Description

A high performance, non-loadbearing, twin-frame wall system that provides exceptional levels of sound insulation. It is used to separate multiple use facilities, such as lecture theatres, music rooms, multi-screen cinemas, exhibition and conference centres, and leisure centres.

The wall is constructed from two independent Gypframe studs and channels, spaced to give an overall partition width of 300–800 mm. The frames are braced using Gypframe Acoustic Braces or solid braces formed from Gypframe 99 FC 50 Fixing Channel. Layers of insulation are suspended in the cavity, and two or three layers of plasterboard are screw fixed to form the linings.

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.
  • Sound insulation, Rw: Up to 80 dB.
