What are the different types of aluminum foil facing materials?

Aluminum foil facing materials are used in construction and insulation to provide a barrier against air and moisture. The different types include: 1) Kraft paper facing, which is a strong, absorbent paper used for general purposes; 2) Glassine facing, a thin, glossy paper with good water resistance; 3) PE-coated facing, where a layer of polyethylene is applied for enhanced water resistance; 4) Aluminum foil facing, which is a thin layer of aluminum for superior barrier properties; 5) Silicone-treated glass fabric, offering high-temperature resistance and used in high-performance applications. Each type has unique properties affecting their use in various applications.
