  • Typical thicknesses are 9.5mm and 12.5mm. Thicker sizes , eg 15mm or 18mm exist as well as thinner, eg 6mm.
  • Sheet sizes are commonly 2.4 x 1.2m (aka 8ft by 4ft, most usual size), and 1.8m x 0.9m (for easier handling, especially on ceilings).


  • Plain - paper both sides. Usually beige or grey in colour.
  • Vapour barrier or vapour check - usually with a metallised plastic film (which may degrade radio signals such as cordless telephones or Wifi).
  • Fire check - usually pink in colour
  • Moisture shield - for areas of high humidity, usually green.
  • Sound block or acoustic plasterboard - usually blue.
  • Various combinations of the above properties, dependant on manufacturer.

Edge finishes

  • Taper - for filling prior to painting direct.
  • Square edge - used when a skim coat of plaster is going to be applied.
