Spandrel Panels (Cold Roofs)

Spandrel panels used in cold roof voids to create separation between dwellings or to form the inner leaf of gable walls should be designed, manufactured and installed to provide satisfactory performance. Items to be taken into account include fire resistance, structural stability and acoustic transfer.

  • Blockwork at the party wall must be taken a minimum of 300mm above the ceiling line to comply with Robust Details.

  • Lateral restraint straps to masonry wall at 1200mm centres, on both sides of the wall.

  • Use 25mm x 100mm binder fixed to at least three trusses with 3.1mm x 65mm machine driven nails or 3.35mm x 65mm (10 gauge) ordinary nails.

  • Straps fixed to binder with eight 25mm x 4mm steel screw and fixed to the wall using screws and wall plugs.

  • Close off the cavity at the party wall and fire stop below the spandrel panel by using the ARC spandrel panel barrier.

  • Panel location straps at 1.2m centres face fixed into studs with a minimum of two 65mm screws and a minimum of three plug and screw fixings into at least two masonry blocks.
