        Drywall

        Date:Jul 17,2011

          Drywall, Plasterboard or also called gypsum board are panels made of gypsum plaster pressed between two thick sheets of paper, the panels are used to make interior walls and ceilings.   Plasterboard panels are also known as wallboard[citation needed] (USA, UK, Ireland, Australia), Gibraltar board or GIB wall and ceiling linings (in New Zealand, trademark of Winstone Wallboards[1]), rock lath,[2] Sheetrock (a trademark of USG Corporation), Gyproc (a trademark of Compagnie de Saint-Gobain).   The sheets of the drywall can be made from fiberglass instead of paper to prevent mold growth. Mold growth is common when using paper based plasterboard that has been exposed to water due to plumbing leaks or floods.   Drywall construction became prevalent as a speedier alternative to using plaster based interior finish techniques, which involved forcefully spreading a substrate of coarse plaster, known as the base (made up of the scratch coat and (optional) brown coat), onto the wall's lath-work before finally applying the smoother finish coat, each layer added in succession and all by hand (see lath and plaster).[3] Drywall, by contrast to plaster, requires hand finishing only at the fasteners and joints. The drywall process requires less labor and drying time, lending its name to the panels used in the assembly.[citation needed]
