Mortairvent Rainscreen, perfect for all exterior siding applications. Our innovative RAINSCREEN technology equalizes the air pressure within the wall system by creating a drainage and ventilation cavity between the weather resistant barrier (WRB) and the exterior wall. This design allows excess moisture to drain from the wall system and allows ventilated air to circulate and dry the interior wall components.

The Mortairvent® CW Mortar Deflection and Ventilation System is a full cavity wall product that combines the benefits of RAINSCREEN technology through the use of integrated mortar deflection, drainage and ventilation design. The result is an easy to install system that improves the overall performance of the interior wythe while also providing drainage and ventilation for the entire cavity wall.
