This section should be read in conjunction with the Products list.
- Framework Fixing: Ceiling sections fixed to primary framework using wafer head screws.
- Finishing Requirements: To achieve the specified performances, the system should be finished using Gyproc jointing products. See the product range guides on the British Gypsum website for more information.
- Loadbearing: No
- Maximum Ceiling Load (kg/m2): 30 kg/m²
- 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: Perimeter channel suitably fixed to background at 600mm centres.
- Screw: Fix ceiling boards securely to all supports at maximum 230mm centres (reduced to 150mm at board ends). Do not fix into ceiling perimeter framing. Fix working from the centre of each board. Position screws not less than 13mm from cut edges and 10mm from bound edges of boards. Set screw heads flush with plasterboard surface; do not break paper or gypsum core.
