Handi-Foam® Fireblock West low pressure one-component polyurethane foam sealant is a moisture cured sealant designed to seal, fill, bond and stop air infiltration in areas with high temperature and low humidity climates. Handi-Foam Fireblock West 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 West 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.
Handi-Foam Fireblock West is UL GREENGUARD® Gold certified contributing to healthier indoor environments and complies with AAMA Doc. 812 for a low-pressure build that will not bow or distort windows and doors. Handi-Foam Fireblock West is available in gun foam and can be dispensed using a Handi-Tool® Dispensing Unit.
