GREAT STUFF PRO™ Gaps & Cracks
As the first foam sealant to be recognized as a fireblock, GREAT STUFF PRO™ Gaps & Cracks inhibits the spread of flames through concealed spaces. It’s a minimal-expanding, single component polyurethane foam sealant for general purpose building envelope air sealing. It fills gaps up to 3" (75 mm) and expands to take the shape of cracks and voids, forming a permanent, airtight and water-resistant bond to vinyl, wood and metal surfaces.
For cavities, cracks and penetrations larger than 3" (75 mm), Dow recommends FROTH-PAK™ Foam Sealant (US and Canada) or FROTH-PAK™ Foam Insulation (US only). 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.
