Driwall™ Rain Screen by Keene Building Products is an exterior wall drain product for use behind traditional stucco, EIFS, manufactured stone, fiber cement, metal panels, and continuous insulation applications. Drainage channels provide a drain path and ventilation cavity for incidental moisture between exterior wall finish materials and weather barrier sheathing. This product design combines the benefit of compressive strength per traditional testing measurements with a spring-like structure. This product is designed for commercial or residential applications.
Highly resistant to compression even after attachment, Driwall™ Rain Screen replaces the second layer of WRB and maintains the integrity of the drainage cavity by ensuring gravity-induced moisture can flow to the bottom of the wall and water vapor can escape the top of the wall. Tested and CFD modeled to drain in excess of 150 gallons per hour when combined with the HYDRODRY® system.
Driwall™ Rain Screen creates a drainage and ventilation cavity that allows the interior of the wall to drain, vent and dry.
