CCW-705 RS is a robust, UV-resistant engineered fabric designed for use as a blackout membrane behind open-joint rain screen claddings. When installed over exterior wall insulation, 705 RS also protects the insulation from rain water and wind washing. 705 RS is mechanically attached and neighboring pieces are shingle-lapped. The black 705 RS fabric bears a black imprint of the brand name and lap lines, facilitating product identification and installation. The imprint on the 705 RS fabric is not apparent once the rain screen cladding is installed.
