PureBond is available in a wide range of real-wood face veneers, for great design versatility in DIY and professionally-built projects. Once you remove your existing floor and get down to the subfloor you’ll find concrete, plywood, oriented strand board (OSB) or solid wood slats. My issue is what your supplier told you about the NAUF plywood and the price that they quoted you. These panels are then laminated again to each other to create a multi-ply bamboo plywood with formaldehyde free emission. The Environmental Protection Agency (EPA) has launched research into the toxicity of formaldehyde as well.
I have a personal story of formaldehyde devastation in our home and lives: We bought our dream house, an 8yr old 4,000 sq ft with all upgrades we thought we wanted, two months ago. It requires knowledge of subfloor preparation such as: floor leveling, moisture conditions, pH levels, adhesive application and refinishing techniques—all of which are extremely complex, highly important and require professional advice. A typical plywood panel has face veneers of a higher grade than the core veneers. Once I found a house that seemed great in all other ways, I checked out possible sources of formaldehyde.
Under the Japanese Agricultural Standards (JAS), panels meeting the most stringent formaldehyde requirements (F★★★★) are required, using test method JIS A 1460, to have average emission levels below 0.30 mg/l. Chinese plywood has been shown to have among the highest levels of formaldehyde emissions. Examples 4 to 6 illustrate the specific examples using the combinations of three scrap plastics for the preparation of formaldehyde-free plywood.
MSDS: Reading the Material Safety Data Sheet (MSDS) is not enough because manufacturers don’t always divulge proprietary ingredients or toxic chemicals that amount to less than 1% of the total volume. Polypropylene (PP) scrap plastic film is prepared, which is used as a bonding material for the preparation of a 5-layer formaldehyde-free poplar plywood (5-mm thick). The insulation in their house is actually old denim, all of the plywood is formaldehyde free and even the paint they used is VOC free.
Structural plywood sold into Europe must meet EN 636 and be evaluated for formaldehyde based on EN 717-1. It’s also comparable in cost to traditionally manufactured hardwood plywood and comes in veneers from Alder to Walnut available at The Home Depot. OSB panels sold into European markets must meet the EN 300 standard and be rated for formaldehyde emissions based on the EN-717-1 test method using a formaldehyde test chamber. Bottom line, formaldehyde is toxic and should not have any easy way to get near my family or pets.
The formaldehyde-free plywood is prepared by firstly hot pressing the plywood mat and then cold pressing the same. Look for 100% FSC certified, formaldehyde free adhesives and zero VOC finishes. Plywood is a natural product that can be affected by changes in ambient weather conditions, possibly causing previously flat sheets to bow. As government and environmental agencies started discovering just how dangerous formaldehyde really is, regulations on the chemical became more stringent and all encompassing.
After thousands of dollars out of pocket, we learned the formaldehyde levels in our new house are dangerously high and toxic. Tropical plywood is widely used in the UK, Japan, United States, Taiwan, Korea, Dubai, and other countries worldwide. If she’s painting with a formaldehyde paint, and isn’t mixing in enough fresh air, she can be sick for several days. The research suggests that ventilating the units can greatly reduce formaldehyde levels. Either type of formaldehyde resin can be an issue when the product is in a minimally ventilated area. Particle board usually is found inside the house as it cannot handle moisture as well as plywood.
For its specific characteristic, formaldehyde free plywood is ušed especially for interior applications, where a great emphasis on a hygienic wholesomeness is laid – such as in hospitals, kindergartens etc. Working for a law firm I had a lot of unpleasant phone calls with sick people who lived in trailers built after Hurricane Katrina that reaked of formaldehyde. Completely formaldehyde free: this kind of plywood uses neither urea-formaldehyde nor phenol-formaldehyde.
Currently, the adhesives used in plywood and decorative plywood products in the market are mostly formaldehyde adhesives. I cannot tell you how much my life has changed since my husband became seriously affected by formaldehyde on the cabinets in our dream home”. The larger manufacturers and importers will just lobby to get loopholes and exceptions passed – that’s how it works with the EPA or any large federal regulatory agency. Fortunately, from what I’ve read, US companies have been implementing changes to decrease formaldehyde for a while now. Formaldehyde is typically more of an issue with engineered flooring than solid hardwood planks.
Disappointingly, Bunnings and some other large hardware chains choose to sell plywood manufactured in Asia, instead of Australia. The house didn’t contain enough of the chemical to smell it; that much I knew, as formaldehyde has a cloying smell and I would have been aware of it. I could have tested for formaldehyde (check online for test kits), but instead I looked for it: I figured that the more wood there was that had been glued together, the more formaldehyde. There are two common types of glues in plywood – one that contains phenolic-formaldehyde and one that contains urea-formaldehyde.
Yes, AFS/PEFC timber is now treated equally with regards to Green Star timber credits (refer media release by Green Building Council of Australia ). As plywood produced by Austral Plywoods is AFS/PEFC certified, you may be able to claim Green Star credits when using our products. Green building specifications often include preferences for wood products provided they are manufactured with adhesives with very low formaldehyde emission levels or are made with adhesives that do not include urea formaldehyde.
Colombia Forest Products has developed a soy-based (formaldeyde-free) adhesive used in plywood manufacture, and other companies are following suit. Unfortunately, big box stores like Home Depot and Lowes buy truckloads of no-name flooring and slap they own house brand name on it. There have been a lot of problems in the past with them doing this with flooring that they bring over from China that has either been harvested illegally or has had incorrect certification of chemical levels.
Columbia Forest Products (CFP) began developing formaldehyde-free plywood back in the early 2000s in order to make its sheet goods products comply with the United States Green Building Council’s LEEDS (Leadership in Energy & Environmental Design) Program. Formaldehyde can also cause — as it did for my relative — watery eyes, burning sensations in the eyes and throat, nausea and difficulty in breathing at elevated levels (above 0.1 parts per million). If you’re concerned with formaldehyde levels, you can always have the flooring in your home tested.
Both companies make products to the highest standards with either very little or zero formaldehyde; they use sustainable harvesting procedures, pay fair wages and recycle their waste efficiently. Formaldehyde emission tests (ASTM E-1333) conducted on APA Rated panels showed that their emissions were below 0.1 parts per million. Most notable is the British de Havilland Mosquito bomber, which was primarily made using a moulded sandwich of two layers of birch plywood around a balsa core.
There was formaldehyde in a bulletin board built onto the wall near a window in his office. The best part is that PureBond is competitively priced with traditional plywood making it an affordable option for families. You can also call a pallet manufacturer that does certified pallets and ask them if they will bake your plywood. In fact, many fruits and vegetables contain naturally occurring formaldehyde (see chart last page).
Perhaps the biggest shocker is the realization that formaldehyde is one of the main chemicals used for the embalming process in mortuaries. The bonding strength and water resistance therein cannot reach the requirements of Type I plywood. This formaldehyde regulation for wood panels is widely considered the most stringent in the world. Given their very low emissions, it can be inferred that APA Rated panels present exceedingly low potential for health problems due to formaldehyde exposure.
