Handi-Foam® Fireblock Sealants are designed to seal, fill, bond and stop air infiltration. Handi-Foam is more effective than traditional fireblock materials at blocking flames and smoke. Fireblocking is required by the International Building Code for Type V residential construction. Additionally, Handi-Foam has proven to be more cost effective due to the ease of application and excellent yield rates than standard fiberglass and caulks. Handi-Foam Fireblock has a recognizable orange color allowing inspectors to easily identify the use of an approved fireblock product. Handi-Foam Fireblock West is available for climates with high temperatures and low humidity.
