Gaps & Cracks insulating foam is a UL classified polyurethane-based insulating foam that expands into openings & voids up to 1-inch to construct an air tight & weatherproof seal. Versatile for projects inside & out, this insulating foam has excellent adhesion to most building materials and is easy to use and apply with its attached straw applicator. There is no spray gun required. The cured foam can be trimmed, painted, sanded, and stained and is excellent for spot insulating and touch-ups. It is an excellent candidate for construction, electrical, industrial, & plumbing projects. Cured foam insulates to R-5 for each inch of foam.
