PERM-A-BARRIER® Wall Membranes are ideal for protecting the building superstructure from the damaging effects of the elements.

Features

• Fully bonded : Transmits wind loads directly to the substrate
• Waterproof and impermeable to moisture: Impermeable to the passage of liquid water and water vapor
• Airtight: Protects against air passage and associated energy losses. Meets new ASTM E2357 standard as required by IECC 2012
• Cross laminated film: Provides dimensional stability, high tear strength, puncture and impact resistance
• Cold applied: No flame hazard; self-adhesive overlaps ensure continuity
• Flexible: Accommodates minor settlement and shrinkage movement
• Controlled thickness: Factory made sheet ensures constant, non-variable site application
• Aggressive, conformable adhesive: Allows self-sealing around mechanical fasteners
• Wide application window: PERM-A-BARRIER® Wall Membrane surface and ambient temperatures at 5°C (40°F) and above
