This 3-in-1 aluminum laminated waterproof insulation membrane measures 1m wide by 10m long, integrates 3 functions of waterproofing, heat insulation and structural reinforcement. Adopting weather-resistant woven fabric combined with aluminum foil lamination technology, it features stable and tough structure: it can reflect radiant heat to reduce heat exchange between indoor and outdoor, block external heat intrusion in summer and lock indoor temperature in winter, effectively lowering energy consumption for temperature control; meanwhile it perfectly blocks moisture and water vapor penetration, protecting building walls, roofs, pipelines from moisture corrosion damage. This roll membrane is suitable for a wide range of scenarios including roof heat insulation, wall insulation, underfloor moisture proofing, carriage heat preservation, pipeline insulation and other home decoration and construction projects. It is easy to cut and install, and is a high-performance general protective insulation material for multiple scenarios.
