DAP DraftStop 812 is a professional-grade, low-pressure polyurethane foam sealant specifically engineered for sealing gaps around window and door frames. This single-component, gun-grade formula expands minimally to create an airtight, weatherproof seal without exerting the excessive pressure that can warp or deflect delicate frames. The cured foam remains non-rigid and highly elastic, offering 30% joint movement capability to accommodate building settlement and thermal expansion. It features a closed-cell structure that effectively blocks moisture, air, and sound intrusion while providing a Class A fire-retardant barrier. Suitable for both interior and exterior applications, it adheres to common building materials including vinyl, aluminum, wood, and masonry.
