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 (USA, UK, Ireland, Australia), Gibraltar board or GIB wall and ceiling linings (in New Zealand, trademark of Winstone Wallboards), rock lath, 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.
