Upgrading existing timber joist floor (ceiling retained) 1. Set out GTEC Dryliner Track RD9 as steps overleaf 2. Set levels, mark the centre line of each joist on the existing ceiling, and secure GTEC SR Brackets RD2 to joists with two 32mm GTEC High Thread screws with spacing as table 2. Fold down the legs after fixing. 3. Locate the GTEC Dryliner Channel RD1 as step 3 overleaf. Existing Ceiling GTEC Dryliner Bracket into joist Mineral Wool Insulation 4. Secure the GTEC Dryliner Channel to each leg of the GTEC SR Bracket RD2 with GTEC Pan Head Self Tapping screws 11PHST500. Where necessary bend back the legs of the GTEC Dryliner GTEC SR Bracket if they protrude past the face of the channel. GTEC Dryliner Channel 5. Install the mineral wool insulation and plasterboards as steps 4 and 5 overleaf. Concrete Soffit GTEC Dryliner Bracket Mineral Wool Insulation GTEC Dryliner Channel <strong>Installation</strong> to Concrete Floor Slab 1. Fix the GTEC Dryliner Track RD9 at 600mm centres to perimeter walls allowing for required cavity/ceiling height. 2. Mark horizontal lines at 400mm or 450mm maximum centres on the underside of the slab to locate GTEC Dryliner Channels RD1. 3. Position the GTEC Dryliner SR Brackets RD2 directly to underside of the slab along marked lines (see table 2). Fold down the legs and secure to underside with suitable fixing through horizontal slot. 4. Cut the GTEC Dryliner Channel RD1 5mm shorter than the length of the ceiling required and locate the Dryliner Channel RD1 into GTEC Dryliner Track. 5. Ensure the GTEC Dryliner Channel RD1 is level. Secure GTEC Dryliner Channel RD1 to each leg of GTEC SR Bracket using GTEC Pan Head screws 11PHST500. Where necessary bend back the legs of the GTEC SR Bracket if they protrude past the face of the channel. Where the ceiling length exceeds channel length, connect two lengths of channel together with GTEC Dryliner Channel Connectors RD3. 6. Where required insert mineral wool insulation above the framing ensuring that the mineral wool forms one continuous lining. 7. Fix the plasterboards with long edges at right angles to GTEC Dryliner Channels RD1, butt firmly against the perimeter and fix to the framing with GTEC Self Tapping screws at 230mm maximum centres and 150mm maximum centres at perimeter and cut end of the plasterboard. Butt edges lightly against each other and centre edges of the plasterboard over the channels. THE INSTALLATION HANDBOOK 2008 57
