Details
This section should be read in conjunction with the Products list.
- Abutment Fixing: Gypframe 'C' stud suitably fixed to structure at 600mm centres in two lines staggered by 300mm.
- Background: Suitable structural background.
- Base Channel Fixing: Gypframe channel suitably fixed to floor at 600mm centres in two lines staggered by 300mm.
- Deflection Allowance: Vertical deflection only. To be determined by a Structural Engineer.
- 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.
- Fixing Strap: Used to support horizontal board joints and enable board screw fixing at 300mm centres.
- Fixing T: Used to support horizontal board joints and enable board screw fixing at 300mm centres.
- Loadbearing: No
- Maximum Height: The maximum heights quoted are based upon a limiting deflection of L/240 at 200 Pa.
- Screw: Board layer 1, fix securely to Gypframe metal supports around the perimeter of the board and intermediate stud positions at maximum 300mm centres. External corners reduce fixings to 200mm. Drywall screws can be used for fixing boards to metal profiles with a thickness of 0.8mm or less (excluding 'I' studs). 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. After application of sealant, bulk fill gaps between floor and underside of plasterboard using Gyproc jointing compound.
- Stud Centres (mm): 600 mm
- Approx. Weight (kg/m2): 14 kg/m²
- Head Channel Fixing: Gypframe channel suitably fixed to soffit at 600mm centres in two lines staggered by 300mm.
- Minimum Cavity / Offset (mm): 30 mm
- Framework / Lining: One Side
