The company offers No-Warp Foam, a one-component, polyurethane gun foam that’s specifically formulated for sealing gaps and cracks around window frames and door jambs. The low-pressure formula expands and fills to provide airtight insulation without exerting the force that could cause the frame to warp or bow and up to 90 percent less curing pressure than standard gun foams. The foam is a bright white foam that seals against drafts, moisture and insects, dries quickly and is easily trimmed. Available in a 20-ounce can that works with most foam applicator guns.
