DAP® Touch 'n Foam® No Warp® is specially formulated for use around window and door frames. While it can be used as an all-purpose foam, this expanding polyurethane foam is designed to air seal without exerting pressure that can be detrimental to window or door frame stability. This low-pressure foam is actually 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). Ideal for sensitive areas like window and door frames. The end result is an air-tight seal around windows and doors that helps lower energy costs. 340 g.
