W.R. Meadows AIR-SHIELD™ Aluminum Sheet Membrane

AIR-SHIELD™ Aluminum Sheet Membrane is a high-performance, self-adhering air, vapor, and liquid moisture barrier designed to enhance energy efficiency and structural durability in commercial and residential buildings. This 40-mil thick, roll-applied membrane consists of a cross-laminated aluminum facer bonded to a rubberized asphalt adhesive, ensuring long-lasting adhesion, weather resistance, and puncture protection.

Ideal for cavity walls, precast concrete, cast-in-place concrete, masonry walls, and exterior sheathing, AIR-SHIELD Aluminum Sheet Membrane provides a continuous waterproof barrier that prevents air leaks, water penetration, and mold growth. It remains flexible at low temperatures, is self-sealing around fasteners, and offers UV exposure resistance for up to 12 months before being covered.
