Prosource Window and Door Insulating Foam Sealant delivers high-yield coverage with a one-component polyurethane formula engineered for professional sealing and filling. Its moisture-resistant design expands to fill gaps, creating a durable, airtight, and water-resistant barrier. Ideal for sealing, filling, and insulating around windows and doors, as well as filling cracks, sealing roof voids, and tackling a wide range of construction projects. Available in both gun-type and straw-type dispensers for maximum application control.
