Delta Dry Rainscreen

The structured membrane provides drainage and ventilation, as well as a complete capillary break behind the cladding. It protects the building envelope from bulk water intrusion (i.e. wind driven rain), and manages water leakage through the cladding. As well, DELTA®-DRY captures and drains transient moisture migrating through the wall structure. DELTA®-DRY provides an air-gap on the interior and exterior side of the membrane for drainage and ventilation. 11mm
DELTA®-DRY is installed outboard of the Water Resistive Barrier over sheathing board. It also provides excellent performance if installed in lieu of a conventional WRB, where building authorities allow this type of application. The material cuts easily with a utility knife. Seams are overlapped about 3 inches. Exterior cladding material can be installed as usual right on top of DELTA®-DRY. For further details please check the installation instructions.
DELTA®-DRY allows water vapor, driven from the interior to the exterior of the structure, to escape through the ventilated air space between the sheathing board and the membrane, while minimizing the potential for condensation that could cause damage within the building enclosure.
The membrane provides excellent drying potential through ventilation behind any approved exterior cladding. At the same time, it impedes solar-driven moisture towards the interior of the structure, such as occurs with absorptive cladding materials like adhered manufactured stone veneer, stucco, cement board siding, brick veneer, etc.

GREAT service
Bought this to install on the interior of stucco-covered plank walls before I hung batts, to provide air flow but block water absorption. Easy to cut and hang - and the shipping turnaround time with Spycor was fabulous! Happily bought a second roll, equally great service.
