CLADDING PANEL
Abstract
A composite cladding panel 1 comprises a backing tray 2 and an
external skin 3 with a layer of foam insulation 4 therebetween. A
plurality of spacers 10 are attached to the external skin 3. The
spacers 10 are of top-hat form with mounting legs 41 for mounting
to the skin 3 and a support 40 to which side edge clips 20 are
mounted. The clips 20 have spaced-apart formations 21 that engage
in corresponding side edge recesses 22 of tiles 5. The top hat
spacers 10 space the tiles 5 apart from the skin 3 of the panel so
that the tiles 5 define with the skin 3 ventilation passageways 30
which can remove moisture.

Description
INTRODUCTION
[0001] The invention relates to a composite cladding panel of the
type comprising an inner skin and an external skin with insulation
foam material therebetween.
[0002] Buildings comprising a steel frame on which pre-formed
panels are mounted may be erected quickly and more cheaply than
buildings with brick or block facades.
[0003] One of the problems with buildings constructed from
pre-formed panels is that such panels can often be uninteresting
aesthetically. It is known to form such panels with various
profiles and in various colours, however, there is still a need to
provide an aesthetically different facade in some cases. One such
system is described in our WO2006/064489A.
[0004] This invention is directed towards providing an improved
panel system of this type.
STATEMENTS OF INVENTION
[0005] According to the invention there is provided a composite
cladding panel comprising an internal skin and an external skin
with insulation material therebetween, one of the skins having a
plurality of spacers attached thereto, the spacers being adapted
for fixing tiles or the like to the spacers to form a cladding, the
tiles defining with the skin to which they are attached a
ventilation passageway.
[0006] In one embodiment the spacers comprise support elements.
[0007] The support element preferably comprises a mounting leg for
mounting to the panel and a support leg for receiving a tile
fixing.
[0008] In a particularly preferred embodiment the support element
is of top-hat form.
[0009] In one embodiment the support elements are attached to the
panel by a plurality of fasteners. The fastener may comprise a
clamping fastener. The clamping fastener may comprise an internal
sleeve and a bolt, the sleeve clamping to the inside of the
external skin on tightening of the bolt.
[0010] In one embodiment the external skin of the panel has an
adhesive on the inner face thereof. The adhesive may be applied to
the inner face of the external skin prior to lay-down of liquid
insulating foam reactants.
[0011] In one embodiment the panel comprises a plurality of tile
fixings attached to the spacers. In one case the tile fixings are
edge tile fixings.
[0012] In another aspect the invention provides a composite
cladding panel comprising an internal skin and an external skin
with insulation material therebetween, one of the skins having a
plurality of support elements attached thereto, the support
elements being adapted for fixing tiles or the like to the support
elements to form a cladding, the support element comprises a
mounting leg for mounting to the panel and a support leg for
receiving a tile fixing. Preferably the support element is of
top-hat form.
BRIEF DESCRIPTION OF THE DRAWINGS
[0013] The invention will be more clearly understood from the
following description thereof given by way of example only, in
which:
[0014] FIG. 1 is a perspective view of a composite insulating
cladding panel system according to the invention;
[0015] FIG. 2 is a cross-sectional view of the composite panel of
FIG. 1;
[0016] FIGS. 3 and 4 are cross-sectional views illustrating a
fastener used with the panel; and
[0017] FIG. 5 is a perspective View of the fastener, in use.
DETAILED DESCRIPTION
[0018] Referring to the drawings there is illustrated a composite
cladding panel 1 according to the invention. The panel 1 comprises
a steel skin or backing tray 2 and an external steel skin 3 with a
layer of foam insulation material 4 such as a phenolic or
polyurethane based foam material therebetween. The panel may be of
any suitable type such as that described in our UK2325678A, the
entire contents of which are hereby incorporated by reference.
[0019] One of the skins, in this case the external skin 3 has a
plurality of spacers for fixing facade or cladding elements such as
tiles 5 to the panel. The tiles may be brick, ceramic or the like
to form a cladding for the panel. The spacers comprise support
elements 10 and fasteners 12 for fastening the support elements 10
to the external skin 3.
[0020] Each fastener 12 comprises an internal clamping sleeve 15
and a bolt 16. One such fastening systems is that referred to in a
Fablok (Trade Mark). A hole is first drilled through the skin 3 and
the sleeve 15 is inserted as illustrated in FIG. 3. On tightening
of the bolt 16, the sleeve 15 splays and is clamped against the
inside surface of the external skin 3 as will be particularly
apparent for FIGS. 4 and 5. The support element 10 has pre-drilled
holes through which the shanks of the bolts 16 are inserted. On
tightening of the bolts 16, the support elements 10 are fixed to
the panels. In this way the support elements 10 are efficiently and
effectively clamped to the external skin 3. The support elements 10
are omitted from FIGS. 2 to 5 for clarity.
[0021] To enhance the peel strength of the composite panel a layer
30 of an adhesive is applied to the internal face of the external
skin 3. The adhesive layer 30 is a pre-lay-down adhesive which is
compatible with the material of the insulting core 4. We have found
that the use of such an adhesive greatly enhances the peel strength
of the panel and enables the panel to carry the additional load of
the cladding tiles.
[0022] In manufacture, an external skin 3 is drawn from a reel and
laid down in a lay-down bed with the internal face uppermost. The
adhesive 30 is then uniformly applied over the internal face of the
skin 3 prior to lay-down of liquid foam reactants. The inner skin 2
is then led from a reel and located above the liquid foam
reactants. The assembly is the passed through an oven in which the
liquid foam reactants expand to form the insulating core 4. A
desired length of panel is then cut.
[0023] The support elements 10 are laid out across the external
face of the skin 3 of the panel and the locations for fastening the
receiving boles to be drilled in the panel are marked. The support
elements may be removed, the holes drilled and the clamping sleeves
15 inserted. The holes in the support elements 10 are aligned with
the clamping sleeves 15 and the bolts are inserted and tightened,
clamping the support elements 10 to the skin 3 as described above.
The tiles 5 are then fixed to the support elements 10 using side
edge fixing clips 20 having spaced-apart formations 21 that engage
in corresponding side edge recesses 22 of the tiles 5. The tiles 5
are moved into place and held on the support elements 10. No fixing
screws are required to mount the tiles 5 to the support elements
10.
[0024] The invention provides a composite panel of relatively
simple but highly robust construction which facilitates easy on
site cladding with finishing tiles such as brick tiles.
[0025] In the invention the spacers 10 space the tiles 5 apart from
the skin of the panel to which they are attached. Thus, the tiles 5
define, with the skin 3 of the panel ventilation passageways 30.
These ventilation passageways 30 can remove moisture which is
particularly useful in the case of a porous facade or tile. The
ventilation gap defined by the spacers 10 is preferably at least 25
mm but can be at least 50 mm or possibly larger, depending on the
application.
[0026] It will be appreciated that a fire break can be provided
between the tiles and the panel to prevent fire travelling in the
gap therebetween. Such a fire break may be of an intumescent
material that expands only in a fire situation. Thus, ventilation
is not restricted in normal use.
[0027] The support elements 10 in this case have a support 40 to
which the tile fasteners/clips 20 are readily mounted and a
mounting leg 41 for mounting the support element 10 to the panel.
In this case the support elements are of top-hat shape which is a
particularly suitable form for this application because a top hat
section has two sidewardly projecting fixing legs. The top hat form
is a very stable section that lends itself to being fixed to flat
surfaces.
[0028] It will be appreciated that in use the panels may be
vertically orientated as illustrated in FIG. 1 which is
particularly suitable when ventilation is required. However, the
panels may be horizontally orientated. The top hat support elements
may also be vertically or horizontally orientated.
[0029] The invention is not limited to the embodiments hereinbefore
described which may be varied in detail.
