GREAT STUFF™ insulating foam sealants expand to take the shape of the void and forms a permanent, airtight, and water-resistant bond that eliminates unwanted airflow and helps reduce condensation. It offers an outstanding air barrier while remaining soft and flexible, even after curing, which contributes to its superior product performance.

Designed exclusively for construction trade professionals, GREAT STUFF PRO polyurethane foam sealants offer the same dependability as the original GREAT STUFF product line, but feature reusable application tools, larger canisters and a wider range of temperatures at which the product can be applied.
