DAP NoWarp Window and Door Sealant

While it can be used as an all-purpose foam, Touch 'n Foam NoWarp Window & Door Sealant is specially formulated for use around window and door frames. This revolutionary expanding polyurethane foam is designed to seal and insulate 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 CO2 leaves the product – unlike conventional polyurethane foam that may continue to expand and apply pressure. This is ideal for sensitive areas (like window and door frames where the gap can be sealed without bowing the frame – even if the area is overfilled with foam). 

• Low pressure formula – guaranteed not to warp frames or jambs. 
• Fills and insulates better than fiberglass. 
• Stops drafts to minimize energy loss. 
• Creates a moisture barrier. 
• Fire retardant. 
• Meets ASTM E-84. 
• Bright white.
