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. Now stronger and more durable than ever before! It may be exposed during the construction period up to 1 year, depending on the climate zone of the site.
DELTA®-VENT SA - Highly Permeable Water-Resistive Barrier
The Problems
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.

• Long allowable UV exposure time allows for maximum schedule flexibility
• 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.
