20OZ WND - DR FM SEALANT

Great Stuff Pro Window & Door Insulating Foam Sealant is a one-component, minimal-expanding, low pressure-build, flexible polyurethane foam. It is exclusively formulated to air seal the gap between a window or door frame and the rough opening. The foam expands only enough to generate an effective seal. When applied properly, the sealant is proven not to distort or bow window and door frames. Designed to form a durable, airtight, water-resistant bond to vinyl, wood and metal surfaces. The foam skin repels and deflects water, which helps reduce the potential for moisture damage in frame openings. Sandable and paintable. Reusable straw applicator included.
