Description

Cross-Reference to Related Application

[0001] This application claims priority to Australian provisional patent application 2025900869 filed 18 March 2025, the entire contents of which are hereby incorporated by reference. Technical Field

[0002] The present invention relates to the field of building cladding. For example, exterior cladding such as wall or roof cladding panels secured to a building structure such as an underlying building frame structure. Background of Invention

[0003] The following discussion of the background to the invention is intended to facilitate an understanding of the invention. However, it should be appreciated that the discussion is not an acknowledgement or admission that any of the material referred to was published, known or part of the common general knowledge as at the priority date of the application.

[0004] Building cladding is commonly used in construction to provide at least one of weatherproofing, insulation or aesthetic appeal to a structure or building. Building cladding typically comprises elongated panels of coated steel sheeting installed in side-by-side or in overlapping configuration such that a side edge of a panel overlaps or underlaps the side edge of an adjacent panel.

[0005] Cladding panels may be mounted to an underlying support structure such as a row of battens or joists using screws or similar fasteners. The visual effect of fasteners is generally considered aesthetically detrimental to a cladding system. Fasteners used for wall cladding (as compared to roof cladding) are especially undesirable because wall cladding fasteners are more observable and are therefore considered particularly detrimental to building aesthetics.

[0006] In response to this issue, wall cladding has been developed which uses an interlocking configuration designed to reduce or eliminate the need for fasteners and thereby 2026201962   16 Mar 2026 improve system aesthetics. Examples of existing interlocking cladding systems are disclosed in the patent literature and, for example, in AT16090, AU2013101367, US2016 / 0145872, AU2020100448 and AU2021221756.

[0007] A drawback with some existing interlocking cladding systems is that one or both sides of the cladding panel is not anchored directly to the structure and is secured only via interlocking engagement with an adjacent panel. This compromises panel security and, depending on panel stiffness, it is possible for wind to induce sufficient flex in a panel to lift and disengage a panel side from its interlocking engagement. The risk of wind-induced panel disconnection is increased with the use of lighter gauge (less stiff) steel panels which are generally preferred for reduced transport costs and material consumption.

[0008] As well as exposing the underlying structure to damage from wind and rain, a cladding panel disconnected at one side can flap in the wind causing damage or deformation to the panel and / or to adjacent panels and / or to the building structure. It can also cause a knock-on effect of sequential panel disconnection.

[0009] A further issue with some existing interlocking cladding panel systems is that they rely on a ‘snap-lock’ interlocking engagement which relies on resilient deformation of the panels to achieve interlock with the adjacent panel. As snap-lock panels are assembled on site by an installer, the force required to engage the panels is limited by what an installer can reasonably apply in a repetitive manner to install a series of adjacent panels. This introduces a design limitation whereby the physical strength of the snap-lock connection must be sufficiently low to allow for convenient installation. In some instances, this leaves systems vulnerable to deformation or disconnection under wind loading.

[0010] A further drawback with some existing interlocking cladding panel systems is that during installation, deformation of a preceding panel lap occurs as each subsequent panel lap is pressed into engagement by the installer. The preceding panel is necessarily deformed which may cause incorrect engagement of the preceding panel. This issue may be exacerbated or is most apparently at a mid-span position of the panels (e.g. between frame members of the building structure) where the panels are unsupported and therefore most vulnerable to deformation. 2026201962   16 Mar 2026 Summary of Invention

[0011] It is desirable to provide a novel cladding panel system which provides an improvement over existing systems and / or provides an alternative choice for consumers or cladding installers.

[0012] Before turning to a summary of the invention, it is useful to provide an explanation of some of the terms that will be used to define the spatial relation of various parts thereof. Spatial references throughout this specification will generally be based upon a wall or roof cladding installation in which cladding is mounted to an underlying structure, for example a wall joist, frame member, roof batten or ply board base structure. With this environment as the basis, some parts may then be defined with reference to the cladding. For example, an object which is "underneath' or "beneath" the cladding will be understood as being on an internal side of the cladding and not necessarily 'below' in terms of vertical elevation, although the object may also be vertically lower in the instance of a roof installation.

[0013] Further, it will be understood that cladding panels have an interior and an exterior and thus some parts may be defined with directional reference to "inner", "inwardly", "outer", "outwardly", "upstanding" with respect to the interior of the cladding panel. It should be appreciated that cladding panels can also be installed within a building interior and therefore a reference to "exterior" refers to the exterior side of the panel and not necessarily to the outside of a building or structure. The term ‘upstanding’ will be understood as extending from a reference surface such as the surface of building frame or structure and is not limited to a vertical orientation. In the context of wall cladding, a component may be mounted to, and be upstanding from, a vertical surface of a wall frame member. In this instance, the upstanding component could extend in an approximately horizontal orientation.

[0014] Additionally, it will be understood that a cladding panel typically comprises a generally planar fascia portion extending between a pair of sides. In this regard, references herein to a 'side' or ‘side portion’ of a panel will be understood as referring to the opposite sides of the panel (which also comprise the side edges) and not to the inner and outer surfaces of the fascia panel. Where a cladding panel is generally rectangular in profile, the 'sides' or ‘side portions’ of the panel refer to the opposite longitudinal sides which are located adjacent to or which overlap to the sides of an adjacent cladding panel, in a side-by-side installation 2026201962   16 Mar 2026 configuration. The ‘sides’ or ‘side portions’ extend between opposite ‘ends’ and references herein to panel ‘ends’ will be understood as the edges of a panel which extend between the opposite longitudinal sides.

[0015] According to an aspect of the invention, there is provided a building cladding system, comprising: at least one support member mountable to a building; first and second cladding panels each having a pair of opposite first and second side portions configured to be mounted to the support member and having profiles complementary to a profile of the support member at least one fastener for fastening the first and second side portions relative to the support member; a capping member mountable in a mounted position covering the fastened side portions to visually conceal the fastener, the capping member comprising an engagement part for engaging a portion of at least one of the cladding panels to retain the capping member in the mounted position.

[0016] The present invention may advantageously enable a secure mounting of cladding panels to the support member via a fastener whilst simultaneously allowing for a ‘screwless’ appearance via use of the capping member which is configured to visually conceal the fastener.

[0017] In a particular embodiment, the engagement between the capping member engagement part and the cladding panel permits retention of the capping member without use of a fastener. The capping member may be connected via a screwless mounting. For example, the capping member may be mountable via an engagement part which engages with a portion of the cladding panel. The system may advantageously allow for the panels to be secured via a reliable fastener mounting whereas the capping member that is less prone to wind-induced disconnection may be mounted using a screwless connection and thereby providing a desirable screwless visual appearance.

[0018] It will be appreciated that the use of a fastener to mount the cladding panels to the support member provides a significantly stronger connection as compared to a ‘snap-fit’ panel engagement which, as discussed in the foregoing, can be limited by the manual force that an installer can reasonably be expected to apply in a repetitive manner. In this regard, the security of the connection between the cladding panel and support member is not compromised to achieve a screwless appearance. 2026201962   16 Mar 2026

[0019] The present invention may allow for the connection strength between the cladding panels and support member to be determined by the pull-out force of the fastener which will be understood to a person skilled in the art and be selected (via selections such as fastener size, cladding panel material and thickness) to achieve a desired wind-resistance for a particular application.

[0020] Furthermore, in contrast to some existing cladding systems, the present invention does not require a snap-lock engagement between adjacent panels to resist forces from wind loading. This may reduce the installation force required of the installer and which may improve installation health safety, speed and efficiency. In a particular embodiment, the capping member is configured to require a sufficiently low installation force such that it does not deform the panels during its installation and especially at mid-span between brackets.

[0021] In particular embodiments, the support member is mountable to the building via a fastener. The support member may comprise one or more fastener openings permitting fastening of the support member to a building such as steel frame members, battens, joists, purlins or other building structural members. The support member may be configured for mounting to a building frame member. In a particular embodiment, the system includes a plurality of support members. In a particular embodiment, the first and second cladding panels are mountable to a first support member located at or adjacent a first end of the first and second cladding panels, and are mountable to a second support member located at or adjacent a second end of the first and second cladding panels. The support member may comprise a longitudinal axis which, in use, is orientated perpendicularly to a longitudinal axis of the cladding panels.

[0022] In a particular embodiment, the capping member is configured to engage with the at least one cladding panel via a resilient engagement. For example, the resilient engagement may comprise a snap-lock engagement. The snap-lock engagement may comprise a flexibly resilient portion which resiliently deforms away from a normal position while a force is applied to capping member is pressed by an installer. Once a predetermined position is reached, the flexibly resilient portion may ‘snap’ into engagement with the cladding panels to secure the capping member. In the locked position (i.e. the mounted position of the capping member), the flexible portion may have returned to its ‘normal’ or ‘rest’ position. Alternatively, in the 2026201962   16 Mar 2026 mounted position the flexibly resilient portion may have moved closer to its normal position but is still flexibly deflected such that it continues to urge towards its normal position whilst in the mounted position.

[0023] According to a particular embodiment, the capping member remains deflected from a normal position when in its mounted position. The capping member may therefore apply a force on the underlying side portions when in its mounted position. In a particular embodiment, the capping member in its mounted position applies force on both the first and second side portions in a direction toward the support member.

[0024] In a particular embodiment, the flexibly resilient portion of the capping member is a flexible arm and the engagement part of the capping member is located on, or forms part of, said arm.

[0025] In a particular embodiment, the cladding panel side portions each comprise a mounting formation configured for resilient engagement with the capping member engagement part and permitting mounting of the capping member. In a particular embodiment, the engagement portion of the capping member and the mounting formations of the side portions have a corresponding configuration. For example, these parts may correspond in shape and / or size and / or position so as to facilitate engagement when the capping member is located in the mounted position.

[0026] The capping member may comprise a pair of first and second engagement parts. In the mounted position, the first engagement part may be engaged with a mounting formation on the first cladding panel and the second engagement part is engaged with a mounting formation on the second cladding panel. In this manner, a single capping member may engage with side portions of two different cladding panels.

[0027] In a particular embodiment, the engagement parts of the capping member are resiliently urged toward engagement with the mounting formations of the side portions. In a particular embodiment, the resiliency of the capping member may operate to compress or urge the side portions toward the support member. In a particular embodiment, the resiliency of the capping member may operate to resist or prevent movement of the side portions away from the support member. 2026201962   16 Mar 2026

[0028] In a particular embodiment, the capping member comprises a pair of first and second engagement parts and wherein, in the mounted position, the first engagement part is resiliently urged toward engagement with a mounting formation of the first cladding panel and the second engagement part is resiliently urged toward engagement with a mounting formation of the second cladding panel.

[0029] In a particular embodiment, the side portions of the first and second cladding panels are mountable in a non-overlapping configuration. The side portions may be configured for mounting in a side-by-side configuration. The side portions may be configured for mounting in an abutting configuration. For example, with edges of each side portion in abutment.

[0030] Alternatively, in a particular embodiment the first and second side portions are mountable to the support member in an overlapping arrangement wherein one of the side portions overlaps the other side portion. For example, the side portions may be mountable with the first side portion overlapping the second side portion. In a particular embodiment, the first side portion of the first cladding panel overlaps an end surface of the support member, and the second side portion of the second cladding panel overlaps the first side portion of the first cladding panel.

[0031] In a particular embodiment, the capping member comprises a pair of first and second resilient arm portions, the first engagement part extending from the first resilient arm portion and the second engagement part extending from the second resilient arm portion.

[0032] The capping member may further comprise a covering portion configured to cover and conceal a head of the fastener. The covering portion could be configured in a variety of ways. The covering portion could be a portion of the resilient arm portions. The resilient arm portions could be connected to one another or, alternatively, could be spaced from one another by the covering portion. In a particular embodiment, the capping member may have U-shaped configuration wherein opposite ends of the U-shape provide the resilient arm portions and a central part of the U-shape provides the covering portion.

[0033] Alternatively, the covering portion could be separate to the resilient arm portions and, for example, could be located between the resilient arm portions. The resilient arm portions might extend from opposite sides of the covering portion. In a particular embodiment, 2026201962   16 Mar 2026 the capping member comprises a flat or planar portion such as a flat-top. Alternatively, the capping member may have a continuously curved configuration. The resilient arm portions may be angled with respect to the covering portion.

[0034] In a particular embodiment, the engagement parts extending inwardly from the resilient arm portions and generally toward a central axis of the capping member. The engagement parts may extend inwardly and generally toward a plane of symmetry of the capping member.

[0035] In a particular embodiment, the arm portions defining a space therebetween for receiving at least part of the side portions and at least part of the support member. In a particular embodiment, the arm portions extend outwardly from opposite sides of the covering portion and define a trapezoidal-shaped receptacle bounded on two sides by the arm portions and on an upper side by the covering portion.

[0036] The resilient arm portions of the capping member may permit resilient movement of the engagement parts relative to the covering portion to permit a snap-lock engagement between the capping member and the cladding panel mounting formations.

[0037] In a particular embodiment, the capping member comprises a pair of first and second resilient arm portions, wherein in the mounted position of the capping member, the first resilient arm portion forms a generally continuous exterior surface with the first cladding panel and the second resilient arm portions forms a generally continuous exterior surface with the second cladding panel.

[0038] In a particular embodiment, the capping member comprises a pair of first and second resilient arm portions wherein in the mounted position of the capping member, distal sections of the resilient arm portions are in approximately alignment with wall portions of the cladding panels adjacent to the side portion mounting formations.

[0039] In a particular embodiment, the cladding panel side portions each comprise a mounting formation configured for resilient engagement with the capping member, and the support member comprising one or more mounting formations shaped to engage with one or both of the mounting formations of the side portions. 2026201962   16 Mar 2026

[0040] In a particular embodiment, in the mounted position of the capping member, the first resilient arm portion forms a generally continuous exterior surface with the first cladding panel and the second resilient arm portions forms a generally continuous exterior surface with the second cladding panel. In the mounted position of the capping member, distal sections of the resilient arm portions may be in approximate alignment with wall portions of the cladding panels adjacent to the side portion mounting formations. In a particular embodiment, the capping member comprises a pair of resilient arm portions configured to flex apart from one another during installation over the mounted side portions until the engagement parts of the capping member reach the cladding panel mounting formations at which time the engagement parts snap into receipt with the mounting formations to snap-lock the capping member in the mounted position. Fitting the capping member may involve an installer locating the capping member loosely atop the mounted side portions (and after a fastener has been installed) and pressing the capping member toward the support member causing the resilient arms to initially flex outwardly from each other and sliding along the mounted side portions until the snap-lock is achieved.

[0041] It will be appreciated that cladding panel systems will typically include more than two cladding panels and more typically could include a row or series of numerous cladding panels. It will be appreciated that each intersection of two adjacent cladding panels in the series / row may comprise an overlapping arrangement which comprises a support member that is overlapped by the pair of overlapping side portions of the adjacent cladding panels and a capping member which covers and conceals the overlap of the side portions. In this overlapping configuration, the side portions may overlap the end surface of the support member.

[0042] The side portions may be positioned relative to each other in an overlapping or non-overlapping configuration. For example, the side portions may be in a non-overlapping configuration in which each side portion overlaps and contacts a different part of the support member. Alternatively, the side portions could overlap each other. For example, the side portion of the first panel could overlap and contact an end surface of the support member and 2026201962   16 Mar 2026 the side portion of the second panel could overlap the first panel side portion but without contacting the support member end surface.

[0043] In certain embodiments, each capping member is associated with one support member and with two overlapping cladding panels. The capping member may be shaped commensurately with a shape or profile of the support member. In a particular embodiment, the capping member defines an interior space, volume or cavity that is approximately matched or corresponds with a profile of the support member.

[0044] In a particular embodiment, the panel side portions are located between the capping member and the support member and wherein the capping member does not contact the support member. In a particular embodiment, the support member is substantially covered by the panel side portions.

[0045] In a particular embodiment, the capping member comprises a pair of resilient arms defining a space or receptacle for receiving at least part of the overlapping arrangement. The capping member receptacle may be configured to receive or cover at least part of the support member.

[0046] In a particular embodiment, the capping member comprises a covering portion for covering and concealing the fastener. It will be appreciated that part of the fastener may be embedded in the overlapping arrangement and, for example, may extend through the overlapping side portions of the cladding panels and into the support member. The covering portion may therefore be configured for covering only part of the fastener. The covering member may be configured for covering a head of the fastener. For example, the covering member may cover and conceal a screw head.

[0047] In a particular embodiment, the covering portion and planar parts of each side portion are parallel. The end surface and side portion planar parts may be in an overlapping configuration which results in a layered configuration. The covering portion of the capping member may be spaced from the layered configuration by at least the height of a fastener head which extends through the layered configuration to secure the side portions to the support surface of the support member. 2026201962   16 Mar 2026

[0048] In a particular embodiment, the pair of resilient arms of the capping member extend from the covering portion. The pair of resilient arms may extend from opposite sides of the capping member. In a particular embodiment, the pair of arms and the covering portion may collectively define the space or receptacle for receiving the overlapping arrangement and which may also include a portion of the support member.

[0049] In a particular embodiment, the engagement part of the capping member comprises a first engagement part located on a first of the pair of arms and the capping member further comprises a second engagement part located on a second of the pair of arms. In a particular embodiment, the capping member may permit resilient movement of the engagement parts relative to the covering portion and wherein the capping member is configured for mounting to the cladding panels via a snap-lock engagement.

[0050] The capping member, support member and cladding side portions may be correspondingly shaped or otherwise configured to achieve a desired visual appearance or aesthetic effect. The cladding panel side portions, support member and capping member may be configured for a synergistic visual appearance. For example, an exterior surface of the assembled system may comprise a transition from the cladding panel to the capping member and said transition may be configured to be visually discrete.

[0051] In a particular embodiment, the capping member has an exterior surface which, in the mounted position of the capping member, forms one or more generally continuous surfaces with one or more exterior surfaces of the cladding panels. In a particular embodiment, the capping member and cladding panels may be configured to form a generally continuous exterior surface. In a particular embodiment, a first of the cladding member arms may be configured to form a generally continuous exterior surface with the first cladding panel and a second of the cladding member arms may be configured to form a generally continuous exterior surface with the second cladding panel.

[0052] The generally continuous exterior surface may comprise a transition between the cladding panels and the arms. However, the transition may be configured to minimise visual interruption with the otherwise continuous exterior surface. For example, in the mounted position of the capping member, the resilient arms are orientated in approximate alignment with wall portions of the cladding panels. Said wall portions may be portions of the cladding 2026201962   16 Mar 2026 panel at or adjacent the transition. The arms of the capping member may be configured such that they are aligned with the wall portions at the transition to achieve a relatively continuous visual appearance. In a particular embodiment, the arms of the capping member and the wall portions of the cladding panels have a relative angle at or near to 0 degrees at the transition.

[0053] In a particular embodiment, the transition between the capping member and the cladding panels is at or adjacent the location of the engagement parts of the capping member and / or the mounting formations of the cladding panels. Therefore, the wall portions of the cladding panels may be in approximately alignment with the capping member arms located at or adjacent the engagement parts of the capping member.

[0054] It will be appreciated that the engagement parts and the mounting formations could be configured in a variety of ways. In a particular embodiment, the mounting formations of the side portions comprise indents or notches and the engagement parts of the capping member are shaped for commensurate receipt with the indents or notches. The indents or notches have a generally triangular profile.

[0055] The engagement parts of the capping member may comprise flanges angled with respect to an axis of the resilient arms and configured for engagement (for example, abutment) with wall portions of the indents or notches. In a particular embodiment, each flange of the capping member extends from one of the resilient arms at an acute angle relative to that resilient arm. In a particular embodiment, the flanges of the capping member extend inwardly and generally toward a plane of symmetry of the capping member.

[0056] In a particular embodiment, the engagement part(s) of the capping member could comprise a part which is connected to the capping member. For example, a flange or protrusion or rib or bracket which is attached (removably or non-removably) to the capping member. Alternatively, the engagement parts could be an integrally formed part of the capping member. In a particular embodiment, the engagement parts of the capping member are engagement formations. The engagement formations may be integrally formed parts of the resilient arms. The engagement formations may comprise folded portions. The engagement formations may comprise folded flanges located at distal ends of the resilient arms of the capping member. 2026201962   16 Mar 2026

[0057] It will be appreciated from the foregoing that the cladding panels and the capping member may have corresponding engagement / mounting formations designed to resiliently secure the capping member to the cladding panels without need for fasteners. In a further embodiment, the support member may also be provided with a mounting formation configured (for example, shaped) to engage with one or both mounting formations of the side portions. The mounting formations of the support member may engage with the mounting formations of the cladding panels to supplement the mounting engagement provided by the fastener. The support member mounting formations may also assist in locating the cladding panels in the overlapping arrangement with the support member during the installation procedure.

[0058] The mounting formations of the support member may also correspond with the engagement parts of the capping member. In this manner, the capping member, the overlapping cladding panels and the support member may each have corresponding formations which enhance aesthetics and / or mounting strength of the system. For example, the support member mounting formations may comprise a recess, indent, notch or other inward depression in which the cladding panel mounting formation and the capping member engagement part is received.

[0059] Said receipt of the capping member engagement part and the side portion mounting formation may facilitate concealment of these formations and thereby improving system aesthetics. In a particular embodiment, the capping member engagement part, the cladding panel mounting formation and the support member mounting formation are concealed behind part of the cladding panel and / or the capping member, when the capping member is in the mounted position.

[0060] In a particular embodiment, the capping member in its mounted position may operate to retain the cladding panel mounting formations within the mounting formations of the support member. In a particular embodiment, the capping member in its mounted position may urge the cladding panel mounting formations toward the mounting formations of the support member.

[0061] In a particular embodiment, the support member mounting formation comprises a generally triangular indent. In a particular embodiment, the cladding panel mounting 2026201962   16 Mar 2026 formations comprise generally triangular formations of corresponding configuration and receivable within the indents of the support member. In a particular embodiment, the capping member engagement part(s) comprise angled flanges received within the mounting formations of the cladding panel whilst they are received within the indents of the support member. In a particular embodiment, the capping member engagement parts and the cladding panel mounting formations and the support member mounting formations have a nested configuration.

[0062] In a particular embodiment, the support member mounting formation comprises an indent and the side portion mounting formation is configured to locate in the support member indent and the capping member engagement part is configured to locate in the side portion mounting formation whilst the side portion mounting formation is located in the support member indent. Said engagement between the cladding panel mounting formations and the engagement may thereby permit mounting of the capping member.

[0063] In a particular embodiment, the at least one fastener extends through the first side portion of the first cladding panel and the second side portion of the second cladding panel.

[0064] In a particular embodiment, the first and second side portions are mountable to the support member in an overlapping arrangement wherein the first side portion of the first cladding panel overlaps the support member, and the second side portion of the second cladding panel overlaps the first side portion of the first cladding panel and wherein the at least one fastener extends through each side portion in the overlapping arrangement.

[0065] The cladding panel side portions advantageously have profiles complementary to a profile of the support member. For example, the side portions may be shaped to fit against, over or with the support member. In a particular embodiment, the cladding panel side portions are shaped to correspond with a profile of the support member. The side portions may be shaped to match or otherwise correspond with a profile or outer surface of the support member. The side portions and support member profile may have complementary configurations such as complementary shapes or formations. For example, the side portions may be shaped for complementary engagement with the profile of the support member. The side portions may be shaped for complementary overlap with the support member. The cladding panel side portions may be shaped for seating on part of the support member. The 2026201962   16 Mar 2026 cladding panel side portions may be configured to cooperatively seat and engage with a portion of a surface of the support member. In a particular embodiment the support member comprises a base and an upstanding portion extending from the base. The upstanding portion may have a generally trapezoidal profile. The upstanding portion may taper or otherwise narrow from the base toward the end surface. The support member may have a truncated triangular profile which tapers toward the end surface.

[0066] The cladding panel side portions may have profiles complementary to the support member profile and, for example may be similarly shaped and may comprise a trapezoidal or truncated triangular profile. This may permit seating of a side portion on the support member. In particular, seating of the correspondingly shaped side portion on the support member may facilitate installation of the system insofar as the cladding panels can seat in the intended position prior to fastening. In a particular embodiment, the support member, the cladding panel side portions and the capping member each define a generally trapezoidal profile (i.e. when viewed in cross-section and along a longitudinal axis of these components).

[0067] In a particular embodiment, the capping member has a symmetrical profile. In an embodiment, the cladding panels may have a symmetrical profile. In an embodiment, the cladding panels have a concave profile which extends between the opposite side portions.

[0068] In an embodiment, the capping member and the first and second cladding panels collectively define a truncated peak profile. For example, wall portions of the first and second cladding panels may collectively define a curved base of the peak profile and which transitions into a trapezoidal tip defined by the capping member.

[0069] According to another aspect of the invention, there is provided a building cladding system comprising: at least one support member secured to a building; first and second cladding panels each having side portions secured to the support member via one or more fasteners and the side portions having profiles complementary to a profile of the support member; a capping member resiliently engaged with mounting formations on the cladding panels to mount the capping member in a mounted position wherein the capping member covers and visually conceals the fastener. In a particular embodiment, the side portions are arranged to form a lapping arrangement which overlies the support member. 2026201962   16 Mar 2026

[0070] According to a further aspect of the invention, there is provided a method of cladding a building comprising: mounting at least one support member to a structural portion of the building; providing a pair of first and second cladding panels each having a pair of opposite side portions with profiles complementary to a profile of the support member and each side portion configured with a mounting formation; mounting the side portions to the support member using one or more fasteners; mounting a capping member over the mounted side portions to conceal the one or more fasteners, the capping member configured for snaplock engagement with the mounting formations of the panel side portions.

[0071] In a particular embodiment of this method, the step of mounting the side portions comprises the steps of: locating a side portion of the first cladding panel on the support member; locating a side portion of the second cladding panel on the side portion of the first cladding panel so that the side portion of the second cladding panel overlaps the side portion of the first cladding panel; securing the overlapping side portions using a fastener which extends through each of the overlapping side portions.

[0072] In a particular embodiment of the above-noted method, the capping member is fitted via a resilient snap-lock engagement between the capping member and the cladding panels.

[0073] The capping member may comprise an exterior surface configured for visual continuity with exterior surfaces of the cladding panels. In a particular embodiment, the capping member, support member and the cladding panels are configured to facilitate visual continuity along an exterior surface collectively formed by the capping member and the cladding panels.

[0074] The capping member may comprise a pair of resilient arm portions defining a space therebetween for receiving the mounted side portions and also receiving a portion of the support member and wherein mounting of the capping member comprises resiliently deforming the arm portions in a direction away from each other such that the arms experience a resilient urge in a direction towards each other.

[0075] In a particular embodiment, the pair of arm portions comprises a first arm having a first engagement part and a second arm having a second engagement part and each of the 2026201962   16 Mar 2026 first and second cladding panels provided with an indent configured to receive one of the engagement parts, wherein mounting of the capping member comprises locating the first engagement part in the indent of the first cladding panel and locating the second engagement part in the indent of the second cladding panel.

[0076] In a further embodiment of the above-discussed method, the support member has one or more mounting formations and wherein one or both of the side portion mounting formations are engaged with the one or more mounting formations of the support member.

[0077] In typical embodiments, the cladding panel system of the present invention may comprise a plurality of support members in order to affix a series of cladding panels to a building. Accordingly, in particular embodiments, both first and second side portions of a cladding panel will be fastened to a support member. For example, a first side portion of a first cladding panel may be fastened to a first support member as the underlapping side portion and the second side portion of the first cladding panel may be fastened to a second support member as the overlapping side panel. It will be appreciated that cladding panels fastened at both sides to a support member provide improved wind-resistance as compared to some existing ‘snap-lock’ panel systems which avoid the use of fasteners in pursuit of improved aesthetics but at the detriment of panel connection strength.

[0078] In particular embodiments, the cladding panels comprise sheet steel material. The cladding panels may comprise any other suitable material such as composite material or polymer material. Similarly the capping member and support member may be formed from metallic material such as steel, or from polymer material such as plastic, or from any other suitable material. The cladding panels and capping member may typically be manufactured by a combination of a rolling machine and folding, or by roll-forming. Other manufacturing methods may be utilised as appropriate for the application and for the material being used.

[0079] In a particular embodiment, the support member may be manufactured by laser cutting or by punching and folding or, alternatively, using a die press to press and form the support member into the desired form or shape.

[0080] In a particular embodiment, the system comprises a plurality of the support members mountable to the building in an overlapping configuration. As noted in the foregoing, 2026201962   16 Mar 2026 each support member may comprise a base and an upstanding portion extending from the base. The overlapping configuration of the support members may comprise overlapping the bases of adjacent support members. In a particular embodiment, the base of each support member includes fastener openings for receiving a fastener to mount the base to the building. In the overlapping configuration, the base of a first support member may be overlapped by the base of a second support member mounted adjacent to the first support member and wherein fastener openings of each first and second support member are aligned to receive a single fastener therethrough.

[0081] In a particular embodiment, the base of each support member comprises a fastener opening at or adjacent opposite ends of the base. The ends of the support member bases may be overlapped with fastener openings aligned and such that a single fastener can mount the ends of adjacent support members. In a particular embodiment, the support member base is provided with three fastener openings comprising a first end opening at or adjacent a first end of the base, a second end opening at or adjacent a second end of the base and a third opening at or adjacent the upstanding portion of the support member. In a particular embodiment, the first opening and the third opening are proximate the upstanding portion of the support member. Brief Description of Drawings

[0098] Figures 1 and 2 illustrate a building cladding system 10 mounted to a building. In particular, the system is mounted to horizontal frame members 12 that are connected to vertical members 14. Figure 1 illustrates an assembled view whereas Figure 2 illustrates an exploded view to assist with component description.

[0099] The system 10 comprises a plurality of support members comprising brackets 16 mounted to horizontal members 12. The system 10 further comprises a plurality of cladding panels 18 mounted to the brackets 16.

[0100] Figures 1 and 2 illustrate three of the cladding panels 18 which comprise a first panel 18-1, a second panel 18-2 and a third panel 18-3. It will be appreciated that the system 10 may comprise as little as two cladding panels 18 and could comprise as many panels 18 as 2026201962   16 Mar 2026 required to cover a particular portion of the building. As shown in Figure 2, each cladding panel 18 comprises a first side portion 18a and an opposite second side portion 18b. The cladding panels 18 are mounted in an overlapping arrangement whereby at least one side portion of each cladding panel either overlaps or underlaps the side portion of an adjacent panel 18. The overlapping arrangement will be discussed subsequently in further detail.

[0101] The system 10 further comprises fasteners which extend through overlapping side portions of the panels 18 for securing the side portions to the brackets 16. The system further comprises capping members 20 which are mountable over the overlapping side portions in order to cover and conceal the fasteners and provide the system 10 with a ‘screwless’ visual appearance. Figure 1 illustrates a first capping member 20-1 covering overlapping side portions of the first panel 18-1 and second panel 18-2 and a second capping member 20-2 covering overlapping side portions of the second panel 18-2 and the third panel 18-3.

[0102] The system 10 may comprise identical brackets 16, identical panels 18 and identical capping members 20. In this manner, a consumer or installer may purchase the appropriate number of these three components to clad a desired area.

[0103] Turning to Figures 3 and 4, features of the cladding panels 18 will be discussed in further detail with Figure 3 providing a side-view of a panel 18 and Figure 4 providing a perspective view.

[0104] Each cladding panel 18 comprises a concave profile 19 which extends between the opposite side portions 18a, 18b. The panel 18 further comprises a pair of opposite ends 21. The panel 18 is symmetrical about a central plane CPCLAD. The first and second side portions 18a, 18b are therefore mirror images of one another. The panel 18 has a one-piece configuration. The profile of the panel side portions 18a, 18b features a seating formation comprising trapezoidal portion 22 configured for seating on a portion of the bracket 16.

[0105] The side panel profile further comprises a mounting formation 24 of triangular profile. As shown in Figure 4, the first side portion 18a comprises a first trapezoidal portion 22a and a first mounting formation 24b. The second side portion 18b comprises a second trapezoidal portion 22b and a second mounting formation 24b. 2026201962   16 Mar 2026

[0106] The cladding panels 18 may typically have an elongated profile with a length measured along a longitudinal axis AL that is greater than a width measured between the opposite side portions 18a, 18b. It will be appreciated that the exact dimensions such as the length and width of the panel 18 may vary.

[0107] Turning to Figures 5 and 6, the features of the capping member 20 will be discussed in further detail with Figure 5 providing a perspective view and Figure 6 providing a side view.

[0108] The capping member 20 has a one-piece configuration. The capping member 20 comprises a planar covering portion 26 and a pair of resilient arm portions comprising arms 28 extending from opposite longitudinal sides of the covering portion 26. The capping member 20 is symmetrical about a central plane CPCAP.

[0109] The capping member 20 is provided with a pair of engagement parts comprising flanges 30 located at distal ends of the resilient arms 28. The flanges 30 are folded inwardly from the resilient arms such that flanges 30 extend from the resilient arms generally toward the central plane CPCAP. The resilient arms extend from the covering portion 26 generally away from the central plane CPCAP.

[0110] As shown in Figure 6, the flanges 30 comprise a first flange 30a located on a first of the resilient arms 28a and a second flange 30b located on a second of the resilient arms 28b. The flanges 30 are angled from their respective arm 28 at an acute angle a. In a particular embodiment, the angle a may be in the range of 50 to 60 degrees. In a particular embodiment, the angle a may be approximately 55 degrees. As will be discussed subsequently in further detail, the capping member flanges 30 are configured for engagement with cladding panel mounting formations 24.

[0111] As illustrated in Figure 6, capping member 20 comprises an interior space bounded on three sides by the covering portion 26 and the pair of resilient arms 28. The interior space comprises a receptacle 32 configured for receiving at least part of an overlapping arrangement of cladding panel side portions, which will be discussed subsequently in further detail.

[0112] The resilient arms 28 of capping member 20 are configured for resilient movement toward and away from one another as indicated by arrows RM in Figure 6. The resilient 2026201962   16 Mar 2026 movement of arms 28 permits resilient movement of the flanges 30 toward or away from the central plane CPCAP.

[0113] Turning to Figures 7 to 9, the features of the bracket 16 will be discussed in further detail with Figure 7 providing a side view, Figure 8 providing a perspective view and Figure 9 providing an underside view of the bracket 16.

[0114] The bracket 16 comprises a base 34 and an upstanding portion 36 located toward a first end 34a of the base 34. The base 34 comprises a second end 34b. As labelled in Figures 8 and 9, the second end 34b of the base 34 is provided with a trapezoidal protrusion 40. As best shown in Figure 8, the first end 34a of the base 34 is provided with a trapezoidal recess 42 of corresponding configuration to the trapezoidal protrusion 40.

[0115] As shown in Figure 8, the base 34 comprises several fastener openings comprising a first opening 38 located at the recess 42 at the first end 34a, and second opening 39 located at the protrusion 40 at the second end 34b. The base 34 further comprises an intermediate opening 43 located in the base 34 intermediate of the first opening 38 and the second opening 39.

[0116] The corresponding protrusion 40 and recess 42 facilitate the mounting of a series of successive brackets 16 wherein the second end 34b of a first bracket 16 is overlapped by the first end 34a of an adjacent second bracket 16. The protrusion 40 of the first bracket 16 is received in the recess 42 of the second bracket 16 to facilitate a seated overlap. The seated overlap facilitates location of adjacent brackets 16 in a desired relative position. In particular, with the recess 42 of the second bracket 16 seated upon the protrusion 40 of the first bracket, the upstanding portions 36 of the first and second bracket are located in a desired spacing that is associated with a width of the cladding panel 18.

[0117] With first and second adjacent brackets 16 in the seated overlap position, the second opening 39 of the first bracket 16 is aligned with the first opening 38 of the second bracket 16. A single fastener may then be used through the aligned openings 38, 39 to mount the adjacent brackets 16 to the building.

[0118] This configuration is best illustrated in Figure 13, which illustrates a row of four adjacent brackets 16 comprising a first bracket 16-1, second bracket 16-2, third bracket 16-3 2026201962   16 Mar 2026 and fourth bracket 16-4. The row of brackets 16 are arranged in seated overlap whereby the trapezoidal protrusion 40 of the first bracket 16-1 is overlapped and received in the recess 42 of the second bracket 16-2. The protrusion 40 of the second bracket 16-2 is overlapped and received in the recess 42 of the third bracket 16-3. The protrusion 40 of the third bracket 16-3 is overlapped and received in the recess 42 of the fourth bracket 16-4.

[0119] Still referring to Figure 13, first fasteners 44 are inserted through the overlapped ends of the row of brackets 16 and, in particular, through the aligned first and second openings 38, 39. The mounting of brackets 16 to the building further comprises second fasteners 46 inserted through the intermediate openings 43. Each bracket 16 is therefore secured to the building via three fasteners.

[0120] Returning to Figures 7 to 9, the upstanding portion 36 of the bracket 16 comprises a generally trapezoidal profile having a pair of opposite upright walls 48 orientated perpendicularly with the base 34 and a pair of opposite inclined walls 50 which are inclined relative to the base 34. The upstanding portion 36 further comprises a planar end surface 52 spaced from the base 34 by a height of the upstanding portion 36. The end surface 52 is orientated parallel with the base 34. The end surface 52 may therefore be orientated parallel with a surface of a building on which the base 34 is mounted. The end surface 52 has rectangular perimeter bounded by upper edges of the upright walls 48 and inclined walls 50.

[0121] As best shown in Figure 7, the end surface 52 and inclined walls 50 collectively form a generally trapezoidal upper part 66 of the upstanding portion 36. The trapezoidal profile of the bracket 16 corresponds with the trapezoidal portion 22 of the panels 18. As will be discussed subsequently in further detail, the end surface 52 (and the trapezoidal part 66) of the bracket 16 is thereby configured as a seat for the side portions 18a, 18b of the panels 18.

[0122] Referring to Figures 7 and 8, the bracket 16 has a pair of mounting formations 54 formed in the inclined walls 50 and which comprise triangular indents. As will be discussed subsequently in further detail, the mounting formations 54 of the bracket 16 are configured to engage with the triangular mounting formations 24 of the cladding panels 18, and also with the flanges 30 of the capping member 20. 2026201962   16 Mar 2026

[0123] Referring to Figure 8, the end surface 52 of the brackets 16 is formed from a folded sheet portion and extends between a first fold 56 and a second fold 58. The first fold defines an edge between a first of the inclined walls 50 and the end surface 52. Referring to Figure 10 which illustrates a front view of the bracket 16, the second fold 58 defines an edge between the end surface 52 and a flap 60 folded into a notch 62 in a second of the inclined walls 50. The flap 60 comprises a pair of opposite tabs 64 which extend beyond opposite ends of the notch 62 to project beyond the opposite upright walls 48. The tabs 64 may form an interlock with the notch 62 which may advantageously increase strength of the end surface 52. The interlock between the tabs 64 and notch 62 may help ensure the end surface 52 does not deform when subject to force from wind load applied to the cladding panels 18.

[0124] Turning to Figures 11 and 12, four of the brackets 16, three of the cladding panels 18, and two of the capping members 20 are assembled with corresponding trapezoidal formations of the various components arranged in an overlapping arrangement. For ease of illustration, the cladding panels 18 and capping members 20 are shown with generally shorter length than would be typically used in system 10. Also, for ease of illustration, Figures 11 and 12 are shown without fasteners.

[0125] A first side portion 18a of a first cladding panel 18-1 seated upon a first bracket 16 1 with the trapezoidal portion 22 of the first panel 18-1 seated upon the trapezoidal upper part 66 of the first bracket 16-1. The second side portion 18b of the first cladding panel 18-1 is seated on the upper part 66 of the second bracket 16-2.

[0126] A first side portion 18a of the second cladding panel 18-2 overlaps and seats upon the second side portion 18b of the first cladding panel 18-1. In this manner, the second bracket 16-2, second side portion 18b of the first panel 18-1 and first side portion 18a of the second panel 18-2 are overlapped to form an overlapping arrangement. The first capping member 201 is then mounted in a position overlying the overlapping arrangement. The second side portion 18b of the second cladding panel 18-2 is seated upon the upper part 66 of the third bracket 16-3.

[0127] A first side portion 18a of the third cladding panel 18-3 overlaps and is seated upon the second side portion 18b of the second cladding panel 18-2. In this manner, the third bracket 16-3, the second side portion 18b of the second panel 18-2 and the first side portion 2026201962   16 Mar 2026 18a of the third panel 18-3 are arranged in an overlapping arrangement. The second capping member 20-2 is then mounted in a position overlying this overlapping arrangement. The second side portion 18b of the third panel 18-3 is seated upon the upper part 66 of the fourth bracket 16-4.

[0128] The first and second capping members 20-1, 20-2 are mounted to the cladding panels 18 via a snap-lock engagement. In particular, the flanges 30 of the capping members 20 engage with the mounting formations 24 in the cladding panels. In Figure 12, the first capping member 20-1 is mounted over the second bracket 16-2 and over the overlapping side portions of the first panel 18-1 and second panel 18-2. The second capping member 20-2 is mounted over the third bracket 16-3 and over the overlapping side portions of the second panel 18-2 and third panel 18-3. The first and fourth brackets 16-1, 16-4 are shown without associated capping members 20 and the mounting formation 24 of the second side portion 18b of the third panel 18-3 is visible for comparative purposes.

[0129] Turning to Figures 13 and 14, side views of the exploded and assembled views shown in Figures 11 and 12 are provided but with fasteners also shown.

[0130] As discussed in the foregoing, the first fasteners 44 and second fasteners 46 are used for mounting the brackets 16 to a building structure such as frame members of a building. The first fasteners 44 are typically inserted through aligned fastener openings in overlapping parts of the bracket bases 34. An exception is the first fastener 44 in the first bracket 16-1 which being first in the row of brackets 16 does not overlap an adjacent bracket base 34. The second fasteners 46 are inserted through the intermediate openings 43 shown in Figure 9.

[0131] Figures 13 and 14 show an additional fastener comprising panel fasteners 68 which secure the panels 18 to the brackets 16. In particular, Figure 13 illustrates three panel fasteners 68 comprising a first panel fastener 68-1 associated with the first bracket 16-1, a second panel fastener 68-2 associated with the second bracket 16-2 and a third panel fastener 68-3 associated with the third bracket 16-3. For ease of illustration a panel fastener associated with fourth bracket 16-4 is not shown in Figures 13 and 14 though it will be appreciated that in user a panel fastener will be used with each bracket 16. 2026201962   16 Mar 2026

[0132] The first panel fastener 68-1 extends through (and secures) the first side portion 18a of the first cladding panel 18-1 to the first bracket 16-1. The first side portion 18a of the first panel 18-1 is an outermost side portion in the row of panels and is therefore not overlapped by any other panel. The second panel fastener 68-1 extends through the first side portion 18a of the second panel 18-2 and through the second side portion 18b of the first panel 18-1 and into the second bracket 16-2 to secure this pair of side portions to the second bracket 16-2. The third panel fastener 68-3 extends through the first side portion 18a of the third panel 18-3 and through the second side portion 18b of the second panel 18-2 and into the third bracket 16-3 to secure this pair of side portions to the third bracket 16-3.

[0133] It will be appreciated that the second and third panel fasteners 68-2, 68-3 each secure a pair of overlapping side portions to a single bracket 16. It will also be appreciated that each panel 18 is fastened to a bracket 16 at both side portions of the panel 18. Referring briefly to Figure 1, it should also be appreciated that each panel will typically mounted on a bracket 16 at or near each of its opposite ends. Therefore, each side panel side portion 18a, 18b will typically be mounted to two brackets 16 at or near each of the opposite ends 21 (labelled in Figure 4). As such, in typical applications, a panel 18 may be secured to the brackets 16 via at least four panel fasteners 68. In applications where a panel 18 spans across several rows of the horizontal members 12 shown in Figure 1, a panel 18 may be mounted to each horizonal member 12 via a pair of brackets 16 and therefore each panel may be mounted using more than four brackets 16.

[0134] As shown in Figures 13 and 14, a capping member 20 is used to visually conceal the panel fasteners 68. For ease of illustration, only two capping members 20 are shown in Figures 13 and 14 though it will be appreciated that a capping member will typically be used to cover all panel fasteners 68 in order to provide the desired ‘screwless’ aesthetic.

[0135] The fasteners 44, 46, 68 may comprise screws. Alternatively, the fasteners may comprise other fasteners such as nails, bolts or rivets. It will be appreciated that the brackets 16 could be mounted to the building via connection or mounting systems other than via fasteners 44 and 48 shown in the illustrated embodiments. For example, the brackets could be mounted to a building using nails, clamps, adhesives or a combination thereof. 2026201962   16 Mar 2026

[0136] Turning to Figure 15, there is provided a closer view of the overlapping arrangement and of the concealment of panel fastener 68.

[0137] Figure 15 illustrates a bracket 16, a first side portion 18a of a first cladding panel 18-1, a second side portion 18b of a second cladding panel 18-2 and a capping member 20. As shown, the trapezoidal portion 22a of the first side portion 18a is seated upon (and overlaps) the trapezoidal upper part 66 of the bracket 16. The trapezoidal part 22b of the second side portion 18b is seated upon (and overlaps) the first side portion 18a to form an overlapping arrangement with the end surface 52.

[0138] Still referring to Figure 15, the triangular mounting formation 24-1 of the first cladding panel 18-1 is located within a first mounting formation 54a of the bracket 16. Similarly, the triangular mounting formation 24-2 of the second cladding panel 18-2 is located within a second mounting formation 54b of the bracket 16. During installation and prior to screwing the panel fastener 68, the engagement between the cladding panel mounting formations 24-1, 24-2 and the bracket mounting formations 54a, 54b may help to locate and hold the panels 18 in the correct position with minimal or reduced pressure from the installer and in some cases allowing the installer both hands free to fasten the panels 18 to the bracket 16.

[0139] A panel fastener 68 is screwed through the overlapping arrangement and into the end surface 52 of the bracket 16 to secure the side portions 18a, 18b to the bracket 16.

[0140] After fastening, the capping member 20 is then mounted to cover the overlapping arrangement via a snap-lock engagement wherein a first flange 30a of the capping member 20 is received within the first mounting formation 24-1 of the first cladding panel, and a second flange 30b of the capping member 20 is received within the second mounting formation 24-2 of the second cladding panel.

[0141] The resilient arms 28a, 28b of the capping member 20 are configured to flex apart from one another during installation over the overlapped side portions 18a, 18b until the engagement parts 30a, 30b of the capping member 20 reach the side portion mounting formations 24-1, 24-2 at which time the flanges 30a, 30b snap into receipt in the mounting formations 24-1, 24-2 to snap-lock the capping member 20 in the mounted position shown in 2026201962   16 Mar 2026 Figure 15. In this mounted position, the flanges 30a, 30b of the capping member 20 abut wall portions 55 of the mounting formations 24-1, 24-2.

[0142] Fitting the capping member may involve an installer locating the capping member 20 loosely atop the overlapped side portions 18a, 18b (and after the panel fastener 68 has been installed) and pressing the capping member 20 toward the bracket 16 causing the resilient arms 28a, 28b to initially flex outwardly from each other and sliding along the overlapped side 18a., 18b portions until the snap-lock is achieved.

[0143] As shown in Figure 15, the capping member 20 functions to conceal the panel fastener 68. In particular, the covering portion 26 of the capping member 20 overlies and conceals the head of panel fastener 68. Furthermore, the capping member 20 conceals the mounting formations 24-1, 24-2 of the side portions 18a, 18b. In this regard, the capping member creates a more continuous exterior surface for improved aesthetics. In the mounted position shown in Figure 15, the first resilient arm 28a forms a generally continuous surface with the first cladding panel 18-1 and the second resilient arm 28b forms a generally continuous surface with the second cladding panel 18-2.

[0144] The generally continuous exterior surface may comprise transitions 70a, 70b between the cladding panels 18-1, 18-2 and the arms 28a, 28b. The transitions 70a, 70b comprise a small notch which forms lines 72 along the base of the capping member that are labelled in Figure 1. The transitions 70a, 70b are configured for minimal visual interruption by orientating the arms 28a, 28b in approximate alignment with wall portions 74-1, 74-2 of the cladding panels adjacent to the transitions 70a, 70b. As shown in Figure 15, the arms 28a, 28b and the wall portions 74-1, 74-2 of the cladding panels 18-1, 18-2 form a relative angle of near to 0 degrees at the transitions 70a, 70b. This achieves a relatively continuous exterior surface of the system and minimises visual disruption at the transition between the panels 18 and capping member 20

[0145] It will be appreciated from Figure 15 that the capping member 20 and the cladding panels 18 collectively define a truncated peak profile wherein the cladding panels 18-1, 18-2 provide a curved base of the peak profile and which transitions into a trapezoidal tip defined by the capping member 20. 2026201962   16 Mar 2026

[0146] It will be appreciated from Figure 15 that as well as being configured in an overlapping arrangement, the bracket 16, and overlapping side portions 18a, 18b are also configured in a nested arrangement due to their corresponding trapezoidal profiles. In particular, the trapezoidal upper 66 of bracket 66 nests within the trapezoidal portion 22 of the first side portion 18a, which nests within the trapezoidal portion 22 of the second side portion 18b. The nested configuration may assist in locating the panels 18 in the correct position on the brackets 18 during installation. The nested configuration may also provide some additional mechanical strength in certain directions to supplement that of the panel fasteners 68.

[0147] Figure 16 illustrates an alternative embodiment of a building cladding system 100. The system 100 is a modification of the assembly shown in Figure 15 and in which the capping member 20 is generally unchanged from the previously illustrated system 10. System 100 differs from system 10 in that the cladding panels 118 are overlap on one of the inclined bracket walls 150 and a panel fastener 168 is screwed through the overlap into the inclined wall 150, as opposed to in Figure 15 where the panel fastener 58 screwed into the end surface 52. System 100 also differs from system 10 in that the bracket 116 has a narrower end surface 152 as compared to end surface 52 of bracket 16.

[0148] It will be appreciated from Figures 15-16 that the end surface 52, 152 may typically support a relatively high portion of panel load especially load in a downward direction (as viewed in Figures 15-16) toward the bracket 16, 116. However, it should be appreciated that end surface 52, 152 is not the only surface of the bracket 52, 152 which supports the panels 18, 118 and, for example, the inclined walls 50, 150 of the bracket 16, 116 also act to support the panels 18, 118.

[0149] As shown in Figure 16, the second side portion 118b of the second cladding panel 118-2 overlies the end surface 152 of the bracket 116. In particular, the second side portion 118b extends over and around the trapezoidal tip 176 of the bracket 116 and extends part way down the inclined wall 150. The first side portion 118a of the first cladding panel 118-1 extends part way up the inclined wall 150 and overlaps the second side portion 118b to form an overlapping arrangement between the side portions 118a, 118b and through which the panel fastener 168 is screwed to fasten the side portions 118a, 118b relative to the bracket 116. 2026201962   16 Mar 2026

[0150] Figure 17 illustrates another alternative embodiment of a building cladding system 200 and which differs from the systems 10, 100 of Figures 15 and 16 in that the first and second cladding panels 218-1, 218-2 are not overlapped on the bracket 216.

[0151] In contrast to systems 10, 100 the cladding panels 218-1, 218-2 of the system 200 are configured for mounting to the opposite inclined walls 250a, 250b and do not extend over the bracket end surface 252. In particular, the first side portion 218a of the first cladding panel 218-1 terminates at a first inclined bracket wall 250a and the second side portion 218b of the second cladding panel 218-2 terminates at a second inclined bracket wall 250b, but without any intersection, abutment or overlap between the two side portions 218a, 218b of the two panels 218-1, 218-2.

[0152] As shown, the first panel 218-1 is fastened to the first inclined wall 250a using a first panel fastener 268a and the second panel 218-2 is fastened to the second inclined wall 250b using a second panel fastener 268b. The capping member 20 illustrated in system 200 is of the same configuration as discussed in the foregoing with respect to system 10 and system 100.
