6.3.12 Plasterboard

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

Dry lining should comply with BS 8000-8. Plasterboard should be to BS EN 520, or BS EN 15283 and be:

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

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

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

For guidance on the use of plasterboard in wet areas ie, bath and shower areas, please refer to Chapter 9.2 ‘Wall and ceiling finishes'.
