Aluminum Glass Cloth Facing is a type of specialized insulation material used for various applications, particularly in the construction, HVAC industries. This insulation facing is often used in conjunction with insulation materials such as fiberglass or mineral wool to create a thermal barrier in buildings, HVAC ductwork, and other applications where thermal insulation and moisture control are important.
The aluminum foil layer provides excellent heat resistance, making it suitable for high-temperature applications, and acts as a moisture barrier, preventing water and air from passing through. The adhesive coating ensures a strong bond to various surfaces, including metal, wood, and plastic. The glass cloth fabric adds strength and durability to the tape, making it resistant to tears and punctures.
