Great Stuff Pro Series Window & Door Foam, 20 oz. quickly and cleanly fills, seals, and insulates around windows, doors, and their rough openings. This minimal-expanding polyurethane foam features a low-pressure build that helps lower energy bills by creating a durable, airtight, and water-resistant seal between a window or door frame and its rough opening. It is applied with a foam-dispensing gun for greater precision and easy access to hard-to-reach places. The can is reusable for up to 30 days, minimizing waste. The foam expands just enough to seal gaps without causing bowing or bending of the frame when applied properly. It bonds effectively to vinyl, wood, and metal frames, repels and deflects water, and fills 16 to 18 windows. The foam becomes tack- within 3 to 10 minutes and can be trimmed in one hour. After curing, it remains flexible and is paintable, stainable, and sandable, providing a versatile solution for window and door insulation needs. This product is equivalent to 13 quart tubes of caulk. Model Number: Great Stuff Pro Series Window & Door Foam, 20 oz.
