Gypsum board is the name for a family of panel products consisting of a noncombustible core, primarily of gypsum, with a paper surfacing on the face, back and long edges.
The popularity of gypsum wallboard results from a number of factors. First, it takes virtually any decoration-from paint or textures to vinyl and paper laminates. It also lends itself to creative shaping of interior surfaces, allowing the maximum in design flexibility. Gypsum wallboard is an economical alternative to other products. Because it is lightweight, it is easy to handle for speedy installation. With its natural properties, it is durable yet easy to repair. In addition, gypsum wallboard's fire resistance and sound control capabilities further demonstrate its desirability in building systems.
Gypsum wallboard is available with a variety of edge configurations. For easy joint finishing, the tapered edge is preferred to provide a monolithic surface. Where joints will be exposed, square or beveled edges should be considered.
