Tests for fire resistance and sound transmission, performed by independent laboratories, have resulted in specific ratings for walls/partitions floor/ceiling assemblies shaftwalls, stairwells and area separation walls and columns. Where joints will be exposed, square or beveled edges should be considered.įire and sound ratings for building systems utilizing gypsum wallboard are dependent on the core type and thickness of the wallboard, its application in conjunction with the component parts, and the manner in which it is applied.

For easy joint finishing, the tapered edge is preferred to provide a monolithic surface. Gypsum wallboard is available with a variety of edge configurations. In addition, gypsum wallboard’s fire resistance and sound control capabilities further demonstrate its desirability in building systems. With its natural properties, it is durable yet easy to repair. Because it is lightweight, it is easy to handle for speedy installation. Gypsum wallboard is an economical alternative to other products. It also lends itself to creative shaping of interior surfaces, allowing the maximum in design flexibility. First, it takes virtually any decoration-from paint or textures to vinyl and paper laminates.
