Vapor Barrier to Prevent off gassing of CCA treated wood and OSB ?
I am in the middle of house building for a passive solar designed house in a mild marine Climate in southern Chile ( similar to Portland Oregon) where likely using a vapor barrier would not cause problems from what I understand.
The house frame upper and lower floor was built with OSB which I understand contains formaldehyde and CCA pressure treated wood. These are common construction methods where I live.
In this case might someone recommend a vapor barrier to prevent off-gassing from the CCA wood and formaldehyde in the OSB ?
I know there was a great article recently posted https://www.greenbuildingadvisor.com/blogs/dept/musings/do-i-need-vapor-retarder
about vapor barriers but I thought I might ask the forum here also ..
Thanks in advance Im very new to housebuilding
