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.
