Cementitious Wood-Fiber Deck Panels

Cementitious wood-fiber roof deck panels are composed of treated wood fibers, which are bonded together with cement and/or other binders, compressed and molded into panels. Structural cementitious wood-fiber panels provide structural support, as well as acoustical and thermal insulation. The panels are available with tongue and groove joints for application directly over joists and with rabbeted joints for use over subpurlins or bulb trees.
