Description
SPECIFICATION
Cladding Panel
This invention relates to cladding panels such as are used for covering exterior building walls, and more particularly, to horizontally elongate cladding panels for mounting one above another in parallel array on a wall with the top margin of each panel fastened to the wall and the bottom margin of each panel overlapping and interlocked with the top margin of the panel immediately below it.
Interlocking cladding panels are well known and widely employed to provide protective and attractive exterior wall coverings for residences and other buildings. Roll-formed sheet metal panels, in particular, afford very effective protection, are relatively inexpensive to manufacture, and can be durably prepainted or precoated so as to minimize maintenance. They are easy to install, being nailed or otherwise fastened to a wall along only their top margins, and being formed with appropriately configured longitudinal edge portions, they can readily be interlocked in the above-mentioned overlapping relation to secure their bottom margins against displacement under wind loads or other conditions. Commonly, they are designed to simulate the appearance of conventional wooden clapboards or shingles, with major surfaces that slope downwardly and outwardly.
It is frequently desired to provide thermal insulation for a wall in conjunction with the installation of cladding panels. To this end, composite siding panels have heretofore been produced, constituted of sheet metal outer panel members with backing members or layers on their inner surfaces; the metal panel members afford durable protection, while the backing members (which may, for example, be made of a suitable foamed resin or other material) have some measure of insulating effect. Often, however, the backing members are narrower than the metal panel members, to leave clearance for the interlocking panel edges, with the result that uninsulated regions are left adjacent the joints between panels.In other cases, the backing members are coextensive with the metal panel members, but again it is customary to extend the metal around at least one interlocking edge of each of the panels, creating thermally conductive discontinuities in the insulating layer provided by the assembled array of panels. Furthermore, the joints between adjacent panels, are ordinarily not airtight, but are permeable to cold wind; and the provision of metal interlocking edges requires uneconomical consumption of metal.
Alternatively, interlocking metal panels have sometimes been installed over an effectively continuous layer of foamed resin or other insulating panels also mounted on a wall, but this expedient necessitates installation of two components (insulating panels and metal panels) and does not reduce metal consumption. A further problem, encountered with some known types of composite panels designed to provide tight joints, is that as successively higher courses of panels are installed each panel must initially be positioned at some distance above its final elevation, and then lowered into place; thus, at the top of a wall, an overhanging eave or soffit can interfere with installation of the panels.
According to this invention there is provided a horizontally elongate cladding panel for mounting on a wall with like panels one above another in parallel, overlapping array, comprising a panel member made from sheet material ahd having an outwardly and an inwardly facing major surface and a substantially rigid thermally insulating backing member secured to and extending over the entirety of the inwardly-facing surface of said panel member and having parallel longitudinal top and bottom edge portions, said top edge portion having a flat outwardly facing front surface and a convex radiussed edge surface curving inwardly and downwardly from the upper margin of said front surface, and said bottom edge portion including a downwardly extending butt and a downwardly opening recessed pocket formed inwardly of the butt, said pocket being defined between a flat inwardly-facing surface of the butt and a concave radiussed surface curving inwardly and downwardly from the top of the inwardlyfacing butt surface in conformity with the curvature of said convex radiussed edge surface, said pocket being disposed and dimensioned to receive the top edge portion of an immediate subjacent panel in an array as aforesaid with said butt overlapping the front surface of the top edge portion of the subjacent panel and said concave radiussed surface engaging the convex radiussed edge surface of the panel next below thereby to interlock said bottom edge portion with said panel below.
In this composite panel, the panel member (which may be made from metal or plastics) provides a durable protective outer surface while the backing member (e.g. made of a foamed resin, and preferably produced by moulding for assured dimensional stability and uniformity of configuration) provides a layer of insulation which, in an assembled array of the panels, is effectively continuous. Owing to the fact that the interlocking edge surfaces of adjacent panels are surfaces of the insulating backing member, there is direct insulationto-insulation contact between the edges of adjacent panels throughout the array.Moreover, since this contact is between complementary curved surfaces, the joints between courses of panels are virtually air-tight; and if the axes of curvature of the radiussed surfaces are appropriately located, each panel being mounted can be simply rotated into position on the top edge of a previously-mounted lower course without having to be elevated above its final installed position.
In a specific embodiment of the invention, the panel is designed to be fastened to a wall by nails driven through the upper portion of the panel member. Conveniently, nail holes are pre-formed in the panel member at horizontally spaced locations adjacent the top margin thereof. The position of the nail holes is sufficiently close to the top edge of the panel so as to be covered by the butt of the next higher panel, when the panels are mounted in interlocked array on a wall.
Preferably, the top marginal portion of the panel member (in which the nail holes are formed) is offset slightly inwardly with respect to the major outwardly-facing surface of the metal panel member so that deformation resulting from driving of the nails will be localized in this offset portion and will not affect the appearance of the exposed panel surface. The panel member does not have to extend, above the nail holes, all the way to the top margin of the backing member, and although it surrounds the butt of the backing member it does not extend into the pocket at the bottom edge of the backing member; hence there is an advantageous saving of metal as compared to conventional panels of like exposed height but having a metal-to-metal interlock.
The invention will now be described in more detail with reference by way of example to the accompanying drawings in which:
Figure lisa fragmentary front elevational view of a well-mounted array of cladding panels embodying the present invention,
Figure 2 is an enlarged fragmentary perspective view of one of the panels of Figure 1,
Figure 3 is an enlarged sectional side view of two of the panels of Figure 1, showing one panel installed on a wall and a second panel being installed above it;
Figure 4 is a view similar to Figure 3 showing the position of the second panel after installation; and
Figure 5 is a sectional side view of another embodiment of the invention.
Referring to the drawings, horizontally elongate cladding panels are shown which are designed to be mounted one above another on a vertical exterior building wall in overlapping parallel array and, as thus mounted, to simulate the appearance of conventional wooden clapboards. It will be understood that terms indicating directions (horizontal, vertical, upper, lower, top, bottom, etc.) are used herein with reference to a panel oriented in mounted position on a wall, and that the terms "inner" or "inwardly" and "outer" or "outwardly" respectively designate directions toward and away from the wall.
Figures 1 to 4 show panels 10 embodying the invention, each designed to simulate a single clapboard when mounted with other like panels 10 on a wall 11, and each having an exposed height of (for example) 20 cm and a length of up to 3.7 metres (twelve feet). Each of these panels is constituted of an outer roll-formed sheet metal (e.g. aluminium) panel member 12 and a substantially rigid backing member 14 which is self-sustaining in shape. The backing members, made of a suitable thermally insulating foamed resin such as foamed polystyrene, are preferably produced by moulding, for assured uniformity of shape and dimensions.
The backing member 14 of each panel 10 has a planar vertical inner major surface 1 6 which lies flat against the wall 11 when the panel is mounted thereon, and an outer major surface 1 8 which slopes downwardly and outwardly to provide the sloping appearance of a clapboard surface. It will be seen that the backing member is thicker near the bottom than it is near the top, preferably having an average thickness of at least about 2.5 cms (one inch). The panel member 12 has an outwardly-facing major surface 20, which is the exposed outer surface of the panel 1 0, and an inwardly-facing major surface 22 to which the outer surface 1 8 of the backing member is adhered, e.g. by means of a suitable adhesive such as is conventionally used to adhere an insulating layer or backing to a sheet metal panel member in known types of composite panels.The backing member, as shown, extends over the entirety of the inwardly-facing panel member surface 22 in adherent contact therewith and projects above the top margin of the panel member 12.
The backing member 14 has parallel longitudinal top end bottom edge portions respectively designated 24 and 26, each extending for the full horizontal length of the panel, which are shaped to provide a special interlocking engagement between the edges of adjacent (upper and lower) panels. Thus, the top edge portion 24 has a flat, outwardly-facing front surface 28, and a convex radiussed edge surface 30 which curves inwardly and downwardly through an angle of not more than 900 from the top margin of surface 28 to the inner surface 16 of the backing member.The bottom edge portion 26 includes a downwardly extending butt 32 and has a downwardly opening recessed pocket 34 formed inwardly of the butt; this pocket is defined between a flat, inwardly-facing surface 36 of the butt and a concave radiussed surface 38 that curves downwardly and inwardly from the upper extremity of surface 36 through an angle of not more than 900 in conformity with the curvature of the aforementioned convex radiussed edge surface 10, terminating adjacent the inner surface 1 6 of the backing member at a somewhat higher elevation than the bottom of the butt 32. In other words, the radius of curvature of the surface 38 is substantially equal to the radius of curvature of the surface 30, these radii of curvature being the same for all of the panels 10. The pocket 34 of each panel is disposed and dimensioned to receive the top edge portion 24 of an immediately subjacent panel in an array as aforementioned, with the butt 32 overlapping the front surface 28 of the top edge portion of the subjacent panel and with the concave radiussed surface 38 of the pocket engaging the complementary convex radiussed upper edge surface 30 of the next adjacent panel below.
The bottom edge of the panel member 12 is bent inwardly and upwardly to form a channel flange 40 which receives and closely surrounds the bottom of the butt 32 of the panel member.
This channel flange 40 covers the entire outer surface of the butt (which is coplanar with, and a downward extension of, the outer major surface 1 8 of the backing member), the bottom surface of the butt, and the lower portion of the butt inner surface 36, but does not extend upwardly into the pocket 34.The top marginal portion of the panel member 12 is offset inwardly (with respect to the outwardly-facing major part of the surface 20 of the panel member) to constitute a nailing flange 42 pierced at horizontally spaced intervals with slot-shaped nail noles 44, and overlies the lower part of the front surface 28 of the top edge portion 24 of the backing member, but does not extend to the top margin of the surface 28, although the nail holes are located at a level sufficiently close to the top of the panel that they are covered and concealed by the overlapping butt 32 of the next higher panel in an array of the panels mounted on a wall.The described offsetting of the nailing flange prevents deformations, produced when nails are driven therethrough, from being carried over into the exposed part of the surface 20; to accommodate this offsetting, the front surface 28 of the backing member top edge portion 24 may be similarly offset inwardly with respect to the outer major surface 1 8 of the backing member.
As best seen in Figures 3 and 4, in mounting an array of the panels on a wall 11, each panel 10 of one course is positioned with the inner surface
1 6 of the backing member flat against the wall, and fasteners such as nails 46 are driven inwardly through the holes 44 and through the backing member into the wall to secure the panel to the wall adjacent the top edge portion. 24 of the backing member. To mount a panel 1 0' of the next higher course on the wall, the bottom edge portion 26' of the backing member of the panel 10' is fitted over the top edge portion 24 of the backing member of the already mounted panel 10.The pocket 34' of the higher-course panel 10' receives the top edge portion 24 of the lower course panel 10, with the radiussed surfaces 30 of panel 10 and 38' of panel 10' in extended, close, conforming engagement, and with the butt 32' of panel 10' outwardly overlapping the top edge portion 24 of panel 10 to a level below the locations of the nails 46 that hold the panel 10 on the wall, thereby concealing the latter nails. In this way, when the inner surface 1 6' of the backing member of the higher-course panel 10' lies flat against the wall and the panel 10' is in turn nailed ta the wall by nails 46' driven through its nailing flange 42' (Figure 4), the bottom edge portion 26' of the backing member of the higher-course panel 10' is interlocked with the top edge portion 24 of the panel 10 so as to hold the bottom pf panel 10' securely against movement away from the wall.
That is to say, the downwardly projecting bottom rear portion 48' of the backing member 14' of the higher-course panel 10', in the fully installed position shown in Figure 4, is inserted between the radiussed top edge surface 30 of the lower-course panel 10 and the wall, thus locking the bottom of panel 10' against outward movement. The extended contact between the complementary curved surfaces 30 of panel 10 and 38' of panel 10' provides a virtually air-tight insulation-to-insulation joint between the adjacent courses of panels 10 and 10' such that the respective backing members 1 4 and 14' together constitute an effectively continuous insulating layer, with no discontinuity between the courses.As successively higher courses of the panels are installed, one after another, in the manner already described, to cover the wall 11 completely with an array of panels, this continuous insulating layer is extended over the whole wall.
Owing to the described overlap of the nailing flanges and top edge portions of the backing member of each course of panels 10 by the metal-clad butts of the next higher course of panels, only metal surfaces (preferably prepainted) of the installed array of panels are exposed. Nevertheless the amount of unexposed metal is minimized; i.e. because the interlocking portions of the panels are portions of the backing members rather than metal flanges, there is a substantial saving of metal as compared with known panel designs. The overall appearance of the assembled array is that of an array of clapboards with lapped multiplanar surfaces, the apparent thickness of each clapboard being the thickness of the metal-clad butt 32 of each panel.
As a further feature of the invention in the described embodiment, the axes of curvature of the radiussed surfaces 30 and 38 of each panel are so disposed that the panels of one course can be rotated into their installed position on the wall above the already-mounted panels of the next lower course without having to be lifted above the final position. This rotational movement particularly facilitates installation of a top course of panels beneath overhanging structure such as a soffit.Thus, referring to Figure 3, to enable such rotational movement, the axis of curvature of the concave radiussed surface 38' of the panel 10' may be located at the bottom inner edge 52' of butt 32', and the axis of curvature of the convex radiussed surface 30 of the panel 10 may be located on the outer surface of panel member 12 substantially in register with the fully installed position of the butt edge 52'. With the butt edge 52' positioned by the installer so that these axes of curvature substantially coincide, installation of upper panel 10' is effected by rotating it about the coincident axes in the direction represented by arrow 54.
The manufacture of the panels 10 will be readily apparent, from the foregoing description, to those skilled in the art. The backing members 14 are produced as moulded bodies of foamed resin, i.e. with their top and bottom edge configuration formed by moulding, and the panel members 12 are separately produced from metal strip by roll-forming, the panel members being prepainted or otherwise protectively precoated at least on all surfaces which will be exposed in an assembled array of panels. Thereafter, with an adhesive applied between their facing surfaces, the panel members and backing members are fitted together.
A second embodiment of the panel of the invention, so designed that one panel simulates the appearance of two courses of clapboards, is shown at 110 in Figure 5. This panel may be identical in structure to the panels 10 of Figures 1 to 4 except that it has a greater exposed height, for example 40 cm (16 inches) and that the outer major surfaces of the metal panel member 112 and backing member 114 have complementary central horizontal offsets (indicated at 11 5) so as to resemble two overlapping courses of clapboards. An advantage of the Figure 5 panel is that installation is expedited, because only half as many courses of the panels 110 are needed to cover a given height of wall as are required when the panels 10 are used.
