RockLink 24 Monolith is characterised by quick
installation compared to existing concealed grid
systems. This is due to the lower number of
components and fixings.
RockLink 24 Monolith also provides easy access
to services due to its demountability.

Description
RockLink 24 Monolith is a concealed grid
suitable for the installation of Rockfon tiles
with edge detail D in module size 600 mm
x 600 mm. It comprises main runners, cross
tees, hangers, perimeter trims and a variety of
accesso­ries. RockLink 24 Monolith can be either
suspended or directly fastened to the soffit using
a variety of hangers. Tiles installed in this system
are fully demountable. See installation and
demounting instructions for full details.

Cross tee
After the grid has been installed, tile installation
is commenced by positioning the first tile (Tile
1) between two cross tees so that one side of
the tile with edge detail C is locked on the main
runner.
The remaining tile (Tile 3) is positioned in the
middle be­tween the two cross tees. This tile (Tile
3) is fully demountable.
The same principle is used for the installation of
the next tile (Tile 2) in the opposite end of each
1800 mm x 600 mm “bay”.
Demountability
The middle tile (Tile 3) in every 1800 mm x 600
mm bay re­mains fully demountable after finished
installation. To de­mount the middle tile, press up
carefully at the centre of the tile until it becomes
loose and can be re­moved. The other two tiles
can then be removed by pulling them free from
the main runners and lifting them out.

Perimeter finish options
Here are some options for perimeter finishing:
Perimeter trim should be installed 10 mm lower
than the grid system. Wall clips should be
positioned along the cut edges of perimeter tiles.
For options 1 - 4, it is important that the tiles
are cut 15 mm less than the distance from the
vertical face of the perimeter trim to the grid.
1.Angle trim
2. Shadow batten and angle trim
3. Shadow moulding
4.Timber (or similar) trim
When using direct hangers, the cut and
shortened cross tees should be installed
successively in order to ease installation.

Finishing options with MF plasterboard borders
Rockfon RockLink 24 Monolith can be
finished with MF plaster­board borders
and remain fully de­mountable. However,
it is important that the MF plasterboard
border is set out and constructed so as
to allow full size tiles to be used. When
setting out, always use as many “full”
1800 mm x 600 mm “bays” as possible.

Service integration
A variety of service installations and lights can
be easily inte­grated into this system and Rockfon
ceiling tiles.
When installing services, there may be a need
for additional hangers. This will depend on
the weight and position of the services. The
following guide­lines should be observed.
The ceiling tile alone should not support service
installations. Lightweight Installation loads should
always be adequately spread on the back of the
tile using thin metal yokes and the insertion of
angle splines. See illustrations on this page and
figure D4. Services exceeding 500 g in weight,
eg. Recessed modular luminaires should always
be independently supported, or additional
hangers should be positioned at the centre of
the 1800 mm cross tees as illustrated below.

Light installation details
See datasheet for guideline concerning lighting
installation. When integrating recessed modular
luminaries, it is important to ensure that the
1800 mm cross tees supporting the luminaire are
fitted with additional hangers. Alternatively, the
luminaire should be independently supported.
These luminaires should have a nominal face
dimension of 598 mm - 599 mm and a flange
width which exceeds 24 mm. These are available
from leading lighting manufacturers.

Installation guide
Perimeter Finishing
Tile installation
Junction between ceiling and wall or other
vertical surface
The perimeter trim should be fastened to vertical
surfaces at the required level using appro­priate
fixings at maximum 450 mm centres. The perimeter trim should be positioned 10 mm below
the grid system. 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 300 mm.
Install tiles as shown in figure D1. Refer also to
the installation sequence section.The wearing of
gloves is recommended in order to avoid soiling
the tiles.
Junction between ceiling and curved
vertical surface
The use of a preformed curved perimeter trim
is the most appro­­priate method. This should be
installed as described above. Rockfon can provide
details of curved perimeter trims on request.
Corners
Perimeter trims should be neatly mitred at all
corner joints. Overlap mitres are acceptable on
metal trims on internal corner joints unless specified otherwise.
Main grid
Unless specified otherwise, the ceiling should
be set out symmetrically and where possible,
perimeter tiles should be greater than 200 mm
in width.
The hangers should be fastened with appropriate
top fixings and to the main runners at 1200 mm
centres. Main runners should be positioned at
1800 mm centres and levelled at the appropriate
ceiling height. Main runner joints should be staggered and there should be a hanger positioned
within 150 mm of the fire expansion joint and
within 450 mm 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 should
be used to lock the hanger on to the bulb of the
main runner.
600 x 600 mm module
Fit 1800 mm cross tees between the main runners at 600 mm centres.
When using cut tiles at the perimeter, wall clips
should be positioned on the perimeter trim as
shown in fig. D2. The tile is pushed towards the
spring, then lowered down on to the grid.
The clip will push the tile into position and form
a tight joint. Where there is enough space in the
ceiling void, the perimeter tiles can be installed
with wall clips by gaining access through the
penultimate row of tiles. The penultimate row of
tiles should then be installed last of all.
Angle splines
Angle splines should be inserted in the tile edge
detail C when the tiles are loaded from the rear
side, e.g. with light fittings and loud­speakers or
when the ceiling is being used for fire protecting /
fire resisting purposes. See figure D4.
Fire Resisting / Protecting Ceilings
This system can be used in conjunction with
Rockfon Sonar tiles to create a 30 minutes fire
resisting / protec­ting ceiling construc­tion in
accordance with BS 476.
Enhanced Corrosion Resistance (ECR)
This system provides excellent longevity, however, it is also available in an enhanced corro­sion
resistant (ECR) format for use in harsh environment applications eg. swimming pools.
Rockfon tiles are easy to cut by using a sharp
knife. Edge paint should be applied to any visible
cut edges.
Direct fixing
Fasten the main runners to the structure by
means of direct hangers at 1200 mm centres,
see figure D3. As a minimum, every other direct
hanger should have a fixing nail used to lock the
hanger onto the bulb of the main runner. Ensure
that the ceiling is levelled at the appro­priate ceiling height as described above.
Fig. D1

Accessories
Fig. D2
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 Fixings
Top 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.
