DELTA®-DRY & LATH is a 3-dimensional rainscreen membrane made out of a special high-density polyethylene. It provides two-sided drainage and ventilation through its unique dimple and groove design. DELTA®-DRY & LATH has a pre-installed glass lath which makes it ideal for absorptive claddings. The alkali-resistant (AR) glass lath replaces the wire lath for the application of the scratch coat.
