Details
This section should be read in conjunction with the Products list.
- Framework Fixing: Ceiling sections fixed to primary framework using wafer head screws or clips.
- Finishing Requirements: Finishing is not required to achieve the specified performance, but the system can 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.
- Loadbearing: No
- Maximum Ceiling Load (kg/m2): 30 kg/m²
- 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 and at ceiling perimeters). 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: Suitable structural background.
- Approx. Weight (kg/m2): 23 kg/m²
- Maximum Cavity / Plenum (mm): 5600 mm
- Minimum Cavity / Plenum (mm): 150 mm
- Primary Framework Centres (mm): 1200 mm
- Secondary Framework Centres (mm): 450 mm
- Suspension Type: Strap hanger should be used for suspension up to 1000mm. Steel angle section can be used up to 5600mm.
