Description

A lightweight, non-loadbearing, steel 'I' stud, twin framed, acoustic separating wall that requires no bracing. As an approved Robust Detail construction (E-WS-2) it is primarily used in sound resisting walls for residential units, such as flats and apartments, to exceed the requirements of Building Regulations. The system can also be specified in commercial and industrial buildings where good acoustic performance is required.

The wall consists of two independent British Gypsum Metal Stud frames, with acoustic insulation suspended in the cavity and two or three layers of plasterboard screw fixed to each side.

Not suitable for use in areas subjected to continuous damp or humid conditions. Specify MR (moisture resistant) boards in intermittent wet areas.

Performance:

  • Strength and robustness: Satisfies BS 5234 requirements up to Severe Duty.
  • Fire resistance: Up to 120 minutes.
  • Approved Robust Detail (RD) construction: Can be used to meet Building Regulations, Approved Document E requirements without pre-completion testing.
