Delta Vent S Weather Barrier

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.

Benefits

• Waterproof to resist rain and snow
• High permeability; moisture escapes via diffusion
• Maximizes airtightness for energy-efficient construction
• Fabric layer on the lower side to protect the WRD against damage
• Matte black; prevents blinding during installation
• Lightweight; easily lined up and unrolled
• Large roll size to simplify installation and maximize productivity
