Details
This section should be read in conjunction with the Products list.
- Abutment Fixing: Channels suitably fixed to abutment at 300mm centres.
- Framework Fixing: Gypframe 'I' studs fixed in to Gypframe channel through bottom flange with two 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. For further guidance on skimming moisture resistant grade boards see the White Book - Finishes section.
- Horizontal Joint: Horizontal board joints in core layer closed off by inserting steel angle between board joints and 122mm strip of core board fire stop with beads of sealant along both longer edges fixed to angle using three drywall screws.
- Loadbearing: No
- Maximum Span (mm): 2800 mm
- 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 positioned tight up to abutment channels and suitably fixed to background at 600mm centres.
- Retaining Channel: Retaining channels inserted between the face of the coreboard and the lower flange of the stud / starter channel.
- Screw: Fix all ceiling boards securely to all supports at 230mm maximum centres in the field of the board and at 150mm maximum centres along the short 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. For pressurised airshafts and service ducts apply a continuous bead of sealant leaving no gaps to all framing members at perimeter junctions with walls, air gaps around openings, and other potential air leakage points. To frame members prior to fitting core boards and around fire stops cloaking horizontal core board joints. To all metal framing around board perimeters of first layer boarding and board perimeters when fixing outer layer board.
- Approx. Weight (kg/m2): 39 kg/m²
- Primary Framework Centres (mm): 600 mm
- Secondary Framework Centres (mm): 450 mm
- Secondary Framework: Secondary framework fixed to primary framework using two wafer head screws per connection.
