The Corium Cladding System is comprised of genuine brick tiles with a patented profile that mechanically fixes to an HPS200 coated and galvanized receiver tray. Each tray interlocks to form a drainage plane, which is mounted to the framing system. The engineered rainscreen assembly has rear ventilation, which provides an open cavity, an uninterrupted air/moisture barrier, and continuous insulation capability for maximum thermal and moisture performance.
