Details
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 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.
- Fixing Strap: Used to support the outer layer longitudinal board joint and enable screw fixing at 200mm centres using British Gypsum Drywall Screws 25mm.
- Loadbearing: No
- Maximum Ceiling Load (kg/m2): 60 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: Ceiling board, Layers 1, 2 and 3, fix securely to all supports at maximum 230mm centres (reduced to 150mm at board ends and at ceiling perimeters). Ceiling board, Layer 4, fix securely to all supports at maximum 230mm centres within the field of the board, at 400mm centres along the longitudinal board joints in to each Gypframe MF5 Ceiling Support (reduced to 150mm at board ends and at ceiling perimeters). In addition the longitudinal board joints are fixed to the fixing strap at 200mm centres. All joints staggered between layers. 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.
- 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.
- Structural Background: Floor or Roof Cavity
- Approx. Weight (kg/m2): 52 kg/m²
- Maximum Cavity / Plenum (mm): 5600 mm
- Minimum Cavity / Plenum (mm): 175 mm
- Primary Framework Centres (mm): 600 mm
- Secondary Framework Centres (mm): 400 mm
- Suspension Type: Strap hanger should be used for suspension up to 1000mm. Steel angle section can be used up to 5600mm.
- Suspension Type Centres (mm): 1200 mm
