GREAT STUFF Window and Door Insulating Foam Sealant is a minimal-expanding, low pressure-build polyurethane foam designed to provide a weather-tight seal. It is proven not to bow or distort window and door frame openings, when properly applied. It can also be used for sealing areas where low-pressure, flexible foam is desirable. If you're installing windows, doors, or skylights and you're not using GREAT STUFF Window and Door Foam Sealant, you're probably unaware of a faster, cheaper, air-sealing solution.
