Details

This section should be read in conjunction with the Products list.

Core: Additional 0.7mm galvanised sheet can be located to one or both sides of core and fixed with wafer head jack-point screws at 150mm centres.
Deflection Allowance: Vertical deflection only. To be determined by a Structural Engineer.
Finishing Requirements: To achieve the specified performances, the system should be finished using either one of our Thistle or ThistlePro plasters, or Gyproc jointing products. See the product range guides on the British Gypsum website for more information.
Installation: Refer to British Gypsum for details of sitework instructions relating to individual installations
Loadbearing: No
Maximum Height: The maximum heights quoted are limited by the fire state field of application or by limiting deflection of L/240 at 200 Pa, whichever is the lower of the two.
Other Requirements: SpecSure^® system performance warranty confirms that British Gypsum proprietary systems will perform as specified for the lifetime of the building. The SpecSure^® warranty requires that all components are specified in full and constructed in accordance with British Gypsum’s installation guidance. For more details see the British Gypsum website. Always check with the design team before making any changes to the chosen specification, ensuring appropriate substantiation is sought to confirm that the solution still meets all required project performances.
Perimeter Framing: Fix perimeter framing using suitable M8 through bolt anchor type fixings at 300mm centres.
Screw: Board layer 1 (inner), fix securely at 300mm centres down vertical board edges and to each rib position along the horizontal board edges; Board layer 2 (outer), fixed at 300mm centres to vertical board edges and vertically within the field of the board (at each 'rib' position at approximately 200mm horizontal centres). All joints staggered between layers. Position screws not less than 13mm from edges of boards. Set screw heads flush with plasterboard surface; do not break gypsum core.
Sealant: Locate sealant at junctions with adjoining structure and other air paths. Apply as a continuous bead to clean, dry, dust-free surfaces, leaving no gaps. After application of sealant, bulk fill gaps between floor and underside of plasterboard using Gyproc joint compound.
Approx. Weight (kg/m2): 50 kg/m²
