Delta Vent SA Air & Water Resistive Barrier

A gray, self-adhering, tear-resistive, vapor permeable air and moisture barrier membrane.

Air and Moisture Barrier Membrane
  • 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
  • Exceeds the requirements of a 60-minute Grade D building paper
  • Passes ASTM D1970 Nail Sealability test for sealing around fasteners
  • Class A fire rated
  • Sizes offered: 4’ 11” x 115’ (1.5 m x 35 m), 9.75 ” x 115′ (0.25 m x 35 m), 19.5″ x 115′ (0.5 m x 35 m)
Benefits of Delta Vent SA
  • 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
  • The only self-adhering WRB and air barrier with the security of a self-adhesive edge lap, allowing easy installation
  • Installed outboard of the sheathing prior to the application of the final cladding system
  • May be adhered to concrete, masonry, OSB, plywood, or exterior-grade drywall
  • Where required, DELTA® Primer LVC or DELTA®-ADHESIVE is available.
