[Greenbuilding] formaldehyde-free ply wood

[Irina Golfman]

Hello everyone,

I hope that someone can clarify my confusion and help me locate 
formaldehyde-free plywood.

I now understand that there are two types of formaldehyde. The 
urea-formaldehyde (really toxic) and phenol-formaldehyde (less toxic). I am 
told that while certified urea-formaldehyde plywood is available, plywood 
that is free of both types of formaldehyde does not exist.

I was told previously that CDX plywood (also knows as outdoor grade) is 
free of formaldehyde (both kinds?). However, someone just told me that this 
is not always the case.

I am working with my contractor to locate the plywood that would work for 
my healthy house and would very much appreciate any help that the folks on 
this list can give me.

Many thanks,
