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-resisitant (AR) glass lath replaces the wire lath for the application of the scratch coat.
PROPERTIESThe structured membrane provides drainage and ventilation, as well as a complete capillary break behind the cladding. It protects the building enclosure from bulk water intrusion (i.e. wind-driven rain), and manages incidental water leakage through the cladding. As well, DELTA®-DRY & LATH captures and drains transient moisture migrating through the wall structure. DELTA®-DRY & LATH provides an air-gap on the interior and exterior side of the membrane for drainage and ventilation. It allows water vapor, driven from the interior to the exterior of the structure, to escape through the ventilated air space between the sheathing and the membrane. At the same time, DELTA®-DRY & LATH minimizes the potential for condensation that could cause damage within the building enclosure. The membrane provides drying potential through ventilation behind any approved exterior cladding. DELTA®- DRY & LATH impedes solar-driven moisture towards the interior of the structure as occurs with absorptive cladding materials like adhered manufactured stone veneer and conventional stucco. DELTA®-DRY & LATH reduces labor costs when used with claddings requiring a scrach coat. The 3-dimentional membrane and the glass lath are placed in a single installation procedure. The pre-installed AR glass lath is in compliance with ICC-ES AC 275.
APPLICATIONDELTA®-DRY & LATH is installed outboard of the water- resistive barrier over sheathing. The material cuts easily with a utility knife. Glass lath is overlapped at seams. Manufactured stone and conventional stucco are installed as per manufacturer’s instructions.
