摘要: A gypsum wallboard may have a paper-covered first face with shaped regions formed along side portions near the wallboard edges, and a fibrous mat-covered second face. The fibrous mat material covering the second face extends around the wallboard edges and is overlapped by portions of the paper on the first face. The wallboard can be manufactured by depositing a gypsum slurry onto a moving web of the fibrous mat material, applying a web of the paper to the deposited gypsum slurry, and forming shaped regions in the side portions of the top surface.
