5 T F E bgtechnical.enquiries@bpb.com Installation overview Gypframe Floor & Ceiling Channel is fixed at the head and base. Gypframe studs are fitted vertically to a friction-fit within the channel sections, and to abutments, to form the framework. This allows for adjustment during boarding. Studs are fitted so as to all face the same way. Additional framing is installed as required to support heavy fixtures. Boards are screw-fixed to framing members to form the lining. Horizontal board-end joints of face lining boards should be backed with Gypframe GFS Fixing Strap (double layer) or Gypframe GFT Fixing T (single layer). Openings Details for openings differ according to Duty requirements. See Design - Openings for further details. Services Electrical and other services are normally installed after one side is boarded. Horizontal runs are routed through cut-outs in the studs. Gypframe 99 FC 0 Fixing Channel can be installed between studs to support recessed switch boxes / socket outlets, or a high performance socket box detail used where higher acoustic performance is required.

20 Design Planning - key factors The position of services and heavy fixtures should be pre-determined and their installation planned into the frame erection stage. Wind loading GypWall partitions are non-loadbearing but can accept a degree of wind loading, for example when used in buildings with large or multiple external doors. Refer to. Robustness. Cavity fire barriers Minimum.mm Gyproc plasterboard, screw-fixed into the web of perimeter channels or vertical studs, will provide a satisfactory closure to flame or smoke. Refer to Cavity fire barriers. Services Penetrations Penetrations of fire-resistant or sound-insulating constructions for services need careful consideration to ensure that the performance of the element is not downgraded and also that the services themselves do not act as the mechanism of fire spread or sound transmission. Refer to. Service installations. Independent support When designing for the installation of services such as fire dampers and associated ductwork through a GypWall partition, consideration should be given to the size and weight of the damper - this will determine whether it can be supported directly from the partition or needs to be independently supported from the structure. Refer to. Service installations. Electrical The installation of electrical services should be carried out in accordance with the recommendations of the Institution of Electrical Engineers. The cut-outs in the studs can be used for routing electrical and other small services (see Construction details - ). Switch boxes and socket outlets can be supported from Gypframe 99 FC 0 Fixing Channel fixed horizontally between studs, or a high performance socket box detail used where higher acoustic performance is required. Where Gypframe AcouStuds are used, services are routed through 0mm x 8mm H shaped push-outs, at the same centres as shown in Construction details - for conventional cut-outs. Cables should be protected by conduit, or other suitable precautions taken to prevent abrasion when they pass through the metal frame. Fixing floor and ceiling channels Floor channels must be securely fixed with a row of fixings at 600mm maximum centres. With 9mm and 8mm channels, two rows of staggered fixings are required, each row at 600mm centres and each fixing mm in from the flange. If the floor is uneven, a 8mm thick timber sole plate equal to the width of the channel should be used. If the concrete or screeded floor is new, consideration should be given to the installation of a damp proof membrane between the floor surface and the channel or sole plate. Ceiling channels must be securely fixed at 600mm maximum centres. With 9mm and 8mm channels, two rows of staggered fixings are required, each row at 600mm centres and each fixing mm in from the flange. Extra support may be necessary to provide positive fixing points with some constructions. Door openings The designer should consider thickness tolerances of the partition types in relation to the proposed door frame detail. Standard door frame detailing to suit BS ight and Medium Duty applications is shown in Construction details -. Detailing to satisfy BS : 99 requirements for Heavy and Severe Duty is shown in Construction details -. Where additional provision is required to support heavy doorsets contact the British Gypsum Drywall Academy Technical Advice Centre for guidance. The door manufacturer should also be consulted in relation to door details. Framing surround for openings Where services such as horizontal ducts, fire dampers and access panels are required to penetrate the wall, their position should be predetermined in order that a framed opening can be provided. The openings should be constructed using established metal stud procedures. See Construction details - -. Control joints Control joints may be required in the partition to relieve stresses induced by expansion and contraction of the structure (see Construction details - ). They should coincide with movement joints within the surrounding structure. Deflection heads Partition head deflection designs may be necessary to accommodate deflections in the supporting floor. Deflection heads may also be required to the underside of roof structures subjected to positive and negative pressures. Refer to Construction details For special detailing which minimises the loss of acoustic performance: Refer to Basic principles of system design. Access for maintenance Where access is required within the partition, to maintain services for example, Gyproc Profilex Access Panels should be used. Fixtures ightweight fixtures can be made directly to the partition linings. Medium weight fixtures can be made to Gypframe 99 FC 0 Fixing Channel. Heavy fixtures should be made to the metal studs or independent framing installed before boarding. Refer to.. Robustness, Fixings into drywall systems. Board finishing Refer to 0 Finishing systems and decorative effects. Please refer to - Basic principles of system design for general guidance. 8
