Handi Foam® Fireblock low pressure one component polyurethane foam sealant is a moisture cured sealant designed to seal, fill, bond and stop air infiltration in areas where a fireblock product is required. Handi Foam Fireblock has a recognizable orange color allowing inspectors to easily identify the use of an approved fireblock product for Type V residential construction.

Due to its expansion characteristics, Handi Foam Fireblock is more effective than many traditional fireblocking materials for the blocking of flames and smoke in concealed penetrations, preventing flame spread from room to room and floor to floor.
