A brief history…

stack of Drywall sheets Plasterboard was created in 1916 by the Gypsum company and was derived from Sackett board invented in the late 1800s. Created as a cheaper and quicker form of plaster, it was not used by mainstream builders until the 1940s, when World War Two called for cheaper housing.

Previously, plasterboard was seen as a quick fix to house building. However, by the 1950s builders had seen its benefits and were using it for the majority of house building.

What is plasterboard?

labelled parts of drywall; gypsum core and front paper A sheet of plasterboard consists of a hardened gypsum core between two layers of paper.

The face side front paper is a strong, smooth finished paper impregnated with gypsum crystals to aid bonding of the plaster coat (or skim), while the reverse is covered in a rougher ‘natural’ paper.

  Plasterboard sheets are available in lengths of up to 4.8m (16ft) with 1220mm (48″) and 1370mm (54″) widths.

The most common size for domestic building work tends to be 2440mm x 1220mm and is based on the old imperial 8 ft x 4 ft boards to cover the common ceiling heights of a little over 2440mm (8ft).
