Can I get a pass with a single leaf timber stud wall?

It is possible to achieve a DnTw+Ctr of 45 with a single leaf timber stud construction. The following example shows a plasterboard partition wall with timber studs that passes this criterion:

ST20

  • air gap: 150mm
  • panel thickness: 12.5mm/layer
  • insulation: fiberglass (22kg/m3)
  • insulation thickness: 50mm
