DAP No Warp Window and Door Foam Sealant is specially formulated for use around window and door frames. While it can also be used as an all purpose foam, No Warp is a revolutionary expanding polyurethane foam designed to air seal without exerting pressure that can be detrimental to window or door frame stability. DAP No Warp Foam Sealant low pressure foam is self venting which means that once it fills the void, the trapped gases leave the foam - unlike traditional polyurethane foam that may continue to expand and apply pressure. This makes DAP No Warp Foam ideal for sensitive areas like window and door frames. The end result is an air tight seal around windows and doors that lowers energy costs. Works on interior and exterior applications.
