    1 IMPROVED SEALING DEVICE Field of the Invention [0001] This invention relates to an improved sealing device for use in sealing between profiled panels, such as roofing panels. Background of Invention [0002] In our co-pending Australian patent application AU2009202866, there is disclosed a sealing device for sealing between profiled steel roofing panels of a long span roof. In the context of that application and the present application the term "long span" refers to an industrial roof that may, for example, be up to 80 metres long and have a small fall angle to enable rainwater run-off which can be as low as 10. The present invention is directed to providing an alternative form of sealing device suitable for use in conjunction with the sealing device of patent application AU2009202866. [0003] A long span roof enables the use of profiled roofing panels of up to about 80 metres in length. However, despite such panels being installed with a small fall angle as low as 1 , it can be beneficial to incorpo rate transparent or translucent panels of plastics material in selected areas of the roofing. The plastics panels may for example be of polycarbonate, PVC or fibre-reinforced plastics, such as fibreglass. As with the profiled metal panels, the plastics panels may be profiled. In this case, the term "profiled" most preferably indicates panels shaped to provide longitudinal ribs with a pan between laterally successive ribs. In a preferred form, at least for the metal panels, the ribs tapering towards their top, but having stepped side walls so as to be somewhat mushroom shaped in end elevation. However, plastics profiled panels are relatively expensive and in more readily available types, have ribs that are curved and somewhat semi-circular in end elevation, or more box-like in having substantially parallel or mutually inclined side walls and a domed or flat top. [0004] A sealing device according to patent application AU2009202866, for use providing a seal between the ends of overlapping profiled panels such as roofing panels, has an elongate body which, relative to one in-use orientation, has upper and lower longitudinal surfaces and laterally outwardly facing longitudinal side surfaces. In side elevation relative to that orientation the sealing device defines, at one or more SPCN-966549 2 locations along its length, an engagement portion at which the upper surface is raised, and at which the lower surface is raised and preferably recessed, and each of the lower and the upper surfaces of the engagement portion has a respective form which at least in part corresponds to the form in cross-section of the outer, upper surface and the inner, lower surface of profiled ribs of longitudinally overlapping profiled panels with which the sealing device is to be used. The body of the sealing device may have a length substantially equal to the spacing between at least two successive profiled ribs of the profiled panels, with each end of the body co-operable with an end of successive other end-to-end sealing devices to form an engagement portion for sealing between the abutting ends. [0005] For use with profiled panels with side margins of an inter-fitting form enabling laterally adjacent panels to co-operate to form a rib, with the panel having at least one profiled rib which is spaced from a side margin or next adjacent rib by a pan or trough of a standardised width, the sealing device of patent application AU2009202866 may have: e a body of a length corresponding substantially to the width between side edges of the profiled panel with which it is to be used; e respective end portions of the body each able to abut end-wise an end portion of another in-line sealing device so the abutting end portions have the form of an engagement portion; * intermediate of the end portions, at least one engagement portion; and e a spacing portion of the body by which one engagement portion is spaced from an end portion or a next adjacent engagement portion. [0006] An end to end series of the sealing devices may have the appearance of a uniform series of engagement portions substantially uniformly spaced by spacing portions of the bodies. The raised upper surface and the recessed lower surface at each engagement portion preferably have substantially complementary forms which correspond substantially to the cross-sectional profile of the lower, inner surface and the upper, outer surface, respectively, of profiled ribs of the profiled panels. SPCN-966549 3 [0007] The device of patent application AU2009202866 principally is intended for use with profiled panels having a rib form defining a channel of a re-entrant shape in cross-section, to provide a rib form of a hollow, mushroom shape. Thus, the raised upper surface and the recessed lower surface most preferably having a form which corresponds to, and is the complement of the mushroom shape of, the rib. Such forms enable the device to be forced down against a lower profiled panel to locate a head portion of a rib of the lower panel within the recessed lower surface of the clip, and enabling an upper profiled panel to be forced down against the device to locate the raised upper surface of the device in a head portion of the channel of the upper profiled panel. [0008] With a sequence of three laterally successive panels in which a plastics panel is supported at each side by a respective metal panel, respective sealing devices may co-operate to provide a seal at a composite rib formed by a side margin of successive panels. However if each sealing device is in accordance with patent application AU2009202866, difficulty can be encountered in achieving a sound, water tight seal at the composite rib along each side of the plastics panel. This is despite the sealing device being formed at least in part of a resilient material, such as resilient foam material. [0009] With a composite rib formed between successive metal panels, the composite rib is formed by inter-fitting complementary side margins of the metal panels. The inter-fitting is such that the composite rib has the same overall form as the other ribs of these panels, such as of the above-mentioned hollow mushroom shape. A composite rib formed between a metal panel and a plastics panel usually is of a more simple form due, at least in part, to the need for the plastics panel to be supported between two metal panels. Thus, the composite metal/plastics rib has a lower inner surface determined partly by the side margin of the metal panel and partly by the side margin of the plastics panel, and an upper outer surface determines mainly by the side margin of the plastics panel. The side margin of the plastics panel may, and usually does, comprise a substantially complete rib and therefore substantially fully covers and is supported on, the side margin of the metal panel. [0010] Unless there is used a plastics panel of substantially the same profiled shape as the metal panel, such as with mushroom shaped ribs, an option giving rise SPCN-966549 4 to very substantial added costs, there is a need for an alternative form of sealing device, and the present invention addresses that need. Summary of Invention [0011] A sealing device according to the present invention (hereinafter called the "general" device or sealing device) has an elongate body which, relative to one in use orientation, has upper and lower longitudinal surfaces and laterally outwardly facing longitudinal side surfaces. In side elevation relative to that orientation, the general device defines at each of at least two locations along its length a respective engagement portion at which the upper surface is raised and at which the lower surface is raised. The lower surface at a first engagement portion at a first one of the two locations has a form which at least in part corresponds to the form in cross section of the outer upper, surface of a profiled rib of a lower profiled metal panel, while the upper surface of the first engagement portion has a from which at least in part corresponds to the form in cross-section of the inner, lower surface of a profiled rib of an upper profiled metal or plastics panel which longitudinally overlaps the lower panel. The lower surface at a second engagement portion at a second one of the two locations has a form which at least in part corresponds to the form in cross-section of the outer, upper surface of a composite rib formed by a side margin of a lower profiled plastics panel laterally overlapping a side margin of the lower metal panel, while the upper surface at the second engagement portion corresponds to the form in cross section of the inner, lower surface of a composite rib formed by a side margin of an upper metal or plastics panel, which longitudinally overlaps the lower plastics panel and a side margin of the upper panel which overlaps the lower metal panel. [0012] The upper panel which longitudinally overlaps the lower metal panel usually will be a metal panel. The upper panel which longitudinally overlaps the lower plastics panel may be either a metal or a plastics panel, depending on where, in a run of plastics panels, the general device is to be used. [0013] A sealing device according to a first form of the present invention (hereinafter called the "primary" device or sealing device) has an elongate body which, relative to one in-use orientation, has upper and lower longitudinal surfaces and laterally outwardly facing longitudinal side surfaces. In side elevation relative to SPCN-966549 5 that orientation, the primary sealing device has an upper surface at a first engagement portion which at least in part corresponds to the form in cross-section of the inner, lower surface of a profiled rib of an upper profiled metal panel. The lower surface at a second engagement portion at a second one of the two locations has a form which at least in part corresponds to the form in cross-section of the outer, upper surface of a composite rib of laterally adjacent, overlapped lower profiled metal and plastics panels, while the upper surface at the second engagement portion corresponds to the form in cross-section of the inner, lower surface of a composite rib of laterally adjacent, overlapping metal and metal, or metal and plastics, panels. [0014] The primary device is used at the overlapped upper end of a lower metal panel adjacent to a composite rib formed between that panel and a laterally adjacent lower plastics panel. Those ends are overlapped by the lower end of laterally adjacent upper panels, with a metal upper panel overlapping the metal lower panel, and either a metal or a plastics upper panel overlapping the lower plastics panel. The form of the composite rib of the upper panels therefore varies in form depending on whether the upper panel which overlaps the lower plastics panel is a metal or a plastics panel. [0015] The primary sealing device may have each of the first and second engagement portions located at a respective end of the device. In that case, the first engagement portion is able to engage between a respective rib of overlapping metal panels that are next inboard from side margins of the panels, while the second engagement portion is able to engage between a respective composite rib formed between laterally adjacent upper, and laterally adjacent lower, metal and plastics panels. The first engagement portion is able to provide a water-tight seal at each of the overlapping inboard ribs of the metal panels in the manner of a sealing device (herein called the "metal panel" device or sealing device denoting that it is for use between laterally adjacent and also overlapping panels all of metal) of patent application AU2009202866. The second engagement portion has respective sections of which a first section nearer to the first engagement portion is configured for engaging and providing a water-tight seal against the side margin of each of the overlapping upper and lower metal panels, with a second section further from the first engagement portion configured for engaging and providing a water-tight seal against the side margin of each of the overlapping upper and lower plastics panels. SPCN-966549 6 [0016] A composite rib between metal and plastics panels may be such that the composite rib has an upper, outer surface determined mainly by the side margin of the plastics panel. The upper, outer surface may be defined substantially completely by the plastics panel. As a consequence, the first section of the second engagement portion can be blocked from engaging the side margin of the lower one of the overlapping upper and lower plastics panels. At a location at which the primary sealing device is to be positioned, the side margin of the lower one of the plastics panels may be cut away to an extent sufficient to enable the second engagement portion to engage and provide a water-tight seal at the side margin of the lower metal panel. In this way, an effective water-tight seal can be provided at and from the composite rib of the lower panels to and at the next inboard rib of the lower metal panel. [0017] In a second form of the invention, there is provided a sealing device (herein the "second" device or sealing device) which, relative to the one in-use orientation, defines at each end of the body and at least one intermediate location along its length of the body, a respective engagement portion at which the upper surface is raised and at which the lower surfaces is raised. Each of the upper and lower surfaces at each of the two end locations has a respective form which at least in part corresponds to the form in cross-section of the inner, lower surface and of the outer, upper surface respectively of composite ribs of longitudinally overlapping profiled metal and plastics panels, and each of the upper and lower surfaces at the at least one intermediate location has a respective form which at least in part corresponds to the form in cross section of the inner, lower surface and outer, upper surface of a profiled rib of longitudinally overlapping profiled plastics panels. [0018] The second device is intended for use at the upper end of a lower plastics panel which forms a respective composite rib with two metal panels, with the upper end overlapped by the lower end of an upper plastics panel. [0019] The second device may have a length which corresponds to the width of a plastics panel with which it is to be used. In that case, the second device has a number of intermediate locations, each with a respective intermediate engagement portion corresponding to the number of ribs of the plastics panels located intermediate of the side margins of the panels. The intermediate engagement portions are located SPCN-966549 7 such that each provides a water-tight seal at each of respective ribs of overlapping plastics panels. [0020] The second device preferably is used in combination with a number of metal panel devices according to patent application AU2009202866. Thus, where roofing comprises at least two series of laterally adjacent panels which overlap at respective ends, and an end to end series of sealing devices can be provided to form a water-tight seal between the overlapping ends. Where upper and lower overlapping panels are metal panels, a sealing device extending across the width of the metal panels preferably is a metal panel device. Where upper and lower overlapping panels are plastics panels, a sealing device extending across the width of the plastics panels preferably is a device according to the second form of the invention. As a consequence, a water-tight seal is able to be provided between overlapping panels across the width of roofing provided by the panels. For such seal, successive sealing devices, whether metal panel devices, second sealing devices, or to a combination of these two device forms, are adapted to abut and provide a seal between adjacent ends. The ends therefore are configured, between their upper and lower surfaces, to enable this, while abutting ends preferably are secured permanently or releasably in abutting relationship by a suitable retainer member. [0021] The second sealing device is suitable for use between end-wise overlapping upper and lower plastics panels. However, the lower end of a plastics panel may overlap the upper end of a metal panel, or the upper end of the plastics panel may be overlapped by the lower end of a metal panel. Thus, overlapping ribs of upper and lower overlapping panels differ from those between overlapping metal panels or overlapping plastics panels. The difference depends on which of overlapping metal and plastics panels comprise the upper panel and the lower panel. [0022] In a third form of the invention, there is provided a sealing device (herein a "third" device or sealing device) which, relative to the one in-use orientation, defines at each end of the body and at least one intermediate location along its length of the body, a respective engagement portion at which the upper surface is raised and at which the lower surfaces is raised. In the third device, each of the upper and lower surfaces at each of the two end locations has a respective form which at least in part corresponds to the form in cross-section of the inner, lower surface and of the outer, SPCN-966549 8 upper surface respectively of composite ribs of longitudinally overlapping profiled metal and plastics panels, and the upper surface at the at least one intermediate location has a form which at least in part corresponds to the form in cross-section of the inner, lower surface of a profiled rib of a profiled plastics panels, while the lower surface at the at least one intermediate location has a form which at least in part corresponds to the form in cross-section of the upper, out surface of a profiled rib of a profiled metal panels. [0023] In a fourth form, there is provided a sealing device (herein a "fourth" device or sealing device) which, relative to the one in-use orientation, defines at each end of the body and at least one intermediate location along its length of the body, a respective engagement portion at which the upper surface is raised and at which the lower surfaces is raised. In the fourth device, each of the upper and lower surfaces at each of the two end locations has a respective form which at least in part corresponds to the form in cross-section of the inner, lower surface and of the outer, upper surface respectively of composite ribs of longitudinally overlapping profiled metal and plastics panels, and each of the upper surface at the at least one intermediate location has a form which at least in part corresponds to the form in cross-section of the inner, lower surface of a profiled rib of profiled metal panels, while the lower surface at the at least one intermediate location has a form which at least in part corresponds to the form in cross-section of the upper, outer surface of a profiled rib of a profiled plastics panels. [0024] As with the second device, the third and fourth devices are suitable for use as part of a sequence including metal panel devices. Again, a third or fourth device can be adapted at each end to abut, and provide a seal, with an end of a respective metal panel seal device. Again, abutting ends preferably are secured, either permanently or releasably, in such end-to-end abutting relationship by a suitable retaining member. [0025] The third device is intended for use at the upper end of a lower metal panel which is overlapped by the lower end of an upper plastics panel. The fourth device is intended for the converse arrangement in which the lower panel is a plastics panel and the upper panel is a metal panel. SPCN-966549 9 [0026] Where any one of the second, third or fourth sealing devices is used in an inline end to end series of sealing devices, the series preferably is positioned substantially parallel to, but a short distance from, the free end edge of the lower one of overlapping panels. The short distance may, for example, be from 50mm to 80mm. This accords with a usual overlap of 70mm to 100mm between the overlapping ends of upper and lower panels installed in long span roofing. However, it also enables a highly preferred arrangement according to the invention, in which primary sealing devices are used in an inline series of devices including at least one second, third or fourth device. [0027] In the preferred arrangement, a respective primary sealing device is positioned in relation to each composite rib between metal and plastics panels. Each primary device is positioned on the free-board section of the metal panel, between the in-line series and the free end edge of the metal panel so as to provide a seal between the composite rib and the next inboard rib of the metal panel. [0028] A need can exist for a variant of the primary device. Thus, according to a fifth form of the invention, there is provided a sealing device (herein called a "fifth" device or sealing device) which has an elongate body which, relative to one in-use orientation, has upper and lower longitudinal surfaces and laterally outwardly facing longitudinal side surfaces. In side elevation relative to that orientation, the fifth sealing device defines at each of at least two locations along its length a respective engagement portion at which the upper surface is raised and at which the lower surfaces is raised. The lower surface at a first engagement portion at a first one of the two locations has a form which at least in part corresponds to the form in cross section of the outer, upper surface of a profiled rib of a lower profiled metal panel, while the upper surface at that first engagement portion has a form which corresponds to the form in cross-section of the inner, lower surface of an upper profiled plastics panel. The lower surface at a second engagement portion at a second one of the two locations has a form which at least in part corresponds to the form in cross-section of the outer, upper surface of a composite rib of longitudinally overlapping upper and lower profiled metal and plastics panels. [0029] The fifth device has a function similar to a primary device. The specific application is in relation to a metal panel which is laterally adjacent and forms a SPCN-966549 10 composite rib with a plastics panel, and which has an upper end overlapped by another plastics panel. [0030] The body of the sealing device of the invention may have a level of resilience by which it is able to deform elastically between overlapping panels and thereby provide a seal with each panel along the length of the body of the sealing device. To enable this, the body of the device may be partly or wholly formed of a resilient material, such as a resilient plastics material, preferably a foam of a synthetic plastics material. Where the resilient material is a foam, it preferably is a closed cell foam, such as of an ethylene propylene diene monomer or of a polyamide. While resilient, the body of the sealing device preferably is sufficiently stiff as to sufficiently resist compression as the upper panel is pressed down onto the sealing device, and thereby provide a positive pressure against each of the panels for effective sealing between the panels. [0031] Subject to the chosen material, the body of the sealing device and its at least one engagement portion may be formed entirely of the one resilient material, such as a foam material. However, it can be beneficial for the sealing device to include along its length a relatively more stiff reinforcing member, such as for stiffening resilient material of the body. The sealing device may, for example have adjacent layers of foam or other resilient material and reinforcing material. Thus, in a first form, one of the side surfaces of the body may be defined by a layer of a resilient material, with the other side surface defined by a reinforcing member. In a second form, the sealing device has three layers, with the side surfaces defined by a respective layer of resilient material secured to an intermediate layer forming the reinforcing member. In a third form, a single layer of resilient material is secured between respective reinforcing members each defining a respective side surface. In each of those forms, the width of the or each layer of foam or other resilient material, between the upper and lower surfaces of the body of the sealing device, exceeds that of the or each reinforcing member to enable the resilient material to be compressed to provide a seal between overlapping panels. [0032] In an alternative form, each of the upper and lower surfaces of the body of the sealing device is defined by a respective layer of foam or other resilient material. SPCN-966549 11 In that form, the body has reinforcing member intermediate of the layers of resilient material, preferably with those layers secured directly to the reinforcing member. [0033] Overlapping roofing panels are secured to a roof frame at locations other than where they overlap using roofing clips. The sealing device of the invention enables a short length of overlap between panels, such as of about 270 to 330mm. As a consequence, the panels can be adequately secured relative to each other at their overlap by a respective roof clip for each panel just beyond that overlap. In that case, the sealing device does not need to provide for securement between the panels at their overlap. Rather, the sealing device may principally or solely provide sealing between the panels. However, despite this, it is preferred that the at least one engagement portion of the body of the sealing device is adapted to strongly engage with each of the overlapping ribs, or at least an inboard rib of a metal panel. To enable this, the engagement portion preferably includes a cleat structure of a relatively rigid material and able to achieve a snap-fit engagement with each of the ribs and thereby assist in securing the overlapping panels together. [0034] The cleat structure may have a form corresponding at least partially to that of the engagement portion. The cleat structure may be incorporated within the engagement portion, or it may be secured against at least one side face of the engagement portion. In one convenient arrangement, the cleat structure has a respective cleat part secured against each side face of the engagement portion. In that arrangement, at least one projection or pin may extend through the engagement portion to engage and to secure the cleat parts in assembly. Alternatively, each cleat part may be securely bonded to a respective side of the engagement portion. [0035] The cleat structure may be made of a rigid engineering plastics material. In the case of a cleat structure having cleat parts secured in assembly by a projection or pin, the projection or pin may be formed integrally with a cleat part. Alternatively, the cleat parts may be secured in assembly by a projection or pin applied through each of the cleat parts. [0036] The cleat parts may be formed of a metal, such as panel steel. If having two cleat parts, those parts may be secured in assembly by any suitable form of projections or pins, such as rivet pins. SPCN-966549 12 [0037] A modified form of cleat structure can be provided at abutting ends of longitudinally in-line sealing devices. While the cleat structure may be similar overall to the forms described above, it preferably is secured in place once the ends are abutting. Also, the cleat structure preferably includes a linking member which secures the cleat structure to each of the abutting ends. [0038] Except as herein specified, the form of construction of the sealing devices of the invention, and of their construction, may be as detailed in patent application AU2009202866, the disclosure of which is hereby incorporated by reference to be read as part of this present specification. Similarly, the cleat structures and retaining pins may be as disclosed in AU2009202866. Brief Description of Drawings [0039] In order that the invention may be understood more readily, reference now is directed to the accompanying drawings, in which: [0040] Figure 1 is an exploded perspective view of upper and lower profiled roofing panels between which sealing devices are provided; [0041] Figures 2 and 3 show a perspective and side elevation, respectively, of a primary sealing device according to the invention; [0042] Figures 4 and 5 are top and bottom plan views, respectively, of the primary device of Figures 2 and 3; [0043] Figure 6 is a perspective view of an in-line series of sealing devices shown in the arrangement of Figure 1; [0044] Figure 7 is a perspective view of a second sealing device according to the present invention; and [0045] Figure 8 is a sectional view on an arrangement as in Figure 1, shown in the course of completion of installation. SPCN-966549 13 Detailed Description [0046] Figure 1 is a perspective view of roofing panels at a stage of their installation as part of roofing for a building. The panels comprise profiled metal panels RM and R'M which typically would form a major part of the roofing cover, and profiled plastics panels Rp and R'p which are provided between panels RM to increase natural lighting within the building. The arrangement shows the upper ends of laterally adjacent lower panels RM and Rp on the upper ends of which a primary sealing device 10 and an end-to-end series 12 of sealing devices are provided. The arrangement also shows the lower ends of laterally, adjacent upper panels R'M and R'p. The upper panels R'M and R'p are shown with their side margins overlapping. However, this is their as installed arrangement, and panel R'M would be installed before positioning panel R'p. At the side of lower plastics panel Rp, there may be a further plastics panel Rp or a metal panel RM. Figure 6, for reasons that will become apparent, asserts a further metal panel RM, in which case, a further primary device will be provided, but not attached on an upright axis through 1800 relative to the device 10 shown in Figure 1. [0047] Each panel RM and R'M shown is of the form available under our registered trade mark SPEED DECK ULTRA. It has at least two longitudinal ribs 14 spaced by pans 16. Also each panel RM and R'M has complementary side margins 18 (of which only one is shown) which interfit to form a composite rib of the form of a rib 14. Each rib 14 and composite rib has re-entrant sloping sides which converge to the top such that the ribs 14 and composite ribs have a mushroom shape in transverse non section. The panels RM and R'M enable concealed fixing to successive supporting purlins by retaining clips, secured on the purlins, engaging within the ribs over internal ledges defined by the re-entrant side walls. [0048] Each panel Rp and R'p may be of fibreglass, such as available under the trade mark AMPELITE, or of a suitable grade of polycarbonate, such as available under the trade mark SOLASAFE. The panels Rp and R'p have substantially the same width and the same number of inboard ribs 20 as panels RM and R'M have inboard ribs 14, but with side margins which also provide full ribs 20. Again, the ribs 20 are spaced by pans 22, while pans 22 are similar to pans 16 in having strengthening profiles. The arrangement of side ribs 20 of panels Rp and R'p is such SPCN-966549 14 that they form a composite rib 24 with a side margin 18 of panel RM and R'M, respectively, by substantially fully covering the margin 18. [0049] The primary device 10 and the series 12 of devices is to provide seals between the overlapping panels. The primary device 10 is of elongate form and comprises a central longitudinal section 30, a resiliently compressible material which is flanked by longitudinal side sections 32 of a stiffer material. The respective materials for each of sections 30 and 32 maybe of a foam plastics material. The section 30 is larger than sections 32 such that it projects beyond substantially the full perimeter of sections 32, to enable section 30 to deform against, and provide a seal at, surfaces against which device 10 is caused to bear. [0050] The device 10 has an elongate body B and an engagement portion or formation F at one end of body B and an engagement portion or formation F' at the other end. The body B has upper and lower surfaces 34 and 36 each defined by sections 30, 32, and side surfaces 38 each defined by a respective section 32. Each of formations F and F' provides a raised part 34a of upper surface 34, and a recessed part 36a of lower surface 36. The surface parts 34a and 36a of formation F corresponds closely to the internal and external form, respectively, of the mushroom shaped ribs 14 of panels RM and R'M in the part of the composite rib 24 formed by margin 18, and to the internal and external form, respectively, of the side rib 20 in the part of the composite rib 24 formed solely by the rib 20 (i.e. in the part of rib 24 not formed by margin 18). [0051] As can be appreciated most clearly from consideration of Figure 1 in conjunction with Figures 2 and 3, formation F is shaped such that it is able to be received down onto a rib 14 of panel RM, with surface 36a conforming closely to, and interfitting with, the external mushroom shape of the rib 14 of panel RM. Similarly, as panel R'M is applied downwardly, its rib 14 is able to be received down over the surface 34a which conforms closely to, and interfitts with, the internal mushroom shape of the rib 14 of panel R'M. With panel R'M fully installed, at least the section 30 of the device 10 is compressed such that formation F provides a water-tight seal between the respective ribs 14 of panels RM and R'M. SPCN-966549 15 [0052] Formation F is positioned on rib 14 of the panel RM so that body B extends to enable the formation F' to be engaged with a composite rib 24 between panels RM and R'M. As also can be appreciated from consideration of Figure 1 in conjunction with Figures 2 and 3, formation F' differs from formation F. The half of formation F' which extends from body B has the form (in reverse) of the half of formation F which extends from the other end of body B. Thus, that half of formation F' has a form suitable for engagement with one side of a rib 14. However, the other half of formation F' is not suitable for that engagement, but simply comprises a tongue suitable for bearing against the top surface at one side of a rib 20 of panel Rp and against the underside surface at one side of a rib 20 of panel R'p. [0053] As indicated above, and evident from Figure 1, the side rib 20 of panel Rp fully covers the side margin 18 of panel RM in forming the composite rib 24. This prevents formation F' from bearing against the outer surface of side margin 18. Also, the configuration of formation F', intended to enable it to bear against, and provide a water-tight seal at margin 18, prevents such a seal being obtainable by bearing against rib 20. As a consequence, an end section of the side rib 20 of the composite rib 24 is cut-away, as shown at 25, to an extent sufficient to expose side margin 18 and enable the formation F' to bear against, and provide a water-tight seal at, margin 18. The cut-away 25 extends longitudinally from the upper end of panel Rp to a position just past the site at which formation F' is to contact composite rib 24. The width of the cut-way 25 is no more than sufficient to enable formation F' to engage under the re-entrant step of side margin 18, as the resilience of the material of which device 10 is formed enables formation F' to compress sufficiently to seal around side rib 20. [0054] An alternative to providing a cut-away 25 would be to configure formation F' for bearing against the side face of rib 20. However, this would not result in a reliable water-tight seal being obtained due to the difficult in having formation F' deform to extend under the side edge of rib 20 so as to bear against the base of side margin 18 of panel RM. [0055] With device 10 positioned in relation to lower panels RM and Rp, it then is possible to install the upper panel R'M and, thereafter the upper panel R'p. The formation F is able to be neatly received, and provide a water-tight seal in rib 14 of SPCN-966549 16 panel R'M. Also, formation F' is able to be neatly received, and provide a water-tight seal, in composite rib 24 formed when panel Rp is installed. The formation F' is able to conform to side margin 18 at one side, and to the underside of rib 20 at the other side, of composite rib 24 without the need for a cut-away in either panels R'M and R'p. [0056] With panels R'M and R'p installed, body B of device 10 is able to compress sufficiently between the respective pan 16 of panels RM and R'M. Thus, a water-tight seal is provided between the installed panels between the overlapping composite ribs 24 and the next inboard overlapping ribs 14 between which device 10 is installed. [0057] The sections 30, 32 of body B are secured together by pins 40 inserted therethrough. The pins 40 are forced through pre-formed holes in sections 30,32, causing the holes to resiliently enlarge as pins 40 are inserted, after which the plastics materials of body B recover to grip each pin between its head 40a and its enlarged leading end 40b. Also, a rigid stiffening member 42,43 is provided at each side of formation F. The members 42,43, such as of stiff plastics material, have a form corresponding to the general form of formation F in side elevation, and enhance the retention of formation F on the rib 14 of panel RM and within the overlapping rib 14 of panel R'M. Pins extending between members 42,43, through sections 30,32, secure the members 42,43 in position. [0058] Stiffening members are not shown on formation F'. However, they can be provided if required, at least on the half of the formation F' adjacent to body B. [0059] With further reference to Figure 1, in combination with Figures 6 and 8, primary device 10 is shown as located between the upper edge of panels RM and Rp and the series 12 of sealing devices. While device 10 provides sealing between the overlapped panels, from composite rib 24 to the next inboard rib 14 of panel RM, series 12 provides sealing across substantially the full lateral width of the overlapped panels. [0060] The series 12 of sealing devices includes a metal panel device 50 provided across and between each pair of overlapped metal panels RM,R'M, and a second sealing device 52 similarly provided for each pair of overlapped plastics panels Rp, R'p. However, roofing can be made up of more than two laterally adjacent panels, including metal panels and at least one plastics panels. Thus, Figure 6 shows a series SPCN-966549 17 12 for use between lower and upper sets of three laterally successive panels. Thus, series 12 as shown in Figure 6 has a second seal 52 between two metal panel sealing devices 50. The designation "metal panel device" denotes a sealing device as in patent application AU 2009202866, while "second" denotes a seal according to the second form of the invention as previously described before reference herein to the drawings. [0061] The metal panel devices 50 and the second devices 52 have a form which generally will be understood from description of primary device 10. This is insofar as devices 50 and 52 are made up of layers of foam material, with each having a body B separating formations. However, there are successive sections of device 50 comprising a respective body B, joined end to end by a respective formation F, while the first and last body B ends at a formation F'. Each formation F of device 50 has a mushroom shape enabling it to be received down onto a respective mushroom shaped inboard rib 14 of a panel RM, and to receive a similar rib 14 of a panel R'M. Each formation F of device 52 has an inverted U-shape, enabling it to be received down into a respective rib 20 of panel Rp, and to receive a similar rib 20 of panel R'p. Each formation F' of each of devices 50 and 52 corresponds to one half of the respective formation F. The arrangement is such that the respective adjacent formations F' of devices 50 and 52 are able to abut, to provide a composite formation of respective parts F'. The composite formation is able to be received down onto a composite rib 24 between adjacent panels RM and Rp, and such that it is able to receive a similar composite rib 24 formed as panels R'M and R'p are installed. The arrangement is such that adjacent formations F' firmly abut so as to resiliently deform and provide a water-tight seal therebetween. [0062] The series 12 of sealing devices 50 and 52 provides a substantially water tight seal across the lateral extent of roofing in which it is installed. However, again, the side rib 20 of panels Rp and R'p, which form the composite rib 24, extends down over and fully covers the side margin 18 of the respective panel RM and R'M. The formation F' of device 50 does not seal fully against the outer side face of the rib 20 and it is prevented from sealing against the side margin 18. As a consequence, a water-tight seal is not achieved at one side of the composite rib 24, potentially enabling water to pass up the formation F' of device 50 and, but for device 10, to pass to and over the upper edge of the panel RM. SPCN-966549 18 [0063] A seal could be achieved with series12 if a portion of the outer margin of side rib 20 of panel Rp was cut-away. However, there are practical difficulties in cutting away a sufficient portion running from the upper panel Rp to beyond the location of device 50. Also, there are difficulties in accurately cutting away a portion spaced from that end and sufficient to enable the formation F' of device 50 to contact side margin 18 of panel RM. In each case, the panel RP would be weakened, and at risk of crack propagation. There is less such difficulty and risk with the cut-away portion required for device 10, particularly as panel Rp is braced adjacent to that cut away by the series 12 of devices 50 and 52. [0064] Rather than provide a cut-away for device 50, a preferred solution is the installation of a device 10 as described above. The device 10 prevents water which leaks across series 12 from passing to and beyond the upper end of the panel RM. Also, while a limited amount of leaked water can accumulate below the device 10, this water is able to leak back past the end of the device 50 when prevailing weather conditions permit. [0065] The formations F in each of seal device 50 are provided with a respective stiffening member 42,43 at each side. The members 42,43 of each formation F are interconnected through the formation F therebetween. The members have a form corresponding to that of the formation F, and they assist in holding the formations F to the required shape for compression against the respective ribs. [0066] The adjacent formations F' also are provided with stiffening members 42a and 43a. These serve the same purpose as numbers 42,43 but also ensure that the adjacent formations F' of device 50,52 are held in abutting relation prior to and after installation of panels R'M and R'p. [0067] Stiffening members are not shown for formations F of sealing device 52. However, inverted U-shaped stiffening members could be provided, if required. [0068] From the description of Figure 1, the form of the devices 10, 50 and 51 can be appreciated. In a variant on device 10, it will be appreciated that the upper surfaces 34a of formations F and F' could be of inverted U-shape (as in device 52) to enable the installation of an upper plastics panel R'p over the lower metal panel RM. Similarly, the upper surfaces of formations F and F' of device 50 could be of inverted SPCN-966549 19 U-shape for the same purpose. Additionally, the upper surfaces of formations F and F' of device 52 could be mushroom shaped, to enable installation of an upper metal panel R'M instead of upper plastics panel R'p. [0069] Figure 8 is a sectional view at right angles to the fall of the roofing panels. The view shows series 12 of sealing device 50 and 52 fully installed over laterally adjacent lower panels RM and Rp. The laterally adjacent upper panels R'M and R'p are shown in position with their lower ends overlapping the upper ends of lower panels RM and Rp, respectively. However, neither of panels R'M and R'p has yet been pressed down to fully engage with device 50 and 52, respectively. It would be usual for panel R'M to be fully installed prior to panel R'p. When panel R'M is fully installed the ledges of the side walls of its ribs 14 will locate under the head of the mushroom shaped formation F of device 50, and also securely engage with mounting clips mounted on purlins so as to be aligned with ribs 14. [0070] The invention described herein is susceptible to variations, modifications and/or additions other than those specifically described and it is to be understood that the invention includes all such variations, modifications and/or additions which fall within the spirit and scope of the present disclosure.
