DELTA®-VENT S

The Problem

To become more energy efficient, buildings are now being built with extreme airtightness. 

Building wraps are used, but are easily damaged during installation, and they can lead to unwanted, uncontrolled air movement – resulting in condensation.

The Solution

More and more structures are being built with higher-performance membranes to increase airtightness. The highest-performing barriers are fully adhered sheets that have a superior material as well as foolproof installation.

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.

Product Details
Product Benefits
  • 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
  • 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
