Delta Vent S
The black, water and tear-resistant, vapor-permeable air barrier membrane of Delta Vent S resists water from wind-driven rain and snow. It allows moisture accumulation within the structure to escape via diffusion.
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
