Premium self-adhesive water-resistive and air barrier. Highly vapor permeable, water-tight, and aggresively self-adhering. The only self-adhering WRB and air barrier with the security of a self-adhesive edge lap.
DELTA®-VENT SA eliminates leaks at fasteners and helps improve the performance of the building enclosure with increased air-tightness.
DELTA®-VENT SA not only passes, but also 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.
DELTA®-VENT SA is the only self-adhering vapor permeable air and water resistive barrier evaluated and approved by ABAA.
DELTA®-VENT SA is a vapor permeable WRB, allowing moisture within the building enclosure to escape through the membrane via diffusion. Its permeability and air-tightness make it an ideal air and water-resistive barrier membrane for energy-efficient construction. Full adhesion maximizes air tightness and minimizes fastener penetrations. The product is watertight and protects the building enclosure from wind-driven rain. DELTA®-VENT SA is very light-weight and tear-resistant. This membrane withstands the rigors of jobsites, as well as tough wind and weather. DELTA®-VENT SA is equivalant to a 60 minute Grade D building paper.
DELTA®-VENT SA has a glue strip with a release liner on the front side of the top edge. This makes a locked tight glue-to-glue sealed lap, eliminating the possibility of peeling at material laps.
DELTA®-VENT SA is Class A fire-rated. Its vapor permeable, air barrier,self-adhesive, and watertight qualities are unaffected by surfactants.
Because DELTA®-VENT SA is fully adhered to the substrate, no fasteners are required and lateral movement of air and water is eliminated.
Energy efficiency is very important to owners, architects and building occupants. Air tightness and continuity of the air barrier are critical criteria when designing the building enclosure. DELTA®-VENT SA adheres fully to common substrates. DELTA®-VENT SA allows the insulation and other building components to function to their full potential by blocking wind and water from the wall.
Full adhesion means full air tightness, because many potential leak points are eliminated. No longer is the air barrier penetrated by hundreds of fasteners just to install the membrane itself. Every eliminated fastener is a potential leak point eliminated.
DELTA®-VENT SA also has the exclusive locked tight seam. An additional strip of adhesive on the front side of the membrane where overlaps will occur ensures the seam gets a permanent glue-to-glue seal. No worries about peeling or lifting during either the construction phase or the service life of the building.
Full adhesion prevents the potential of lateral movement of air convections and water bewteen the membrane and the substrate.
DELTA®-VENT SA is light yet strong enough to stand up to the rigors of the jobsite.
DELTA®-VENT SA comes with a convenient split-release liner that makes installation quick and easy.
Details as very similar to a standard air barrier application, but without all the fasteners.
