Gyproc Lay-in Grid Ceilings Gyproc Lay-in Grid Ceilings Gyproc Lay-in Grid Ceilings are a lightweight ceiling system available in concealed or exposed grid options. They present an attractive pre-finished white ceiling and a range of decorative effects are possible by selecting the desired tile or plank edge profile and finish. Pre-finished tile options include smooth, textured, patterned or perforated effects. Pre-finished plank is available in smooth or perforated options. 1 2 Key facts 1 Main ‘T’ 2 Gyptone plank ● Concealed or exposed grid options ● Attractive pre-finished white surface ● Wide range of ceiling tiles and planks giving smooth, textured, patterned or perforated effects ● Provides sound attenuation and absorption ● Electrical and other services accommodated in plenum ● Will support loads up to 3kg per tile without a pattress 320 ✔ ✔ ✔ Resid e High ntial Rise Resid e Apar ntial tmen ts Resid e Hous ntial ing Enter tainm ent Custo dial ✔ Audit oria ✔ Indus trial ✔ Healt hcare ✔ Educ ation Retail ✔ Sport & Leis ure Comm ercial 6.6 Offic es Sector Guide ✔ F 00353 1 623 7054 E enquiries@gyproc.ie COMPONENTS Gypframe metal products Edge details Main Beam A Exposed grid E15 Recessed grid D1 Concealed grid 24mm Main ‘T’ section 15mm Main ‘T’ section Length 3600mm Gyproc Lay-in Grid Ceilings T 00353 1 629 8400 Cross ‘T’ 24mm Cross ‘T’ section 15mm Cross ‘T’ section Length 600, 1200mm Wall Angle 24 x 24, 24 x 19 and 19 x 19mm Wall Angles Length 3000mm Insulation products Shadowline Moulding Shadowline Moulding for Gyptone planks.

Main Beam sections are installed at 1200mm centres, suspended from the structural soffit at 1200mm centres along their length. Hangers should be located close to the intersection of the Main Beam and 1200mm Cross ‘T’ to facilitate demounting of the tiles from the grid. 1200mm Cross ‘T’s are installed at 600mm centres along the lengths of the Main Beam, followed by the installation of the 600mm Cross ‘T’ at the mid-point of the 1200mm Cross ‘T’ sections to form the 600mm x 600mm grid. ‘A’ and ‘E15’ edge type tiles are laid into the grid on a progressive basis, resting the tiles on top of the flanges of the ‘T’ sections. The D1 edge type tiles are installed using the metal sections on the back of the tile to key over the ‘T’ sections. Fit cut tiles next to the walls last at a maximum of 2mm from the wall. 6.6 322 Gyptone planks Shadowline moulding is fixed to the wall at 300mm centres. Reduce the Main ‘T’ sections by a maximum of 10mm, in relation to the width of the room or corridor and fit into the Shadowline moulding on the recessed flange. There is no requirement to install hangers to support the intermediate Main ‘T’ sections. Hangers may be required to support perimeter Main ‘T’ sections where two or more spanning sections adjoin. Main ‘T’ sections should not be joined. Gyptone planks are located on the lower flanges of the Shadowline moulding. F 00353 1 623 7054 E enquiries@gyproc.ie DESIGN Planning - key factors Ceilings should be set out from the centre to give balanced widths of tiles at the perimeter. A number of grid layouts are possible, depending on the grid selected and the choice of ceiling tile or plank. Designers and installers should take due regard of EN 13964, suspended ceiling - requirements and test methods. NB Relative humidity (RH) The grid is suitable for use in heated occupied buildings in conditions up to 90% relative humidity (RH90). Casoprano and Gyprex tiles are suitable up to RH90 and Gyptone tiles and planks up to RH70. Fixtures Unperforated Gypsum Industries ceiling tiles will support a point load of up to 3kg / tile for maximum 2mm deflection (1kg / tile for D1 edge tiles). This will normally allow items such as spotlights and down-lighters to be installed without the need for a support pattress. A support pattress should, however, be installed where the prevailing environmental Gyproc Lay-in Grid Ceilings T 00353 1 629 8400 conditions exceed 25°C and RH70, or where the size of the cut-out required is greater than 150mm diameter or 150mm square. Perforated tiles should not be used to support fixtures. Apertures for spotlights and down-lighters can be cut into Gyproc ceiling tiles using a circular tank cutter on a power drill or using a pad saw. When using D1 edge tiles, the grid should not be point Cavity barriers Where cavity barriers are required, they can be formed using Gyproc FireLine or Glasroc F Multiboard screw-fixed to a simple metal or timber frame. The framing should be fixed to the structure to avoid undue loading of the ceiling suspension grid. The bottom of the framework should be fixed to the ceiling grid. Fire-stopping It is necessary to provide suitable non-combustible firestopping material at the junction of a cavity barrier with the structural perimeter and the ceiling. Fire-stopping must also be provided around any service penetrations through the cavity barrier. Water vapour control The surface of Gyprex tiles has a water vapour resistance of 45MNs/g. Whilst the vinyl surface can provide an effective vapour control layer, it may be necessary to complete the integrity where the boards abut metal grid sections. This is achieved by sealing with continuous beads of water vapour resistant mastic, which should be applied to the back of the metal sections prior to inserting the tiles. Care should be taken to ensure that the mastic sealant does not damage the vinyl surface of the tiles. loaded with more than 0.5kg between points of suspension. Distributed loads may be max. 2kg/m of section. Built-in light fittings that are placed between grid sections are suspended separately. Gyptone plank must not be loaded. Light fittings and other fixtures should be independently supported. If mineral wool is placed above the ceiling, the maximum self supporting distance is reduced to 1800mm. Hangers should be used for increased spans. Services The ceiling void above the suspension grid can be used to route all service requirements including ducting, pipework, electrical cables, and conduits. Ducting, ventilation units, etc, must be independently supported from the structure. Maintenance Ceiling tiles and planks can be cleaned using a damp cloth or soft brush. Most standard mild detergents can be used. Tiles other than Gyprex can be re-decorated if required using a suitable emulsion paint and a short-haired brush or roller (spray painting will impair sound absorption). Other precautions, such as cavity ventilation, may be necessary to reduce the risk of interstitial condensation. Speech clarity In order to achieve optimum speech clarity throughout an entire room environment, Casoprano voice (sound absorbing) and Casoprano forte (sound insulating) tiles can be used in combination without changing the visual appearance of the ceiling area.
