Help identifying off-gassing from spray foam insulation
Our Demilec Agribalance open cell polyurethane spray foam insulation has been off-gassing a smell since it was applied 7 months ago. Before I move my family back into the house I’d like to know what’s coming from the foam, especially since Demilec lists a safe exposure level for their amine catalyst (a likely cause of the smell) at only 0.05ppm.
Demilec has offered to foot the bill for air quality testing, but only for specific tests that can’t detect amines. (I went to them first since they’re the experts in their own proprietary chemistry; although they acknowledge there’s a smell coming from our foam and that it’s a familiar smell to them, they won’t identify it for us. They’ve also “lost” the first foam sample they took from our house and reneged on a promised chemical analysis of the second sample, and they’ve bounced us around to three different people for months. Overall thus far they’ve been less than helpful.)
No test labs or industrial hygienists I’ve spoken with to date have a way to test for unspecified chemicals, particularly amines. I understand that this is more difficult than routine tests. I think at this point I need someone with more specific knowledge & experience: I’m looking for a recommendation to someone—a lab or consultant—who’s successfully identified chemicals off-gassing from spray foam.
