Improved Title: Great Stuff PRO Insulating Foam Sealant for Gaps & Cracks, 24 oz

GREAT STUFF Gaps & Cracks is a polyurethane-based insulating foam sealant that effectively fills, air-seals and insulates small gaps (up to 1 inch) both indoors and outdoors. As the name suggests, it is great at what it does. What you may not have known is how effortless it is to apply (thanks to the straw applicator) and how it expands to perfectly fit the shape of cracks and voids, creating a strong, airtight, and water-resistant bond that eliminates unwanted airflow and helps reduce condensation. It is essential to use it with the GREAT STUFF PRO Series Dispensing Gun.

In addition to its insulating properties, it is also recognized as a fireblock, meaning it inhibits the spread of smoke and flames through concealed spaces. It expands minimally, making it suitable for general purpose building envelope air sealing. It has the capacity to fill gaps up to 3 inches and expands to fill the shape of cracks and voids. Once cured, it forms a permanent, airtight, and water-resistant bond to vinyl, wood, and metal surfaces. Great for use both indoors and outdoors.

The ease of application and the effectiveness of GREAT STUFF Gaps & Cracks make it an ideal choice for addressing insulation and air sealing needs in both residential and commercial environments. With its ability to create a durable and reliable seal, it helps improve energy efficiency and indoor comfort while also providing protection against fire hazards. Plus, its versatility in bonding to various surfaces makes it a valuable addition to any building or renovation project. For all your small gap sealing needs, GREAT STUFF Gaps & Cracks is the reliable solution.
