paulz Member	# Posted: 24 Sep 2017 11:10am Reply As a complete construction rookie, when I built my cabin 2 years ago I used OSB for the sheathing, walls and roof, the stuff is everywhere around here on track home developments. I still haven't finished the interior walls and you can smell it strongly when you first walk in. So I did a little reading about OSB and apparently formaldehyde is a bad thing to be breathing. Guess i better step up my game on the interior. I do get itchy eyes and plugged sinuses when I sleep there but it doesn't seem to bother my wife. Bad stuff eh?

It really depends on where it was manufactured and what the specs are for that factory producing a product. I think its nasty stuff. I have noticed it in a lot of the "cheap" click together laminate and MDF trims around here seem to have a lot of that stuff that will choke your sinuses up. It does take quite some time to off-gas, though I am unsure if it ever completely stops off-gasing. Hopefully you get the interior finished and it stops bothering you!
