ABSTRACT:
A lightweight cementitious panel/tile is provided with increased bending stiffness and less weight than conventional construction panels. The cementitious panel is constructed of a cementitious surface (which may be reinforced with wood fiber or other materials) supported by an integrated stiffener grid on the underside to absorb stresses and loads.
