Part 1

Losing their health and homes to spray polyurethane foam

A growing number of people are suffering from asthma and chemical sensitization due to spray foam insulation. In the introduction to this series, we meet Keri Rimel and her husband, who have both suffered from serious chemical sensitization after spray foam was installed in their new house.

When spray foam installation goes wrong, homeowners face a complex legal mess. However, a potential class-action lawsuit could shed light on how frequently spray foam fails.

Part 4

Spray foam insulation: Is it a fire hazard?

From toxic smoke to chemical combustion, spray foam poses dangers when it comes to fire. We look at how spray foam may act as a fire accelerant and how a sloppy installation job can generate enough to burst into flame.
