Handi-Foam straw foam sealants are designed to seal and fill small cracks, gaps and voids. Handi-Foam straw foam sealants are applied with an included straw applicator. Handi-Foam straw foam sealants are available in a variety of sizes to meet many application needs. This results in less waste on small jobs while having an economic impact on large jobs.

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 Sealants are the perfect choice for your sealing needs, and are available in Fireblock, black and standard formulations.
