Description
A CLADDING SUPPORT MEMBER
The present invention relates to support member and assembly for rboards which
includes a head ng portion.
Background to the Invention
Weatherboards are used as exterior cladding in many countries.
Weatherboard cladding requires a closure beneath the lowermost weatherboard. The closure
must be capable of excluding vermin such as rats and mice, but must still allow for air to
circulate into the space behind the weatherboards. The closure component must also be
installed level.
In order to support the lowermost rboard at the correct angle. timber wedges are typically
cut to suit. This can be time consuming.
Similar procedures are required for the weatherboard which is installed immediately above a
window. However, the lation of this weatherboard is further complicated by the need to
correctly install a head flashing over the window.
The reference to any prior art in the specification is not, and should not be taken as, an
acknowledgement or any form of suggestion that the prior art forms part of the common general
dge in any country.
Object of the Invention
It is an object of the present invention to provide a cladding support member and/or a method of
installing a weatherboard which will overcome or ameliorate ms with such support
members and/or s at present, or at least one which will provide the public with a useful
choice.
Other objects of the t invention may become apparent from the following description,
which is given by way of example only.

Brief Description of Preferred Embodiments
Referring first to Figures 1 — 4, a ciadding support assembly according to one embodiment of
the t invention is generally nced by arrow 100. The ment shown in Figures
1-4 is adapted for use in a “direct fix” construction, rather than a cavity construction.
The cladding support assembly 100 comprises a substantially uniform elongate cladding
support member 101 comprising an attachment portion 1 which can be penetrated by a ity
of fasteners when in use, to connect the support member 101 to a frame of a structure. The
support member 101 is ably a y body, more preferably an extrusion. In preferred
embodiments the support member may be made from aluminium.
The support member 101 further comprises a cladding support portion 2 which is connected to
the attachment portion 1 by a connecting portion 3.
The support member 101 further comprises a flashing portion 4. The flashing portion 4
comprises a capping portion 5 and a window frame overlap portion 6.
Each of the attachment portion 1, cladding support n 2, g portion 5 and window
frame overlap portion 6 are preferably generally planar, and of ntially constant thickness.
ing next to Figures 2 and 2A in particular, an outer face 2A of the cladding t portion
2 forms an angle A of between 6° and 9° to an outer surface 1A of the attachment portion 1,
most preferably around 8°.
The distance D between the centre of the outer face 2A of the cladding support portion 2 and
the outer face 1A of the attachment portion 1 is typically between 25mm and 35mm, preferably
around substantially 30mm, for embodiments which are to be used with a cavity spacer, and
between 5mm and 15mm, preferably around substantially 10mm for embodiments which are
used without a cavity spacer.
The capping portion 5 extends from the attachment portion 1 at an angle B of between 100° and
110°. most preferably at substantially 105°.
The window frame overlap portion 6 extends from the capping portion 5 at an angle C of
between 100° and 110°, most ably at substantially 105°. The window frame overlap
portion 6 is preferably substantially parallel to the outer surface 1A of the attachment portion 1.
The window frame overlap portion 6 preferably comprises an outwardly extending lip 7. The
lip 7 is preferably substantially parallel to the capping n 5.
Referring back to Figures 1 to 4, an end cap 8 may be provided to cap the sides of the support
member 101 in use. The end cap 8 may be adapted to fit into the space between the
ting portion 3 and the capping portion 5 in an interference fit, as best seen in Figure 1.
The end cap 8 may comprise an outer face 9 which overlaps the ends of the connecting portion
3 and capping portion 5. In preferred embodiments the ly 100 comprises an end cap 8
at either end of the support member 100.
Referring next to Figure 4 in particular, the connecting portion 3 is ably substantially
continuous, but comprises a plurality of ventilation res 10 therethrough.
The ventilation res 1 0 ably have a cross-sectional area of at least 1000mm2 of
cross~section open area per metre of length of the ng support member, but are preferably
sufficiently narrow that vermin such as rats and mice cannot pass through them.
Referring next to Figure 5, a cladding t member 101 is shown installed on a frame
member 20 of a structure, above a window frame 21. The cladding support member 101 is
lly installed such that its longitudinal axis is substantially horizontal.
The cladding t member 101 is mounted to the frame member 20 by means of suitable
fasteners, typically nails 22, which are driven through the attachment portion 1 and into the
frame member 20. The support member 101 is mounted such that the window frame overlap
portion 6 overlaps the top of the window frame 21 by at least 10mm.
A suitable sealing tape or building underlay product 23 is preferably used to seat the top of the
attachment portion 1.
A bead of suitable sealant is provided along the outer surface 2A of the cladding support
portion 2. A weatherboard 24 is then fastened to the frame 20, with its inner surface 24A resting
on the cladding support portion 2. The weatherboard is led such that a gap of at least
5mm is provided between the lower surface 248 of the weatherboard and the capping portion 5
of the flashing portion 4. This ensures a le space for air to flow to and from the ventilation
apertures 10.
Referring next to Figure 6, the installation procedure for installing a cladding support member
101A which is adapted for use with a cavity wall construction is ntiaily the same as that
described above with reference to Figure 5, with the exception that a cavity batten 25 is installed
after the support member 101A, but before the first weatherboard.
Those skilled in the art wilt appreciate that the present invention provides a ng support
3O member which provides a suitable window head flashing, a ventilated vermin strip, and a
support for a weatherboard or r cladding.
Unless the context clearly requires otherwise, throughout the description and the claims, the
words “comprise", “comprising”, and the like, are to be construed in an inclusive sense as
opposed to an exclusive or exhaustive sense, that is to say, in the sense of "including, but not
limited to".
Where in the foregoing description, nce has been made to specific components or
integers of the invention having known lents, then such equivalents are herein
incorporated as if individually set forth.
Although this invention has been described by way of example and with reference to possible
embodiments thereof, it is to be understood that modifications or improvements may be made
thereto without departing from the spirit or scope of the invention.
