The panel shall be mounted by tongue and groove mechanism using inside clip on aluminium extruded keel made of Grade 6063-T5 having dimensions 3000(L) x 24(H) x 15.5(W).The keel shall also be used for transition of the butt end of adjacent panel at every 7.2m. INSTALLATION:An appropriate vapour barrier (by others) shall be applied/installed on the vertical surface before the installation to properly seal against entry of any moisture. Vapour barrier (by others) shall be installed as per Manufacturer’s recommendation. Install wooden batten grid (provided by others) of section 50x50mm or as approved by the Architect on the solid wall/partition to provide level and plumb surface for fixing Keel. Install Keel vertically using screws and plugs at spacing of not more than 600mm centre-to-centre. The first and last keel should not be more than 150mm from the ends. Trim the tongue of the first bottom panel and install using headless nail with groove side upward. Subsequent panels are installed with tongue side downward by engaging with each other using tongue and groove mechanism and secured by inside clip. Continue this process until required height is achieved. Shorter butt edges need to be joined using industrial/wood glue. The keel shall also be used for transition of the butt end of adjacent panel at every 7.2m.  Install the Skirting (provided by others) of width 50mm or more as required by the Architect/ Engineer-in-Charge.  Finish off the edges using wooden moulding of matching colour (by others). Installation should be carried out as per Manufacturer recommended procedure complete all as specified and directed.  MAKE - KNAUF CEILINGS SOLUTIONS, TOPAKAUSTIC,  SAINT GOBAIN OR EQUIVALENT IN APPROVED MAKE LIST
