A high-performance air barrier and moisture barrier resists air movement, and therefore moisture, by increased airtightness. Without the proper air barrier, and moisture barrier, your building could be at risk from moisture infiltration.
DELTA®-VENT SA - Highly Permeable Water-Resistive Barrier
The Problem
The Solution
DELTA®-VENT SA is a high-performance, 3-layer water-resistant barrier and air barrier. Highly permeable, watertight, and aggressively self-adhering, the product ensures protection from wind-driven rain.
Product Details
Product Benefits
- 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)
- Vapor permeable; moisture within the building enclosure can escape through the membrane via diffusion
- Fully adhered to the substrate, no fasteners are required, eliminating leaks and improving the performance of the building enclosure with increased airtightness, making it ideal for energy-efficient construction
- Lightweight and tear resistant, the membrane withstands the rigors of job sites, as well as tough wind and weather
- The only self-adhering WRB and air barrier with the security of a self-adhesive edge lap, allowing easy installation
- Installed outboard of the sheathing prior to the application of the final cladding system
- May be adhered to concrete, masonry, OSB, plywood, or exterior-grade drywall
- Where required, DELTA® Primer LVC or DELTA®-ADHESIVE is available.
