How do structural insulated panels react to fire?
Residential building code requires that foam insulation be separated from the interior of the building by a material that remains in place for at least 15 minutes of fire exposure. . Structural insulated panels faced with 0.5″ gypsum drywall meet this requirement. Commercial builders may need a one hour fire-rated wall or roof, which is achieved by testing and listing a specific wall or roof assembly to ASTM E119 with an accredited certification agency. Individual SIPA member manufacturers should be contacted to confirm listed assemblies they can provide.
