Out-gassing of bad stuff from spray foam insulation
We are in design for a new home for a chemically sensitive family. It’s looking like the best approach for insulating this house will be spray foam to the underside of the roof deck, and treat the attic as part of AC space. However, my customer is concerned about the potential for the family breathing in bad stuff that gradually out-gases from the foam over time. I need to respond to that concern with specific information that is well backed up. I’m beginning my research with you guys. All advice welcome.
