DELTA®-VENT S is a heavy duty, highly permeable water-resistive barrier and air barrier. The 3-layer, spun-bonded polypropylene is suitable for all wall applications.

Features

• 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 air tightness, 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
