PERM-A-BARRIER® Aluminum Wall Membrane Data Sheet

PERM-A-BARRIER® 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® Wall Membranes: Prevent premature deterioration of the building envelope Enhance thermal performance of the structure and save energy costs Improve comfort for the building occupants 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
