This section should be read in conjunction with the Products list.
- Abutment Fixing: SFS stud (70mm x 50mm x 1.2mm) suitably fixed to structure at 600mm centres.
- Base Channel Fixing: SFS channel (75mm x 38mm x 1.2mm) suitably fixed to floor at 600mm centres. All SFS components are supplied direct from Hadley Group.
- Clips: Fix the slip klip component to the head channel with four British Gypsum Wafer Head Jack-Point Screws 13mm.
- Deflection Allowance: For vertical movement up to 20mm. To be determined by a Structural Engineer.
- Dropped Soffit: For principles of deflection head construction refer to detail ST‐225-ZZL3-01
- 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 to the internal face. 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.
- Fixing Strap: Used to support horizontal board joints to internal side and enable board screw fixing at 300mm centres.
- Loadbearing: No
- Maximum Height: The maximum heights quoted are limited by the fire state field of application or by limiting deflection of L/240 at 200 Pa, whichever is the lower of the two.
- 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: Board side 1, Layer 1 (inner) and Layer 2 (middle), fix securely to SFS supports around the perimeter of the board at maximum 300mm centres except the head channel; Board side 1, Layer 3 (outer), fix securely to all SFS supports around the perimeter of the board and intermediate stud positions at maximum 300mm centres except the head channel. The uppermost board fixings are positioned 130mm below the structural soffit through board in to fixing strap. Board side 2, Layer 1, fix securely to all SFS supports around the perimeter of the board and intermediate stud positions at maximum 300mm centres except the head channel. The uppermost board fixings are positioned 130mm below the structural soffit. External corners reduce fixings to 200mm. All joints staggered between layers. First fixing of the external board into the stud should be 100mm above the floor channel leg and then fixed working up the stud (board side 2). Fix working from the centre of each board on the internal side (board side 1). 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 gypsum core.
- Sealant: On the internal side, 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. After application of sealant, bulk fill gaps between floor and underside of plasterboard using Gyproc joint compound.
- Stud Centres (mm): 600 mm
- Approx. Weight (kg/m2): 50 kg/m²
- Head Channel Fixing: SFS channel (75mm x 70mm x 2.0mm) suitably fixed to soffit at 600mm centres.
- External board joints: Apply a continuous 6mm bead of Glasroc X Sealant along vertical and horizontal edges of board where boards will abut each other. Push the sheathing board up to the previous board ensuring the sealant 'mushroomed' out fully sealing the joint.
- Stud Fixing: SFS studs (70mm x 50mm x 1.2mm) should be cut 25mm short and engaged into a slip klip.
