NB Figures quoted for sound insulation refer to room-to-room tests to BS EN 20140-9. Where higher levels are required other design considerations can be
adopted, such as extending partitions into the ceiling void or installing a plenum barrier.
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.
See Construction details – 1 - 8 for alternative configurations.
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 occupied buildings in conditions
up to 90% relative humidity (RH90). However, Gyptone tiles
and planks are only suitable up to RH70.
Cavity barriers
Where cavity barriers are required, they can be formed using
Gyproc FireStop screw-fixed to a simple metal 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.
Fixtures
Unperforated Gyptone ceiling tiles will support a point load
of up to 3kg / tile for maximum 2mm deflection (1kg / tile for
D2 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 Gyptone ceiling tiles using a circular tank cutter on a
power drill or using a pad saw.
190
The Gyptone T24D2 grid should not be point-loaded with
more than 1kg 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 installed in the Gyptone TI5 grid 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
can be re-decorated if required using a suitable emulsion
paint and a short-haired brush or roller (spray painting will
impair sound absorption).
Gyptone tiles with Activ’Air
Though we don’t notice them, impurities are often present in
the air we breathe – emitted from furniture, carpets and
building materials. Long-term exposure to these can
potentially cause health problems and reduce general
wellbeing.
Clean air, on the other hand, can speed up patient recovery in
hospitals, reduce absence at work, and increase pupils’
concentration at school.
Activ‘Air is our latest innovative technology that improves
indoor air quality by permanently removing formaldehyde
circulating indoors. Formaldehyde concentration will be
reduced by 70% when 1m2 of Activ’Air is installed per m3.

When installing the Gyptone edge D2, use cotton gloves.
Lift one side of the tile, the E edge, up above the cross profile.
Then slide the opposite side of the tile, the D2 edge, into the
opposite cross profile. When the tile is mounted in the grid
system, it can be slide into place. Be careful not to damage
the tiles during installation. All tiles a demountable after
installation. All installations should be finished before
mounting the D2 tiles. Always start in the center of the room,
when laying the tiles into the grid system.

Adjust the entire grid system, so the cross profiles is laying on
the top step of the shadow moulding, like seen in the lower
right corner. This means that the main profiles are located
above the shadow moulding. Ones the grid system is adjusted,
every second main beam should be connected to the wall for
stability. This is done with an connecting bracket.
I
When installing the Gyptone Xtensiv, use cotton gloves. Lift
one side of the Xtensiv up above the grid system. Then there is
enough space to lift the other side of the Xtensiv up, laying it
in place on the opposite cross profile. All installations should
be finished before mounting the Xtensiv plates.
J
It is possible to slide the Xtensiv along the cross profiles, ones
it is in place in the grid system. This is needed when installing
the Xtensiv plates in the perimeter of the room.
K
Gyptone Xtensiv can be shortened with a knife. It is possible
to shorten the Xtensiv by cutting in the perforated area, if it is
necessary. It is not recommended to cut in the perforated area
of an Xtensiv Line, as cutting into the Line perforation will
weaken the Xtensiv.
L
In case lighting fittings are planned, supporting profiles have
to be mounted using the light fitting XT. This bracket is needed
to give the Xtensiv ceiling the same visual appearance regarding
the light installation, as the photo on the front page of the
installation manual. The position of the brackets is related of
the light fitting and ceiling layout. The light fitting XT needs
to be secured with Gyproc Wafer Head Screws. To support the
cut in the main beam, place a hanger near the light fitting XT.
It is also possible to make a 600x600 mm recess, for a light
fitting in the Xtensiv ceiling system. The method is shown on
page 198. Page 198 shows the 2 possible connections
between the cross profile and the cross tee. In case of a square
recess in the Xtensiv ceiling, the recess should be placed between the main profiles and not under the main profiles.
