Polyethylene Breathable Membrane Waterproof Vapor Barrier Membrane for Roofing Liner Packaging

High-Strength Polyethylene, Waterproof & Durable
Made from high-density polyethylene (HDPE) or polypropylene (PP)—excellent tensile strength and resistance to water infiltration for reliable structural protection.
Micro-Porous Breathable Design
Microscopic pores allow vapor transmission while blocking liquid water—prevents condensation inside insulation, maintaining a dry building envelope.
Lightweight & Flexible for Easy Installation
Soft and easy to cut, fit, and lay—conforms smoothly to curved or complex steel roofs and wall surfaces, speeding up on-site work.
Weather & Chemical Resistant
Withstands UV exposure, temperature extremes, and chemical corrosion—performs reliably in harsh outdoor environments over long periods.
Eco-Friendly & Versatile Application
Meets environmental standards, free of harmful emissions. Suitable for industrial plants, warehouses, stadiums, and other building insulation systems.
