INSULAT FOAM WNDW&DOOR 12OZ

GREAT STUFF Window & Door Insulating Foam Sealant is a low-pressure polyurethane expanding foam specifically engineered to seal the gap between window or door frames and their rough openings. It is designed to provide effective air sealing and insulation while avoiding excessive expansion pressure that could bow, warp, or distort window and door frames during installation.

This foam is formulated to expand just enough to fill irregular gaps and cavities around fenestration openings, creating a tight, durable seal that helps reduce air leakage, drafts, moisture intrusion, and energy loss. It is commonly used in new construction and remodeling projects where proper window and door installation requires controlled expansion and reliable sealing performance.

Once applied, the foam adheres to a wide range of building materials including wood, metal, masonry, glass, and most plastics. After curing, it forms a rigid closed-cell insulation barrier that helps improve thermal performance and overall building envelope efficiency. It can be trimmed once cured and is paintable, allowing it to blend cleanly with surrounding finishes for a more professional appearance.
Packaged in a 12-ounce aerosol can, this product is widely used by contractors and installers for sealing around window and door perimeters, improving energy efficiency, and ensuring long-term air and moisture control in residential and light commercial buildings.
