Definition:
Gypsum Wallboard, also known as Drywall, is a panel used typically in interior construction to form a wall or ceiling. The panel has a gypsum core and is faced with heavy paper on both sides, one side specially treated for finishing. Also known as Gyp Board or Drywall, these versatile panels are usually used in 1/2" and 5/8" thickness in home repair projects. Gypsum Wallboard may also have a special treatment of adding noncombustible fibers to the gypsum for fire improved rating "Type X."
