Details
This section should be read in conjunction with the Products list.
- Background: Steel column or beam
- 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.
- Installation: Fix continuous lengths of steel angle onto face of innermost steel flanges or background using suitable fire resistant fixings at 600mm centres (3-sided encasement only). Friction fit framing clips to steel flanges at 800mm maximum centres and 100mm from each end of encasement; ensure that clips are fully engaged and aligned. Lining channels are clipped over steel framing clips and can be extended by using channel connectors. For single layer encasements joints, install Gypframe GFT1 Fixing 'T' or short sections of lining channel with ends tabbed and fixed to framing using wafer head screws. For multiple layer encasements, Install fixing strap between layers to support outer layer board joints. Stagger joints between adjacent faces and between layers by a minimum 600mm centres. If the steel section web or flange dimension exceeds 600mm, a nogging should be formed from lining channels with ends tabbed, installed at 600mm maximum centres, fixed to framing using wafer head screws. Fix noggings to coincide with a board end joints.
- 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.
- Screw: Boards are fixed securely to Gypframe metal supports at maximum 300mm centres. Fix working from the centre of each board and position screws not less than 13mm from cut edges; 10mm from bound edges of boards. Set screw heads flush with plasterboard surface; do not break paper or gypsum core.
- Encasement: The maximum permitted steel size which can be encased is 600mm.
