INSTALLATION 1 Mark position on walls for desired clear space/ceiling height, taking into account the thickness and number of layers of plasterboards to be used. Fix the GTEC Dryliner Track RD9 to walls and around columns etc at 600mm maximum centres. Mark walls on the underside of the GTEC Dryliner Tracks that are parallel to joists for position of the GTEC Dryliner Channels RD1. Spacing as table 1. 2 Set levels and secure the GTEC Dryliner Joist Connecter RD5 or RD10, depending on cavity depth, to side of joist, on line of GTEC Dryliner Channel with two 32mm GTEC High Thread screws 32DHT1000 spaced as table 2. Ensure GTEC Joist Connectors are level. 3 Offer the GTEC Dryliner Channel to the GTEC Joist Connectors and twist to secure. Where necessary extend the length of the GTEC Dryliner Channel by connecting two lengths of GTEC Dryliner Channel together with GTEC Dryliner Channel Connector RD3. 58 THE INSTALLATION HANDBOOK 2008
4 Cut the GTEC Dryliner Channel RD1 5mm shorter than the length of the ceiling required and locate the GTEC Dryliner Channel RD1 into the GTEC Dryliner Track. Where required insert mineral wool batts above the framing ensuring that the mineral wool forms one continuous lining. 5 Fix plasterboards with the long edges at right angles to the GTEC Dryliner Channels. Screw-fix the boards to the GTEC Dryliner Channels at 230mm maximum centres and 150mm maximum centres at perimeters and the cut ends of board. With two layers of plasterboard, stagger all the joints between the layers. For the typical single layer and two-layer plasterboard layouts, see diagrams overleaf.
