GREAT STUFF Gaps and Cracks Insulating Foam Sealant with Quick Stop Straw Technology is a polyurethane-based insulating foam sealant that fills, air-seals and insulates small gaps (up to 1 in.) inside or out.

What's amazing is how easy it is to use, thanks to the Quick Stop Straw Technology, and how it expands to take the shape of cracks and voids. This forms a durable, airtight and water-resistant bond that eliminates unwanted airflow and helps reduce condensation.

  • GREAT STUFF gaps and cracks can be used in interior or exterior application and is tack free in 15 minutes; trims in 30-60 minutes
  • Forms a permanent weather-tight seal to minimize drafts and insect infestation and has exceptional adhesion to building materials
  • Cures as a cream-colored rigid foam; ease of application results from all-direction dispensing
  • One 16 oz. can equals up to 30 tubes (9 qt.) of caulk
  • Foam elasticity properties allow for movement and shifting within a structure
