This section should be read in conjunction with the Products list.
- Framework Fixing: For corners and alcoves the perimeter framing is arranged back to back and fixed together using wafer head screws at 300mm centres. The ends of the perimeter framing are secured using a soffit cleat connection, fixed using wafer head screws and suitably fixed to structure.
- Loadbearing: No
- 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 framing can be suitably fixed to the structure or timber batten at 300mm centres.
- Structural Background: Concrete
- Maximum Cavity / Plenum (mm): 2010 mm
- Minimum Cavity / Plenum (mm): 200 mm
- Primary Framework Centres (mm): 300 mm
- Suspension Type: Suspend ceiling at corners and alcoves using grid hangers with an appropriate size for the required plenum, secured to soffit cleat via hook. Alternatively, suspension wire (min. 14 swg by others) secured to soffit using fixings recommended by suspended ceiling contractor. Suspension should be a maximum of 300mm from a perimeter.
- Suspension Type Centres (mm): 600 mm
