DELTA®-VENT SA vapor permeable air- and water resistive barrier prevents moisture from getting into buildings. By also allowing moisture already in to escape, DELTA®-VENT SA eliminates the risk of mold and other problems caused by water pooling where it should not. Its vapor permeability and air tightness makes DELTA®-VENT SA ideal for building and maintaining healthy and comfortable interiors while letting moisture out and improving energy efficiency.
A critical component of any energy-efficient building enclosure. DELTA®-VENT SA improves the performance of the wall system by adhering to the substrate so fasteners are not required, eliminating leaks due to penetration. DELTA®-VENT SA is dimensionally stable and has the most tightly sealed and secure side laps in the industry.
