Delta Vent SA 4'11" x 115' - 565.1 Sq Ft/Roll

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. 

• 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
• 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 air tightness, 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
• 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
