WHAT IS PLASTERBOARD?

Plasterboard is a type of sheet material made from gypsum (calcium sulphate dihydrate) that is pressed between a backer and a facer layer. It is great for use in areas that experience high levels of humidity.  It is often used for interior walls, ceilings, and partitions.  Plasterboard is also known as drywall, gypsum board, wallboard, and other variants of these names.
