Great Stuff Pestblock Insulating Foam Sealant

Great Stuff Pestblock Insulating Foam Sealant is an expanding polyurethane foam specifically formulated to seal gaps, cracks, and openings that allow pests to enter your home. Designed for both indoor and outdoor use, this durable foam forms a long-lasting, airtight, and water-resistant barrier that not only blocks insects, mice, and other pests but also improves energy efficiency. Once applied, the foam expands to fill voids up to 1 inch wide, hardening into a strong, closed-cell structure that resists moisture and air infiltration. Its advanced formula includes a special ingredient that naturally deters pests without using harmful chemicals. Ideal for sealing around pipes, vents, eaves, attics, foundations, and utility penetrations, Pestblock also helps prevent drafts and moisture buildup. After curing, it can be trimmed, sanded, painted, or stained for a clean finish. Perfect for homeowners seeking long-term protection and comfort, Great Stuff Pestblock is the ultimate solution for pest-resistant insulation and gap sealing.
