub-floor grade panel with a formaldehyde free adhesive. <br /><br />Regarding your interesting reference to low level toxins, I have passed this along to our folks and appreciate your sharing with us! <br /><br />Thank you so much for your interest in Columbia Forest Products' formaldehyde free panel products.<br /><br />Ang



I spec'd Columbia pure bond plywood for an upcoming project. Architect has requested that this be a minimum of 3/4" 7 ply as well as meeting Leed requirements. Can you please confirm.<br /><br />Thank You

3/4" purebond plywood w/maple veneer Q# 2270 / Submitted 2/4/2009

Our 3/4" veneer core (VC) panels are typically manufactured with 7 layers (plies) of wood veneer, including 5 inner plies and a face and back. Inasmuch as we utilize our PureBond formaldehyde free adhesive system to bond these components, the resulting formaldehyde free panel product is LEED compliant. Additionally, we have the ability to provide FSC certified components if so specified. I would recommend that you contact your distributor representative and have them indicate on the order your need for LEED compliant material to ensure that all your expectations are met.<br /><br />Thank you for specifying Columbia Forest Products' PureBond formaldehyde free panels!<br /><br />Ang



I am an architect and I am working on a project where a historic building needs to end up as a Type IIIB (2007 CBC 602.3). 95% of the exterior walls are concrete but in the front is a historic facade that has plaster on the outside and the wall framing is exposed in the back. This wall needs to end up with a 0 hour fire rating, however it needs to be classified as ''non-combustible'' We want to propose to treat the wall framing in place with 'burn barrier' or something similar. The framing is too skinny to be 'heavy timber' mostly 2x8 and bigger and it cannot be removed to treat the face so the historic facade does not get damaged.<br /><br />Thank you for your answer,<br /><br /><br />W.

I have someone asking for appleply, does europly have all the same properties as appleply? <br /><br />I would need to prove to them that they are interchangeable. Can you help?

europly compared to appleply Q# 2268 / Submitted 1/26/2009

Appleply is a registered brand name of another hardwood plywood manufacturer. It was originally produced with all alder innerplies and intended to compete with what is typically referred to as Russian Birch or Polish Birch, except it is as "American as Apple Ply!" Currently, that product is sometimes interchanged with off-shore production, and probably is not produced with alder at this time. <br /><br />Europly is considered to be a sound veneer core product, intended for high end applications, suitable for the edges to be left exposed. While specific test results would produce varying results, Europly would be expected to have equal or higher physical properties. Our testing has produced results in the range of 9000 psi for MOR, 1,120,000 psi for MOE, and well over 500 lbs face screw withdrawal resistance. Of course, these results are not offered to infer the suitability of any other Europly panel, but more as a reference. You may want to conduct independent testing to determine if the product is suitable for your specific application. Hope this helps!<br /><br />Ang

white Oak -medullary rays Q# 2264 / Submitted 1/15/2009

Ray flake in white oak is unavoidable in any cut. In rotary and sliced woods, it typically isn't an eye catching characteristic, but in quarter sliced, and to a much lesser extent in rift cut, the flake will show due to the angle of the radial cut being more nearly parallel to the direction of medulation of the rays. The amount of "flake" thus developed is somewhat limited in the rift cut, but is pretty much unlimited in the quarter sliced faces. The only consideration that could make the flake unacceptable is if it is not soundly attached, but is instead separating or "feathering" away from the surface of the face. I will be happy to take a look at your photos, and will contact you separately for info on where to send them. Hope this helps!<br /><br />Ang



Is Columbia's 3/4 Maple Paint Grade Plywood manufactured with no added urea formaldehyde? Would this wood comply under LEED CI EQc4.4?

Maple Paint Grade Plywood Q# 2263 / Submitted 1/14/2009

"Paint grade" is a nebulous term not defined in any product standard, and therefore subject to unlimited interpretation. Assuming that in this context you are referencing an all veneer core (plywood core) panel with a medium to lower grade hard or soft maple face ( "C" or "D" as described in the ANSI/HPVA HP-1-2004 Standard for Hardwood and Decorative Plywood) and a medium to lower grade hard or soft maple back (#2 or #3 as described in the previously referenced standard), suitable to a degree for painting with appropriate surface preparation, then, yes, it would be manufactured with our PureBond formaldehyde free adhesive, and yes, it would be LEED compliant. You may also want to check with your Columbia provider relative to the availabilty of FSC certified material, which may also contribute to LEED compliance. Hope this helps!

My customer asked about using Tigerwood for his walk-in closet built-in. What is it and is it available in 3/4" veneer core or particle core 4'X8' sheets?

Tigerwood Q# 2259 / Submitted 12/31/2008

"Tigerwood" is a term that is very often loosely used to describe a particular figure pattern such as that encountered in highly figured maple ("tiger maple"), or natural appearance due to ray distribution such as in quarter sliced red or white oak ("tiger oak"). The term is also used as a trade name on occasion for a variety of species, most frequently for Astronium fraxinifolium, more commonly called Goncalo alves. If this is the case, this species is commonly used for tool handles due to its toughness, but it is avaialble on special order as veneer for decorative panels. It is dark to reddish brown in color with interlocked grain that may result in fancy figure patterns. The texture is smooth. The surface appearance is typically quite attractive. However, use as a closet liner seems like an unusual application for such a high value, attractive species. Typically, these applications are more suited to aromatic cedar, which is readily available in panel form and would not require special order. Hope this helps!<br /><br />Ang

Hi there: I'm about to have my flat roof re-done (in a wk or so) and the roofer will be replacing some of the older (perhaps rotted) plywood during the process of installing a modified bitumen roof. Would your plywood be suitable for that application? I note that your panels are not designed for outdoor use but not sure if this applies to roof boards? Thank you, Isabelle.

Roof plywood Q# 2257 / Submitted 12/28/2008

Thank you for your question, but our panels are just not designed for roofing applications. Conventional CDX 1/2" structural (spruce, pine, or fir) panels work exceptionally well in your application, as does OSB (oriented strand board) or so-called wafer board. The adhesive used in these products is phenolic formaldehyde, but it is extremely low emitting, and should not contribute to any health problem, especially in an exterior application. Thanks so much for your interest in our PureBond decorative panel products! We hope that when you have a need for decorative panels (like say, when you remodel your kitchen), you will specify PureBond panels for your cabinets! <br /><br />Ang<br />

Hi! I want to make a large, outdoor mosaic tabletop and am checking to see if you make formaldehyde-free plywood that I can use outside. If so, where in the New York metropolitan (Manhattan) area can I purchase it?<br />THANK YOU!!

Outdoor plywood Q# 2255 / Submitted 12/18/2008

I am sorry to disappoint you, but our panels are designed for decorative interior use. The adhesive in our veneer core panels is formaldehyde free, but while it is highly water resistant, it is not waterproof and therefore not recommended for exterior applications. Most exterior plywood panels are manufactured with a phenolic based adhesive which, while not technically formaldehyde free, emit at extremely low levels that they would be considered very safe for interior use. In an outdoor environment, the trace amounts of formaldehyde would be insignificant. Such panels are readily available at any big box home center. Hope this helps.<br /><br />Ang

What is the difference between Veneer Core and Classic Core plywood?

Veneer and Classic Core Q# 2252 / Submitted 12/11/2008

Veneer core is constructed with multiple layers of inner "plies" of wood veneers cut from species that are abundant but not as aesthetically pleasing as the face and/or back of the panel. It has the appearance of traditional plywood when viewed from the edge, and is sometimes preferred over engineered cores such as MDF or particleboard because it typically has greater physical properties. However, the surfaces adjacent to the face and back can be a little rough compared to the engineered cores. Classic Core bridges the gap between the two core types. All inner plies are veneer except for those directly adjacent to the face and back. Those plies are very thin layers of the smooth surfaced MDF. The appearance from the edge still is that of traditional veneer, but the surface of the substrate under the face is smoother. Hope this helps!<br /><br />Ang



We are currently doing a couple of LEEDs products were we're required to submit manufacturer's information that shows our composite wood products use urea formaldehyde free adhesives. We use Columbia Forest Products plywood, particleboard and MDF. You web site indicates that all mills have been converted over to the use of PureBond (formaldehyde free) in 2005 however the MSDS on this site still lists urea formaldehyde based adhesives. The MSDS was updated in early 2008, several years after the mills converted to PureBond. Is the MSDS still out of date? If not, where can I get an MSDS on your composite wood products made with PureBond?

PureBond adhesives vs urea formaldehyde adhesives Q# 2251 / Submitted 12/10/2008

Our 100% formaldehyde free panels are produced with veneer core and PureBond adhesives. While we do have access to both particleboard and mdf in a NAUF version, it is on a limited basis and by specification only. The MSDS for veneer core plywood PureBond plywood does indicate formaldehyde free, but the one for MDF and Partilceboard still shows emission limits for UF because we still must use available products manufactured with UF resins. The glue we use to bond the face and back to that core is formaldehyde free PureBond, but the composite panel still emits small amounts of formaldehyde. Hope this helps.<br /><br />Ang

What species of plywood is generally used when making alder cabinets?

plywood Q# 2249 / Submitted 12/8/2008

Plywood is a term that basically means any combination of components to include a face and back of a given species. In the case of alder, the face and back (if so specified) will consist of alder (Alnus rubra), and the inner veneer core plies will likely consisit of any number of species to include fir (Abies spp), yellow poplar (liriodendron tulipifera), aspen (Populus tremuloides), or pine (pinus spp). Alder faces and backs may also be applied over Medium Density Fiberboard (MDF) or Particle Board Core (PBC) if so specified. Any of these combinations are frequently specified by cabinet manufacturers depending on individual applications. Hope this helps!<br /><br />Ang



I am considering specifying VG fir faced or opaque finished appleply for a large high school project.<br /><br />How durable is it when we face applyply with veneer, rather than using the birch or maple face which the appleply comes with?

VG fir face appleply Q# 2248 / Submitted 12/6/2008

VG Fir is quarter sliced fir that produces a very fine and straight grain in douglas fir (pseudotsuga menziesii). The hardness of the species is similar to that of most softwoods, and thus is subject to denting and scratching if proper care and maintenance is not observed. It is, however, a highly prized and very attractive species and cut, and should serve well in your application. Finishing should include a wash coat or glue sizing to ensure a uniform finish, with trial finishes applied to scrap for suitability highly recommended.<br /><br />Appleply is a trade name for a veneer core product provided by a competing manufacturer, but our Europly or JayCore panels should more than meet your needs.<br /><br />Thank you so much for your interest in Columbia Forest Products!<br /><br />Ang

Let's say we order veneer core plywood from a vendor. We specify maple, A grade select white plain sliced fronts and 1 grade white rotary cut backs. Should the back BE rotary?

I apologize for the very lengthy delay in responding to your question, but due to a malfunction many questions to our site were directed incorrectly, and this oversite has only just now been discovered.<br /><br />The prevailing standard for hardwood is the American National Standard for Hardwood and Decorative Plywood, ANSI/HPVA HP-1-2004. Section 3.2 of the standard in the 4th paragraph reads "The species of industrial panel backs shall be the same as the faces for panels having grade 1,2,or 3 backs, unless otherwise designated." Section 3.4 Back Grades, states in sentence 7 (last sentence in the section): "Method of cut and matching may be different from that of the panel face unless agreed to between buyer and seller."<br /><br />While I understand your frustration, the above statements have been used liberally by the entire industry routinely for the entire 28 plus years I have been in it.

Pure Bond<br /><br />I have recently purchased your pure bond maple plywood with a clear finish on it. As this project specifies all Green materials I am OK with your adhesive but I need the certficate of compliance from you.

Certificates for Pure Bond and clear finish Q# 2197 / Submitted 8/25/2008

Our PureBond veneer core panels are manufactured with an adhesive that is definitely formaldehyde free. It is also possible to specify many of our panel offerings as FSC certified, another link in the green chain. As far as the finish, it is not a lacquer, but is a 100% solids ultra-violet cured coating that does not emit any Volatile Organic Compounds (VOCs). With respect to any certificate to that effect, the best suggestion I can make is to have you download our MSDS from our website. This document does not list any formaldehyde or VOCs for the PureBond panels, both of which must be reported if they occur above a very low threshhold amount. If you will provide your location, I will gladly have our specialist for your area contact you with any additional information you may need.

A question comes to me after 30 years in Interior finish business that I think I know the answer, but would like to check with an expert.<br /><br />When does "paneling" become an "Architectural Paneling"? <br /><br />My feeling is that anyone can go out and buy a hardwood plywood in Oak or Birch, but the materials commonly found in a big box retailer do not meet the grade requirements that are specified by the Architectural Woodwork Institute (AWI) which calls for Premium, Custom, and Economy - relating to the grades of AA, A, and B. It seems like the application - meaning the higher end applications - is when a product moves from "paneling" to "architectural paneling" or am I mistaken?<br /><br />I would appreciate your help in understanding this.<br /><br />Sam Beagle

When does plywood become architectural paneling? Q# 2191 / Submitted 8/13/2008

Architectural plywood is essentially any panel product intended for a high end application. Typically, the grade or custom specifications are provided by the architect, specifier, or designer, but even standard grades such as "AA" or "A" in most species would be considered applicable to architectural specifications. There are also architectural blue print panels which not only are specified by the architect, but also are produced to very specific sizes for very specific locations in accordance with an actual blue print. Hope this helps!<br /><br />Ang

wood floor underlayment Q# 2182 / Submitted 8/5/2008

Solid flooring with a UV Cured finish should provide a low to no VOC floor, and phenolic bonded underlayment will emit extremely such low levels of formaldehyde as to not be affected by most emission regulations. Our PureBond products are not recommended for flooring or sub-flooring, but are certainly desirable for decorative applications to include cabinetry, furniture, entertainment systems, and wall paneling. Hope this helps.



is your pure bond mdf formaldehyde free ?

mdf Q# 2181 / Submitted 8/5/2008

Currently, there are a few sources of No-Added Urea Formaldehyde MDF available to Columbia Forest Products in limited geographic regions. When combined with our exclusive PureBond® adhesive systems, the resulting panel is urea formaldehyde free. We are constantly on the lookout for and involved in research in the avaiability of formaldehyde free engineered products suitable for use as substrate components. However, the majority of MDF producers still use urea formaldehyde as a binder, so it will be necessary to specify PureBond® urea-formaldehyde free MDF core panels and inquire relative to availability at the same time to ensure your needs are met. Thank you so much for your interest in our PureBond formaldehyde free panel products!<br /><br />Ang

Why is it that you do not carry this product, I know briefly about the ethics issues, but can you site some sources, I have a customer asking.

Honduran Mahogany Q# 2179 / Submitted 8/4/2008

The Convention on International Trade in Endangered Species (CITES) became involved in the legal harvest, exportation and importation of Swietenia Macrophylla, commonly known as American Mahogany, Honduras Mahogany, and Bigleaf Mahogany as early as 1992. Due to the highly prized nature of the species for furniture and plywood, it has been heavily harvested as far back as the late 16th century. In the early part of the 20th century, harvest was taking a toll on the species to the point that in many areas only 2 - 3 mahogany trees per hectare could be harvested. Abuse of these restrictions led to management requirements that prohibit the harvest, exportation, or importation of the species without proper documentation to demonstrate that all legal channels were observed. CITES filed legal proceedings starting after the turn of this century to hold mahogany in any form at the ports of entry pending such legal documentation, and because almost without exception such documentation did not exist, American Mahogany became almost entirely inaccessible.<br /><br />Currently, there are a couple of importers who not only have access to a supply of American Mahogany, but some of it is even FSC certified. But...there is a caveat. This material does not come from the same regions as previous supplies, and not have the same consistent appearance of mahogany of the past. For that reason any job calling for the species should include a provision to obtain samples for approval by all parties prior to acceptance of any working agreement. The possibility exists for visits to a mill if the quantities are sufficiently large.<br /><br />Of course, African Mahogany (Khaya ivorensis) remains available, but even this species should be sampled for appearance prior to signing off on the final agreement.<br /><br />Hope this helps.<br /><br />Ang



hi there. if i've read your site correctly, you don't recommend using the Purebond plywood as a subfloor...is this correct? we have to replace a plywood subfloor for a client (it will be going onto wooden joists), and she is chemically sensitive, and looking for a formaldehyde free plywood. if your product won't work, can you recommend another that will suit our purposes?<br /><br />thanks,<br />tina

purebond plywood subfloor? Q# 2176 / Submitted 8/3/2008

You have read correctly. Our product is decorative and not structural in nature. Just as with any wood product, our panels obviously have structural properties, but because they are specifically designed for aesthetic applications we just don't recommend them for structural use. Most plywood sub-flooring is manufactured with phenolic resins that, while they do utilize formaldehyde in their formulation, emit only minute traces of formaldehyde gas. The emissions are so low, in fact, that they are below all current standard limits. I am sure you can check with any of the manufacturers to determine the suitabilty of their product for your clients needs. I wish I could be of more assistance.<br /><br />Ang



I purchased a piece of Oak 4x8 ply the other day at Home Depot in Falls Church, VA for $48.00 and noticed it was stamped with various manufacturing info including "PRISON". I am curious if you use prison labor in the process?

Prison Labor Q# 2175 / Submitted 8/3/2008

Without seeing the exact wording on the edge of your panel, I cannot be sure of what all the info means, but we do not use prison labor at any of our facilities anywhere. We do supply various state and federal penitentiary cabinet shops with plywood on a regular basis, but this is for consumption by those shops who do utilize prison labor under state and federal guidelines for the manufacture of goods for use primarily in their various systems. Why your panel has that designation is not at all clear. Wish I could be of more assistance.<br /><br />Ang

Hello Ang,<br />Trevor from Russell Plywood suggested I contact you and Jeff on a problem I'm having with color shifting on a dyed reconstituted wood veneer. The finished cabinets, especially on the side facing the windows, have strongly shifted from gray (originally) to an olive-y green. It is not a subtle shift. Some details:<br />The veneer is Tabu

color shifting in dyed reconstituted veneer Q# 2170 / Submitted 7/29/2008

David, I am familiar with the Tabu product, but haven't had a lot of exposure to it. However, I do know that some of the earlier dyes that were used to color many of the engineered veneers were susceptible to fading due to the effects of ultraviolet light. Subsequently, I checked around the internet and found one reference to that effect, http://modloft.com/ebay/veneer.htm, that supports that suspicion. I feel that the steps you reference in your question will definitely slow the process, but my suspicion is that they will not altogether eliminate the inevitable fading. <br /><br />I note that you referenced Jeff in your question, and he is actually the much more qualified person to address your concerns, so if you did not direct it to him as well, you may want to resubmit it under the Finishes section.<br /><br />Sorry I couldn't have been more help. <br /><br />Ang

I am wondering if your products are phenol formaldehyde free or just urea formaldehyde free is any additional formaldehyde in any form used in the manufacturing of your products

Hardwood Plywood Q# 2167 / Submitted 7/21/2008

We manufacture a formaldehyde free line of veneer core panel products utilizing our PureBond technology which has no added UF or PF. Columbia also assembles decorative hardwood plywood panels with MDF and particleboard cores which may be bonded internally with UF or non UF adhesives, including phenol formaldehyde and MDI. Increasingly, particleboard and MDF core manufacturers are turning to phenolic as the CARB rule approaches. To our knowledge, presently, there is no particleboard available that is bound with adhesives other than UF or PF. In certain geographic regions of the country MDF is available with an MDI binder. Check with your local Columbia distributor. Veneer core is easy: just ask for PureBond veneer core. For composites, however, excluding both PF and UF will eliminate PBC and leave only MDI bonded MDF core.



I need to replace the water damaged sub-floor in one of my upstairs bedrooms. I am looking for a tongue and groove 4x8 plywood product that is formaldehyde free and also free of other off gassing. Do you have such a product?<br />Thank you.<br />Anthony

Our PureBond formaldehyde free panel products are intended for interior decorative use, but are not recommended for use for underlayment or structural applications. However, the tongue and groove underlayment panels available on the market today are typically manufactured with a phenolic glue that emits so little formaldehyde that the resulting levels are far below any levels considered safe by the regulatory agencies, including EPA and HUD. <br /><br />Thank you so much for your interest in our PureBond formaldehyde free panel products.<br /><br />Ang



I want to use 1" russian ply for stair treads 10" by 40" suported only on the ends<br />possible?

russian birch plywood Q# 2164 / Submitted 7/19/2008

Stair tread span determination can be a tricky proposition. There really isn't a lot of readily available data on the subject, but the University of West Virginia (http://www.caf.wvu.edu/) has probably done as much work in this area as anyone if you would like to contact them. The only data I have on 1" material is for 9 ply, so the values will not likely be the same, but for a 48" span, an incremental load of 50 pounds resulted in a deflection of 3/4" with a maximum load determination of 165 pounds. For this reason the design you suggest may not produce the desired results. <br /><br />Ang

Purebond Plywood Q# 2163 / Submitted 7/18/2008

I apologize for the lengthy delay in responding. With respect to your need for fire retardant treated formaldehyde free plywood, our PureBond veneer core panels are available with a Class C (76-200 flame spread) only due to impracticality and lack of availability of suitable treatment methodology. Sierra Pine offers their Medite FR as a formaldehyde free MDF core that is available to us. This product consists of pre-treated fiber that means the treatment is all through the core rather than on the surface. As with any specialty product, there are always issues with minimum quantities, so it is doubtful that any of our distributors would carry exactly what you need. However, I would recommend you conduct a dealer search through our dealer locator on our site to find a dealer or distributor in your area to discuss your needs. <br /><br />Thank you so much for your interest in Columbia Forest Products!<br /><br />Ang

Our project in Washington State has a specification for Europly Plywood. The cut edges will be visible. However the project required all products to be No Added Urea Formadehyde. Does this product exist? Or is ther a substitution?

Europly-NAUF Q# 2153 / Submitted 7/9/2008

Europly is made primarily with a Urea Formaldehyde adhesive formulated to meet the E-1 European Standard, but it does not meet the requirements for NAUF. While it may be specified with a PVA adhesive, making it meet the criteria, that configuration would typically have longer lead times, be much more expensive, and bring with it fairly high minimum quantities. Alternate products may include Russian (Polish, Baltic) birch with their phenolic glue lines, but these products are not manufactured to the same appearance standards as Europly.

Purebond Q# 2152 / Submitted 7/9/2008

We have a formaldehyde free offering called PureBond. That product is manufactured using our proprietary formaldehyde free PureBond technology which we introduced in 2005, and all inner plies of hardwood or softwood veneers. We use the same technology to bond faces and backs to other no-added urea formaldehyde substrates as available, including NAUF particleboard and NAUF MDF. We also use the same adhesive to bond faces and backs to traditionally UF bonded particleboard and MDF, but these obviously can't be represented as formaldehyde free or no-added urea formaldehyde as the substrates themselves are still manufactured using UF glue.<br /><br />If you specifically need a formaldehyde free panel, please be sure to specify as much to your dealer or distributor to ensure your needs are met.<br /><br />Thank you so much for your interest in Columbia Forest Products PureBond offerings!<br /><br />Ang

quote infomation Q# 2150 / Submitted 7/9/2008

I am somewhat confused by your reference to a March quote. I do not find a question/answer on the site in March that would tie in to your question, either. If you are looking for an explanation of terms, WBP means water boil proof. E1 is a European standard for formaldehyde emissions, typically allowing no more than .13 ppm formaldehyde to ambient air in a test chamber. ACX is a grade designation of the American Plywood Association for structural plywood, and a panel so designated will have an "A" (high grade) face, a "C" (medium grade) back, and will be suitable for eXterior applications. C+/C+ sounds like a grading standard for European or Russian birch panels, and C+/C would be of the same origin. A-1 and A-4 are likely panel designations referencing the American National Standard for Hardwood and Decorative Plywood ANSI/HPVA HP-1-2004, which is the standard for North American decorative panel producers. Panels so designated will have an A (high grade) face and either a 1 (good grade) back or a 4 (very low grade) back, depending on specifications. Hope this helps.<br /><br />Ang

Why is this simple natural compound dangerous to one's health?

Formaldehyde Q# 2142 / Submitted 7/2/2008

Type in the word formaldehyde in a Google search and you will get over 6 and a half million entries. Formaldehyde, H2CO, CH20, CHOH, is one of the most common chemicals known to mankind. It is probably the single most common of all indoor air pollutants. It is also a necessary and important ingredient in many common household products to include building materials, cleaning supplies, paper products, and make up, to list a very few. It occurs naturally and is even produced in our own bodies as formic acid. The problem with formaldehyde is that it is a sensory irritant even at relatively low levels. That is, it causes respiratory response to include throat irritation, runny nose, and burning eyes. At higher levels of exposure these reactions become pronounced and very uncomfortable until the levels are reduced through ventilation or until the affected person or persons are removed to areas of lower levels. The concern is the long term cumulative effects may cause permanent damage to include hypersensitivity and upper respiratory damage. <br /><br />Formaldehyde is listed by the International Agency for Research on Cancer (IARC) and the US Environmental Protection Agency (EPA) as a known human carcinogen. Formaldehyde is regulated by OSHA as a potential cancer agent. The California Air Resources Board (CARB) has just instituted very stringent limitations on formaldehyde emissions from building materials and products shipped into California commensurate with that body



what brand cabinetry has ALL plywood construvtion Vs particleboard?

Many large scale national manufacturers and smaller local producers offer both plywood and particleboard carcass construction. Typically, particleboard is the major component in the cabinets produced by the larger companies due to its many beneficial features along with its economic attribute, but most also offer an all plywood construction as an upgrade.

No problem on the "not related to plywood" question! Four species come to mind right away: teak or ipe, both imported species available from many specialty lumber yards from responsible sources, and western cedar or reclaimed redwood. For the western cedar, try to find wood with as little sap (white colored) wood as possible as the heart (dark) wood is much more resistant to exterior conditions. Please understand that even these are susceptible to extreme conditions and are not immune to warp. However, they have traditionally proven suitable for such use. Best of luck!<br /><br />Ang

Purebond application Q# 2135 / Submitted 6/27/2008

Sorry for the delayed response, but I wanted input from our PureBond Team, and with the holidays that took longer than usual. Our stance is that we are currently developing adhesive products for several other types of composite panels, focusing primarily on MDF and PB. We have been approached by some curved plywood manufacturers and this is an industry we will be evaluating in the future. But, at this point we are working with those that are most affected by the new California emission regulations and are in need of new solutions in order to meet these requirements. Curved plywood is currently not a product that falls under the CARB regulations.<br /><br />In the meantime you may want to check the "Where to Buy" publication of the Hardwood Plywood and Veneer Association, Reston VA 703-435-2900 or www.hpva.org for curved plywood manufacturers, and check with them to determine if any of them utilize a formaldehyde free adhesive. There are certainly other such glues available, and I would be surprised if some of the curved manufacturers are not already using them.<br /><br />Again, please accept my apologies for such a delayed response.<br /><br />Thank you so much for your interest in our PureBond formaldehyde free products.<br /><br />Ang

Looking for 4 x 10 sheets of marine plywood.<br />Located in Austin, Tx.

4 x 10 marine plywood Q# 2132 / Submitted 6/25/2008

Marine grade plywood is a designation of the American Plywood Association covered in their product standard PS-1-95. Our industry does not produce this product under that proprietary designation, although the term is sometimes used generically to describe our panels made with water proof glue. Your best bet would be to conduct a search from our website dealer locator for dealers and distributors in your area with your inquiry. If you are a manufacturer requiring larger quantities, we would need to determine your exact needs.

I have some 3/4 cherry A1 Columbia veneer core P/S plywood. How do I tell the difference between the face and back sides? They both look very good.<br /><br />GPR

Face and back sides Q# 2131 / Submitted 6/24/2008

Typically, the easiest way to determine the difference is to check the relationship between each component (the narrow strips that are glued together side by side across the width of the surface) and the adjacent component on the panel. If there are sharp contrasts at the point where the components come together, you are looking at the back. If two side by side components appear to create a mirror image at that point, you are looking at the face. Usually, the back has more natural characteristics than the face, to include more small knots and color variation from very light colored sapwood to a darker reddish brown heartwood. Hope this helps! Thank you so much for a great question.<br /><br />Ang

Would you please answer the following questions?<br />Do you use phenol formaldehyde?<br />If so what is the level of concentration?<br />And, which products?<br /><br />Also, what is the level of concentration, parts per million, <br />in your products with eurea-formaldehyde?

types of formaldehyde Q# 2129 / Submitted 6/23/2008

We do occasionally use phenolic formaldehyde adhesive in a couple of our mills for specialty applications. The emission levels are so low as to be considered below the de minimus levels required for reporting. Our urea formaldehyde products meet or emit lower than the requirements of the HUD 3280 and the ANSI/HPVA HP-1-2004 standards, which is 0.3 parts per million for Industrial Stock Panels. As you know, our PureBond adhesive is formaldehyde free.<br /><br />Thank you so much for your interest in Columbia Forest Products.<br /><br />Ang

I am looking for something like the Europly which is formaldehyde free. do you have such a product? <br />Also, do you make formaldehyde free mdf?<br />thank you

Formaldehyde free Q# 2126 / Submitted 6/17/2008

Our Europly is produced to meet the current E-1 European standard for formaldehyde emissions, but is not considered formadehyde free. The product is designed to provide a pleasing edge appearance that can be left exposed. Because of this, a U-F resin is used. On the other hand, Russian birch is a multi-ply product that utilizes a phenolic adhesive that is below the de minimus levels of emissions, but it has a dark appearance and is not as suitable for edge exposure. <br /><br />We do have a no-added urea formaldehyde MDF core available. <br /> <br />If you would be so kind as to provide your location, I will be happy to have our specialist in your area contact you to discuss your needs further.<br /><br />Thanks you so much for your interest in Columbia Forest Products.<br /><br />Ang



I'm looking for to find the buckling (compression strenght on edge) resistance of a 3/4'' birch plywood. It was used to build a bar on witch 5 people should be able to dance. We want to validate the structure. The pieces are 18'' high. I know you gave some values regarding 1/4'' sheets but I would need the 3/4'' engineering values. If you have them all (tensile strength, axial compression, shear etc.) that would help too! Thank you very much

Buckling strenght of 3/4'' birch plywood Q# 2125 / Submitted 6/17/2008

Our product is manufactured as a decorative panel for use in cabinet and furniture manufacturing, and is not typically sold for its structural properties, and would not be recommended as a standard flooring or weight bearing surfaces. The properties you request can vary greatly depending on construction and species, and thus it would be difficult to provide the requested specs for your specific products. Additionally, the construction design of the bar would be as important or more so than the properties of the plywood. You may want to contact the US Department of Agriculture Forest Products Laboratory in Madison WI (USA). They do have the ability to provide some physical properties depending on the specifics. You may reach them at 608-231-9200. <br /><br />Ang



We are looking into using UF-free perforated plywood panels as a finished surface in a production area of a winery. Is pure bond plywood suitable for very damp (wet) locations? The literature only says "Approaching... waterproof performance"

Pure Bond in wet locations Q# 2124 / Submitted 6/16/2008

Our products are manufactured as decorative panels suitable for use in kitchen cabinets, office furniture, and similar applications. I have seen our product used successfully in many other types of applications, but unfortunately cannot guarantee the suitability of the product for your specific application. The adhesive is rated Type II (water resistant) in accordance with requirements of product standard ANSI/HPVA HP-1-2004, and is not considered an "exterior" product. It is formaldehyde free. If you would like to provide your location, I will be happy to have our specialist in your area contact you.<br /><br />Thanks so much for your interest in Columbia Forest Products.<br /><br />Ang



I am looking for products rated to the equivalent of BS1088 utilized my Lloyds for marine purposes. What products do you have that meet the marine standard. The ply must have no core voids, no face patches, and use water and boil proof glue.

Marine Plywood Q# 2123 / Submitted 6/13/2008

We do not manufacture a panel to either APA Marine Grade or the BS1088 standard to which you refer. Both cover panels not necessarily intended for decorative applications in a marine application, and the adhesive must be water and boil proof as you indicate. We do manufacture a Technical Type in accordance with our industry standard, ANSI/HPVA HP-1-2004. Such panels require a water proof adhesive that will pass the Cyclic-Boil Test outlined in Section 4.4 of the standard and the Two-Cycle Boil Test as outlined in Section 4.5. The inner plies adjacent to the face may have small splits up to 1/8" wide, and other inner ply components may have open knot holes up to 3/8" in diameter and splits up to 1/4". Our faces are typically decorative hardwood and softwood species not typically patched in the same manner as Marine Grade plywood. Your best bet will be to conduct a dealer search using our dealer locator, and contact a dealer or distributor to discuss your specific application and needs.<br /><br />Thank you so much for your interest in Columbia Forest Products!<br /><br />Ang



I have a guy who wants 1000 cubic meters of 1/4" 4x8 plywood. How do I figure out how many sheets that is?

how many sheets Q# 2121 / Submitted 6/12/2008

This should be a reasonably simple mathematical process, but I never claimed to be good at math. If I calculate correctly, assuming an average thickness of 5.2 mm, approximate width of 1220 mm, and length of 2440 mm, there are approximately 0.0155 cubic meters in a single panel. Divide one cubic meter by 0.0155 and you get approximately 64.5 panels, meaning 1000 cubic meters would equate to 64,000 to 65,000 total panels. You might want to double check my math. Thanks for a great question!<br /><br />Ang



I've always been against using lumber for drawer fronts when applied to a four-sided drawer box. There are companies that do this regularly, though. Besides the likely different stain/finish appearance vs veneered doors, it would seem these drawers would also be prone to cupping/warping and splitting. Yet these other companies do it regularly into the school casework market. Am I wrong?

lumber drawer fronts Q# 2119 / Submitted 6/12/2008

Most of the producers who use solid drawer fronts are using narrow strips edge jointed and with reverse ring orientation for every other component to offset stress. They are also using uniformly dried material to achieve the highest stability possible. Drawer front joints are generally allowed to completely dry prior to planing and profiling to avoid problems associated with shrinking after planing. Typically, the drawer front is attached to the face side of the inside front of the drawer carcass in a manner that allows for those rare occasions when they need to be replaced. As for finish similarity, I just haven't seen any real problems as long as one understands that wood color will vary even when finished in the same manner, regardless of whether it is in veneer form or solid form. From what I have observed over 28 years, this practice is not only common, but it also makes for a very attractive drawer front. Hope this helps!<br /><br />Ang



Do you have engineering values for quarter inch birch or maple plywood? We have designed a ceiling using 200 panels of one quarter inch plywood, which is only serving a visual purpose. We have smoke development data, but now the building department is requesting MOE and bending allowable specifications. Can you please help us with this info, even if it's a range?

engineering specifications for birch or maple plywood Q# 2118 / Submitted 6/11/2008

I apologize for the delayed response, but I have been trying to find the data you seek without much success since you submitted your question. The biggest issue is that for the most part 1/4" panels are not sold for their physical properties, but rather, as in your application, for decorative purposes with the framework making up the engineering aspect of the project. For that reason, manufacturers just don't have that data typically at their fingertips. Even thicker decorative plywood panels are manufactured for their aesthetic value rather than their engineering function, but there is some, albeit limited data on 1/2" and 3/4". I did locate a very old list of data from some testing that was done over 40 years ago for the aircraft industry, and 1/4" birch (betula spp.) with a yellow poplar (Liriodendron tulipifera) inner ply veneer core is included in the list showing MOE (modulus of elasticity) of 1,140,000 psi parallel to the face grain direction, and 300,000 psi perpendicular to the face grain direction. Additionally, there is a column labled "Stress in Outer Fiber Bending" that lists values for the above referenced product of 1,400 psi parallel to the face grain and 750 psi perpendicular to the face grain. It is important to note that these values are mathematically calculated estimates based on a complex formula for the specific species listed, and all MOE, MOR, Stress, and other physical property values are subject to vary, sometimes significantly, from species to species, and, when physically tested rather than mathematically calculated, even within a given species and / or combination of species and thicknesses. In other words, the values shown above cannot be considered as directly applicable to your panels, and actual results could vary greatly.<br /><br />I sure hope this helps!<br /><br />Ang

I am building several cabinets all over the house (kitchen, bath, family room, closets, and so on). All of them will be painted an off-white. Someone told me Birch plywood would be a waste of money and I should go with shop-grade maple. What is the appropriate plywood grade to use for painted cabinets? Thanks!

Plywood grade suitable for paitned cabinets Q# 2115 / Submitted 6/5/2008

This is a common question among dealers and distributors, in addition to cabinet shops and home owner/DIYers. Just about every one has an opinion on the answer, but there is no truly right or wrong answer. For some, very low grade birch or maple constitute paint grade, but my problem with that is the lower grades allow knots, bark pockets, and splits that show up more after they are painted. I would suggest a higher grade, preferrably "B" sap maple or "B" sap birch, which ever is avaialble in your area, as either is very paintable and relatively free of any distracting surface features. Sand the surfaces first with a high quality 220 grit or finer sand paper , then prime with a high grade primer. Lightly sand after priming with a 220 grit paper and your paint job should be the envy of the neighborhood.<br /><br />"Shop" grade means only that the panel in question was a factory second due to some type of defect that developed as a result of fabrication. Shop panels are generally a good deal, but you can't specify the grade. Bite the bullet, spend a little more, and rave over the job for years! Amortize the little additional cost over the life of the cabinets and you will find the difference is negligible!<br /><br />Thanks for a great question!<br /><br />Ang



What is the MOE for Columbia's standard veneer core plywood 5/8 and 3/4?

MOE for Standard VC plywood Q# 2113 / Submitted 6/4/2008

This isn't an easy answer question for a number of reasons. First of all, we manufacture veneer core products in mills all over the US and Canada using indigenous species that vary significantly in physical properties from one region to another, and to some extent even within a given geographic location. Additionally, we purchase other species from all over the globe in raw veneer to pre-assembled core platforms in a number of combinations. Add to that the fact that our product is manufactured for its aesthetic applications much more so than for its engineering properties to the extent that our industry isn't required to keep running test records of physical properties. We do obviously have results from occasional testing conducted at one time or another on all of our more common constructions, but to give you a single answer would be imprudent as the number would be specific only to the specimen from which it was measured.<br /><br />Having said that, Modulus of Elasticity (MOE), is a value assigned to the resilient elastic behavior of wood relative to applied stress. Testing we have conducted indicates values ranging from 350,000 psi for some imported species to as much as 1,000,000 psi for some domestic species, with numbers ranging between these two extremes for other species, domestic and imported.<br /><br />Hope this helps at least a little!<br /><br />Ang<br /><br />

Exterior Cypress plywood Q# 2109 / Submitted 5/29/2008

Steve, the biggest issue is that a decorative plywood panel just isn't recommended for exterior applications. However, such use is common with certain constructions and species in applications as you have described. If the adhesive used is water proof, and the panel is thoroughly sealed on all surfaces, it may be used with the understanding that any adverse effect from exterior exposure that shortens the service life of the panel is out of the control of the panel manufacturer and therefore not a warantable condition. One other caveat is that baldcypress (Taxodium distichum) is often purported to be weather and insect proof, when in actuality only the heartwood of the species is relatively resistant to decay and insects. The sapwood is no more resistant than that of other species. <br /><br />Hope this helps! Thanks for a great question!<br /><br />Ang

Hi,<br /><br />I am making many plywood paint palettes. The will be rectangular and painted with white emulsion. They have cut out handles at either end. They will be roughly 1.5ft by 10" wide. I will stick pieces of painted paper to them and they need to last for a long time- up to 5yrs. They will be kept in dry conditions. Is there a danger the plywood (6mm) will warp over time, and if so, how can I prevent this??<br />Many thanks,<br /><br />Jemma

(6mm) plywood warping? Q# 2105 / Submitted 5/23/2008

Any wood product is subject to dimensional change that will result in warp or distortion from a flat plane, depending on conditions. For best results, allow the panels to acclimate to their surroundings before fabricating them into the rough size before making the cut-outs. Once all final cut-outs and edge machining is complete, again allow the finished parts to acclimate. During the acclimatization periods, the parts should be stacked uniformly together on a flat surface and weighted down for at least 2 days before proceeding to the next step. If warp is evident during any fabrication stage, try turning over every other component during the stacking process before allowing the components to acclimate. After that, all surfaces and edges should be painted with the same number of coats. If you apply decorative paper to one side, you should consider applying a balancing component to the other, preferrably the same type material. In service conditions should be 65-75 degrees F and 30-60% relative humidity.<br /><br />Even with all the measures listed above, a multiple ply veneer core plywood component can not be guaranteed for suitability for any use, and yours is a demanding one. Taking the above precautions will go a long way towards minimizing those factors that contribute most to warp, but unfortunately, no procedure can totally eliminate the potential to warp.<br /><br />Thanks for a great question.<br /><br />Ang

does exterior plywood come in 1-1/8" thickness?

exterior plywood Q# 2103 / Submitted 5/21/2008

I don't know of any manufacturer who produces 1 1/8" as a stock item, whether decorative plywood made with a waterproof glue, or structural plywood designed for exterior use. Typical sizes found at most dealers and home centers is 1/4", 1/2", and 3/4" for decorative plywood, and 15/32" and 23/32" for structural. Most manufacturers can produce 1 1/8" thickness, but this would usually require a special order with minimum quantities for structural, or substantial pricing with extended lead times for small quantities of decorative panels. <br /><br />Ang



I'm considering proposing new, more cost-effective cabinet construction for large project owners. Are lumber core or combination core cost effective vs veneer or particleboard cores? Are there more cost effective but acceptable-appearing veneers vs traditional oak and maple?

Our Classic Core combination core is a very acceptable alternative to veneer core, and it is available as a urea formaldehyde free product. Lumber core of any reasonable quality is typically quite expensive. The lower cost lumber core options are generally not recommended due to quality concerns. For very acceptable appearing veneer options, our Appalachian Traditions line of birch, oak, hickory, and maple offer a unique appearance in species that are avaialble as FSC certified. <br /><br />Hope this helps!<br /><br />Ang



Do you have a suggestion for the type of lighting that we should use to inspect unfinished plywood panels for defects. The thing the we miss the most would be knife marks in white maple.

Inspection lights Q# 2101 / Submitted 5/16/2008

There are a number of options for lighting, all of which should be mounted on adjustable frames so that they can be set to the height of the inspection surface. Halogen, standard incandescent, and natural light are generally the best.

why does plywood warp?<br />How to keep plywood from warping?

Warping plywood Q# 2096 / Submitted 5/13/2008

Unfortunately, this isn't a short answer question. Plywood warpage is a result of imbalances in the panel caused by a wide variety of contributors, including:<br />different species and/or cut face and back, a different treatment or finish on one side than the other, no finish on one side with a finish on the other, extremes of humidity and temperature in the fabrication areas or in service locations, natural or inherrent physical property differences, high or low moisture content of the panels, inadequate time for panels to acclimate to their environment, installation of panels or furniture or cabinets etc prior to activation of HVAC, and a host of others. For best results, panels should be allowed to acclimate prior to fabrication. Any treatment on one side should be applied to the other. Avoid extreme temperature and humidity conditions with 65-75 degrees F and 25-55% Rh being preferred. Keep panels neatly stacked in humidity controlled environemnt with runners (stickers) uniformly alligned and with a cover sheet on the top of opened units. <br /><br />There is an abundance of information published about panel movement by the US Forest Products Labratory, the Hardwood Plywood and Veneer Association, numerous university wood science schools, and I even cover the topic in my book, A Complete Guide to Hardwood Plywood and Face Veneers, available from HPVA. <br /><br />Thank you for a great question!<br /><br />Ang

t-111 Q# 2094 / Submitted 5/7/2008

T-111 is a product of various softwood plywood manufacturers, routinely sold in most large home centers in 3/8" and 5/8". Groove patterns may vary between manufacturers, so you may have to check with more than one to ensure you have a match. The age of the existing job shouldn't be too much of a factor, as most manufacturers don't routinely change patterns too often. If you have difficulty locating your pattern, you may want to contact the American Plywood Association at apawood.org.

The only soak test we are required to perform measures the quality of our glue bonds.<br /><br />Hardwood and decorative panel products are produced from technically dry components (6-12% mc) and are normally less than 12% total mc at time of shipment and therefore considered to be dimensionally stable. However, panel manufacturers cannot control fabrication or in-service conditions of products produced from hardwood plywood panels, and these conditions vary greatly depending on geographic region and the type of internal climate controls in the fabrication facility or home or commercial location. For this reason, there are numerous references from various sources with which any fabricator of decorative wood components should become familiar to avoid problems associated with dimensional change. The Hardwood Plywood and Veneer Association (hpva.org, 703-435-2900) in Reston VA is one source for such information, as is the US Forest Products Laboratory in Madison WI, and the Architectural Woodworkers Association (awinet.org, 703-733-0600, also in Reston VA. Essentially, these associations recommend interior conditions of 25-55% at 65-75 degrees F for best results and minimum movement of otherwise dimensionally stable wood products.<br /><br />Hope this helps.<br /><br />Ang



I have a customer that uses your Okoume marine grade plywood to manufacture decorative cupolas for exterior rooftops. They have had problems with their paint system and the result is that many of their installations are rotting prematurely. All surfaces are coated inside and out before assembly, so I am diligently trying to determine where the moisture is intruding. They are using an acrylic latex primer and topcoating with a high gloss alkyd. When they used an all alkyd primer and topcoat the problems did not manifest, but they switched to latex primer to accomodate the painter (vapour was bothering the painter). The sample provided to me is five ply marine grade Okoume from Columbia (according to the customer, there are no stamps or markers on the wood I received).<br />What type of glue is used to bond the product layers? I think the ends of the boards could be where the moisture is getting in and wicking to the entire structure. <br />How would your company recommend that this board be painted for exterior use?<br /><br />Regards, <br />Glenn Poirier<br />Commercial Development Representative<br />Benjamin Moore Paints<br />Toronto, On<br />416-428-6457

Pint recommendations for exterior grader Okoume plywood Q# 2088 / Submitted 4/29/2008

There are several concerns here. First, let's clear up a common misconception: Columbia Forest Products does not produce a "Marine Grade" plywood panel. Marine Grade is a designation of the APA (apawood.org)Grading Standard PS-1-07, which describes the requirements of an all softwood construction grade panel product designed to strict manufacturing requirements to stand up to the rigorous conditions of marine applications. Even then, these products are typically encapsulated in fiberglass to prevent moisture penetration. Our panel products are manufactured to the requirements of the HPVA (hpva.org) product standard ANSI/HPVA HP-1-2004 for hardwood and decorative interior use panels. Even though our standard has a provision for a Type I and a Technical Type panel produced with a water proof adhesive for elevated moisture indoor applications, this product is not impervious to water damage and thus not suitable for exterior use. Typically, when a Type I adhesive is specified, it is either a full melamine formaldehyde or melamine fortified urea formaldehyde system, both very common and time proven performers in high moisture conditions. Neither render the wood itself water proof. Only the adhesive is waterproof, meaning the glue won't fail in high moisture conditions. The wood is still subject to all reactions to water over time: dimensional change (swelling/warp), mold, and, of course, decay (rot).<br /><br />While I obviously cannot say whether we manufactured the product in question, we have the capacity to produce or import a panel with okoume (Aucoumea klaineana) as a face and back species, although it is possible but unlikely that the inner plies are okoume. Even so, this product should not ever be considered as an exterior use structural panel. <br /><br />You are likely right that the end grain of the panel components are wicking moisture from both the water based latex and precipitation exposure, but that would not be uncommon even if a true marine grade were used. The prior process utilizing the alkyd primer may have been more effective at prolonging, or even preventing premature rot, but I personally would still just not recommend the product you describe for this application. <br /><br />My advice would be to have your customer consider using a true APA designated marine grade product for this application, but before they make the switch, I would advise them to contact the American Plywood - Engineered Wood Association (apawood.org) or one of their member manufacturers for recommendations on waterproofing for external applications.<br /><br />Hope this helps!<br /><br />Ang

I purchased 12 sheets Columbia birch plywood 3/4".

Can I still find Columbia product to match original? Can you help. I built 2' x 112' table and need to fill two sections with SAME PRODUCT.

Birch Plywood Q# 2076 / Submitted 4/21/2008

Unfortunately, a veneer core product will have variation in thickness due to the many natural and manufacturing variables associated with a composed wood product. That is why the industry standard for hardwood plywood allows a range of thickness of 0.047" (3/63") below the nominal thickness for a given construction. In consideration of the foregoing, no one can guarantee that their product will be an exact thickness match to panels you purchased some time in the past, but no 3/4" panel should vary more than the standard allowance of plus 0, minus 3/64". Most production will be much closer than that. I apologize that I could not be of more assistance.<br /><br />Ang

Water damage to a columbia laminate floor has caused noticable buckeling at a seam in the floor. Is there any thing we can try short of replacement to minimize the appearance of the buckle? Treatment with heat, heavy weight and time? If replacement is necessary, can the finish be matched, the floor is about 6-7 years old but in perfect condition other than the buckle. At the time of install we were told that replacement of select boards was nearly imposible because of the tonge and groove install design. Is this true or do we need to find a more qualified technition. Any suggestions would be appreciated. Thanks

I am currently restoring a 1940's modernist home which has an interior almost entirely clad in 6mm ply panneling. I have managed to solve the refinishing problem by adding oxides to shellac for colour matching the patina but have run into problems in some areas that have moisture dammage- bulging and cupping of the pannels. I assume that this happened because of moisture in the wall cavity causing the wood fibres to expand and having no where else to go the pannels buldged outwards. If anybody knows if there is a method for minimising or reversing this cupping/bulging without having to replace the pannels i would be very interested. Perhaps there is a way to encourage the wood fibres to contract??<br /><br />Thanks,<br /><br />Gidon Bing

Interoir plywood cladding restoration. Q# 2067 / Submitted 4/11/2008

If you have a moisture source in your wall cavities, this must be addressed first before any wood paneling product applied to that wall will ever serve you well. It is very likely that the side adjacent to the framing could take on more moisture than the side facing the room, thus resulting in the buckling. Unfortunately, while resolving the moisture problem may allow the wood to stabalize somewhat, there can be no guarantee that the paneling will ever return to its original flat state. <br /><br />For future reference, it would be highly advisable to ensure there is no moisture source within the wall framing prior to installation. Additionally, application of dry wall prior to installation of thin wall paneling is advisable. The drywall should be patched, allowed to completely dry, and sealed with a primer prior to installation of the paneling. Paneling should be allowed to acclimate to the room where they will be installed for at least 48 hours prior to installation. Finally, the unexposed side of the paneling should be sealed to allow both sides of the panel to resist moisture movement in the same manner, thus minimizing the possibility of a moisture embalance which likely contributed to your current problem. <br /><br />I am sorry I couldn't be of more assistance.<br /><br />Ang

We purchase our plywood through home depot and are consistantly having problems with the veneer de-laminating.

The location of the home depot where we purchase the plywood is in the laval/montreal quebec area. We spend a lot of time repairing and/or re-glueing the plywood. We like the product but are loosing confidence in the adhesion between the hardwood veneer and the plywood substrate .

birch and maple veneer plywood Q# 2064 / Submitted 4/5/2008

I am sorry to hear about the experiences you are having with our plywood purchased from The Home Depot. As a manufacturer of hardwood and decorative softwood plywood, we place a tremendous amount of emphasis on producing a high quality serviceable glue bond between all components in our panel, and in that light we have highly refined adhesive application and pressing protocols in place. However, due to the high number of variables in our process, there are times when the glue just does not properly bond, and the result is what you are experiencing. I won't bore you with all the various contributors to delamination, but regardless of the cause, it creates a hardship on not only you as the end user, but also on everyone in the supply chain. I hope you are taking your complaint back to the center where you purchased the plywood, and would encourage the panel products manager to contact us directly or through their established channels so that we may address the issue for you in an appropriate manner. We thank you for your patience and for reporting this condition to us.<br /><br />Ang

Can classic core be used for cabinet doors were bowing and cupping is a cocern? Does it stay relatively flat?

classic core plywood Q# 2061 / Submitted 4/1/2008

As with any plywood product, balance is the key to flatness. Starting with specs, the face and back should be of the same species. From that point it is up to the producer to ensure that the inner components are assembeld in a balanced fashion. If all works well, any such panel should remain relatively flat, and ClassicCore is certainly as suitable for cabinet doors as any all veneer core panel.

years ago the hardwood plywood industry used glitter in ther plywoods to tell the differences from one factory from another. Do they still do that?

glitter in plywood Q# 2060 / Submitted 3/31/2008

The use of ordinary decorative metallic glitter of proprietary colors has long been and continues to be practiced in the decorative plywood trade in North America as a simple but accurate means of identifying a given manufacturer's product from that of a competitor when such need arises. Many manufacturers can identify their product if they use a unique veneer core construction in cases where that particular company or mill has access to species used as inner plies that are indiginous to their given geographic area, but many use common species such as spruce, pine, fir, poplar, or aspen, so the glitter may be the only way to legitimately know. Additionally, when the substrate is an engineered board such as MDF or particleboard, the identifier is the only sure way to know. I believe the Hardwood Plywood and Veneer Association in Reston VA at one time maintained a list for its members that may still be available if you wish to check further.

What is the difference between Walnut and Black Walnut? Is there such a thing as Fumed Oak, and is it similar to Walnut?

Walnut Plywood Q# 2055 / Submitted 3/25/2008

Walnut and American Black Walnut are trade and common names for the species Juglans nigra, and these terms are interchanged indiscriminately. I am not familiar with "fumed" oak, but the term is probably a reference to the heating of the log in preparation for peeling or slicing, which can cause color changes in the wood. It would be a strecth to call any oak (Quercus spp.) similar to walnut, as oak is a ring porous wood with an abundance of open (porous) grain in the early growth regions, and walnut is a semi-ring porous wood with only a slight amount of open grain in the small early growth areas. Typically, both red and white oak are a lighter color than walnut heartwood, ranging from a light grey to light pink to light browns with reddish hues, while walnut will normally have a dark brown coloration, depending on the process.

I have an "interpretation " issue on a project <br /> <br />can I find information on what is <br />"book match " " blueprint match " and "end match "??<br />somewhere on your website perhaps ?

wood veneer finishes/ definitions , Q# 2047 / Submitted 3/14/2008

There is an abundance of resources in print and electronic form that define and even show illustrations of the terms you mention. This website, http://www.oakwoodveneer.com , shows book, slip, and random matching, and this one, http://www.mbveneer.com/index.html, has a slide show that shows book and butt matching that is very similar to end matching. Book matching refers to the side by side relationships of any 2 components in a spliced face. To accomplish a book match, every other component is turned over and jointed to the edge of the adjacent component in such manner that there is a mirror image of one component to the other at the splice joint. End matching takes this to another level so that not only is every other piece in a given sheet turned over, every other sheet of resulting veneer can be flipped upside down and butted to the top of the adjacent sheet in such way that the end-to-end stacked panels create a mirror image of the grain pattern at the point where the two meet. Architectural blue print matching means that the panels are actually constructed with a veneer usually pre-approved by an architect to the exact specifications of the architect to be applied to the job at the precise location indicated on the blue prints. The panels will be numbered on the print, and can vary in size to accommodate the length and height of the walls, and to fit around pilasters, windows, doors, and other protrusions, and may include veneers that are cut in such manner that, for example, the bottom portion of the face becomes a door skin and the top portion of the same veneer sheet becomes the transom above the door. Confusing, I know, but I hope this helps a little. Thank you so much for your interest in Columbia Forest Products!<br /><br />Ang<br />



Is it normal for your 3/4 "plywood to warp and have so many defects in the veneer?<br />What I am trying to say is that warping and numerous defects in the veneer turned my project into a nightmare. Any thoughts on this?

oak plywood Q# 2046 / Submitted 3/14/2008

It is always disappointing to learn that anyone has encountered a problem with a decorative panel from any provider, so let me begin with an apology that you have had such a bad experience. <br /><br />A little movement, generically referred to as warp, is normal in any wood product, and is influenced in most cases by the environment or the conditions in fabrication and in service. Normal fluctuations of temperature and relative humidity will allow the wood to give off or take on moisture through a process called hydrogen bonding, and the result will be that because of the uneven stresses that are created, the part will "move." Most of the time, this movement is barely detectable and does not affect performance.<br /><br />In some extreme cases, warp can be built into a panel due to the extreme number of variables involved in processing wood from the log to a furniture component. These factors include moisture content differences between combined components, natural variation of physical properties in the wood itself, uneven adhesive application, and on and on. Although uncommon to the extent you have experienced, this certainly can happen, and the end result is a bad taste for a given producer's product. <br /><br />It sounds from your question like you have finished your project and were able to effectively force the panel to work, but please be assured that this is not usually the case with a properly constructed panel fabricated into a furniture or cabinet project under prescribed conditions of temperature (68-75 degrees F) and relative humidity (30-60%).<br /><br />Again, I am so sorry you experienced so many problems. Should you have further questions or concerns, please feel free to contact us again.<br /><br />Thank you so much for your question.<br /><br />Ang



My friend built a house in 1960 and the architect and builder (separate people) put redwood plywood on the exterior. Now in 2008 it is still fine. We live in central illinois. Why don't these products exist now? Thanks

exterior plywood Q# 2043 / Submitted 3/8/2008

Redwood is one of the most naturally weather and insect resistant woods known, and it is no surprise your friend's exterior has held up so well. Unfortunately for the building trade, but fortunately for the species (Sequoia sempervirens), it is listed as a threatened species due to the fact that over logging and poor management practices have reduced the once abundant stands to around 50% of their original volume, and because of their limited range, which is restricted mainly to northern California. There is still some redwood harvested, but availability is severely limited compared to what it once was. Fortunately, today's forest management practices are far more environmentally responsible than they were in those days. Thank you for a great question!<br /><br />Ang

Are any of your products useful for building sliding closet doors that will measure 9'x30"x1.25" with glass panels? Will this weight be to much for the screws supporting the upper rollers? Further I want a maple veneer finish.

Sliding closet doors Q# 2034 / Submitted 2/27/2008

While I am always eager to promote our decorative panel products, your application seems more suited to solid dimension lumber. Our veneer core products have excellent screw holding properties, generally in the 250-300 psi range, and that could be sufficient for your upper rollers, but generally speaking, solid lumber is more suited for use as stiles and rails for glass panel doors of just about any design. Thank you so much for your interest in Columbia Forest Products!<br /><br />Ang



I have been told that WBP means:<br /><br />Water Boil Proof<br /><br />Weather Boil Proof<br /><br />Water Based Phenolic<br /><br />And although all of these are to describe what I think is an Exterior glue, I was wondering if you could point me to a reference material that says what the proper description of WBP happens to be?<br /><br />Thanks,<br /><br />Sam Beagle

What does WBP really mean? Q# 2033 / Submitted 2/26/2008

I had to do a little digging for this one as it is not a term used in the decorative panel industry. My friends at the APA/Engineered Wood Association (apawood.org)were able to quickly reference a British Standard 6566, Part 8 under the topic of Bond Performance, and it seems the term means Weather and Boil Proof. So, your presumption that it refers to an exterior glue is right on point. We didn't have the exact name of the standard, but it is developed by the British Standards Institute in London. Hope this helps!<br /><br />Ang



I need to replace the subflooring in the upstairs of my home. The old 4X8 sheets of plywood that served as the subfloor were water damaged. I am looking for a 4X8 tonge and groove product that is formaldehyde free to use as my subfloor replacement. Do you have any such product?<br /><br />Thank you,<br />Anthony Scolaro

sub flooring Q# 2031 / Submitted 2/25/2008

Tongue and grooved subflooring panels are typically manufactured with a phenolic adhesive system that while not technically formaldehyde free, emit such low levels of formaldehyde that they are considered safe for indoor installations. Additionally, while such plywood products are not completely impervious to water damage, the adhesive used in them is water proof. Our PureBond panels are manufactured as an aesthetic product with a highly water resistant adhesive, but they are just not recommended for structural applications such as subflooring. Thank you so much for your interest in our PureBond formaldehyde free products! Should you have a need to replace your kitchen or bathroom cabinets, we hope you will request that the cabinet maker specify PureBond! <br /><br />Ang



Materials Safety Data Sheet <br /><br />for your prefinished hardwood plywood. is it on your site?

pre-finished maple plywood? Q# 2030 / Submitted 2/25/2008

It is included in our UF product MSDS, (See Our Product Line, right side of the page) but not yet on the NAUF sheet. It is listed in the product names as UV Wood, but because the UV cured finish is VOC free, there are no hazardous compounds to list on the MSDS. Although the NAUF MSDS does not list UV Wood, this applies to those products as well. Thank you so much for your interest in Columbia Forest Products UV Wood panels!<br /><br />Ang



Hello. Is your Purebond board suitable for subfloors? I think I need to replace the floors and carpets upstairs in the 2 year old house I just bought. I am having symptoms of formaldehyde pollution. Also, can you recommend a good "green" construction company in Scotts Valley/Santa Crus California to replace my floors?

Is Purebond usable for subfloor? Q# 2025 / Submitted 2/19/2008

Our PureBond panel products meet or exceed all requirements of the ANSI/HPVA HP-1-2004 product standard, the decorative standard to which most hardwood plywood panels are manufactured. Additionally, the physical properties make it highly suitable for furniture, cabinets, book cases, entertainment centers, and even store fixtures. However, such products are just not recommended for flooring applications. Most flooring plywood products are manufactured not with a urea formaldehyde adhesive, but rather with a phenolic formaldehyde system. Both are in the formaldehyde family of adhesive systems, but phenolic systems release so little formaldehyde that they typically fall below the levels that trigger listing as a hazardous component. Because of the very low emission levels, these products should be considered safe in terms of formaldehyde exposure to all but the most sensitized individuals. You may want to check out the website www.builditgreen.org for more information for a directory of green contractors in your area. Thank you for a great question.<br /><br />Ang



Can you give me the actual thickness (including tolerance) of a nominal 3/4" sheet of prefinished Europly? Thanks.

Prefinished Europly Thickness Q# 2024 / Submitted 2/18/2008

The actual thickness will vary relative to a given shipment of core and the face and back species and cut. Typically, the thickness will range from a low of around .710" to a high around .740", again depending on the variables. Thickness variation within a given shipment of the same construction is typically much less than that which would be expected with a normal line by line lay up, usually no more than plus or minus .015". However, this is all stated with the understanding that the ANSI/HPVA HP-1-2004 Standard, which prevails in any thickness discussion, states in section 3.13 that thickness for panels having a nominal thickness of 1/4" or thicker is plus 0, minus 3/64", making the permissible range for a 3/4" panel from .703" to .750."



I need a 1/4 inch plywood product that will be cut and used as the floor board in my airplane. Strength that will resist bending is most important (not flatness or screw holding). It will not be subjected to water. Nonetheless, water resistance and stability as the weather changes are desireable characteristics. Can you recommend a specific Columbia Forest product? Would a veneer core be best?

Floor Board Q# 2022 / Submitted 2/15/2008

Our products are manufactured for their aesthetic attributes rather than their strength characteristics, and while they certainly have measurable physical properties, I would be reticent to recommend one of our 1/4" panels for your application. There are aviation grade panels manufactured from spruce and other lightweight but strong species in multiple ply constructions that would be better suited for floorboard use, and I would recommend that you check out those sources for a better fit.

I cannot find good descriptions of Classic Core, Classic Core II, and Classic Lam on the website for preparing specifications. Also, is there a Classic Lam II product? Will you identify the differences in the products?

classic core, classic lam products Q# 2021 / Submitted 2/15/2008

Classic Core, now referred to as Classic Core I, Classic Core II, and Classic Lam are manufactured as a veneer core product with all core lines except the outer most cross bands being a peeled veneer, sandwiched between outer cross bands of particleboard for Classic Core I or MDF for Classic Core II. We do have a Classic Lam II available that has MDF cross bands on the outside of the product, but does not have a face and back, making it suitable for the end user to laminate themselves.

I used your one half inch and three quarter inch purebond solid core plywood in exterior decorative panels on my house finished with one coat primer and two coats finish paint. Within two months the plywood started to delaminate and now after about 8 months there is massive delamination. If this plywood has waterproof glue why is it delaminating? I checked your website before purchasing the product to verify that it was made with waterproof glue.<br /><br />thanks<br /><br />Frank Cashin<br />3 Pleasant Ave<br />Mount Pearl, NL Canada.

Delamination Q# 2019 / Submitted 2/14/2008

Our PureBond hardwood and decorative plywood panels are manufactured and marketed as decorative interior panel products designed for use as kitchen and bath components, furniture components, interior paneling, and many other interior residential and commercial decorative applications. While the panels are produced with a very reliable water resistant adhesive designed to withstand casual contact with water such as one might encounter in a kitchen or bathroom periodically, they are not in any way intended for exterior applications. They are manufactured to Type II (Interior) requirements of the American National Standard for Hardwood and Decorative Plywood, ANSI/HPVA HP-1-2004 as approved May 6, 2004, Sections 3.11.3, 4.2.2, 4.6, and Tables 8, and 11. Decorative products manufactured industry wide to this standard are just not intended or recommended for any application where they will be subject to the forces of nature. On the contrary, they are recommended for use in controlled interior environments with a recommended relative humidity of 25-55% at 68-75o F (20-24o C). <br /><br />We actually do produce a water proof adhesive bonded panel in accordance with Sections 3.11.2, 4.2.1, 4.5, and Tables 8 and 11 to special order. However, even these products are decorative in nature and thus not recommended for exposure to outside weather conditions, but rather are designed for applications where indoor moisture may be more prone to fluctuation. <br /><br />I apologize for any confusion, but in reviewing our website, I find references to the water resistance of the product and to its use as an interior decorative product, but not as an exterior structural or even exterior decorative product. <br />

I need technical data comparing your Purebond glue product to formaldihide based glue products or seperate data so I can make my own comparison.<br />I also need tech data on purebond poplar core ply.<br />Thanks

Purebond Type II poplar core ply Q# 2016 / Submitted 2/13/2008

Our MSDS for both our PureBond products and our UF products is available on our website on the "Our Products" page on the upper right side of the page. As far as tech data, specifically with respect to poplar veneer core, the physical properties of the panel do not change because of the adhesive.

3/4x4x8 Prefinished plywood Q# 2008 / Submitted 2/1/2008

Matching the UV cured finish we applied is a matter of trial and error in most situations requiring testing with waste materials and various stains and topcoats. I would recommend acrylic polyurethane as a topcoat, but any finish material with which you are comfortable that provides a comparable sheen should be just fine. As far as repairs, a high grade wood putty and carefully applied acrylic polyurethane, while tricky at best, is your best choice. <br /><br />To be sure your question recieves the proper attention and the best answer possible, I also forwarded your question to our web finishing expert who will respond to your question as well, as he is far more knowledgeable regarding finishes than I. <br /><br />Thanks for choosing Columbia Forest Products prefinished panel products!<br /><br />Ang

Why does the quartersawn cherry veneers on a plainsliced face appear to be in a light and dark pattern or striped ?

QTR CHERRY Q# 2003 / Submitted 1/24/2008

The quarters or straight grain orientation on either side of the cathedral feature of a plain sliced cherry face, like the straight grain in the true quarters or false quarters pulled from plain sliced faces all exhibit the characteristic you describe to some extent. Some of the striping or mottled effect is very pronounced and some is barely noticeable, but a cherry face without some degree of figure or distortion of the grain is the exception rather than the rule. The causes of this characteristic are numerous, and to pin it down to any particular influence is difficult. Wavy grain can be a result of injury to the tree, genetics, growth conditions, soil conditions, climate, available nutrients, unusual weather patterns, growth on a hillside or slope, and many others. Cherry may also be susceptible to development of interlocked grain wherein the growth rings develop in a spiral configuration rather than straight up and down the main stem (trunk) of the tree. Any of these conditions can cause wavy or distorted grain that, when the wood is sawn, peeled, or sliced from the log, the end result is a cut that crosses alternating areas of flat grain and end grain, or alternating grain directions. In any event, these alternating directions retract and reflect light differently, and will take finising materials at a different rate, thus producing the striped pattern to which you refer. Hope this helps!<br /><br />Ang



We've been asked to make cabinets with English Sycamore veneer and lumber. We haven't used it before. Any recommendations for specification? Cut, grade, etc. characteristics? Thanks

English Sycamore Q# 2001 / Submitted 1/22/2008

English sycamore (Acer pseudoplatanus) is a fine hardwood found throughout southern Europe and western Asia. It makes excellent dimension stock and veneer, offering above average machining properties and finishing characteristics. Because the veneer can be somewhat opaque, it is best suited for overlaying on an engineered substrate such as particleboard or MDF to avoid telegraphing of surface imperfections from the core through the face. <br /><br />As far as grade, matching, component size, color and grain matching over the entire run, and any other particulars, this species is not listed specifically in the ANSI/HPVA HP-1-2004 Standard, and should therefore be governed as a Specialty Grade as indicated in Section 3.3.8 of the standard. This effectively means all specifications should be agreed upon between buyer and seller. Because of the trickiness of such specifications, special care should be given to ensure all expectations are clearly outlined, and all supplier cababilities and limitations are clearly understood. English sycamore can produce an absloutely beautiful finished product admired by all, but as any other high profile job, it can create a lot of consternation if all expectations are not met. <br /><br />English sycamore is also called plane, sycamore plane, sycamore, great maple, and sycamore maple. It is actually in the maple family, whereas American sycamore, also called plane or sycamore (Platanus occidentalis) is in the sycamore family, and not directly related to English sycamore.<br /><br />Hope this helps!<br /><br />Ang



WHAT IS THE TOLERANCE IN THICKNESS OF 1/4" CHERRY 4X8 MDF. ALSO HOW MUCH CONTRACTION AND EXPANSION SHOULD BE EXPECTED BECAUSE OF HUMIDITY.

HARDWOOD PLYWOOD Q# 2000 / Submitted 1/18/2008

The hardwood plywood standard, ANSI/HPVA HP-1-2004, section 3.13 DIMENSIONS AND TOLERANCES, addresses thickness as follows: "plus 0, minus 0.8 mm (1/32") except that a tolerance of plus 0, minus 1.2 mm (3/64") is allowed for panels having a nominal thickness of 6.4 mm (1/4") or more. Translation: a 1/4" panel of any construction (MDF, VC, PBC, etc.) can range from .203" to .250". Typically, an engineered core like MDF or PBC will exhibit a much tighter range, usually somewhere less than 0.010" plus or minus from the average thickness for a given run, but the standard even for this product is effectively plus zero, minus 0.047".<br /><br />For an MDF product, the ANSI A208.2 standard indicates a linear expansion coefficient of less than or equal to 0.3%. To determine the actual value, multiply the specific dimension by .003. <br /><br />Thanks for a great question!<br /><br />Ang

Do you have any graphs, charts, or data concerning strength comparisons between particleboard and plywood and moisture resistance comparisons between the two?<br />Thanks

particleboard cores Q# 1997 / Submitted 1/16/2008

Actually, because hardwood plywood is a decorative product as opposed to a structural or engineering product, there just isn't much in the way of published data for it. Particleboard and MDF by themselves are structural entities, and as such physical properties are listed for each in their respective standards, ANSI A208.1 for Particleboard, and ANSI A208.2 for MDF. As you are likely aware, veneer core plywood has exceptional physical properties compared with those 2 products, with screw holding often exceeding 300 psi from the face surface and 250 from the edge, MOR values typically greater than 7500 psi, MOE values often at or greater than 750,000 psi, internal bonds approaching as much as 200 psi, and densities ranging from a low of about 25 lbs/ cu. ft to greater than 35 lbs. cu ft. Moisture resistance is high with most veneer core products made to the Type II or water resistant specification outlined in the hardwood plywood standard ANSI/HPVA HP-1-2004. Hope this helps.<br /><br />Ang



Hello,<br />I was told by a friend that you have a a plywood product that is glued with mollusk epoxy. Is this true?<br /><br />Thank You,<br />Isaac Osborne

mollusk epoxy plywood Q# 1995 / Submitted 1/12/2008

It is true! Our PureBond formaldehyde free adhesive technology started with a mollusk. Several mollusks, to be more specific. Dr. Kaichang Li of Oregon State University developed a soy based adhesive system after his curiosity got the best of him during a clam digging excursion off the Oregon coast about 7 years ago. He didn't find many clams, but he did notice the numerous mussels clinging to the rocky outcroppings in the pounding surf, leading him to ponder how they were able to attach themselves and not be dislodged under such adverse conditions. Five years later, with funding from Hercules Chemicals and Columbia Forest Products, he was successful in mimmicking the chemical blueprint of the byssal threads the mollusks secreted that allowed them to accomplish this remarkable feat, and our PureBond adhesive technology was born. Your friend is right on track!<br /><br />Thanks so much for your interest in our PureBond story!<br /><br />Ang



I am building a sewing cabinet with 3/4" Oak veneer plywood, with the two MDF outer layers. I am concerned about the exposed edges on the bottom of the cabinet. I plan to uses oil base stain and Polyurethane for the finish.<br /><br />My concern is based on what happens when water makes contact with the exposed edge (3" above floor level). A couple of my project parts (standing on edge) were damaged by water from melted snow; my shop is part of the garage. The water soaked into the MDF and destroyed the plywood!<br /><br />My question is, how to seal the edges? Is it necessary to veneer over all the exposed edges? Any help you can provide will be appreciated.<br /><br />Don

Exposed Edges Q# 1992 / Submitted 1/10/2008

Unfortunately, any decorative panel product, whether veneer core, MDF or particleboard, is subject to the effects of water in direct contact. While these products are designed for interior use, a properly treated exposed surface typically won't be damaged by incidental contact with moisture such as wiping with a damp cloth, but they don't fare very well when exposed to water for any period of time. The polyurethane you plan to use should be applied to all exposed edges, allowed to fully penetrate and dry, followed by subsequent light coats until the surfaces are sealed and this should help. I have a similar condition with my wood working area (minus the snow) so I take great care to keep my projects elevated until I can get them into the house. I hope this helps!<br /><br />Ang



Dear Ang,<br /><br />A supplier is suggesting to chnage the rails on the cabinet doors from poplar to birch plywood. Do you know of any problems that could arise if we use Birch plywood ILO of Poplar.<br /><br />Please advise,<br /><br />FM<br />PM- BLL

Birch plywood vs Poplar for kitchen cabinets Q# 1991 / Submitted 1/10/2008

As I interpret your question, you are currently making or using 5-part cabinet doors consisting of 2 stiles, 2 rails, and an insert of some species, and a supplier of component materials is suggesting that you change the frame components (stiles and rails) to birch plywood, and you would like to know if there would be issues with this construction. If the suggestion refers to veneer core birch plywood, you will have to contend with the exposed inner plies along all edges, inside and out, on each stile and rail, and this alone would make this an undesirable alternative. The same answer would apply if the suggested birch plywood consists of a birch face and back bonded to a particleboard core (PBC). If, on the other hand, the suggestion refers to a birch face and back with an MDF core, this could be a viable alternative as the MDF machines well, and the edges can be finished to match many darker stains, but the advantage over solid dimension lumber is still not clear. Your best bet is to have your supplier clarify what they are suggesting and give you a clear demonstration of how their suggestion would be implemented and what the end result would be. At that point, it should be an easy call.<br /><br />Thanks for a great question!<br /><br />Ang

I've been woodworking for 30 years. I'm more and more disappointed by the "thinning" of today's plywood. I find your panels sold as 3/4" thick can range from 11/16" to 23/32" without any consistency. This makes construction very difficult. I'd really like to be able to buy true 3/4" thick plywood, and I'd be willing to pay more for such. Please consider making this change. Thanks. Bruce Kieffer

3/4" Plywood Q# 1984 / Submitted 1/4/2008

This is, unfortunately, a frequently heard complaint going back as far as the first product standard for decorative panel products in 1935, when the nominal thickness of the inner ply veneers was greater than today, and face and back thickness was far greater than today. There are a number of critical factors that contribute to this. The most obvious is cost based on a highly competitive marketplace, with yield being a major contributor. Most 3/4" panels consist of 5 plies of 1/7" or 7 inner plies of 1/10" thick veneers of a softwood species or lesser value hardwood species than that of the face and back. Both of these thicknesses are cut to a slightly thicker target, but due to drying loss, they generally approach the actual thickness. Over time, those targets seem to have gradually shrunk as a result of intense pressure on yield as well as pricing from so much competition that now the end results are slightly less, and when you multiply that over 5 or 7 plies, that amount can become significant. Additionally, due to the highly variable attributes of wood, that thickness within individual components can vary, even if the equipment is perfectly aligned. Compound that with the number of manufacturing variables (knife/pressure bar set up, drying conditions, moisture contributed by adhesive, sanding variation, and ambient conditions during assembly, and it is easy to see how thickness can vary. This situation has long been addressed by tooling manufacturers and mail order catalog centers who routinely offer "plywood" router bits that are usually 1/32" undersized. <br /><br />The American National Standards Institute ANSI/HPVA HP-1-2004 product standard does place limits on thickness in section 3.13 to the extent that panels having a nominal thickness of 1/4" or more cannot vary more than plus 0, minus 1/32" in unsanded panels, and plus 0, minus 3/64" in sanded panels. <br /> <br />Columbia Forest Products does produce a panel with a more consistent range than the industry standard allows with our JayCore and KayCore veneer core panels, but even so the end result is still typically slightly under the full 3/4". However, we do continuously strive to improve our products so that they meet consumer needs, and we do listen to input such as yours to help us in that endeavor. Thank you so much for a great question.<br /><br />Ang



How strong (tensile strength and lamination integrety) is this product? I am building another sailboat. I have used 1/2" luan in the past with good results but I wonder how this product would compare.

blondewood panels at Lowe's Q# 1983 / Submitted 1/2/2008

"Blondewood" is a trade term that has been loosely applied to any number of light colored, usually all sapwood species faced panels from various regions around the world. Typically, panels so described are what some might call "all purpose" or "utility" panels that can be used for a variety of applications. They normally have a water resistant (not usually water proof) adhesive and innerplies of reasonable strength and other properties. Unfortunately, that very generic statement is probably the best I can do as it would be imprudent for anyone to attempt to provide technical information on any species based on such a vague trade name alone. Even if we knew the botanical name of the face species, we would still need to know the exact construction of the panel (number, thickness, and species of all inner plies) and the adhesive to provide answers to the questions you justifiably ask. Your best bet would be to contact the local store to see if they can provide answers through their supply chain to the actual manufacturer. So sorry I couldn't have been more helpful.<br /><br />Ang

Have there been an increased incidence of delamination of Baltic Birch plywood this year?

Baltic Birch Plywood Q# 1977 / Submitted 12/18/2007

There has been no recorded increase in incidence of delamination from any of the baltic/russian birch sources in 2007. While delamination avoidance is a critical focus of all decorative panel products manufacturers, it is influenced by so many variables, mostly involving time, temperature, and moisture control, that it is impossible to totally eliminate. However, for the most part it is not rampant, although when it is encountered it may seem so. But no, to our knowledge there is no exceptional activity around complaints of delamination over the last year. <br /><br />Ang

We need to change the gloss value on our prefinished maple PureBond plywood. Should we top-coat with another product? Which one? Just buff? What product(s)?<br /><br />Thanks<br /><br />Mick Harper

prefieBond Q# 1971 / Submitted 12/11/2007

Your pre-finished panels provided by Columbia Forest Products are cured with ultra violet light to an extremely hard, durable finish that is not conducive to additional topcoating. It is highly chemical resistant, making it challenging at best to over coat. If you decide to attempt this with existing stock, I would highly advise you to check with your finish supplier of catalized lacquer to determine compatibility. Upon confirmation that it is compatible, you will need to aggressively but carefully sand the surface with a 220 grit coated abrasive to provide a rough texture for the lacquer to bite, then spray the surface to the gloss level you desire. Even with all this, there can be absolutely no garantee for success. Obviously for the future your best bet will be to contact your field service rep who sells you that particular product and request a different gloss level. Hope this helps.<br /><br />Ang



I'm looking for 1/2" thick 4'x8' beaded plywood. 1/4" is eay to find. I need 1/2 inch. Can you help?<br />Thanks

"Beaded" Plywood Q# 1970 / Submitted 12/8/2007

For beaded board it must seem to most users that 1/4" is the standard, and indeed that is far and away the most commonly offered thickness for most local dealers and big box centers. Columbia Forest Products actually beads panels of all thicknesses within a normal range of available panel product thicknesses. Unfortunately, the runs are all based on actual customer orders, and not for an inventory for spot purchases. If your need is small, you may be able to locate a local millworker who can do that for you, but please be aware that a custom set up will be costly. However, depending on the size of your project, that may not be an issue. If you need larger quantities, you may want to conduct a dealer search from our site, locate a dealer near you, and ask them to determine pricing and availability for a larger custom run from our facilities. Hope this helps. Thank you so much for your interest in Columbia Forest Products.<br /><br />Ang

veneer thickness Q# 1969 / Submitted 12/7/2007

The outer veneer (face) thickness of the cherry panel depends on the source, but is typically 1/36" or thinner. There are custom manufacturers of veneer who can cut the faces much thicker, up to 1/8", but this requires a special arrangement to utilize the entire log. If your needs are small, you may locate a local millworker who can resaw small amounts of cherry solids to thin layers, but this is tedious and time consuming. If you are a manufacturer with relatively large volumes, please let us know and we will gladly discuss your needs and how we may serve you better. Hope this helps.<br /><br />Ang

Do you make or know of a company that makes OSB w/ nontoxic binders?<br /><br />Thanks!<br />Ruth Crump

oriented strand board w/ no/low VOCnon formaldehyde adhesives Q# 1967 / Submitted 12/3/2007

Most OSB (Oriented Strand Board) is manufactured with a phenolic formaldehyde adhesive system that is not that dissimilar from the thermoset plastics frequently used to make durable plastic dinner ware. This material does utilize formaldehyde, but this family of compounds typically is very effecient at binding most of the formaldehyde molecules in the finished product, thus leaving very little free formaldehyde to volatilize (off gas) over time. In fact, EPA and other agencies have suggested in the past that phenolic formaldehyde adhesives are safe substitutes for urea formaldehyde frequently found in interior building products. I don't know of a manufacturer of OSB using adhesives other than PF. We are continuously working with different companies to develop building products utilizing our formaldehyde free binding systems, but as of today, OSB products are not among them.

What is the flame spread rating on a 3/4" A1 Maple veneer with MDF core sheetstock?

Flame spread rating Q# 1962 / Submitted 11/19/2007

The American Forest & Paper Association publication, "Design for Code Acceptance," lists flamespread values for a wide variety of wood and panel products for general information to show that most untreated wood products develop a flamespread between 76 and 200, which is the range published for Class C as set forth by the National Fire Protection Agency, NFPA-101. The rating system is based on a value of 100 for red oak flooring. Smoke developed for panel products is 450 or less. <br /><br />Like most panel products manufacturers, we rely heavily on the above publication for our statements that most wood products, including 3/4" A-1 Maple on MDF meet Class C. There is no way to give the actual rating for any given product because the flame spread test is destructive in nature. This means all producers and users must rely on comparable data developed from testing on like products. Hope this helps!<br /><br />Ang

Structural plywood Q# 1958 / Submitted 11/10/2007

Structural plywood is manufactured with a phenolic-formaldehyde product that emits formaldehyde at such a low rate that it doesn't require reporting on a material safety data sheet. There are structural plywood products manufactured specifcally for use as sub-flooring, and these would be very low in formaldehyde emissions. Most of the odor in these products comes from the softwood components (spruce, pine, and/or fir), not the adhesive, and even these odors will dissipate in short order.<br /><br />Our products are manufactured for aesthetic applications, such as components for kitchen cabinets or furniture. The faces are very thin, which works well for visual effects, but is just not conducive to use as a flooring or sub-flooring product. <br /><br />I wish I could be of more help.<br /><br />Ang<br /><br />



What is baltic birch scientific name?

Baltic birch Q# 1957 / Submitted 11/5/2007

One would be inclined to think this is a simple question. However, there are some 30 to 50 species of birch commercially harvested at some level throughout the world. Of these, there are 4 major ones in the US, about the same in Europe, and at least a dozen in Asia. In the US, B. alleghaniensis (Yellow Birch) is the most common, followed by B. papyrifera (Paper Birch). There are all sorts of trade names (most inaccurate) surrounding these two species, from white birch (actually lighter colored sapwood from any birch tree), red birch (actually darker colored heartwood from any birch tree, hard birch, and swamp birch, to name a few.<br /><br />In Europe (including the Baltic region where much birch is cut as veneer and produced as Baltic Birch, Finnish Birch, or sometimes even Polish Birch), and in Russia where it is obviously sold as Russian Birch, the more common species are Betula pendula (formerly B. alba), also called Silver Birch or White Birch, and B. plubescens, sometimes called Flame birch. B. pendula has been established in some regions along the Canadian/US border, but it does not usually reach harvestable size. It is occasionally referred to as bouleau, or white birch by many locals, as the sapwood of this particular species does tend to be lighter in color than most.<br /><br />Although rare, an occasionl layer of other species may also be found in these products, usually Populus tremula or European Aspen.<br /><br />All the birch species have similar physical properties, including specific gravity somewhere around .6 to .7 or higher, and a typical dry weight range from 38 to 45 pounds per cubic foot. All have respectable mechanical properties, machine quite well, and take finishes moderately well. <br /><br />Hope this helps!<br /><br />Ang

Why do you not manufacture osb? Does osb not use smaller diameter trees so that it is more environmentally friendly?

osb vs plywood Q# 1952 / Submitted 10/31/2007

We manufacture hardwood and decorative plywood on a wide variety of substrates, including, on occasion, oriented strand board. We do not manufacture that core product, however, because it is sold more for its structural properties, and is manufactured by numerous producers who specialize in products for that purpose. Our product, on the other hand, is sold for its aesthetic attributes, and OSB has a tendency to telegraph surface imperfections through the thin decorative faces, thus rendering our product unacceptable. <br /><br />In terms of environmental conscience, however, our products have always been green friendly, and in more recent times have become even more so. The faces that we use for our decorative products that come from the precious resources are only 1/36" or thinner, compared to solid wood which is up to 1 1/2" thick or thicker. This greatly expands the availability and thus extends the supply in a very environmentally responsible way. Because you see the wood only in 2 dimensions (length and width) we have the capability of building the thickness of our products using veneers from widely available and quickly replinishable species like poplar and pine, as well as the engineered cores like particle board and medium density fiber board, both of which utilize a lot of post industrial waste for the fiber content rather than requiring additional harvest of trees. Additionally, we produce FSC certified panel products, meaning some or all the contents can be tracked back through a chain of custody to the source of the log(s) and that the trees harvested for that product were managed in accordance with recognized environmentally responsible practices. <br /><br />Hope this helps.<br /><br />Ang

I operate a small cabinet shop and recently purchased five sheets of your 3/4" Oak Plywood from a local retailer. On the invoice the plywood is referred to as #1 Grade. The edge of the plywood is clearly marked as B-2. I questioned the retailer about this and was told that the B-2 grade was #1. Is B-2 ever referred to as #1? I would think A-1 would be #1. This B-2 is terrible stuff to work with. I haven't found a blade yet that will cut it without splinetering. If this stuff is what is being sold as #1 I will be looking for another supplier for my next set of cabinets I build.

Plywood Grades Q# 1947 / Submitted 10/26/2007

Without knowing more specifics of your purchase, it is difficult to comment other than to let you know that there is no such thing as a #1 hardwood plywood grade in terms of commercially accepted terminology. The American National Standard for Hardwood and Decorative Plywood, ANSI/HPVA HP-1-2004 lists 6 face grades, AA, A, B, C, D, and E, with AA being the highest, and four back grades, 1, 2, 3, and 4, with 1 being the highest. (This standard is available for purchase from the Hardwood Plywood and Veneer Association in Reston VA USA at hpva.org or 703-435-2900) Panels are typically sold with a designation that lists the face grade first, followed by a dash (-) and then the back grade. A typical panel sold to a distributor or dealer might be labled B-2, but not simply a #1. Individual retailers may utilize a proprietary labeling system for their own inventory purposes, and that could possibly explain the seeminly conflicting nomenclature.<br /><br />Having said that, a B-2 grade panel should be a relatively good quality product, with a face having some, but not excessive amounts of natural character to include things like mineral streaks and small knots. The back will usually be slightly lower in grade with more pronounced characteritics. <br /><br />None of that should have any bearing on the splintering of the panel face when cut across the grain. Splintering is difficult to avoid with most saw blades on the market, but the higher tooth count combination blades and cross cut blades available should help you minimize it. Additionally, orienting the panel so that the cut takes place when the saw enters the face side rather than the back side should help, too. Many larger manufacturers utilize a scoring saw to slightly cut into the face ahead of the main saw blade, but you can accomplish the same thing if you score the cut line with a utility knife and a straight edge before you saw the line. <br /><br />In any event, if the splintering protrudes more than a quarter of an inch, and there is no core material attached to the splinters, the problem could be poor adhesion. This is an uncommon problem, but it can occur from any manufacturer, and when it does, your only real remedy is to take it back to the dealer and have them contact the supplier for verification and credit if that is indeed the situation.<br /><br />I am sorry you are experiencing problems with the product, and hope it can be resolved to your satisfaction in an expeditious manner.<br /><br />Ang

I purchased Maple engineered hardwood flooring. Brand name is Floors of Distinction, but UPC is registered to Columbis Forest Products (7 30312 93409 9 is the UPC on the trim). After the floor was laid, I discovered one board has a footprint from a sneaker UNDER the finish. So my question is what is the finish on the wood. It's maple without a stain. If it's a laquer finish, I thought I could sand the smudge away and sprayt it with a clear laquer.

Engineered Hardwood Flooring Q# 1942 / Submitted 10/21/2007

You will find sanding this finish and applying a new one to be a challenge. The finish is an ultraviolet light cured acrylic polyurethane that is chemical, abrasion, cleaning solvent, and moisture resistant. It is much more durable than anything you can apply by hand. If the footprint is indeed under the finish, I would recommend taking the issue up with the dealer, who should be happy to replace it for you. If all else fails, I would recommend you contact the manufacturer (we have since sold that division to Mowhawk Industries) to seek assistance. <br /><br />Ang



I read the letters in the archives and am confused by one (26 march 2007) "what does no addedformaldehyde mean" you wrote that there is no UF if the plywood is made from scratch on an all vneer core with whole piece face" It seems impossible to know as a consumer if the middle ply of a plywood is "whole piece face" and thus impossible to know if I am actually purchasing a UF free piece of wood, even though it is marketed as UF free. Please help this make sense.<br />Thanks!

pure bond plywood Q# 1941 / Submitted 10/21/2007

"Whole piece face" refers to the decorative (usually hardwood) face and back of the panel, not the inner ply or core components. With veneer core and PureBond construction, there is no formaldehyde used to bond any part of the inner plies. When our spliced face and back veneers come from outside our company, they usually are spliced with a UF glue. While the amount of glue thus used is very small, it is not formaldehyde free. Therefore, I referred to panels with PureBond construction and whole piece (not spliced) faces and backs (not inner plies) as being formaldhyde free, excluding any trace amounts that could possibly leach out at the molecular level from the wood itself. This can certainly be very confusing, but I hope this helps. Thanks for a great question.<br /><br />Ang



Some places on your web site you refer to purebond plywood as formaldehyde free and other places (your letters section) you write that it is urea formaldehyde free. These are two very different statements and I'm curious which one is more accurate. Is purebond a phenol formaldehyde products combined with soy.<br /><br />Thank you very much,<br />heidi

purebond plywood Q# 1940 / Submitted 10/20/2007

There is an argument that any organic material will emit traces of formaldehyde during its life, albeit in what may very well be considered immeasurable amounts. For this reason, I have occasionally referred to our panel products manufactured with all veneer core inner plies and faces and backs that have no splice joints as urea formaldehyde free to hold off those obsessed with minutae. There is no formaldehyde in our panels manufactured as indicated above, and no adhesive from the formaldehyde family (phenolic, melamine, resorcinol, or urea) is used to produce such panels. The adhesive we developed for these panels is a soy based product utilizing the same wet strength component used in facial tissue, paper towels, and paper currency. Hope this helps.<br /><br />Ang



My husband has made a cabinet and used oak veneer for the shelves. The one shelf was sanded too much and now some red spots have appeared where it was sanded. Someone said that the glue is showing through. I tried to stain it with an Early American stain and you can still see these red spots in the grain of the wood. Is there anything we can do to cover these red spots?

oak veneer Q# 1939 / Submitted 10/19/2007

Some of the panels sold at retail lumber yards and home centers are imported from other countries that cut the veneer extremely thin. Additionally, many of them use an adhesive that does have a red color to it. Unfortunately, the combination of these conditions means #1 it is easy to sand through the face, and #2, the glue (red or otherwise) will serve as a barrier to the finish. I know of no way to satisfactorily address the problem other than replacement of the offending component, or, at the very least, purchasing a piece of paper or phenolic backed oak veneer from a local source or one of the mail order catalog centers such as Woodcrafters (http://www.woodcraft.com/depts.aspx?DeptID=2122) to apply over it. Hope this helps!<br /><br />Ang

Are there sheets somewhere that will give me a net thickness of a panel vs the nominal thickness?

PANEL THICKNESS Q# 1937 / Submitted 10/17/2007

Not that I know...Nominal (from the Latin meaning in name only) thickness loosley translates to the total thickness of the components in a panel as they relate to a target thickness for the finished panel. For example, a 3/4" panel consists of any number of combinations of components, few of which actually add up to 0.750" exactly. Some are very close, and some are as much as .025" or more under. The industry has recognized this quandry since its inception in the early 1930s, and thus Section 3.13 of the ANSI/HPVA HP-1-2004 Standard says, in short, "the nominal dimensions of plywood panels shall be as agreed upon between buyer and seller. The tolerances for the nominal dimensions shall be as follows: ... thickness ... unsanded ... plus 0, minus ... 3/64" for panels having a nominal thickness of 1/4" or more." Whereas I have obviously excerpted the above, please refer to the standard for the complete statement. Hope this helps.<br /><br />Ang



Can you provide a comparison either in full-sheet weight, or in cubic foot density, of Classic Lam or Classic Core compared to some other VC plywoods you produce? Also, on the Classic Lam product, are the exposed faces actually MDF?<br /><br />Thanks!

Classic Core/Classic Lam questions Q# 1936 / Submitted 10/16/2007

The edges of the outer most plies directly under the face and back of Classic Core II are MDF. Because these products are designed for aesthetics rather than structural strength, we do not have a formal physical properties document we can circulate. Additionally, the properties vary slightly based on the remainder of the species used in the panel. You would normally expect the density to increase by 10-20%, depending on whether the other plies are poplar or fir/pine. The mor/moes are not that different from regular vc, ranging from slightly better with fir/pine inner plies to slightly less for panels with poplar inner plies. The value of Classic Core lies in the smoothness of the substrate directly under the face, translating to more uniform thickness and less telegraphing of surface imperfections common in regular veneer core construction. <br /><br />Ang



Do you also manufactuer regular soft wood plywood with your pure bond glue, if not do you a company that does.

soft wood plywood Q# 1935 / Submitted 10/12/2007

We do not, but regular softwood plywood is usually manufactured with phenolic adhesives that, while they do contain formaldehyde, emit at levels so low as to be considered "de minimus" (inconsequential) by the regulatory agencies. Emissions at or below such levels are considered safe.



We use your Pure Bond 3/4" Red Oak and Poplar veneer plywood. We also use the 3/4" MDF. I need to know the veneer thickness for these two materials. Thank you.

Veneer Thickness Q# 1934 / Submitted 10/12/2007

If the face and back veneers are rotary cut, they typically start out as 1/36" or .028". If they are sliced, they are more likely 1/42" or .024". You can deduct .004" to .008" per side for sanding on either cut. Hope this helps.<br /><br />Ang

What is the minimum radius in which 3/8" bending ply will bend?

3/8" bending ply Q# 1931 / Submitted 10/10/2007

I still have my original drawing and specifications which I scribbled out in 1989 to include a bending radius for what was then 3/8" bending plywood. That radius was 7", but with today's highly variable sources of supply, I would not hold to that number. Subsequent proprietary specifications I have found indicate a 16" radius, which I consider probably closer to what you might experience. In any event, the panel or component should be sufficiently "flexed" back and forth to achieve the tightest radius possible.



What is the mosture content and water resistance for AC plywood

Ac plwwood moisture content Q# 1930 / Submitted 10/10/2007

"AC" is a designation of the softwood plywood manufacturers, typically produced with a spruce, pine, and/or fir construction. The moisture content will vary between 6 and 15%, but is usually under 12%. The adhesive used is phenolic based, making it fully waterproof, although the wood itself left untreated is still subject to the effects of exposure to its environment.



Is there any acetone, or heavy metal etc in the Pure Bond plywood. Is it zero emission or should it still be sealed? Thanks

Pure Bond Q# 1929 / Submitted 10/7/2007

There are no heavy metals, VOCs, or MEKs (like acetone) in the formulation. Sealing is typically recommended for any decorative wood product, but that is for protection of the wood rather than as a barrier to chemical off-gassing in most cases, particularly in the case of PureBond panels. Thanks for a great question.<br /><br />Ang

Your best bet is to locate a source for marine grade structural softwood plywood. These products are manufactured specifically for uses as you have indicated. Our products are interior decorative products just not suited to your application. I can't recommend this, but I have seen people successfully use 2 pieces of 3/4" B-B concrete form construction, glued together to produce a 1 1/2" thick piece (or thicker with more layers) to use as a boat transom in smaller boats, but the marine grade is best suited for your use.

concerning IPB or MDF: We are a wood components manufacturer and require a core with no metal fragments for a medical cart application. the cart will be used in an MRI room so the specification calls for a non-magnetic material. Plastic is too expensive. Do you offer a "certified" material that meets this requirement?

metal fragments in core Q# 1925 / Submitted 9/28/2007

All manufacturers of engineered wood components have metal detectors, strong magnets, and tight qc measures in place to prevent the incidental inclusion of ferrous particles in their products, but I also know that irrespective of these precautions, such inclusions are inevitable. Unfortunately, I know of know one out there who makes a specialty product that they certify for such applications as indicated. I can understand the requirement, as embedded metal particles could conceivably become highly agitated by the magnetic field generated by the imaging equipment, and this could potentially pose an injury hazzard to patients. I would consider investing in a high quality metal detector which could be used to sweep conventional pbc/mdf for the presence of metal particles if you are unsuccessful in locating the certified product you are seeking. Sorry I couldn't have been more help.<br /><br />Ang

We make casework for schools. We need to provide termite-resistant material. The best core material we can find is Extira. Do you veneer this material or something else for this intent? Thank you.

termite resistance Q# 1917 / Submitted 9/19/2007

Typically, products used for interior cabinetry are not termite treated as they are used in applications not at all conducive to termite infestation, even in high risk areas. Dry wood termites would be the only real threat, but normal pest control measures would preclude infestation in all but the rarest cases. Subterannean termites attack only wood in contact with the ground or in contact with foundations close to the ground as they do not tolerate exposure to light. Extira is a vinyl and cellulose composition designed for exterior trim work and is not really practical for interior cabinet core. This question comes up periodically, but ultimately most folks defer back to conventional cabinet construction with reasonable assurance that under normal applications they are not likely to suffer any termite assault. Hope this helps.<br /><br />Ang

What is the difference between Kay Core and Composed Core

KAY CORE AS APOSE TO COMPOSED CORE Q# 1911 / Submitted 9/6/2007

KayCore is a Columbia Forest Products trademark for our pre-manufactured veneer core substrate designed to meet the requirements for "K" grade core in accordance with the ANSI/HPVA HP-1-2004 Standard for Hardwood and Decorative Plywood. Composed core means the individual core layers are assembled from random widths of veneer of the same thickness bound together edge to edge with a high tensile strength string and hot melt glue to form afull sized 8X4 cross band or 4X8 long band. These individual layers, thus composed, are then subject to the grading rules outlined above. <br /><br />Please feel free to contact us if you need additional information.<br /><br />Thanks for your question!<br /><br />Ang



Building cabinets ....which is better for strength, moisture , durability ? Any insights to the use of naf would be appreciated. Thanks DB

wood vs naf Q# 1910 / Submitted 9/5/2007

NAF is an abbreviation meaning no added formaldehyde, so I must assume you are referring to a comparison between an engineered wood product (veneer core, mdf, or pbc decorative plywood) versus solid wood. Actually, veneer core plywood is stronger parallel to the grain than solid lumber due to its construction with every ply having a grain direction at right angles to the adjacent veneers. Using a no added formaldehyde product or a formaldehyde free product such as our PureBond veneer core panel has the advantage of reduced voc's (volatile organic compounds), so there are improvements in indoor air quality and less respiratory stress. <br /><br />Whether solid wood or a composite of multiple components, wood is still subject to the effects of moisture. Veneer core plywood does have a little more resistance to shrinkage across the grain, again due to the alternating grain direction of the components.<br /><br />Hope this helps.<br /><br />Ang

Since I am separated from our mills, I cannot say specifically which mill produced this material. What I can say is that the adhesive is not phenolic. Since it is a veneer core item, there is a very strong liklihood that the adhesive is our PureBond proprietary urea-formaldehyde free, water resistant adhesive, but there is a very slim possibility that it could have been produced with a urea-formaldehyde adhesive as our conversion is not fully completed at this time. For best information in this particular situation, you may have to backtrack the paper work to determine where you acquired the material, from whom your source acquired it, and so on until we can determine which mill produced it (We have 7 hardwood plywood mills in North America).

"aircraft plywood" Q# 1899 / Submitted 8/21/2007

Aircraft-grade plywood is manufactured to specification (MIL-P-6070, I believe) of either birch (betula spp.) or African mahogany (Khaya ivorensis) veneers using highly selected grades of either basswood (tilia americana) or yellow poplar (lyriodendron tulipifera) as inner plies and a water proof glue, usually phenolic or resorcinol. Typically, the inner plies are no thicker than 1/16". Generally, the product is subjected to a shear force after a boiling water soak in order to pass the rigid requirements of the standard. Unfortunately, we do not manufacture this product. I would suggest searching the web for aviation grade plywood sources.

We manufacture veneer panels using veneer core plywood. I have a few questions as follows:<br />1. What is the maximun allowable warpage that we should allow on core before it is pressed?<br />2. Will flat veneer core warp that has had a face & back pressed to it warp during shipping?<br />3. What can be done to control warpage?<br />Thanks,<br />Mark Kruer<br />Architectural Panel Manager.<br />Flexible Materials, Inc.<br />New Albany, IN 47150

Allowable Warpage on Veneer Panels Q# 1894 / Submitted 8/17/2007

Mark, warp is a confounding problem that has plagued our industry since the development of the first commercial decorative plywood panel. The term itself is actually a catch-all for any deviation of a panels surfaces from a flat plane. Warp in panel products includes cupping, bowing, and twisting. Bowing and cupping occur along the edges and ends, and are generally a result of imbalances in moisture in the panel. If a panel is bowed or cupped, it will have observable warp, but if it is placed with the cupping or bowing (or both) oriented away from a flat plane, all four corners of the panel will touch the surface. Twist, on the other hand, is usually a symptom of an unbalenced panel, whether by construction design, different face/back species, variations in mc and physical properties, excessive or insufficient adhesive, or other contributing factors, and if placed on a flat plane, one of the corners will not touch the surface. <br /><br />To address your specific questions, first, there is no standard per se for warp of decorative panels, although AWI does address it in section 1300-T-21 (Eighth Edition, 2003) relative to architectural flush doors. Typically, warp is evaluated on an individual basis relative to decorative panels.<br /><br />Secondly, flat veneer core will most certainly warp after it has been pressed and possibly during shipment if any conditions change relative to moisture movement that could affect the panel.<br /><br />Third, minimizing warp (eliminating it would be difficult) involves the following:<br />1: Use of MDF or particleboard for architectural products is probably more often preferred due to the inherrent stability of these products. Veneer core, an outstanding product for many applications, still has a lot of room for variation in the individual components to intefere with the flat plane of the panel. <br />2: What ever you do on one side of a center line in a decorative panel, you should do on the opposite side of the panel. Translation: in a 3-ply product the core is the center line. If you apply 28# of glue per msf on one side of the core, you must apply 28# on the other. If you then put 1/42" PS Sap Maple on the face, you should use 1/42" PS Sap Maple on the back. If the face is 9% mc, the back should be 9%, and so on...<br />3: All components should be acclimated to the same conditions prior to pressing.<br />4: Panels should be allowed to acclimate again after pressing. This should be done under controlled conditions with the panels stacked flat on uniform size runners (stickers, 2X4's etc) and weighted down with another unit of plywood or MDF for at least 24 hours.<br />5: Panels should not be exposed to extreme conditions if at all possible. Best conditions are from 30-60% rh at temps from 60-75 degrees F. <br />6: Panels should be allowed to acclimate to conditions in the fabricator's shop before being processed.<br />7: Cut parts should also be allowed to acclimate before assembly.<br />8: Panels and parts should not be installed on a jobsite until the HVAC is operational and conditions are in the range listed in #5 above.<br />9: If panels are finished on one side, they should be finished on the other.<br /><br />This is a short list of the precautions that should be taken, but it should provide some indication of the special care and handling required to minimize warp.<br /><br />Sure hope this helps!<br /><br />Thanks for a great question!<br /><br />Ang<br />

What is the difference between pre-finished Maple vs Birch Plywood? <br />What is the difference in price?<br />If I wanted Maple Plywood and I got Birch Plywood is it the same, because my closet guy is telling me its the same.<br />Thanks in advance,

Maple vs Birch Plywood Q# 1887 / Submitted 8/9/2007

Birch is betula spp, usually betula allegenesis or yellow birch. Maple is acer spp, usually acer saccharum or hard maple (sugar maple). They are distinctly different species botanically speaking, but they have been used almost interchangeably for many years in the furniture, plywood, and cabinet trade. In years gone by, birch was more expensive, and much more in demand, with maple serving as a "poor man's" birch. Today the roles are reversed with maple being much more in demand, and birch being less expensive and somewhat more readily available as a result. They both are dense, tight grained woods that take stain similarly, although maple has much smaller wood cells and takes on finish more grudgingly.

I am building a kitchen out of cherry and I purchased my plywood from lumber products. The 3/4 arrived with black blotches. I am using pre-catalyzed clear lacquer as my finish. How do get rid of the blotching to get a clear uniform color on the veneer?

Cherry plywood black blotches in raw state Q# 1885 / Submitted 8/8/2007

This sounds like end grain figure with what may be glue bleed through in the actual proes of the wood if it is visible prior to finishing. It would be helpful if you could get a sample to the mill so that they may send it to me for physical evaluation as it is sometimes difficult to diagnose such problems from a description. I will be happy to take a look at the sample and offer any assistance I can.<br /><br />Thanks!<br /><br />Ang



We would like to use a wood panel product with exposed edges for a furniture application. IT would receive a clear laquer finish on most parts and some surfaces would receive a plastic laminate finish. All edges would be exposed revealing the inside of the board. Which product can you recommend for this type of application?<br />thanks

wood panel products Q# 1883 / Submitted 8/7/2007

If you wish to reveal a multi-color, fine lined edge, our Europly would fit the bill. Similar products such as curved parts have been used in institutional furniture for years in class rooms and lunch rooms. If you want an inoccuous edge that will take a sealer and topcoat, MDF would be your better choice. Beyone that, many furniture makers utilize particle board or MDF and apply a solid lumber edge to hide the core material.<br /><br />Hope this helps.<br /><br />Ang



Is beaded plywood available in 3/4" 4x8 panels?

Beaded panels Q# 1881 / Submitted 8/1/2007

We do produce 3/4" 4X8 Beaded for various distributors and end users, but unfortunately that is not such a common item that it would be easy to find. You may want to do a dealer locator from our website and contact as many in your area as you can find. If they have to special order the product, there are minimums to consider, but if they carry the product, you will be good to go. Thanks so much for your interest in Columbia Forest Products!<br /><br />Ang



What on-site laminate adhesives do you recommend for use with Pure-Bond wood to maintain the zero added formaldehyde quality?

NAF Laminates Adhesives Q# 1880 / Submitted 7/31/2007

Unfortunately, on-site you are pretty limited to contact adhesives. These are, as I understand them, formaldehyde free, but they are high VOC emitters in raw form. Once cured, the VOCs are diminished to negligible, and they provide a safe and durable bond. I also believe there are low emitting contact adhesives available, but you can verify that at your building supply store.<br /><br />Otherwise, PVA adhesives, particularly fortified versions as available from sources like Franklin, work well in the shop if you have the ability to press the laminate in place long enough for the adhesive to cure.<br /><br />Hope this helps!<br /><br />Ang



"It is accurate to state, however, that the use of PureBond urea formaldehyde free adhesive to bond a face and back to an E-1 core would not change that rating at all. The product should still emit at the E-1 level or lower."<br /><br />But is it accurate to state that the Europly core meets E-1 standards? I just want to make sure I'm not making incorrect claims for my product.

In an answer given on your site on 5 Oct 2006, you state that Europly meets European E-1 formaldehyde standards, which is .13 PPM. I also understand the face veneers are now applied using PureBond, which should make the total even lower. Yet on the Europly product page, you describe it as containing .3 PPM formaldehyde. I would like to able to advertise E1 compliance. Can I get a definitive answer as to which number is correct?

Europly Formaldehyde Content Q# 1875 / Submitted 7/23/2007

Currently in the US, the standards to which our products apply are the HUD and ANSI/HPVA standards, both of which allow a maximum of 0.3 ppm emissions for formaldehyde. Therefore, a product sold in the US that emits formaldehyde may emit no more than 0.3 ppm, but it can certainly emit less. Our PureBond panels manufactured with veneer core do not incorporate urea formaldehyde in the bonding between the veneer plies, so it is essentially urea formaldehyde free, and not subject to inclusion in the MSDS. However, our Europly panels, even when the faces and backs are bonded with our PureBond adhesive, do still emit levels slightly over the reporting threshhold for formaldehyde for inclusion in the MSDS. Since the only standards applicable in the US are the two mentioned above, those are the ones we have to list. It is accurate to state, however, that the use of PureBond urea formaldehyde free adhesive to bond a face and back to an E-1 core would not change that rating at all. The product should still emit at the E-1 level or lower. Hope this helps.<br /><br />Ang

I have two technical questions regarding Purebond plywood:<br /><br />1) What is the smoke developed index rating?<br /><br />2) What is the flame spread index rating?

Smoke Developed Index Q# 1873 / Submitted 7/19/2007

For most wood products, flame spread test results for otherwise untreated samplings tested in accordance with test method ASTM E 84 range between 76 and 200, or Class C or III as set forth by the National Fire Protection Agency. This rating applies to the majority of wood products regardless of adhesive. The Smoke Developed index is 450. The wood products industry typically relies on these comparable results inasmuch as actual tests are destructive in nature to the extent that actual tested material is rendered useless. For more information, you may wish to visit the website of the American Forest and Paper Association at afandpa.org and look for their publication Design for Code Acceptance which lists a wide variety of products the association tested to produce these results. Thank you so much for a great question!<br /><br />Ang



I want to specify a formaldehyde-free plywood to use under Hardibacker in our baths behind tile. Would need 1/4".<br />I can't determine if Purebond plywood is suitable. Looks like it only comes as a veneer product for cabinetry and such.<br />Help!

Purebond as construction material Q# 1872 / Submitted 7/19/2007

Our PureBond decorative plywood panels are suitable for most indoor applications, but the adhesive is water resistant, not water proof. I would not recommend it for your application, deferring instead to 1/4" or 3/8" construction grade plywood. This product is manufactured with phenolic adhesives, which, though they do emit trace amounts of formaldehyde, the levels are so low as to be below the minimum safe levels established by the regulatory agencies.

Just want to find out if this product exist.It is called sorghum.

sorghum Q# 1870 / Submitted 7/17/2007

Sorghum is, as you know, a grain plant similar to millet, but its relationship to wood products would probably refer to its potential use as a fiber furnish for engineered wood products such as wheat board. As a specific product, as far as I know, it is not currently on the market, but it is probably included in research to develop such a product for future use as a green friendly, environmentally conscious substitute for wood based panels. If we learn more we will definitely let you know!<br /><br />Thanks!<br /><br />Ang



What grade of PureBond plywood should I use as the base for making mosaics? (Indoor use only.)

Plywood Q# 1869 / Submitted 7/16/2007

I'm not sure of your intentions, but if you plan to pour a mastic and grout in mosaic tiles or the like, but will still leave a portion of the decorative surface visible, almost any grade would be suitable. Your choices would include not only grade, but also species (birch, oak, maple, cherry, etc.)and thickness. If you don't intend to reveal any of the decorative plywood surface, I would recommend a standard construction grade 1/2" or 3/4" softwood plywood panel readily available at all home centers.

For an installation near the beach in Hawaii - will the product perform well in extermely humid condotions?

Classic Core – performance and durability in humid conditions Q# 1866 / Submitted 7/11/2007

On the surface, this would seem to be a yes or no type question, but it is a little more complicated than that. Classic Core should perform well under circumstances where any engineered wood product would be expected to perform. Products such as furniture, cabinets, or fixtures constructed of MDF or particleboard typically used in environments as you describe normally perform well as long as they are under reasonably controlled conditions. No wood product designed for interior use will perform satisfactorily under conditions of extremes of wet or dry conditions for prolonged periods of time. Hope this helps.<br /><br />Ang

We are looking for a small number of sheets of 3/8 inch veneer core PUREBOND plywood for construction of our kitchen cabinets. We live in Ottawa, Ontario, Canada and have tried the suppliers you suggest (ie. MacFaddens Hardwoods and Home Depot). Neither carry this item in stock, so we would have to order and pay for a minimum of 36 sheets, which is far too much. Where is the nearest supplier who will actually sell us this product in reasonable amounts??? How can we obtain it? I sent in a question before and didn't receive any answer, so please respond this time!!!

3/8 inch pure bond veneer core plywood Q# 1860 / Submitted 7/5/2007

I apologize for the inconvenience you are experiencing. We currently have our field sales rep for the Ontario market checking for a distributor who carries 3/8" veneer core plywood, but this could take a little time. For the record, 3/8" in any construction is not as common as one might think, and most dealers and lumber yards do not carry it. It is somewhat more common for large distributors with large OEM accounts, but these are usually highly specked for the individual customer who buys them in full bundle or greater quantities. You have also not indicated the species you are seeking. Birch and maple are the typical species considered to be paintable, and these should be a little easier to locate in smaller quantities in 1/2" thickness, which you may find a little more readily available. However, it probably won't make the search for 3/8" any easier. <br /><br />We manufacture about 70,000 plywood panels in a wide variety of constructions, species, and grades to distributor or OEM specifications every day in North America in large capacity presses. Unfortunately, unless one of our distributors in your area routinely carries items like 3/8

Is NAF plywood avalibale in China ? Thank you

NAF plywood Q# 1857 / Submitted 7/4/2007

NAF means "no added formaldehyde" and typically is used to indicate no added "urea"-formaldehyde. If you are asking about our PureBond products, they are not currently available in China. However, no added formaldehyde panels are likely available in localized markets, but you will need to know the market and the producers in order to obtain more accurate information. NAF panels may be manufactured with a variety of adhesives other than our PureBond offerings. These include the MDI family, phenolics, and PVA's to name a few. Hope this helps!<br /><br />Ang

Plywood came in to our plant with "Termite Treated" stamped on the 3/4' plywood. I cannot find any info on the MSDS concerning termite treatment. Can you please explain? Thanks

Termite Treated Q# 1853 / Submitted 6/21/2007

Consensus in our company is that the plywood itself is not likely treated, especially if it is domestic production. Quite often with imported panels, the crating is treated if it is green to satisfy reuqirements of the Department of Agriculture. If this is the case, there would not be any indication of the treatment in the MSDS. We would appreciate any follow-up to indicate from whom you purchased the material, and during what time frame so that we may investigate a little further. <br /><br />Ang

What is the difference between veneer core and composite core?

veneer core vs composite core Q# 1846 / Submitted 6/8/2007

Generally speaking, veneer core means all the components of the plywood panel are pieces of wood "peeled" from various logs and placed one on top of the other alternating a 4 ft wide by 8 ft long layer over an 8 ft wide by 4 ft long layer. There are usually an odd number of plies, with the inner plies being thicker and cut from abundant species with lackluster character, and the two outer plies (face and back) being much thinner, cut from the more decorative hardwood or softwood species of choice. From the edge, the product looks much like common construction plywood, such as CDX. Composite core usually means the face and back are bonded to medium density fiber board, a material consisting of wood fibers generally derived from post industrial use (saw dust and planer shavings) and glue, or particle board consisting of wood chips from similar sources bonded together with glue. These products are also referred to as engineered core. Hope this helps.<br /><br />Thanks for a great question.<br /><br />Ang

I'm considering using 4x8 sheets of plywood as flooring. Do you have a hardwood species you would recommend, and how would you attach it and finish it?<br /><br />Thanks so much for any info you can give me!

Plywood as flooring Q# 1838 / Submitted 5/30/2007

Honestly, I wouldn't recommend using plywood for flooring. Engineered wood flooring is manufactured in a similar manner to plywood, but is further processed into lumber sized strips and finished with a very durable coating suitable for traffic. Plywood will have an extremely thin face veneer that is just not suited for floor traffic, whereas engineered flooring will have a very thick outer layer of the species chosen. The combination of thicker outer veneer and durable finish makes engineered flooring a much better choice. It is more expensive on the front end, but it is easy to install and since it is already finished will save up to a week in finishing time when you consider pre-sanding, sealing, and sanding between coats until a desirable finish is achieved, and then the finish you apply on-site will never achieve the durability of the factory applied finish.<br /><br />For more information, you may wish to contact our flooring division at www.columbiaflooring.com or toll free at 800-654-8796.<br /><br />Thank you for your interest in Columbia Forest Products.<br /><br />Ang<br />



I have recently been considering two things. building a kayak with meranti marine plywood, and redoing my bathroom. I had the idea of using plywood with a clear epoxy coating to be used as a shower surround. so my questions would be... if given a couple of layers of epoxy on both sides, would regular plywood be able to stand up to being in a shower surround or I am right to think that marine ply is the only way to go. Is there something I am missing where putting on epoxy would still have problems with the heat and moisture of the shower?<br /><br />Thank you very much,<br />Gene Gilbert

Plywood in a shower Q# 1837 / Submitted 5/30/2007

To begin, meranti is not available in marine grade. This is a commonly mislabled product that may be used in certain restricted marine applications, but marine grade is a designation sanctioned by the American Plywood Association covering panels manufactured with specific softwood componenets and adhesive systems. Having said that, I think you will be asking for problems if you try to use plywood for a shower stall exposed surface. It may hold up for a while if you cover it completely on all surfaces with epoxy or fiberglass, but eventually the relentless exposure to heated water, soap, steam, drying, and cleaning agents will start to erode the finish to the point it will start to crack, resulting in water penetration that will stain badly and be a hotbed for mold to develop. For a kayak, I would avoid over the counter meranti, and even if you choose marine grade softwood plywood, you will still need to totally enclose all components with fiberglass or epoxy. I have still seen evidence where constant beating with rough water, rocks, and logs have damaged the finish in short order to the extent the wood starts to absorb water, resulting in significant repairs or replacement. <br /><br />Sorry I couldn't have been more help.<br /><br />Ang

formaldehyde free Q# 1836 / Submitted 5/27/2007

For interior decorative panel products, our PureBond formaldehyde free panels will meet your requirements. Be sure to specify formaldehyde free as we still use some urea formaldehyde bonded substrates where formaldehyde free options are non-existant. This will help our distributor/dealer communicate your needs to us. With regards to other building materials, there are formaldehyde free products such as Johns-Manville insulation. Naturally, solid lumber for structural and decorative applications will be formaldehyde free to the extent any biological material can be, but for other products you will need to check with the various manufacturers to be certain.<br /><br />Thank you so much for your interest in our PureBond products.<br /><br />Ang

As a cabinet shop, can we use Pure Bond instead of standard wood glue? If so, how & where do we purchase this?

Pure Bond Glue Q# 1831 / Submitted 5/24/2007

We are not currently making our PureBond adhesives available to end users, but it is possible that we will in the future. Right now the product is mixed at our local just prior to use, and in that form it must be used in a very short time frame. However, we are working on developing a Ready-To-Use product that has a more practical shelf life. Thank you for your interest in our PureBond products!<br /><br />Ang

I am looking for a source of structural fir plywood that is formaldehyde-free & made from FSC woods.

formaldehyde-free fir plywood Q# 1828 / Submitted 5/22/2007

We are producers of decorative panel products as opposed to the softwood plywood panels you indicate you need. Structural panels are typically manufactured using a phenolic formaldehyde adhesive system, that while not technically formaldehyde free, does not emit formaldehyde in amounts considered unsafe by most regulatory agencies. As far as FSC wood from these sources, your best bet would be to check out the individual producers. The trade association to which these folks belong is the American Plywood Association at apawood.org. Or you can check out the various sites for producers such as Weyerhaeuser, Georgia-Pacific, or Plum Creek, to name a few.<br /><br />Hope this helps!<br /><br />Ang

which works better power nailer 200 or S97125 LHF

installing Q# 1823 / Submitted 5/15/2007

I am not familiar with the second nailer, but the first one you list is a very good one. However, you did not indicate what you are installing and in what application, so the question is difficult to answer. For panel installation thicker than 1/4", nailing, or even gluing and screwing is not the recommended method of attachment of panels to walls. Rather, a system of "Z" clips with gaps between the panels called reveals is the better method, and that works best with 3/4" panels. If you are installing end panels in cabinets or furniture, nailing with a power nailer in blind joints that have been glued works well to hold the joint until the glue dries, then the glue takes over for the life of the piece.<br /><br />

So why doesn't anyone stock basic 1" sheets of veneer core plywood with plain-sliced red oak veneer?

PureBond availability Q# 1821 / Submitted 5/10/2007

It is more an issue of economics and inventory management than anything else. The more common thicknesses are, as you know, quarter inch, half inch, and three-quarter inch, and the more common species and cuts are rotary cut birch, rotary cut oak, and rotary cut maple. Most distributors carry a well managed inventory of these items in a variety of core offerings, including veneer core, MDF, and particleboard. Plain sliced red oak is very common, but many distributors choose not to carry the plain sliced version due to demand levels in their market. Where the demand is higher, distributors may choose to stock the common thicknesses discussed above, but 1" or other less common thicknesses are typically not stocked for general consumption, but rather may be inventoried if they have an established customer using a predictable level with a commitment to continue using the material.<br /><br />If you have a demand for 1" Veneer Core PS Red Oak, you can certainly have it special ordered. There may be somewhat of a lead time and some requirement for minimum quantity, but it is certainly available. Please contact your distributor to discuss your needs and have them let us know how we can help.<br /><br />Thanks!<br /><br />Ang



I am hearing about formaldehyde, formaldehyde precursors, and phenolic glues. Understand your soy product not avail in ME.Need a none-off-gassing ply product for damp basement flooring so can be habitable.

plywood glue Q# 1820 / Submitted 5/10/2007

Our PureBond plywood is now available through all our distribution lines. I am not sure why you have been unable to locate it in Maine, but I know it is readily available down east. You may want to do a dealer search through our dealer locator on our website to locate the nearest one to you.<br /><br />As for your basement, a phenolic bonded structural plywood product is probably your best bet. Phenolic does not off-gas at the levels of urea formaledhyde, and as an adhesive, it is water proof, rather than water resistant. It is recommended for high moisture applications whereas our PureBond or any other hardwood or decorative softwood product is recommended for interior, lower moisture applications.<br />Hope this helps.<br /><br />Ang



I would like to try your complany's pre-finished product on an upcoming kitchen cabinet project. Looking through just about all posted questions I did not find what I was looking for. I would like to know the basic process in using this product as far as adding solid wood to it, scratches, damage, etc.. I understand that the pre-finish is not something commercially available, nor does it seem to take other finishes. So if I want to add solid wood mounting rails in a cabinet or edgebanding to a shelf; how is this done with professional results? What is the closest clear film finish that is compatible with your complany's propreitry blend? <br /><br />Many thanks,<br /><br />Jean-Christophe Hartman

Working with UV finished ply Q# 1818 / Submitted 5/10/2007

UV cured finishes offer many advantages as you can imagine. However, they are not necessarily suitable to all applications. Typically, they are used for cabinet interiors, or for shelving or frameless cabinets where a matching edgebanding will provide satisfactory results. They are extremely durable as the finish is actually a 100% solids material cured with exposure to ultra violet light waves during the finish process. While not impervious to damage, the finish is highly resistant to scratches, cleaning materials, and even most solvents. It is not well suited to using a solid wood edgebanding that must subsequently be finished to match. While polyurethane, conversion varnishes, or even nitrocellulose lacquers can be used on the solid to provide satisfactory finishes, they must be applied with meticulous care, and the results may vary.<br /><br />Your best bet in finding a source for our UVWood is to contact one of our distributors through our dealer locator on our website. While we don't make a prefinished edgebanding, many of our distributors carry a line of edgebanding, so be sure to inquire about the availabilty of both UVWood and edgebanding. <br /><br />Best of luck with your search, and thank you so much for your interest in our UV finished panels!<br /><br />Ang



Could you please confirm that your maple plywood is being manufactured with Purebond adhesive?<br />If not, is it phenolic?

Maple Plywood Q# 1816 / Submitted 5/9/2007

We are currently in the final phase of converting our glue to PureBond in all our locations. For the most part, this has been completed for our veneer core panels, but there could still be a small possibility for the glue to be urea formaldehyde. We do not use phenolic formaldehyde adhesives to manufacture decorative panels at all. Another consideration: we do use our PureBond adhesive to bond faces and backs to engineered substrates (MDF and particleboard) but the core itself will still be produced by others using urea formaldehyde at this time.<br /><br />For now, I would recommend that you contact your distributor/dealer and specify PureBond for all your veneer core needs to ensure that your needs are met.<br /><br />Thank you so much for your interest in our PureBond offerings.<br /><br />Ang



Is walnut available in a "Rotary Cut" and if so is it available in 1/4" Ply.I am looking to eliminate the book matched appearance found in plain sliced..<br /><br />Strine Woodworking

Walnut Q# 1815 / Submitted 5/9/2007

Never say never in this business, but I know of no one rotary cutting walnut, and honestly don't recall seeing it over my 28 years in the industry. That doesn't mean someone out there isn't cutting it, but it would be very hard to find. An easier, but somewhat more expensive option may be to specify from your current supplier a plank or random match where the face will consist of various sized components carefully selected and spliced from several logs, giving it more of a solid wood look, and thus avoiding the book matched look. Even with the potential upcharge, your cost per job won't be impacted that greatly, and the fact that you will be offering something so unique should be a selling feature. Hope this hleps!<br /><br />Ang



I am making a sign for a green products supplier, and want to use your formaldehyde free plywood for part of it. It will be stained with a translucent VOC free latex paint from Rodda. What product do you recommend, and are there any finishing methods I should follow?<br /><br />Mardeen Gordon

using purebond plywood in a sign Q# 1814 / Submitted 5/8/2007

Our PureBond products may be fabricated and finished in any manner suitable for use with conventional decorative plywood. We have not found any finish issues that would require special attention. I would suggest checking with the finish supplier for their recommended methods and procedures for application. My only concern is that PureBond, or any of the other commonly available decorative panel product, is not intended for use in exterior applications, but if your sign is intended for interior use, you should see no differences in how the panels should be treated. Thank you so much for your commitment to the environment!<br /><br />Ang



what is the difference between solid cherry wood and cherry plywood as far as strength and duribility for the back of furniture?

cherry wood Q# 1813 / Submitted 5/7/2007

Without trying to sound too technical, wood is an anisotropic material. That is to say it has different properties in different directions. For example, wood has considerably more strength across the grain as opposed to parallel to the grain. Additionally, moisture movement will have a greater effect across the grain as opposed to along the grain. Veneer core plywood in effect counters these differences in that every other component in the "sandwich" that makes up the panel is oriented with the grain at a right angle to that of the adjacent components. This actually means the physical properties relative to strength are improved in plywood over solid wood, and thus would mean plywood is a highly acceptable option for use as backs of furniture.<br /><br />Thanks for a great question!<br /><br />Ang

Hi,<br />I am looking for cabinet makers that make standard size "off the shelf" cabinets that use your PureBond material. Can you help me with a list?<br />Thank You, <br />Emily McGlohn

standard cabinets Q# 1809 / Submitted 5/2/2007

We actually do not have such a list. We sell hundreds of distributors across North America who re-sell to hundreds more cabinet manufacturers in addition to the limited number of cabinet manufacturers we sell direct. All of them are now receiving our PureBond panel products, so you shouldn't have too much trouble locating one. Most of the manufacturers produce to order today, so you may not locate one who has a stock line, but getting cabinets manufactured with PureBond should not be a problem. I would suggest contacting your local cabinet dealers to see if any of their lines they offer are utilizing Columbia's PureBond panel products. Thank you so much for your interest in our PureBond line!<br /><br />Ang



I would like to know where I can find humidity expansion rates, compression resistance, axial compression rates etc. for "purebond" plywood<br /><br /> Thanks<br /> Andy

Specific properties Q# 1808 / Submitted 5/2/2007

The values you mention are not frequently requested for decorative products such as hardwood plywood, but compression tests such as the Janka Ball test are sometimes used by cabinet manufacturers and and architectural woodworkers and may be available from their respective trade associations. Hardwood and decorative softwood panel products are marketed and sold as interior decorative panel products and not for their engineering properties as are their softwood structural counterparts. Linear expansion values are a part of the standard for engineered panel products such as particle board or medium density fiber board, and these are sometimes transposed to hardwood plywood manufactured with these products as the substrate, although the hardwood plywood standard does not address them. Regardless of bonding agent, these values are listed as 0.35% for particleboard and 0.3% for MDF. With respect to PureBond panels, only the adhesive has changed, so the properties should not vary dramatically from traditionally manufactured hardwood panel products for which you may already have values. In testing we are required to do, such as bond line performance in accordance with HPVA/HP-1-2004, Section 4.6, Three-Cycle Soak test, PureBond panels pass with no issues. Hope this helps.<br /><br />Ang

I am designing and building a cat habitat. My prototype features Medex (an SDF) with lap joints. Can the Purebond plywood be cut for lap joints? Is there a core that better suited for lap joints, i.e. wheatboard core. Or will there be a greater risk of chipping, as the veneer seems somewhat thin? Also, the samples I received look like finished flooring. I assume that the sheets are unfinished. Is that correct? Thanks for your input. I am excited about the idea of using your product.

Lap joints and Purebond Plywood Q# 1806 / Submitted 4/30/2007

Lap joints should not present a problem, but my concern is using any of our products to replace a Medex product. Medex is designed and manufactured for exterior applications, whereas our wide variety of construction combinations making up our PureBond panel product line are intended for interior decorative applications such as cabinets and furniture. I am not familiar with the samples you received, so unfortunately I am not in a position to address that. We do provide panels pre-finished if so ordered, but otherwise provide our panels unfinished. We also manufacture pre-finished solid wood and engineered flooring in a separate division, as well. Thank you so much for your iterest in our PureBond products.<br /><br />Ang

Could you please clarify if you sell laminated flooring? If so, do you sell laminated flooring made with PureBond? I am looking for formaldehyde free laminated flooring; is there such a thing yet? If not, do you plan to roll-out something like this, as you have already done for formaldehyde free plywood and particleboard? Lastly, are you also producing formaldehyde free (PureBond) MDF and if not yet, will you be? Thanks.

laminated flooring etc. Q# 1804 / Submitted 4/27/2007

We manufacture a line of PureBond engineered flooring, which is 3 or 5 plies of wood veneer, topped off with a given species such as oak, maple, cherry, etc. This flooring type is all wood, but not solid wood, and, because it consists of multiple components glued together, it is sometimes erroneously called laminate flooring. Laminate flooring is actually an MDF product overlaid with a high pressure laminate or plastic surface designed to replicate natural wood, stone, tile, or the like. We do not currently manufacture that product with the PureBond adhesive. Hope this helps!<br /><br />Ang

I am located in the Boston Area and I have a business making store fixtures. I made some custom store fixtures for a market that wanted a 48" wide cabinet with a 46" long shelf out of Columbia Oak Plywood that i purchase at the Home Depot.<br /><br />I have a rabitted 1x2-46" piece of Oak glued and braded to the edge of the plywood as a stabilizer to the front of the shelf and the shelves are all sagging from 1/16" to alomst 1/4" in the center of the shelves.<br /><br />Could the plywood be warpping and causing the shelves all to sag?<br /><br />JB

Sagging Shelves Q# 1800 / Submitted 4/25/2007

It is always difficult to diagnose a condition without having an opportunity to examine the wood, itself, but if the deflection is occurring with no load, then warpage is a consideration. You have properly designed the shelves to include fasteners, but you did not indicate if they were supported on both ends and the center in the back, which could help under maximum recommended load conditions. The Architectural Woodworkers Institute (awi.org) published information relative to shelf span that may be useful in this and future situations.<br /><br />If the deflection is due to warp, there could be a number of variables at work, including moisture content, equilibrium moisture content, and the construction of the panel, to name a small list. This makes it difficult to precisely determine the cause.<br /><br />Sorry I couldn't be of more assistance.<br /><br />Ang

MDF Fire Rating Q# 1799 / Submitted 4/25/2007

A1 purebond 4×8 Q# 1797 / Submitted 4/24/2007

There is actually a great deal of variation in the weights of the various constructions of 3/4" Veneer Core panels we produce, depending mostly on location. Panels we produce on the western US are typically softwood innerplies, and will weigh from 50 to 60 pounds. Our eastern US production is usually manufactured with yellow poplar (Tulip wood) innerplies, and will weigh between 65 and 75 pounds. Our Canadian plant utilizes Aspen for innerplies, with a weight range around 55-60 pounds. We do not have a construction for a 3/4" veneer core that would be expected to weigh under 50 pounds routinely. Hope this helps.<br /><br />Ang
