Home » Product Lines » Handi-Foam® Fireblock Low Pressure One-Component Polyurethane Foam Sealant (OCF)

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.

Handi-Foam Fireblock is UL GREENGUARD Gold certified contributing to healthier indoor environments.

Handi-Foam Fireblock is available in a variety of sizes and can be dispensed with a straw applicator or using a Handi-Tool® Dispensing Unit.
