- the cladding system comprises a plurality of panels 2 , each secured to an underlying wall structure 3 so as to form an array 4 .
- Panels may be elongate and rectangular in shape; however, such a configuration is merely representative and non-limiting.
- Each array is often substantially rectangular; however, alternative configurations are acceptable and may be formed.
- Each array has substantially vertical side edges 5 . Where one array horizontally abuts another array, an optional joining strip 6 is provided, which is generally elongate (e.g., along the length of the array) and generally positioned vertically when arrays are so aligned. Further features of various forms of panel 2 and joining strip 6 are discussed below.
- Panel 2 has a first outer major face 7 and an opposing second inner major face 8 .

Description
- Any and all applications for which a foreign or domestic priority claim is identified in the Application Data Sheet as filed with the present application are hereby incorporated by reference under 37 CFR 1.57.
- 1. Field of the Invention
- The invention described relates generally to the field of building products and, more particularly, to building products having recessed joints.
- 2. Description of the Related Art
- Cement render applied over a thin panelised substrate may be used to provide one form of a masonry replica cladding system. Such systems usually require some form of mesh, fixed to a panel underlay, as a support and restraint for the render, use to provide the masonry appearance. These systems are relatively costly, time-consuming and, thus, inefficiently designed. For example, to install, such systems require specific skills and qualified persons to achieve a satisfactory appearance of the finished wall. Furthermore, the thickness of render applied in these systems does not generally allow for aesthetic finishes such as recessed joint lines without exposing the supporting mesh structure. Other systems that use thin ceramic tiles fixed to or hung on steel framing offer additional disadvantages. For example, tiles, which are inflexible, are unable to compensate for uneven framing. In addition, each tile system requires its own specific and special purpose framing to properly operate. An additional disadvantage includes the fact that working with individual tiles requires additional and labor-intensive handling operations. Other systems for large panel type cladding (e.g., similar to that used in commercial buildings) use plain panels mounted on special batten systems and, as such, remain unsuitable for replicating masonry and offer little aesthetic appeal.

The embodiments discussed herein are merely illustrative of ways to make and use the described invention and do not limit the scope of the invention.
- In the description which follows like parts may be marked throughout the specification and drawing with the same reference numerals, respectively. The drawing figures are not necessarily to scale and certain features may be shown exaggerated in scale or in somewhat generalized or schematic form in the interest of clarity and conciseness.
- Referring to
FIG. 1 , there is shown a perspective view of a wall structure using a representative cladding system 1 as described herein. The cladding system comprises a plurality ofpanels 2, each secured to anunderlying wall structure 3 so as to form anarray 4. Panels may be elongate and rectangular in shape; however, such a configuration is merely representative and non-limiting. Each array is often substantially rectangular; however, alternative configurations are acceptable and may be formed. Each array has substantiallyvertical side edges 5. Where one array horizontally abuts another array, anoptional joining strip 6 is provided, which is generally elongate (e.g., along the length of the array) and generally positioned vertically when arrays are so aligned. Further features of various forms ofpanel 2 and joiningstrip 6 are discussed below. - Turning to
FIG. 2 , there is shown arepresentative panel 2.Panel 2 has a first outermajor face 7 and an opposing second innermajor face 8. The panels are generally thin. The thickness may be less than 1 cm. In some forms, the thickness is less than 20 mm. In additional embodiments, the thickness is between about 14 and 16 mm Preferably, a panel terminates at opposingend 9 and end 10 (not shown). Each panel is also defined by a respective first and second major opposingedges first recess 13 is provided in the firstmajor face 7 of each panel adjacent the first major edge and is configured such that in use it resembles a recessed mortar joint.Recess 13 may be elongate in shape as shown inFIG. 2 or may form an alternative and suitable configuration. - One example of a panel dimension is that having a thickness of 14 mm and a width of
recess 13 of around 15 mm. A suitable length is often about 4.2 m lengths; however, it will be appreciated that this may vary, as may other dimensional parameters, to suit particular framing layouts, stud spacing arrangements and other design criteria, as desired. - In use, installation may include a first major edge of a first panel being positioned in an abutting relationship with a second major edge of an adjacent panel such that the abutment forms what resembles a recess mortar joint by taking advantage of the
first recess 13. Some form of sealing strip may also be applied along the butt joint, as desired. - Another panel embodiment is described with reference to
FIG. 3 in which like references are used to denote corresponding features. Dimensions of a panel ofFIG. 3 may be similar to that ofFIG. 2 . A difference between a panel ofFIG. 2 and that ofFIG. 3 resides in the edge of the panels. In this regard,first recess 13 formed infirst face 7 ofFIG. 3 is sized to have a width in excess of the width of the recessed mortar joint that in use is to be mimicked. In one example,first recess 13 ofFIG. 3 has a width of about 35 mm. In an embodiment, such as that disclosed withFIG. 3 , the depth ofrecess 13 is approximately 50% of the panel thickness. Other depths may be applied as desired. - Still referring to
FIG. 3 , asecond recess 14 is typically provided along the second major edge in the second major face. The configuration is such that when a plurality of panels are used to form an array 4 (as depicted inFIG. 1 ) for a wall cladding, the secondmajor edge 12 partially overlaps the recessed firstmajor edge 11 of an adjacent panel. The extended width of thefirst recess 13 may be small enough just to provide a useful degree of overlap of thesecond edge 12 of the adjacent panel, or may be wider so as to allow either blind nailing of the panel adjacent the first edge and/or simultaneous securing of that edge with an overlying second edge of a second panel by through-fixing at the overlap. A representative example includes having a width of asecond recess 14 at about 20 mm. With this dimension, when adjacent planks are aligned, approximately 15 mm ofrecess 13 is exposed to resemble a recessed mortar joint. - Referring to
FIG. 4 , there is shown a panel to panel abutment. Once again, like reference numerals are used to denote corresponding features. A panel to panel location and/or locking arrangement is shown with reference to 16. The arrangement further includes a retainingformation 17 formed on the first major edge which is adapted to inter-engage asecond retaining formation 18 formed on an innermost edge of thesecond recess 14 formed along the second major edge. In use, this arrangement serves to locate and retain each panel in an engaging alignment with an adjacent panel. - A representative dimension for an arrangement as depicted in
FIG. 4 includes having afirst recess 13 of about 40 mm wide and an upper limit in width of a second recess at about 25 mm. With such an arrangement, the depth of both recesses is typically approximately 50% of the panel thickness. It will be appreciated by those skilled in the art, however, that the depth and width of the recesses may be varied as desired and without undue practice to provide a wide range of desired aesthetic appearances and effects. -
FIG. 5 shows still another panel arrangement. The feature depicted inFIG. 5 is optional yet, when in use, allows for alignment adjustment during installation. The edge arrangement inFIG. 5 depicts a wedge formation 17 (on one edge) that includes awedge groove 18′. In addition there is rather parallel-lookingtongue arrangement 17′ (on the alternate edge) that is configured to engage acorresponding groove formation 18′ of an adjacent panel. A lead-inchamfer 18″ may be provided at the lowermost entry surface to thegroove formation 18′ to assist location of the adjacent plank and minimise the risk of damage. When lead-inchamfer 18″ is included, a similar mate may be provided as depicted at 17″. - A representative dimension for a panel as depicted in
FIG. 5 includes an upper limit in width of the first recess of about 43 mm and an upper limit in width of the second recess of about 28 mm. In one example, a length of bothtongue 17′ and groove 18′ is approximately 10 mm. It will be appreciated that this tongue and groove arrangement facilitates levelling of planks during installation and inhibits movement and reduces sound (e.g., rattling) of the planks when they are subjected to environmental changes, such as high winds. The facilitation is provided even when the tongue and groove formations are incompletely engaged. - Turning next to
FIG. 6 , there is shown, in perspective view, a joiningstrip 6 which is generally used to define a recessed joint intermediate two adjacent arrays.Strip 6 includes abase portion 19, which is adapted to be secured in a vertical orientation to a structural member such as a wall stud. In the centre of the joining strip there is a raisedrib formation 20 which will typically have a raised height less than panel 2 (as shown inFIG. 1 ) so that, when installed, an upper surface ofrib 20 provides an appearance of a recessed vertical masonry joint that corresponds closely with the depth of the recessed joint mimicked by thefirst recess 13 formed in each of the panels. - A joining strip of
FIG. 6 may also include anoptional lip formation 22 formed along one or both longitudinal edges.Formation 22 aids in the prevention of moisture that may enter a joint. Often moisture may migrate laterally into a cavity behind cladding. - A joining strip as described herein is preferably made of a thin sheet of metal or a durable plastic material. When assisted by
formation 22, it is understood thatformation 22 will be capable of deforming to some extent once the panels are installed. As such, a preferable material for a joining strip is one capable of some deformation. - A joining strip may also be configured as is shown in
FIG. 7 . With this configuration,base panel 19 andrib formation 20 remain are constructed generally as described withFIG. 6 .FIG. 7 also includes a self adhesivecompressive sealing strip 23 generally as shown in the figure. The compressive sealing strip may also be glued on and provide an alternative sealing mechanism to that disclosed inFIG. 6 asformation 22. When desired, both sealing features, compressive sealing strip andformation 22, may be included in a single joining strip. In still further embodiments, conventional sealing compounds are applied to the joining strip as the panels are installed. All such sealing features may be used in any combination as desired. -
FIGS. 10 to 13 show joining strips 6′ and 6″ that may be provided at a corner of a wall structure to enable one array of panels to be arranged transversely to another adjacent array of panels. Views of wall structures in which wall cladding as described herein have been installed are shown inFIGS. 14 to 17 , each of which shows various and representative joining strips identified as 6 a (FIG. 14 ), 6 b (FIG. 15 ), 6 d (FIGS. 16) and 6 c (FIG. 17 ). - In one or more embodiments, corner joining strips also include
longitudinal indentations 30 on at least one surface that act as nailing guides and/or capillary breaks for water ingress, as depicted representatively inFIG. 11 andFIG. 13 . -
FIGS. 10 and 11 show various views of one representative trim element. The trim element generally includes an externalcorner joining strip 6′ and having a substantially L- or V-shapedmember 24 that may be mountable to a structural member such as a corner stud member of a wall structure or frame. The external corner joining strip has a corner formation, preferably in the form of asquare tube 21, to provide the visual appearance of a box corner as shown inFIG. 15 . As shown inFIG. 11 , the external corner joining strip typically hasflange projections 22 extending from thesquare tube 21 to cover ends of panels that are positioned adjacent the square tube. -
FIGS. 12 and 13 show another representative trim element in the form of an internalcorner joining strip 6″ which is substantially L- or V-shaped. The corner of the “L” is inwardly stepped to provide acorner formation 23 having twosurfaces FIG. 17 . - Often, surface 25′ is typically wider than
surface 25, as illustrated inFIG. 12 . A difference in width will enable abutting ends of transversely arranged panels to partially overlap, resulting in a clean and neat visual appearance at the corner,. It will be appreciated that this is advantageous, as it is often difficult, if not impossible, to align corner edges of transversely arranged panels due to manufacturing tolerances in the panels and/or building creep. -
FIGS. 14 and 15 illustrate external corners andcorner joining strips FIGS. 16 and 17 illustrate internal corners and internalcorner joining strips - Corner joining strips are generally provided in the form of an L-shaped or V-shaped member with an extended or non-extended corner formation. With these embodiments and when desired, ends of the panels may be mitered to form a mitered corner by transversely abutting panels.
- Panels as described herein are made from any material having acceptable durability when exposed to the weather. In one form, the panels are fiber cement panels, shaped as desired and as described herein. Preferably the fiber cement is nailable. In many embodiments, a panel would have a length to width ratio greater than 4 and a length that corresponds to some multiple of conventional framing stud spacing for a desired regions in which the product is to be used. In Australia, one preferred length is about 4.2 m.
- It will be appreciated that this cladding system is designed with simplicity in mind and to be applied to virtually any structural wall structure (e.g., frame). Particularly suitable wall structures are those made of timber or metal. In use with such wall structures, and referring to elements as described and shown with
FIG. 1 , astrip 6 is first secured to a vertical stud member that defines an edge forarray 4. Afirst panel 2 is then positioned with itsend 9 abutting arib 20 and secured in a generally horizontal orientation to a series of adjacentvertical stud members 25. Where one of the overlapping panel embodiments are used, such as those shown inFIGS. 3 to 5 ),panel 2 should be oriented with a first major face facing outwards and a first recess uppermost. - panel as described above is generally secured to the underlying structural wall structure by any suitable means, which will depend on the wall structure and panel materials. For example, when cladding panels are made from a nailable material and the studs are a nailable material (e.g., timber or nailable metal), conventional nails are typically suitable for fixing said panels. Nails that may be concealed, such as brad style nails, may be preferred when desired. Where the width of the
recess 13 allows, fixing is preferably along that recess adjacent the outermost edge. This step, while not essential, ensures that the fixing will be concealed when the next panel is positioned on top. The spacing of the fixings along the length of the panel will generally be determined by stud spacing. Such spacing may vary and is typically that recommended by the desired manufacturer and/or by relevant building codes. - A second panel is positioned on top of the first and underlying panel, again with
ends 9 aligning withrib 20 onstrip 6, as illustrated inFIG. 1 . The prior step is repeated until an array has been completed. Multiple arrays are prepared as described for the single array. - In a representative example, a wall cladding is formed by first providing a wall structure or by constructing a frame. Often the frame is fully loaded and will include a suitable stud arrangement, such as double 45 mm studs, double 35 mm studs separated by 15 mm packers and/or triple 35 mm stud, at all vertical joints. When desired, a vapor permeable membrane may be installed with a suitable overhang. Set up datum line; the datum will typically be the bottom edge of the first panel; the datum line should be square to vertical flashing stops and square to the bottom edge of the first panel. A sealant may be applied inside fastener locations. A first board is positioned to provide a suitable overhang, which is often 20-50 mm. Fixing of the first board to a bottom plate may be performed. Panels should be suitably arranged so at to be appear locked in firmly. A second panel is then fixed and before fitting a third panel until all remaining panels are fixed. Preferably, each panel is made level and the height of each row of panel is kept the same. When desired, a joint sealant may also be applied to each panel at the joint just prior to installation of each panel.
- When desired, panels may be joined on and off stud without the use of a vertical flashing stop to create a traditional butt join. In some embodiments and to maximize strength and aesthetic features, butt joins may be staggered over two or more stud lines (e.g., do not locate joints in the same vertical line).
- At vertical joints, vertical flashing stops may be used and fixed to studs. The rear of each panel may then be adhered to a vertical flashing strip using a suitable joint sealant, when desired.

Where the wall is designed to include one or more openings, such as windows or doors,panels 2 are readily cut to fit, as required. - hose skilled in the art will appreciate that the cladding system described herein may be used to achieve any aesthetic effects desired. For example, each panel shown in
FIG. 8 are prepared to include a corner detail at its corner end to achieve a faux stone block effect that will replicate the appearance of a corner of a colonial style sandstone building. In one or more embodiments, one or more corner details of a cladding system described herein is provided in two-dimensional form by colouration of the end of the panel. In other embodiments, the corner detail is achieved in a three-dimensional form by a decorative arrangement, such as quoining, which may include fixing a further portion of cladding to the end of the panel. The further portion of cladding may be detailed by colouration or with some other visual or decorative detail, such as an engraving or pattern. The ends of the further portion of cladding may be mitered to provide a visual appearance at the corner as shown inFIG. 8 . - Referring now to
FIG. 9 , a further aesthetic effect is illustrated. The effect is achieved using a cladding system described herein as part of acomposite wall system 90 in whichupper section 96 andlower section 98 ofcomposite wall 91 are formed of a conventional rendered panel construction and a middle section of the wall is formed with acladding system 91 as described herein that includes a plurality ofpanels 92 formed in anarray 94. External walls constructed a cladding described herein may include additional features, such as decorative arrangements, coloration, and/or patterning. The cladding system is fully compatible with insulation materials. - It will be appreciated that a masonry replica cladding system as described herein may be used to form only a part of a complete cladding system. For example, a complete cladding system may include several panels that have been cut to fit around a door or window such that ends of these panels do not align with the ends of other panels. A complete cladding system may further include masonry.
- It will also be appreciated that while the preferred embodiment described is mounted directly to a frame structure, the system can also be used on housing structures which already include some form of board or cladding fixed onto the building frame. For example, the system may be installed over battens or directly onto a masonry wall.

In this manner, each installed panel may be retained by the overlapping edge of an adjacent panel.
- The recess in the first major face of each panel adjacent the corresponding first major edge is of sufficient width to facilitate fixing of the panel on an inner portion of the first recess such that in use the fixing will be concealed by an overlapping second major edge of an adjacent panel.
- The first recess in the first major face of each panel may further include a retaining formation adapted to inter-engage a corresponding retaining formation on an innermost edge of the second recess formed on the second major face, which in use operates to locate and retain each panel in engaging alignment with an adjacent panel. Inter-engaging portions may be in the form of corresponding wedge formations or other mated extensions.
- Each end of each panel preferably includes as a substantially planar abutment surface at all or a portion the surface. The planar abutment surface may be a squared end of the associated panel or may be a mitered end of the associated panel. In use, planar abutment surfaces of ends of each panel in the array of panels are substantially aligned to form an edge abutment surface of the array. Preferably, the edge abutment surface is substantially planar.
- The cladding system may also include one or more trim elements for providing a weather-proof joint for at least one side edge of each array formed by the adjacent panel ends. In one form, the trim element comprises a thin strip of material (sometimes in the form of a sheet) having a central portion that extends between the aligned ends of two arrays of adjacent panels. The trim element may be designed to replicate a base of a recess that corresponds closely to the depth of the first recess formed in the first major face of each panel.
- The trim element may also be provided at one or more corners as a corner trim element and facilitate a transverse arrangement of two arrays of panels. A corner trim element may be an internal corner trim element and/or an external corner trim element. The corner trim element may be a substantially L-shaped or V-shaped member and made capable of mounting to a structural member. A corner formation of the trim element may be arranged in one of a number of arrangements. In one form, the corner trim element may allow side edges of a first array of panels and side edges of a second array of panels to form a mitered corner when said panels abut. In addition, panels of transversely arranged arrays may be butt jointed. A trim element may be further arranged to reside between two sets of transverse panels (or arrays) such that each panel (or array) forms a butt joint against the trim element. rather than against each other.
- A corner trim element may also include a corner formation against which the side edge of a first array of panels and a side edge of a second transverse array of panels can be aligned such the two arrays are arranged transversely to each other. The corner formation may be configured to provide a desired aesthetic effect for the corner. In some embodiments, a corner formation may be a square tube for providing a box corner.
- A trim element may be elongate. The trim element may act as a corrosion resistant flashing. A suitable material for a trim element is aluminium. However, other materials, as described previously are similarly suitable.
