Wallboard
Description
Any rigid sheet of material used for covering interior walls and ceilings. Wallboards are used as a substitute for Plaster, as decoration and as quick or temporary support surfaces. Wallboard has been made from a variety of materials over the years. In 1772, Henry Clay received a patent in England for esll panels produced with paper layers. Originally, wallboards were a laminated Pasteboard made from wood pulp, waste paper, Bagasse, or rags. The paper panels were soaked in linseed oil, dried, then painted or lacquered. In 1926, the Masonite® process for producing a thin, dense Fiberboard, or Hardboard, was developed. A third type of wallboard made from Gypsum is called drywall or plasterboard. It is composed of a gypsum core sandwiched between two layers of paper. Gypsum board is fire resistance, dimensionally stable, and inexpensive. Examples of some types of wallboard are: Beaverboard; Upson board, Masonite®; Iso-board; Medex, Particle board, Duron®, Waferboard, Drywall, and Sheetrock®.
