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.

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.

In fact, one 24 oz. can may replace up to 30 standard tubes of caulk. Handi-Foam Fireblock has a recognizable orange color allowing inspectors to easily identify the use of an approved fireblock product.


Handi-Foam Fireblock is available in both straw foam and gun foam dispensing systems. All Handi-Foam® Sealants cure when ambient
moisture/humidity in the air reacts with the foam sealant creating a rigid, closed cell barrier against draft, noise, moisture and air infiltration. Handi-Foam® Sealants are tack free within 10 minutes and meet ASTM E-84 Class 1 for caulk and sealants. Handi-Foam Fireblock is used to block the passage of flame and smoke in concealed penetrations from room to room and floor to floor in residential construction. Fireblocking is required by the International Building Code for Type V residential construction. It is not to be used as a firestop in commercial construction.
