Great Stuff 20 oz. Window and Door Foam Sealant

Great Stuff 20 oz. Window and Door Foam Sealant is formulated to air-seal gaps around window and door frames and rough openings. It expands to take the shape of cracks and voids, creating an effective barrier that helps stop drafts and reduce pathways where insects can enter. Designed to form a durable, airtight, and water-resistant bond to vinyl, wood, and metal surfaces, this low-pressure build foam features a protective skin that repels and deflects water without bowing or bending window and door frames.
