The TYTAN TYTA0989 20-oz Extreme Climate Gun Grade Expanding Foam is a revolutionary one-component polyurethane foam engineered for optimal performance in extreme temperatures—from as low as 14°F (-10°C) up to 90°F. Specially formulated for both interior and exterior applications, this low-pressure foam is perfect for filling, insulating, and sealing gaps, cracks, and openings in buildings. Its ground-breaking “No Bow” technology and ability to cure in low humidity conditions make it ideal for dry climates and even for bonding to frozen materials. Offering a durable, airtight seal that stops cold air infiltration and minimizes heat loss, Extreme Climate not only saves energy but also provides a high insulating value while bonding effectively to common building materials such as wood, concrete, plaster, metal, masonry, and plastic. Environmentally friendly and UL classified, it’s a cost-effective solution designed to help you build with confidence, whether sealing around windows and doors or addressing penetrations in roofs, basements, and more.
