Delta Vent SA
The gray, self-adhering, tear-resistant, vapor-permeable air and moisture barrier membrane of Delta Vent SA adheres to the substrate without fasteners. It eliminates leaks and improves the performance of the building enclosure by increasing airtightness which enables an energy-efficient building.
Air and Moisture Barrier Membrane
- Two outer layers are made of a high-strength, spun-bonded polypropylene fabric
- Outer layers are thermally bonded to a highly vapor-permeable, watertight, polymeric middle layer
- Adhesive is applied to the bottom layer of polypropylene
- Dramatically exceeds the most stringent requirements of the Air Barrier Association of America (ABAA) based on the results of ASTM E2357 – 11 Standard Test Method for Determining Air Leakage of Air Barrier Assemblies
- Exceeds the requirements of a 60-minute Grade D building paper
- Passes ASTM D1970 Nail Sealability test for sealing around fasteners
- Class A fire rated
- Sizes offered: 4’ 11” x 115’ (1.5 m x 35 m), 9.75 ” x 115′ (0.25 m x 35 m), 19.5″ x 115′ (0.5 m x 35 m)
