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.
Additional Information
Apply a water resistant barrier over sidewall sheeting. Check local building codes and specifications for more information.
Install Mortairvent® CW over installed rigid foam insulation board. Starting at the base of the wall unroll Mortairvent® CW from right to left between brick anchors with the three-dimensional (blue) polymer matrix side against the water resistant barrier and mortar deflection fabric facing exterior of building. Unroll the next course in the same manner as the first.
Be sure to always butt the blue polymer material together without overlapping.
Mortairvent® CW should be installed horizontally between brick ties as exterior brickwork is completed so as to maintain captivation within the brick anchoring system.
