6.3.10Plasterboard

Plasterboard shall be of a suitable thickness for its intended use.

Dry lining should comply with BS 8212. Plasterboard should be to BS 1230, and be:

  • 9.5mm for stud spacing up to 450mm
  • 12.5mm for stud spacing up to 600mm.

For sound-resisting walls (e.g. separating walls and walls to WCs), the correct thickness, number of layers and sealing should be specified in the design information.

Tapered edge boards should be used where the plasterboard is to be jointed before decoration.
