It is difficult to gauge how often spray polyurethane foam leads to the kinds of problems experienced by Keri Rimel and her family. I compiled dozens of reports of families experiencing problems with spray foam, from Robert and Cynthia Gibson in Florida to a report of 40 people in the Netherlands who suffer from chemical sensitization after living in homes with spray foam.

Robert and Cynthia Gibson launched a nationwide class action in the Middle District of Florida, the ninth such suit targeting spray foam insulation makers and installers over alleged respiratory and neurological injuries caused by the products.
