DELTA®-Vent SA Vapor Permeable Barrier

Brand: Delta®

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.
