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

INSTALLATION OVERVIEW
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.
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.

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. Refer to Casoprano product
literature, available to download from www.gypsum.ie
