TYTAN Professional Window & Door Insulating Foam Sealant is a cutting-edge, low-pressure, low-expansion foam designed to seal windows and doors with confidence. AAMA approved and engineered with innovative no-bow technology, it expands just enough to fill gaps with one application—without melting, shrinking, or bowing your windows. This aerosolized polyurethane foam not only provides more R-value per inch than traditional fiberglass insulation, reducing energy consumption, but it also delivers 20-50% more yield compared to the competition. ASTM E84 certified and AAMA/FGIA verified, it bonds securely to a wide range of construction materials including wood, metal, vinyl, masonry, glass, and most plastics, ensuring a water- and airtight seal. Ideal for sealing window and door frames, as well as filling spaces, cracks, and gaps, this foam also offers excellent thermal and acoustic insulation for both residential and commercial construction.
