Great Stuff 12 oz. Window and Door Insulating Foam Sealant

Great Stuff 12 oz. Window and Door Insulating Foam Sealant is specially formulated for sealing around window and door frames. This minimal-expanding polyurethane foam expands with low pressure build and remains flexible and soft after curing, creating a reliable, weather-resistant barrier that will not bow framing materials when properly applied. Ideal for insulating and air-sealing drafty gaps, this foam adheres firmly to vinyl, wood, and metal surfaces. The cured foam provides superior insulation value compared to traditional fiberglass or caulk and can be easily stuffed back into openings without excessive trimming.
