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/m2. Grid weight is inclusive; tile weight is not included.

Junction between ceiling and wall orother vertical surfaceThe perimeter trim should be fastened to verticalsurfaces 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 curvedvertical surfaceThe use of a preformed curved perimeter trimis the most appropriate method. This should beinstalled as described above. ROCKFON canprovide details of curved perimeter trims onrequest.

CornersPerimeter trims should be neatly mitred at allcorner joints. Overlap mitres are acceptableon metal trims on internal corner joints unlessspecified otherwise.

PERIMETER FINISHING

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 installationWe 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.

Unless specified otherwise, the ceiling shouldbe set out symmetrically and where possible,perimeter tiles should be greater than 200mmin width.

The hangers should be fastened with appropriate top fixings and to the main runners at 1200mm centres. Main runners should be positioned at 1200mm 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 shouldbe used to lock the hanger on to the bulb of themain runner.

ENHANCED CORROSION RESISTANCE (ECR)

FIRE RESISTING / PROTECTING CEILINGS

This grid provides excellent longevity and complies with the requirements of Class B BS EN 13964.

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 13964.

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 andapproved constructions, please contact ROCKFON.

Hold down clipsA variety of hold down clips suitable for usewith 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 1200mm edge.

In small rooms, entrance areas, staircases andother areas which may be subject to pressuredifferences between room and ceiling void, it isrecommended 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 FixingsTop 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 IntegrationA 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.
