GREAT STUFF PRO™ Gaps & Cracks Insulating Foam Sealant is a minimal-expanding, single component polyurethane foam sealant for general purpose building envelope air sealing. As the first foam sealant to be recognized as a fireblock, GREAT STUFF PRO™ Gaps & Cracks resists the free passage of flames to other areas of the building through concealed spaces. Identifiable orange color.
Designed to fill gaps up to 3" (75 mm), GREAT STUFF PRO™ Gaps & Cracks Insulating Foam Sealant expands to take the shape of cracks and voids, forming a permanent, airtight and water-resistant bond to vinyl, wood and metal surfaces.
