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.

Gyptone, Casoprano and Gyprex tiles

Wall Angle is fixed to the walls at 300mm centres. 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.

INSTALLATION OVERVIEW

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.

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

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

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).

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.

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.

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 fire-

stopping 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.

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. Refer to Casoprano product

literature, available to download from www.gypsum.ie
