The Center for the Polyurethanes Industry (CPI) offers guidance to contractors and builders handing spray foam.

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.

Building Codes and Regulations

Spray foam is regulated through the model building codes and state and local governments. Model and local building codes are used throughout the United States to help make buildings safer for families and occupants by regulating design, construction practices, construction material quality, including fire performance, location, occupancy, and maintenance of buildings and structures. Building codes are updated and changed on a regular basis. Technical data sheets for spray foam products often indicate fire resistance ratings and compliance with stringent flammability code requirements.
