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

By minimizing air and water vapor flow through the building exterior, PERM-A-BARRIER® Aluminum Wall Membranes prevent premature deterioration of the building envelope, enhance thermal performance of the structure and save energy costs and improve comfort for the building occupants.

Features

• Fire resistant - meets NFPA 285 as part of various wall assemblies with foam plastic insulation
• Fully bonded - transmits wind loads directly to the substrate
• Waterproof and virtually impermeable to moisture - virtually impermeable to the passage of liquid water and vapor
• Air tight - protects against air passage and associated energy losses. Meets new ASTM E2357 standard as required by IECC 2012
• Aluminum faced film - provides extended UV exposure, improved sealant adhesion to film, dimensional stability, high tear strength, puncture and impact resistance
• 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® Aluminum Wall Membrane surface and ambient temperatures at 5°C (40°F) and above; PERM-A-BARRIER® Low Temperature Aluminum Wall Membrane surface and ambient temperatures between 25°F (-4°C) and 60°F (16°C)
