Depth when using direct hangers is minimum 50mm. SYSTEM LOADING CAPACITY Kg/m² Maximum deflection Hanger distance (mm) Module size (mm) 2.5mm 3.3mm 4.0mm 600 x x The system loading capacity is determined based on a maximum deflection of each component equal to 1/500 of the span or the cumulative deflection of all the structural components which do not exceed 4mm. The loading capacity is shown as evenly distributed load in kg/m 2. Grid weight is inclusive; tile weight is not included.

7 For general installation guidance, refer to the ROCKFON Installation Guide for: Chicago Metallic T24 Click 2890 Chicago Metallic T15 Click 2790 PERIMETER FINISHING Junction between ceiling and wall or other vertical surface The perimeter trim should be fastened to vertical surfaces at the required level using appropriate fixings at nominal 450mm centres. Ensure that butt joints between adjoining lengths of trim are neat and that the trim is free from kinks and remains true and level. For the best aesthetics, use as long a length of trim as possible. The minimum recommended cut length is 300mm. Timber trims, timber shadow battens and metal shadow mouldings should not be used with fire resisting/protecting ceilings. Junction between ceiling and curved vertical surface The use of a preformed curved perimeter trim is the most appropriate method. This should be installed as described above. ROCKFON can provide details of curved perimeter trims on request. Corners Perimeter trims should be neatly mitred at all corner joints. Overlap mitres are acceptable on metal trims on internal corner joints unless specified otherwise. MAIN GRID Unless specified otherwise, the ceiling should be set out symmetrically and where possible, perimeter tiles should be greater than 200mm in width. The hangers should be fastened with appropriate top fixings and to the main runners at mm centres. Main runners should be positioned at mm centres (900mm centres for 900mm x 900mm tiles) and levelled at the appropriate ceiling height. Main runner joints should be staggered and there should be a hanger positioned within 150mm of the fire expansion point and within 450mm of the end of the main runner where it terminates at a perimeter. Additional hangers may be necessary to support the weight of ceiling services. When using direct hangers, a fixing nail should be used to lock the hanger on to the bulb of the main runner. mm x mm module Fit mm cross tees between the main runners at mm centres. mm x 900mm module Fit mm cross tees between the main runners at 900mm centres. mm x 600mm module Fit mm cross tees between the main runners at 600mm centres. 600mm x 600mm module As mm x 600mm module but intersect mm cross tees with 600mm cross tees at mm centres parallel to the main runner. 900mm x 900mm module Fit 900mm cross tees between the main runners at 900mm centres. 900mm x 600mm module Fit mm cross tees between the main runners at 900mm centres, intersect with 900mm cross tees at mm centres parallel to the main runner. TILE INSTALLATION ROCKFON tiles have a matt white or coloured surface and are directional. To ensure a consistent appearance to the finished ceiling, it is important that all tiles are installed in one direction, indicated by the arrow printed on the back of the tile. Tile installation We recommend the use of clean nitrile or PU coated gloves when installing ROCKFON tiles in order to avoid fingerprint marking on the surface. For an optimum work environment, we recommend installers always observe common work practices and follow installation advice as shown on our packaging. ROCKFON tiles are easy to cut by using a sharp knife. Apply ROCKFON edge paint to any visible cut edges. 7

8 FIRE RESISTING / PROTECTING CEILINGS This system can be used in conjunction with many ROCKFON ceiling tiles to create a variety of specifically designed fire resisting/protecting ceiling constructions. Many ROCKFON ceiling solutions have been tested and subsequently independently assessed in accordance with BS 476 Parts 21, 22 and 23. For further details of the tiles, module sizes and approved constructions, please contact ROCKFON. ENHANCED CORROSION RESISTANCE (ECR) This grid provides excellent longevity and complies with the requirements of Class B BS EN Chicago Metallic grids are also available in an Enhanced Corrosion Resistant (ECR) format for use in harsh environments such as swimming pools. Our ECR grids comply with the requirements of Class D BS EN ACCESSORIES Hold down clips A variety of hold down clips suitable for use with the many ROCKFON tiles are available for this system. For fire resisting/ protecting ceilings, tiles should be clipped at the rate of 2 clips per 600mm edge and 3 clips per mm edge. In small rooms, entrance areas, staircases and other areas which may be subject to pressure differences between room and ceiling void, it is recommended to alleviate pressure build up with the use of vents or grills. Alternatively, in some situations, clips can be used to secure the tiles into the grid system. Hangers Wire and adjustable rod hangers should be fastened through the holes in the stalk of the main runners. Wire hangers should be passed through the hole and wrapped at least three times around itself. Adjustable rod hangers should be orientated and connected to main runners so that the lower sections of the hangers run in the same direction. Top Fixings Top fixings are available from many specialist suppliers. It is important to be sure that the top fixings used to support the ceiling are appropriate for the specific soffit and that they provide adequate pull out strength when installed. Service Integration A variety of service installations and lights can be easily integrated into this system. Service installations should not be supported on the ceiling tile alone. Service loads should always be adequately spread on the back of the tile or transferred to the grid system using appropriate support arms or yokes. Alternatively, the service should be independently supported. Please contact ROCKFON Technical Support for further advice. 8
