Great Stuff 157860 Triple Expanding Foam Sealant is a high-performance, one-component polyurethane foam designed to fill, seal, and insulate gaps and cracks up to 1 inch. This professional-grade sealant expands to take the shape of voids, creating a permanent, airtight, and water-resistant bond that improves energy efficiency and blocks radon gas. It is ideal for sealing penetrations around pipes, ducts, and electrical outlets in attics, basements, and crawl spaces.
