W. R. Meadows AIR-SHIELD™

W. R. MEADOWS AIR-SHIELD™ is a high-performance, self-adhering air, vapor, and liquid moisture barrier engineered to protect buildings from air infiltration and water damage. Designed as a 40-mil thick, roll-applied membrane, AIR-SHIELD™ features cross-laminated polyethylene bonded to specially modified asphalt, creating a seamless, durable barrier that remains flexible and resilient under various environmental conditions.

Ideal for cavity walls, precast concrete, masonry, and exterior sheathing, AIR-SHIELD™ provides exceptional adhesion and puncture resistance, ensuring long-lasting performance against air leaks, water intrusion, and moisture vapor transfer. Its self-sealing capabilities around fasteners and compatibility with multiple substrates make it an essential solution for energy-efficient, weatherproof building envelopes.

Key Benefits of AIR-SHIELD™:

• Prevents air leakage and moisture infiltration—enhances building energy efficiency
• Self-adhering, roll-applied membrane—ensures seamless coverage
• Cross-laminated polyethylene film—offers high tensile strength, elongation, and tear resistance
• Flexible and durable—resists cracking, shrinking, and rotting
• Self-sealing around fasteners—reduces potential penetration points
• Puncture-resistant during installation—prevents damage to the air barrier system
• Compatible with multiple substrates—bonds to concrete, CMU, gypsum board, plywood, and metal
• Low permeability—controls vapor diffusion and condensation risk
• Easy to apply and cut to size—available in multiple widths

Common Applications:

• Air and vapor barrier for commercial and residential buildings
• Waterproofing protection for precast and cast-in-place concrete walls
• Moisture control in cavity walls, parapets, and firewalls
• Sealing sheathing panel seams, foundation sill plates, and window openings
• Air leakage prevention in high-performance building envelopes

💡 Available in rolls of 38.5″ x 75′. Custom-cut sizes available upon request.
