Rigid Foam Smell
I just purchased recycled 40 PSI EPS foam that came off a commercial roof a few months ago. A few hours after stacking it in my garage, I could smell the foam. It reminded me of a sort of adhesive smell. There does not appear to be any adhesive on the foam.
It had set outside in the recyclers yard for 2 months before I picked it up.
I intend to encapsulate the crawlspace with this, but I’m afraid the smell will persist, even after covered with 1/4″ plywood (fire retarder). Is there something I can paint the foam with before putting down the plywood?
Is this normal for EPS foam (or any rigid foam) to have a smell?
