Durable material This sealing tape combines selfadhesive polymer modified asphalt with an aluminum foil backing. It is thick and sticky, resists shrinking, and is designed to be antiaging, heatinsulating, strong, and durable. It provides reliable sealing to help prevent leaks with a simple stickon application. Multifunctional performance The aluminum back film reflects sunlight, contributing to a cooling effect. The tape delivers effective sealing, waterproofing, thermal insulation, and flame retardant properties, helping to protect and insulate surfaces in a range of conditions. Energy efficiency and winter readiness The aluminum insulating film helps keep cold air out and warm air in during colder months, supporting longerlasting indoor warmth. This can reduce the energy required for heating and lower operating costs over time. Wide compatibility and versatility Suitable for a variety of weather conditions and a broad range of surfaces. It performs well on metal, tiles, shingle, aluminum, galvanized steel, gypsum board, wood, fiberglass, brick, concrete, and more. A practical tool for home, auto, and outdoor applications. Use scenarios Roof seams, gutters, and exterior joints: seal and waterproof to prevent leaks and improve insulation. Ducts, pipes, and exterior walls: seal and insulate to reduce air leaks and heat transfer. Automotive and outdoor equipment: weatherproof panels, trim, and joints to protect against moisture and temperature fluctuations.
