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
