Air- & Water-Resistive Barrier

  • Vapor permeable; moisture within the building enclosure can escape through the membrane via diffusion
  • Fully adhered to the substrate, no fasteners are required, eliminating leaks and improving the performance of the building enclosure with increased airtightness, making it ideal for energy-efficient construction
  • Lightweight and tear resistant, the membrane withstands the rigors of job sites, as well as tough wind and weather
  • Two outer layers are made of a high-strength, spun-bonded polypropylene fabric
  • Outer layers are thermally bonded to a highly vapor-permeable, watertight, polymeric middle layer
  • Adhesive is applied to the bottom layer of polypropylene
  • Dramatically exceeds the most stringent requirements of the Air Barrier Association of America (ABAA) based on the results of ASTM E2357 – 11 Standard Test Method for Determining Air Leakage of Air Barrier Assemblies
