Durable material for roof insulation and waterproofing: an asphalt based membrane with a thickened PET foil, coated with aluminum foil. It is thick, adhesive, flexible, and lightweight, with no shrinkage. It provides anti UV and anti aging performance, is flame retardant, offers heat insulation, moisture resistance, and waterproofing, and has strong adhesion. Self adhesive installation: designed with a selfadhesive backing that can be pasted directly. It forms a strong bond and is not easy to peel off after application. Safe and durable performance: adhesive and sealing force with a long service life. No water seepage and no shrinkage. tensile strength and aging resistance. Odorless, good heat resistance and cold resistance, water resistance, and strong environmental adaptability. Suitable for use in both hot and cold climates. Multifunctional barrier and protection: the aluminum foil back film reflects sunlight, providing a cooling effect. It offers reliable sealing, waterproofing, heat insulation, flame retardancy, and isolation. It serves as a durable barrier, resistant to shrinkage, deformation, and cracks, forming a long term non deformable waterproof layer to prevent water penetration. Applications and use scenarios: 1) Roof construction and renovation on residential or commercial buildings for waterproofing and insulation. 2) Basement or foundation waterproofing and moisture control in damp environments. 3) Exterior walls, terraces, and balconies where UV protection, waterproofing, and thermal insulation are required.
