DELTA®-VENT SA

Without reliable, long-term protection from air and moisture, your building’s performance will be significantly compromised. Dampness and mold can result in uncomfortable occupants and long-term water damage, and that can have an impact on your reputation. 

Sprays offer inconsistent, incomplete protection.

Sprays don’t provide enough protection – inconsistent application means inconsistent coverage. They don’t hold up when buildings shift, and they don’t provide a complete seal around fastener penetrations. In addition, they don’t provide the moisture permeability required to protect buildings from incidental moisture trapped inside the wall cavity. That’s why you need the reliability and long-term protection of DELTA®-VENT SA.  

DELTA®-VENT SA is the only self-adhering air- and water-resistive barrier with a self-adhesive edge lap. Its unique combination of industry-leading technology and complete application tools and support ensures your building stays air tight and water stays out of the wall system. 

A complete line of accessories for a continuous barrier.

The DELTA®-VENT SA system offers a complete line of accessories, ensuring that every corner, window, gap, and edge is 100% sealed. With a complete system, you don’t have to worry about any gaps or spaces being left during installation: buildings have a continuous barrier. It also features the industry’s highest permeability (50 perms) so your buildings stay drier and last longer.

BIM models and technical manuals make design and installation easier.

DELTA® is the only manufacturer who provides BIM models for an air- and water-resistive barrier, allowing you to draft architectural drawings and specify details quickly and with much less effort. We also offer the best technical manuals and installation videos in the industry, ensuring proper installation every time.


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
  • Self-adhesive edge lap
  • Dramatically exceeds the most stringent requirements of the Air Barrier Association of America (ABAA) and of the National Building Code of Canada (NBC 2010), 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
  • Vapor permeable – moisture within the building enclosure can escape through the membrane via diffusion
  • Fully adhered to the substrate, no fasteners required, eliminating leaks and improving the performance of the building enclosure making it ideal for energy-efficient construction
  • The full adhesion makes buildings are water tight, air tight and weather tight
  • 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 for 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 is available
