Delta Vent S Air & Water Resistive Barrier

A black, water and tear-resistive, vapor permeable air barrier membrane.

Maximizes Air Tightness
  • High-performance water-resistive barrier
  • Two outer layers are made of a high-strength, spun-bonded polypropylene, thermally bonded to a highly vapor-permeable, watertight polymeric middle layer, on top of a protective fabric layer
  • High permeability
Benefits of Delta Vent S
  • Waterproof, resisting the passage of bulk water from wind-driven rain and snow
  • High permeability: moisture accumulation within the structure is able to escape via diffusion
  • Maximizes airtightness, making it ideal for energy-efficient construction
  • Fabric layer on the lower side protects the WRB against damage (e.g. roughly sawn sheathing)
  • Matte black; prevents blinding glare during installation
  • Lightweight, easily lined up and unrolled
  • Large roll size simplifies installation, while minimizing laps and maximizing productivity
