Thermofoam fireblock sealant is a low pressure, 1 component, polyurethane foam sealant specifically designed and colored orange to seal annular spaces around ducts, plumbing penetrations, cables and other penetrations between rooms and floors. A critical advantage of Thermofoam fireblock sealant is its ease of use and its effectiveness at blocking smoke and toxic gases. The foam sealant stops air infiltration by blocking air from entering/escaping through gaps, which prevent the flames, smoke and gases from spreading. The product is for use in type V residential construction. Fireblock sealants are not intended for use in hourly rated assemblies.
