KOROK® INTERTENANCY APARTMENTS SYSTEMS www.korok.com 0800 773 777 .17APARTMENT INTERTENANCY SYSTEMS INSTALLATION VERTICAL INSTALLATION 1 Vertical installation of the KOROK® panels requires the C-track to be fixed to the supporting structure, e.g. walls, columns, portals, soffits and slabs. Plan your setout. 2 To ensure the C-track is sealed to the structure, a continuous bead of fire rated sealant is run around the perimeter before the C-track or Angle sections are laid and fixed. Or the sealant can be applied directly to the C-track before fixing in place. 3 Using a masonry drill bit, pre-drill the C-track at 400mm centres. 4 Then use the fixings to secure the C-track. .18 KOROK® INTERTENANCY APARTMENTS SYSTEMS www.korok.com 0800 773 777
APARTMENT INTERTENANCY SYSTEMS INSTALLATION 5 If the surrounding surface is uneven or if you’re not sure you have a good seal, add a continuous bead of fire rated sealant around the perimeter of the C-track where it contacts the surrounding surface. 6 KOROK® panels must be cut 20mm shorter than the structural opening measurement to allow for fitting. Pull back a 300mm section of the strippable film on the ends of the panels before placing the panels in to the C-track. Ensure that the first panel is plumbed vertical after fitting into the C-track. Screw fix the panel into place to the C-track. Subsequent panels are placed in a tilt and snap action. 7 Ensure the tongue and groove are fully locked to maintain the fire and acoustic performance. Remove strippable film at the end of each day’s work. 8 CUTTING OF KOROK® PANELS KOROK® panels can be cut to length and width with the use of a reciprocating saw or a radial saw with dust extraction. Diamond cutting discs are recommended for radial saws. Where KOROK® panels are trimmed to width, the cut edge of the panel is fitted into the C-track and so is always the last panel abutting the wall or column. The panel is then sealed and fixed in position as usual. KOROK® INTERTENANCY APARTMENTS SYSTEMS www.korok.com 0800 773 777 .19
