Formaldehyde

Formaldehyde is emitted from wood under very high heat and is thankfully nothing to worry about, as any possible emissions will have dissipated by the time the lumber reaches suppliers. 


The emission levels of formaldehyde depend on factors such as wood species, moisture content, outside temperature, and time of storage. 


Formaldehyde is an integral part in plywood manufacturing. Since ply is one of the most popular building materials around, it would be difficult to avoid using it.

The formaldehyde emissions from plywood tend to be at their highest immediately after the manufacturing process. This is when timber sheets are bonded together using phenol formaldehyde adhesive. 


However, the formaldehyde emissions do eventually subside after a few weeks. Manufacturers also apply phenolic coating to plywood to help lower emission levels even further.


By the time the product reaches your plywood supplier, their formaldehyde emissions will will have become close to negligible.

Luckily there is nothing to worry about, but it's good to be in the know!
