Back-up for absorptive cladding
The Delta-Dry advanced ventilated rainscreen is designed for use behind absorptive cladding such as manufactured stone, stucco, and natural stone. The impermeable membrane is made from high-density polyethylene that provides dual-sided drainage, a complete capillary break, and drying capacity. Its double-sided dimple design ventilates the cavity and allows moisture to escape. Install between exterior sheathing and cladding to protect structures from water intrusion.

The Mortairvent two-ply mortar deflection and ventilation system is designed for use with manufactured stone, stucco, EIFS, and brick. A polymer core mesh creates air space between the weather-resistant barrier and exterior wall, while the filter fabric blocks mortar droppings from seeping into the wall cavity. Moisture can still pass through, ensuring a dry air space.

Ventilate brick walls
Combat the effects of mold, spalling, and efflorescence with the BrickVent moisture control system. It weeps out moisture and provides ventilation to quickly dry masonry walls. It is designed for easy installation by masons with any experience level. BrickVent does not require additional mortar blocking products.

Keep substrate dry
WaterWay Rainscreen Mats use a proprietary filter fabric that performs like an extra layer of housewrap. This material surpasses water hold-out requirements for weather resistive barriers and offers a perm rating of 247. WaterWay rainscreens create space for continuous ventilation and drain water faster than normal stone installations.

Allow water to drain
L+R Weep Screed (LR 3501) is designed to accommodate a rain screen drainage plane material and “weep.” This metal termination forms the bottom edge of the scratch coat and of the thin-set mortar. Large 1-in. slots along the bottom edge allow moisture to exit a thin veneer wall system m. Add the Weep Screed Deflector (WSD 1309) to direct moisture away from the he foundation.

Prevent moisture problems
Driwall Rainscreen's entangled net design eliminates incidental moisture problems in most exterior veneer applications, including stucco, manufactured stone, plank siding, and vinyl. The full wall product rolls over the weather-resistant barrier to separate it from the exterior veneer. This creates a space that increases airflow through the wall cavity, allowing the wall to breathe and stay dry and mold-free.
