A system and method for making wallboard or backerboard sheets may include mixing materials for making aerated concrete with a mixer, supplying at leas t one face layer from a supply, and forming, downstream from the mixer, core material having opposing first and second major surfaces and including aerat ed concrete. At least one face layer from the at least one face layer supply is secured onto at least one of the first and second major surfaces of the core material. A cutter, downstream from the former, cuts the core material and a t least one face layer secured thereto into a plurality of wallboard or backerboard sheets. The provision of aerated concrete for the core provides many key advantages over conventional gypsum wallboard sheets, and/or conventional backerboard sheets, such as gypsum greenboard or cementitious backerboard, for example. In one class of embodiments, the former may furthe r include an autoclave for curing the core material prior to securing the at least one face layer thereto. In another class, the former may further inclu de an autoclave for curing the core material after securing the at least one fa ce layer thereto. |
