Perm-A-Barrier Wall Membrane


  • 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
  • Coverage Rate – See page 6 of the Technical Data Sheet for the coverage chart
