Description

WO 2008/030114 PCT/NZ2007/000255 A FIXING SYSTEM FOR CLADDING FIELD OF THE INVENTION 5 The present invention relates to a fixing system for cladding. In particular, although not exclusively, the fixing system may be utilised to secure weatherboards to the walls or framing of buildings. The fixing system also has applications in relation to fencing, screens, and roofing. 10 BACKGROUND TO THE INVENTION There are numerous weatherboard designs on the market. The most important feature of a weatherboard design is its cross-sectional profile. This profile dictates the way in which the weatherboards should be installed and the overall appearance of the weatherboard cladding 15 after installation. Commonly, weatherboards are designed to be installed in an overlapping relationship with each other and can be fixed horizontally, vertically or on an angle. Further, .some weatherboard designs include grooves that, when installed, cooperate with the grooves of overlapping like weatherboards to provide anti-capillary channels. Such channels prevent moisture from getting in behind the weatherboards and causing damage. 20 Figures 1 and 2 show cross-sectional and front views of a known weatherboard design 10. The rear surface 11 of the weatherboard 10 has a sloped portion 12 that is arranged to abut the framing 16 of a building when installed and this enables like weatherboards to be installed in a partial overlapping relationship with each other as shown in Figure 3. 25 Weatherboards having this design are also provided with wide grooves 13 and 14 along the front 15 and rear 11 surfaces respectively. When such weatherboard cladding is installed, the grooves of each weatherboard cooperate with the grooves of overlapping weatherboards to create anti-capillary channels 17 shown in Figure 3. 30 During installation, the weatherboards shown in Figures 1-3 are typically fixed to the framing 16 one at a time from the bottom up such that the weatherboards are parallel and have an even overlap up the framing. One method of aligning the weatherboards is to ascertain the required level and then rest the next weatherboard to be installed on a line of 1 WO 2008/030114 PCT/NZ2007/000255 nails partially nailed in, which are removed once the weatherboard has been nailed into place. Referring to Figure 4, it has become increasingly common for cavity battens 19 to be 5 provided between the framing 16 and weatherboards 10. The battens 19 create cavities between the framing 16 or wall of the building and the weatherboards 10 and these cavities provide a drainage path for water and/or moisture that may penetrate in behind the weatherboards. The use of cavity battens is particularly desirable in coastal properties or buildings that are situated in exposed areas that have harsh weather conditions. The cavity 10 battens are used to form drainage channels and the increased drainage allowed by the cavities reduces the likelihood of water or moisture penetrating the framing cavity, the cause of internal structural and interior lining rotting and decay. In this specification where reference has been made to patent specifications, other external 15 documents, or other sources of information, this is generally for the purpose of providing a context for discussing the features of the invention. Unless specifically stated otherwise, reference to such external documents is not to be construed as an admission that such documents, or such sources of information, in any jurisdiction, are prior art, or form part of the common general knowledge in the art. 20 It is an object of the present invention to provide an improved fixing system for cladding, or to at least provide the public with a useful choice. SUMMARY OF THE INVENTION 25 In a first aspect, the present invention broadly consists in a fixing system for securing cladding boards to the framing of a building in a partially overlapping relationship, each board having front and rear faces with a recess being provided in and along the rear face, the fixing system comprising: a plurality of fixing devices, supported by the framing, that 30 are spaced apart relative to one another and arranged in rows, each row of fixing devices being arranged to support a board or row of boards and each fixing device having an engagement portion that is arranged to engage with a section of the recess of a board to, in co-operation with a number of other fixing devices of that row also engaging with a section 2 WO 2008/030114 PCT/NZ2007/000255 of the recess, support the board in place on the framing; and a plurality of fixing components that are arranged to extend through the front face of each board within the overlapping region of adjacent boards and into the framing to secure each board to the framing in co-operation with the fixing devices. 5 In one form, the fixing devices are provided in integral strips that are secured to the framing for receiving the boards, each strip being provided with a number of integral fixing devices spaced apart along its length, and the strips being spaced apart and aligned on the framing in a vertical orientation relative to each other to provide rows of fixing devices on 10 the framing for supporting rows of boards. Preferably, the fixing devices are spaced apart along the length of the strips by a uniform predetermined distance that is calculated based on the height of the boards and a uniform desired board overlap distance so that each row of boards has a corresponding row of fixing devices. 15 In another form, the fixing devices are individually attached directly to the framing in a spaced apart arrangement vertically and horizontally with respect to each other on the framing to form rows of fixing devices on the framing for supporting rows of boards. In yet another form, the fixing devices are provided on battens that are secured to the 20 framing for receiving the boards, each batten being provided with a number of fixing devices spaced apart along its length, and the battens being spaced apart and aligned on the framing in a vertical orientation relative to each other to provide rows of fixing devices on the framing for supporting rows of boards. 25 Preferably, the fixing devices are spaced apart along the length of the battens by a uniform predetermined distance that is calculated based on the height of the boards and a uniform desired board overlap distance so that each row of boards has a corresponding row of fixing devices. In one form, the fixing devices are integrally formed with the battens. In another form, the fixing devices are individually attached directly to the battens. In yet 30 another form, the fixing devices are integrally formed in integral strips that are fixed to the battens. Preferably, the battens each comprise an elongate base member that is attached along its 3 WO 2008/030114 PCT/NZ2007/000255 length to a corresponding top plate, the top plate being provided with a number of integral fixing devices spaced apart along its length. Preferably, the engagement portions of the fixing devices are shaped to engage or co 5 operate with a complementary recess in the rear face of the boards to thereby act to, in co operation with a number of other fixing devices of that row also engaging with the recess, support the board in place on the framing. In one form, each fixing device is a wedge-shaped component having an engagement 10 portion for engaging with the recess of a board. Preferably, each fixing device has a substantially wedge-shaped cross-sectional profile formed by a base end from which a rear face and a front face extend, the front face being inclined relative to the rear face such that the front and rear faces meet to form a pointed top-end opposite the base end and wherein the front face is designed to abut a rear face of the board and has an engagement portion 15 that protrudes from the front face at or toward the base end for engaging with a recess in the rear face of the board. More preferably, the engagement portion of the fixing device is a tapered protrusion the end-point of which is arranged to extend upward and outward at an angle from the front face of the fixing device, the recess of the boards having a complementary inclined surface for receiving the tapered protrusions in a hook-like 20 engagement relationship to enable the boards to be supported on the framing by the fixing devices. In an alternative form, each fixing device is a bracket-type component having an engagement portion for engaging with the recess of a board. By way of example, each 25 fixing device has a substantially L-shaped cross-sectional profile formed by a base portion that is arranged to extend outwardly relative to the framing and an engagement portion that extends upwardly from the base portion and which terminates with a hooked-end edge that bends toward the framing, the recess of the boards being arranged to receive the engagement portion of the fixing device and having a complementary inclined surface for 30 receiving the hooked end edge of the engagement portion in a hook-like engagement relationship to enable the boards to be supported on the framing by the fixing devices. Alternatively, each fixing device has a substantially U-shaped cross-sectional profile formed by: a rear portion being arranged for securing directly or indirectly to the framing; a base 4 WO 2008/030114 PCT/NZ2007/000255 portion extending outwardly from the bottom of the rear portion; and a front engagement portion that extends upwardly from the base portion and which terminates with a hooked end edge that bends toward the rear portion, the recess of the boards being arranged to receive the engagement portion of the fixing device and having a complementary inclined 5 surface for receiving the hooked end edge of the engagement portion in a hook-like engagement relationship to enable the boards to be supported on the framing by the fixing devices. Preferably, the portions of each fixing device are integrally formed with each other. Preferably, each board is provided with grooves along its front and rear faces and is 10 arranged to abut another board in a partially overlapping relationship when installed on the framing such that the grooves of the front and rear faces co-operate to form a channel, the fixing components being arranged to extend through the front face of each board and into the framing within the overlapping region of adjacent boards but under the respective channels to secure each board to the framing in co-operation with the fixing devices. 15 Preferably, the fixing components are arranged to extend through the front face of each board within the overlapping region and into the framing behind each board such that the fixing components are concealed underneath the overlapping portion of an adjacent board. 20 Preferably, the fixing components are selected from the following: nails, screws, or staples. In a second aspect, the present invention broadly consists in a fixing device for holding cladding boards in place on framing, each board having front and rear faces, a recess being provided in and along the rear face, and being arranged to be installed on the framing in a 25 partially overlapping relationship with other like boards, the fixing device being arranged to co-operate with a number of like fixing devices such that the fixing devices are supported by the framing and are spaced apart relative to each other and arranged in rows, the fixing device having an engagement portion for engaging with a section of the recess of a board to, in co-operation with the other fixing devices of that row also engaging with a section of 30 the recess, hold the board in place on the framing. Preferably, the fixing device is arranged to be securely attached directly or indirectly to the framing. 5 WO 2008/030114 PCT/NZ2007/000255 In one form, the fixing device is a wedge-shaped component having an engagement portion for engaging with the recess of a board. Preferably, the fixing device has a substantially wedge-shaped cross-sectional profile formed by a base end from which a rear 5 face and a front face extend, the front face being inclined relative to the rear face such that the front and rear faces meet to form a pointed top-end opposite the base end and wherein the front face is designed to abut a rear face of the board and has an engagement portion that protrudes from the front face at or toward the base end for engaging with a recess in the rear face of the board. More preferably, the engagement portion is a tapered protrusion 10 the end-point of which is arranged to extend upward and outward at an angle from the front face of the fixing device, the recess of the boards having a complementary inclined surface for receiving the tapered protrusions in a hook-like engagement relationship to enable the boards to be held on the framing by the fixing devices. 15 In an alternative form, the fixing device is a bracket-type component having an engagement portion for engaging with the recess of a board. By way of example, the fixing device has a substantially L-shaped cross-sectional profile formed by a base portion that is arranged to extend outwardly relative to the framing and an engagement portion that extends upwardly from the base portion and which terminates with a hooked-end edge that bends toward the 20 framing, the recess of the boards being arranged to receive the engagement portion of the fixing device and having a complementary inclined surface for receiving the hooked end edge of the engagement portion in a hook-like engagement relationship to enable the boards to be held on the framing by the fixing devices.

Preferably, the fixing devices are spaced apart along the length of the battens by a uniform 15 predetermined distance that is calculated based on the height of the boards and a uniform desired board overlap distance so that each row of boards has a corresponding row of fixing devices. In one form, the fixing devices are integrally formed with the base member of the batten. 20 In another form, the fixing devices are individually attached directly to the base member of the batten. In yet another form, the fixing devices are integrally formed in integral strips that are fixed to the base member of the batten. Preferably, the batten further comprises a top plate that is attached to the base member 25 along its length, the top plate being provided with a number of integral fixing devices spaced apart along its length. In one form, each fixing device is a wedge-shaped component having an engagement portion for engaging with the recess of a board.

The weatherboards are arranged to be installed on framing or walls of a building in a partially overlapping relationship and are preferably provided with grooves on the front and rear faces that, when installed, co operate to form an anti-capillary channel in the overlapping region of two adjacent 15 weatherboards. It will be appreciated that there are many different weatherboard or cladding board designs that could provide for the overlapping relationship and the channel, and these alternative designs are all intended to be included within the scope of the present invention. Further, the fixing system will work with boards that are not designed to form anti-capillary channels. 20 In general, the present invention relates to a concealed fixing system for securing cladding boards to the framing or walls of a building. The fixing system is entirely concealed when the boards are installed. The fixing system comprises rows of spaced apart fixing devices supported, directly or indirectly, by the framing or wall, each row of fixing devices being 25 arranged to support a board or row of boards via engagement into a complementary recess provided in the ear face of each board. The fixing system preferably also utilises a number of fixing components that extend through the front face of each board along an upper edge of the board -in the overlapping region between adjacent boards and into the framing to secure the boards to the framing. The fixing devices can be provided on cavity battens that 30 are secured to the framing of the building or they may be directly connected to the framing. Referring to Figures 5-8b, a first preferred form of the fixing system of the invention will be described by way of example. Referring to Figures 5 and 6, the first preferred form of 14 WO 2008/030114 PCT/NZ2007/000255 the fixing system 20 comprises a number of elongate cavity battens 22 that are attached or secured to the exterior surface of a wall 24 (Figure 5) or framing 26 (Figure 6) upon which a number of cladding boards 28 are installed in an overlapping relationship. The cavity battens 22 may be attached or secured to the wall 24 or framing 26 via fixing components 5 such as nails or screws, or adhesive, or any other fixing means. The battens 22 are preferably installed in a vertical orientation and are spaced apart along the wall 24 or framing 26. They are also preferably aligned to form rows of fixing devices 30. Each cavity batten 22 is provided with a number of fixing devices 30 spaced apart along its 10 length. The fixing devices 30 include an engaging portion that is shaped to engage with or into a section of a complementary recess provided in and along the rear face of a board. The cavity battens 22 are arranged such that, when installed, the fixing devices 30 form rows, each row of fixing devices 30 being arranged to engage into a board or row of boards to hold the board or boards in place against the battens and/or framing. In particular, a 15 number of fixing devices 30 of a row are arranged to co-operate together to engage in sections of the complementary recess of a board to hold the board in place against the wall 24 or framing 26. Referring to Figure 7, the fixing devices 30 and their relationship with the recesses of the 20 boards will be described in more detail. The fixing devices 30 of the first preferred form of the fixing system are of a wedge type. In particular, they preferably have a cross-sectional profile that is substantially wedge-shaped with a base end 32 that tapers into a pointed top end 34. More specifically, the cross-sectional profile of the fixing device 30 comprises a flat rear face 36 and an inclined front face 38 which meet at the pointed top-end or edge 25 34. In the preferred form, the front face 38 of the fixing device 30 is arranged to abut a rear face of a board 28. Protruding from the front face 38 toward the base end 32 is an engaging or engagement portion 40 that is shaped to securely engage or co-operate with a complementary recess 42 provided in and along the rear face of a board 28. In particular, the engaging portion 40 may be shaped such that it hooks into the recess 42 of the board 30 to thereby support the weight of the board and hold it in place against the cavity battens 22 and framing 26. In the preferred form, engagement portion 40 includes a tapered protrusion 40a, the end point of which is arranged to extend upward and outward at an angle from the front face of the fixing device 30. 15 WO 2008/030114 PCT/NZ2007/000255 In the preferred form, the recesses 42 of the boards 28 are preferably provided with a complementary inclined or angled surface 42a for receiving the tapered protrusion 40a of the fixing device in a hook-like engagement relationship to enable boards to be supported 5 on the framing. With reference to Figure 7, the recess 42 of the board 28 may, for example, have a cross-sectional profile that comprises a lower surface 42c that extends substantially perpendicularly into the board from and relative to the rear face of the board, and then a back surface 42d extending upwardly from the lower surface. The inclined upper surface 42a may then extending downwardly from the top of the back surface 42d back toward the 10 rear face of the board 28 to complete the recess. In the preferred form, the angled upper surface 42a and rear face together form a tapered upper edge 42b that points downwardly and outwardly relative to the rear face for engaging in a hook-like engagement relationship with the tapered protrusions 40a of the fixing devices. 15 The fixing system 20 further preferably comprises a number of fixing components 44 that extend through the front face of the boards 28 toward and along the upper edge of each board and into the cavity battens 22 and framing 26 to secure each board in place. It will be appreciated that a number of fixing components 44 may be provided along the length of each board at appropriate places. The fixing components 44 may be nails, screws, or the 20 like, and are located in the overlapping region of two adjacent boards so that they are concealed. Preferably, the fixing components 44 are inserted below the anti-capillary channel 46 formed by the co-operating grooves of the overlapping boards 28. Alternatively the fixing components may be inserted above the channel 46 or they may be inserted anywhere in the overlapping region if the boards do not provide anti-capillary 25 channels. Referring to Figures 8a and 8b, a cavity batten 22 is shown in isolation and will be explained in more detail. Each cavity batten 22 comprises an elongate base member 48 having a number of fixing devices 30 spaced apart along its length. The fixing devices 30 30 are identical in profile and are spaced apart on the batten 22 by a uniform predetermined distance that corresponds to the dimension of the boards being installed and the desired overlap required for the boards. In particular, the predetermined spacing distance between the fixing devices is calculated based on the height of the boards 28 and a uniform desired 16 WO 2008/030114 PCT/NZ2007/000255 board overlap distance to enable rows of fixing devices to be formed during installation of the battens, one row of fixing devices for each row of boards. It will be appreciated that the fixing devices may be integrally formed with the elongate base member 48. For example, the cavity batten may be formed from wood and may be profiled or cut to 5 provide a plurality of fixing devices 30 on its front face. Alternatively, it will be appreciated that the fixing devices 30 may be individually formed and cut and attached individually to the base member 48 of the cavity batten 22 via adhesives, nails, screws, or other fixing means. It will be appreciated that the cavity batten may be formed as one uniform integral component or by an interconnection of the base member 48 and a number of fixing 10 devices 30. The battens may be formed from any suitable type of material, such as wood, plastic, metal, steel or any combination thereof. The battens may be any desired length as required. As mentioned, it is desirable to utilise cavity battens to provide cavities in between the 15 cladding boards and framing for drainage purposes, especially when the cladding boards are likely to be exposed to particularly harsh weather conditions. However, an alternative to the first preferred form of the fixing system 20 may be employed that does not utilise cavity battens. In particular, the fixing devices 30 may be directly attached to the framing 26 of the building such that they are spaced apart vertically and horizontally on the face of 20 framing to form rows, each row being arranged to receive and retain an individual cladding board or row of boards. For example, Figures 9a and 9b show an alternative form of the first preferred form of the fixing system 20 that does not utilise cavity battens. Rather, it utilises fixing devices 30 that are directly coupled or connected to the framing 26 with fixing components such as screws, nails, or the like. Figure 9a shows a single framing 25 component 26, such as a stud or strut, with directly connected fixing devices 30 and Figure 9b shows a number of cladding boards 28 installed onto the framing 26. Like Figure 7, fixing components 44 are provided in the overlapping region extending through the front face of each board 28 and into the framing 26 to provide additional securement of the cladding boards to the framing. 30 Another alternative form of the first preferred form of the fixing system 20 that can be used without cavity battens is shown in Figure 9c. In this form, the fixing devices 30 may be formed in integral plates or fixing strips 30a of any desired length and from metal, steel, 17 WO 2008/030114 PCT/NZ2007/000255 plastic, wood or any other suitable material. These strips 30a can be directly attached to the framing with nails, screws, staples, adhesive or any other fixing means to form the rows of fixing devices on the framing. 5 Referring to Figures 10a and 10b, a second preferred form of the fixing system of the present invention will be described. The second preferred form of the fixing system 60 is substantially similar to that of the first preferred form, but differs in that the fixing devices are bracket-type components rather than wedge-type components. 10 Referring to Figure 10a, the cavity battens 62 of the fixing system 60 comprise an elongate base member 64 on to which is attached a top plate 66. The top plate 66 is provided with a number of connection apertures 68 through which fixing components such as screws 70, nails, or the like may extend to fix the cavity batten 62 to the framing 26 as shown in Figure 10b. It will be appreciated that screws, nails, or other fixing components may 15 extend through these apertures 68 to couple the top plate 66 to the base member 64 or alternatively the top plate may be connected to the base member 64 via adhesives such as glue or the like. In the preferred form, the top plate 66 is punched along its length to form bracket-type 20 fixing devices 72 that are shaped to engage with complementary recesses 76 in the rear faces of cladding boards 67 as shown in Figure 10b. In particular, the bracket-type fixing devices 72 may have a substantially L-shaped cross-sectional profile. For example, the fixing devices 72 may comprise a base portion 72a that is arranged to extend outwardly relative to the batten 62 and an integral engagement portion 72b that extends upwardly 25 from the base portion 72a and which terminates with a hooked-end edge 74 that bends toward the batten. In operation, the engagement portion 72b and hooked-end edge 74 are arranged to engage with a complementary inclined surface 78 of the recess 76 of the cladding board 67 in a hook-like engagement relationship to hold the board in place on the batten and framing. 30 Other than the bracket-type nature of the fixing devices 72, the fixing system 60 operates in a similar manner to that described in respect of the first preferred form of the fixing system 20. For example, concealed fixing components such as nails, screws, or the like are 18 WO 2008/030114 PCT/NZ2007/000255 provided in the overlapping region of the cladding boards 67 to secure them to the battens 62 and framing 26 for additional support. It will be appreciated that the bracket-type fixing devices 72 may be formed in other ways 5 and do not necessarily have to be integrally provided by a single top plate 66. For example, individual bracket-type fixing devices may be individually attached or secured along the length of the base member 64 of the cavity batten 62 at spaced apart intervals. The cavity batten 62 may be formed from wood, plastic, metal or a combination thereof. For example, it may have a wooden base member 64 and a metal top plate 66 having metal 10 integral fixing devices 72 or alternatively the top plate 66 may be plastic. The base member 64 does not necessarily have to be wood and could also be plastic or metal. In an alternative form of the fixing system 60, the bracket-type fixing devices may be provided on the framing without cavity battens. For example, individual bracket-type 15 fixing devices 80 may be secured directly to the framing in rows via fixing components 82, such as screws, nails, or the like as shown in Figures 11a-1 1c. The individual fixing devices 82 of the bracket-type will be explained in more detail with reference to Figure 11c. In the preferred form, the fixing devices 82 have a substantially U 20 shaped cross-sectional profile that is formed by shaping or bending a flat metal component. For example, the fixing devices 82 comprises a rear portion 84 and a front engagement portion 86 that are integrally joined at the bottom by a base portion 88 to create a substantially U-shaped bracket. In the preferred form, the front engagement portion 86 terminates with a hooked-end top edge 90 that bends toward rear portion 84. 25 In operation, the front engagement portion 86 and hooked edge 90 are arranged to securely engage with a section of the recess and its inclined upper surface of a cladding board as previously described in a hook-like engagement relationship. The rear portion 84 is provided with an aperture 92 through which a fixing component 82, such as a screw, nail, or the like, may extend to secure or attach the fixing device to framing or the like. 30 In another alternative form of the fixing system 60, the bracket-type fixing devices may be formed in integral plates or fixing strips 94 as shown in Figure 12. These strips 94 can be directly attached to the framing with nails, screws, staples, adhesive or any other fixing 19 WO 2008/030114 PCT/NZ2007/000255 means to form the rows of fixing devices on the framing without using cavity battens. The strips 94 may be any desired length and may be formed from metal, steel, plastic, wood or any other suitable material. By way of example, the strips 94 may be essentially the same as the top plates 66 described with reference to Figures 10a and 10b, and like features have 5 like reference numerals in Figure 12. Installation of cladding boards utilising the fixing system of the present invention will now be described. Firstly, the cavity batten based fixing systems described with reference to Figures 5, 6, 7, 8a, 8b, 10a and 10b will be described. Referring to Figure 6 by way of 10 example, installation involves firstly fixing a number of cavity battens 22 to the framing 26 of the building in a vertical orientation at spaced apart intervals. These intervals can be lengthened or shortened as desired and they do not necessarily have to be uniform. The cavity battens 22 are installed such that that fixing devices 30 provided on each cavity batten are aligned with the fixing devices of the other cavity battens to form rows of fixing 15 devices. Installation then involves fixing cladding boards 28 to the cavity battens so that the boards have an overlapping relationship with respect to each other. For example, a top portion of a lower board should be covered by a lower portion of the next highest board, with all boards preferably in a parallel configuration with even overlap. 20 Typically, the boards 28 are fixed to cavity battens 22 one at a time beginning at the bottom of the framing 26 where the cladding is to start. Typically, the lower-most board is installed first by being engaged against the lower-most row of fixing devices such that a number of the fixing devices of that row engage securely in sections of the complementary recess in the rear face of the board. With the board 28 held in place against the cavity 25 battens 22 by a number of fixing devices, a number of fixing components, such as nails, screws, staples, or the like, can be inserted or driven through the front face and toward the top edge, and preferably under the anti-capillary groove, of the board 28 and into the battens 22 and/or framing 26 to secure the board in place. With the lower-most board in place, the next board may be positioned against the cavity battens such that its rear face 30 recess engages with a number of fixing devices of the next row and it may then also be nailed in place. The vertical spacing between the rows of fixing devices is preferably uniform and predetermined to ensure an even overlap of boards up the framing. The overlap also conceals the nails inserted below the anti-capillary channel. Each subsequent 20 WO 2008/030114 PCT/NZ2007/000255 board is installed in a similar manner until the cavity battens and/or framing of the building is fully covered. Installation of cladding boards utilising the fixing system described with respect to Figures 5 9a, 9b and 11a-11c is similar but more labour intensive. In particular, rather than simply installing a number of cavity battens upon the framing in a spaced apart manner, individual fixing devices, whether wedge-type (Figures 9a and 9b) or bracket-type (Figures 11a-11c), must be fixed to the framing in a spaced apart manner vertically and horizontally to create aligned rows of fixing devices, each row being arranged to support a board or row of 10 boards. Installation of the cladding boards utilising the fixing system described with respect to Figures 9c and 12 is similar to that described with respect to the cavity batten based fixing systems. In particular, the integral fixing strips 30a (wedge-type - Figure 9c) or 94 (bracket 15 type - Figure 12) of fixing devices are attached directly to the framing and aligned on the framing in a similar manner to the cavity battens 22 to form rows of fixing devices. It will be appreciated that the fixing devices may be formed from various materials and that there are various alternative complementary shapes of fixing devices and cladding board 20 recesses that could be utilised to engage with each other to hold cladding boards in place. The wedge-type and bracket-type fixing devices described are provided by way of example only. It will be appreciated that the vertical and horizontal spacing between fixing devices, 25 whether installed via cavity battens or directly to framing, may be varied as desired to accommodate different framing structures, cladding board sizes and the like. Preferably, the vertical spacing intervals between fixing devices is uniform to provide an even overlap of boards up the framing. The horizontal spacing intervals can be varied according to the desired level of structural integrity required. 30 The fixing system of the present invention provides greater stability in the construction of cladding board buildings and houses. The fixing devices of the fixing system are designed to hold boards in place, with nails or the like providing additional securement at intervals 21 WO 2008/030114 PCT/NZ2007/000255 through the unexposed surface of the boards in the overlapping region. The fixing system provides greater stability of boards and provides greater resistance against the elements as it is an entirely concealed fixing system. The concealed nature of the fixing system also provides an aesthetic advantage in that there is no visible nailing. Also, boards can be pre 5 painted prior to installation on the framing and this may provide cost savings from an installation viewpoint. Further, the cavity batten based fixing system provides a means of enhancing the durability and life of cladding via increased drainage. The fixing system has been described in the context of cladding the framing of a building, 10 but it will be appreciated that the system can also be applied to roofing, fencing, and screens, whether the framing is timber or metal. It will also be appreciated that the boards of the cladding system can be installed horizontally, vertically or on an angle. The foregoing description of the invention includes preferred forms thereof. 15 Modifications may be made thereto without departing from the scope of the invention as defined by the accompany claims. 22
