Backerboard sheet including aerated concrete core

Abstract

A backerboard sheet is for moist areas and includes a core having opposing first and second major surfaces, at least one moisture-resistant face layer on at least one of the first and second major surfaces of the core; and wherein the core includes aerated concrete. The provision of aerated concrete for the core provides many key advantages over conventional backerboard sheets, such as gypsum greenboard or cementitious backerboard, for example. The at least one moisture-resistant face layer may include fibers, such as arranged in a woven mesh. The fibers may include at least one of glass, plastic, and metal. In addition, the at least one moisture-resistant face layer may further include a moisture-resistant material incorporating the fibers, such as a suitable resin, for example.
