GCP PERM-A-BARRIER WALL MEMBRANE 3FTX75FT

PERM-A-BARRIER Wall membranes prevent premature deterioration of the building envelope by minimizing air and water vapor flow through the building exterior.

Benefits and Features:

  • Fully bonded - transmits wind loads directly to substrate
  • Waterproof and impermeable to moisture - impermeable to the passage of liquid water and water vapor
  • Protects against air passage and associated energy losses. 
  • Meets new ASTM E2357 standard as required by IECC 2012
  • Provides dimensional stability, high tear strength, puncture and impact resistance
  • Cold applied and Flexible
  • Application surface and ambient temperatures at 5°C (40°F) and above
