Dow ProductsGREAT 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.(1) Once cured, it remains soft and flexible, permitting natural expansion and contraction of surrounding surfaces. GREAT STUFF PRO™ Gaps & Cracks helps prevent drafts and repel water, helping enhance energy efficiency and improve occupant comfort.

For window and door framework, minimal-expanding GREAT STUFF PRO™ Window & Door Insulating Foam Sealant is proven not to distort or bow the framework, when properly applied.

Comes with straw applicator. No applicator gun needed
