Gypframe GL, GL9 or GL Brackets are fixed at the required centres. Gypframe GL Lining Channel is located into the perimeter track and each leg of the Gypframe GL, GL9 or GL Bracket is screw-fixed 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 GL 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. Installation overview - 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 GL Track at the perimeter. Gypframe GL Lining Channel sections are joined using Gypframe GL 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.

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. When using Gypframe GL Brackets, allow for a stand-off of mm 7mm plus the lining thickness. When using Gypframe GL9 Brackets, allow for a stand-off of mm mm plus the lining thickness. When using Gypframe GL Brackets, allow for a stand-off of mm 7mm plus the lining thickness. When fixing to timber joists using Gypframe GL or GL6 Timber Connectors, allow for a maximum cavity depth of mm 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 F 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 section 0 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. When fixing to hollow backgrounds proprietary fixings will be necessary. When lining timber joists, Gypframe GL or GL6 Timber Connectors should be fixed to the joists to support the channels at maximum 00mm centres for single layer boarding, and maximum 600mm centres for double layer boarding. 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 light 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. Refer to section. Service installations. Fixtures Fixtures with a maximum weight of kg, e.g. single lights, can be fixed into the channels. For other fixtures, independent suspension should be provided from the structure. Board finishing Refer to section Finishing systems and decorative effects.
