4 T F E bgtechnical.enquiries@bpb.com Installation overview Fixing to a concrete soffit Gypframe GL8 Track is fixed at the perimeter with the longer leg at the bottom. Gypframe GL or GL9 Brackets are fixed at the required centres. Gypframe GL Lining Channel is located into the perimeter track and each leg of the GL or GL9 Bracket is screwfixed to the Gypframe GL Lining Channel. The protruding legs of each bracket are bent to sit back from the channel face. Gypframe GL Lining Channel sections are joined using Gypframe GL3 Channel Connectors. Additional channel or supplementary framing is installed if required to support fixtures. Boards are fixed to the Gypframe GL Lining Channels to form one or two layer linings as specified. Additional channel or supplementary framing is installed if required to support fixtures. Boards are fixed to the Gypframe GL Lining Channels to form one or two layer linings as specified. If the existing ceiling is to be retained, Gypframe GL6 Timber Connectors can be bent to form a right-angle and fixed to joists through the retained ceiling with suitable fixings. Each connector is bent at a position between the third and fourth holes along to give a 30mm horizontal leg. Gypframe GL Lining Channels are located and boards fixed through to form the new ceiling. Fixing to timber joists Gypframe GL or GL6 Timber Connectors are fixed to the side of joists using Gyproc Drywall Screws. The connectors must be aligned accurately since they can not be adjusted once Gypframe GL Lining Channel is engaged into a row of timber connectors and twisted into position. The channels are located into Gypframe GL8 Track at the perimeter. Gypframe GL Lining Channel sections are joined using Gypframe GL3 Channel Connectors.

9 Design Planning - key factors The depth of the ceiling cavity is determined by the positioning of the fixing brackets. For concrete soffits the fixing brackets allow sufficient adjustment for levelling the ceiling. Allow for a stand-off of mm 7mm plus the lining thickness when using Gypframe GL Brackets, or mm mm plus lining thickness when using Gypframe GL9 Brackets. When fixing to timber joists using Gypframe GL or GL6 Timber Connectors, allow for a maximum cavity depth of 3mm and 0mm respectively measured from the bottom of the joists to the underside of the lining. Cavity barriers Where cavity barriers are required these can be formed using Gyproc FireLine or Glasroc MultiBoard screw-fixed to a simple metal frame. The framing should be fixed to the structure to avoid undue loading of the ceiling suspension system. Refer to 7 Cavity fire barriers. Fixing to the structure When lining concrete soffits, fixing brackets should be positioned equidistant at up to 00mm maximum centres. Gypframe GL GypLyner Anchors are suitable for fixing brackets to solid concrete or masonry backgrounds. The safe working load is 30N per fixing, tested in concrete of characteristic strength of 30N/mm. When fixing to hollow backgrounds proprietary fixings will be necessary. Refer to.4.3 Robustness, Fixings into drywall systems. When lining timber joists, Gypframe GL or GL6 Timber Connectors should be fixed to the joists to support the channels at maximum 00mm centres. Services The cavity above the metal framework facilitates the incorporation of services. Pipes and conduits should be fixed in position before installing the framing. Where lighting fittings, access panels and similar components are incorporated as part of the design requirements, consideration must be given to maintaining the integrity of the ceiling to meet fire resistance and sound insulation requirements. Reduced support centres may be necessary to carry imposed loads. Contact the British Gypsum Drywall Academy Advice Centre for guidance. Refer to. Service installations. Fixtures Fixings to the system should always be made into the channels or to supplementary framing. Where heavy loads are anticipated, independent suspension should be provided from the structure. Board finishing Refer to 0 Finishing systems and decorative effects. Please refer to - Basic principles of system design for general guidance. 300
