DAP No Warp is specially formulated for use around window and door frames. While it can be used as an all-purpose foam, this revolutionary 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. The end result is an air-tight seal around windows and doors to help lower energy costs.
FOR BEST RESULTS:
- Apply in temperatures between 60°F- 120°F
- Surface must be clean, dry, and free of all foreign material for adhesion
- Dispense in the UPSIDE-DOWN position
- Apply in spaces with 40% relative humidity or greater
- If used outdoors, paint to avoid foam discoloration
- Use around, not inside, junction boxes
USE TO FILL AND SEAL:
- Window and door frames / jambs
- Through-penetrations
- Gaps and cracks in foundations,
- crawlspaces, attics, and basements
- Partitions and stud walls
- Top and bottom of stair stringer
- Space connections in soffits and drop ceilings
