Is Spray Foam Insulation Flammable

Like many materials found in a home or building, spray foam can ignite and burn if exposed to a sufficient heat source. Foam insulation should be considered combustible and handled accordingly.

Is spray foam insulation a fire risk?

Icynene® spray foam insulation is a fire retardant, so it reduces the rate of flames spreading. Fact: in just 2 minutes a fire can become life-threatening. In 5-minutes, a house can become entirely engulfed in flames. Unlike other forms of insulation, it takes around 30 minutes for Icynene® to become flammable.

Is spray polyurethane foam flammable?

Although a fast and economical way to insulate, spray polyurethane foam (SPF), like most other organic materials, is combustible. SPFs will, when ignited, burn rapidly and produce intense heat, dense smoke and gases which are irritating, flammable and/or toxic.
