Although specific terms are used in the following description for the sake of clarity, these terms are intended to refer only to the particular structure of the embodiments selected for illustration in the drawings, and are not intended to define or limit the scope of the disclosure. In the drawings and the following description below, it is to be understood that like numeric designations refer to components of like function.

[0019] Likewise, cross sections are referred to on normal orthogonal coordinate apparatus having XYZ axis, such that Y axis refers to front-to-back, X axis refers to side-to-side, and Z axis refers to up-and-down.

[0020] Turning now to FIGS. 1A-1B, illustrating in FIG. 1A, an isometric schematic of an embodiment of the cladding panel with enlarged section A illustrated in FIG. 1B. As illustrated, provided herein is cladding panel 10 having apical plane 150 and a basal plane 150, cladding panel 10 comprising: stone layer 100 having a rough external (away from the rubber layer 110) side and a smooth internal side; and recycled rubber layer 110 adhesively (see e.g., glue layer 101 and mechanically coupled to the smooth internal side of stone layer 100, wherein cladding panel 10 is configured to be slidably coupled to an apical bracket 151 (see e.g., FIG. 1B), apical bracket 151 being mechanically coupled to the external side 501 of weight bearing wall 500. The term rough side as used herein means the external layer having a roughness in the range of about 2 mm root mean square (rms) to about 10 mm rms, while the term smooth side, in reference to both the stone layer and the smooth side of rubber layer 110, means having roughness of no more than about 1.5 mm rms.

[0021] As shown in FIG. 1B, apical bracket 151 having L shape is configured to couple to the external side 501 of load bearing wall 500. Fixing means 140, (not shown) physically couple recycled rubber layer 110 to natural stone layer 100, such that the recycled rubber layer 110 and (natural) stone layer 110 are mechanically coupled using no less than four mechanical coupling means for every 0.09 m.sup.2. In other words, regardless of the size of cladding panel 10, a grid of 30 cm.30 cm. can be created in an embodiment whereby mechanical coupling means (e.g., a screw, or an anchor) 140, is inserted mechanically, coupling (natural) stone layer 100 to recycled rubber layer 110, through adhesive layer 101. Mechanical coupling means, as used herein, is a broad term referring in an embodiment to its ordinary dictionary definition and also refers to nails, screws, detents, bosses, anchors, etc. In an embodiment, the mechanical coupling means can be, for example, a galvanized screw, a stainless-steel screw, toggle bolt screw, snap bolt screw or a coupling means combination comprising the foregoing. Furthermore, cladding as used herein is a broad term and includes its ordinary dictionary definition to construct wall assemblies on buildings and/or rooves. Other shapes and materials can be used as well.

[0022] As indicated, rubber layer 110 is a recycled rubber layer having properties unique to its use in cladding panel 10. Accordingly, and in an embodiment, the recycled rubber layer 110 used in the cladding panels provided herein, and mechanically coupled to (natural) stone layer 100 can be fabricated to have a smooth side configured to abut the smooth internal side of (natural) stone layer 100. When mechanically coupled, recycled rubber layer 110 can be configured a bond test of no less than 0.1 KN. The test is conducted according to the bond testing method, whereby a test piece is made by applying an adhesive and a mechanical coupling means, to the central part of a 7 cm7 cm bond testing piece formed of the stone layer, and bonding thereto an attachment (4 cm4 cm in section) for tensile test. This test piece is set in a bond tester and pulled in the direction normal to the surface at 23 C. environment, and the maximum tensile load (Newton) at break is read while observing the condition of break. The read value is divided by the area (16 cm.sup.2) and the quotient is expressed as bond strength (N). The above test is conducted on a plurality (4) test pieces for each specimen and the mean value is determined and reported.

[0023] Furthermore, the smooth side of the recycled rubber layer is configured to abut the smooth side of the stone layer, through the adhesive and still maintain at least one of a static and dynamic (in other words, static and/or dynamic) friction coefficient between rubber layer 110 and (natural) stone layer 100, of between 0.05 and about 2.0. The density of recycled rubber layer 110 can be configured to be between about 50 Kg/m.sup.3 and about 3000 Kg/m.sup.3, and will depend on the environmental conditions and the desired insulation. In other words, density may increase for increased acoustic insulation and decreased for thermal insulation.

[0024] In addition, the compression strength (in other words, the maximum compressive load the cladding panel can bear prior to failure, divided by its cross sectional area) of the recycled rubber layer used in the cladding panels described herein, can be fabricated to be between about 0.5 MPA and about 100 MPA. The compression strength is a factor in certain embodiment that will affect the height at which the cladding panel can be positioned, where wind loads may require compression of the panel due to regulation pertaining to the use of stones as an external faade materials. This may be exacerbated on earthquake-prone regions.

[0025] A choice of source rubber for the recycled rubber layer can be configured to yield a targeted thermal conductivity, which would affect the efficacy of the cladding panel in its use as a thermal insulator. Accordingly and in an embodiment, the thermal conductivity of the recycled rubber s between about 0.02 W/Mk and about 2.2 W/Mk.

[0026] Turning now to FIGS. 2A, 2B, illustrating, with FIGS. 3A, 3B, the assembly of cladding panel 10 on wall 500, with external wall side 501. As illustrated in FIG. 2A (and corresponding apical bracket 150.sub.A, FIG. 3A) L-shaped bracket 150A is mechanically coupled to wall 500 external side 501 via mechanical coupling means 141j, in this case, cement board screw anchor, although others may be used depending on the cladding panel weight and wall 500 construction material e.g. Although the term L-shaped is used to describe the shape of the apical and/or basal bracket(s), with the vertical portion 160 (see e.g., FIG. 3A of bracket 150.sub.A, intersecting the horizontal portion 161 of the bracket, there is not requirement that the bracket(s) be exactly the shape of an L. For example, sharp corners are not required, nor a perpendicular orientation between the vertical leg 160 and the horizontal leg 161. Accordingly bracket 150.sub.A, is coupled to wall 500 external face 501 through vertical leg 160, using mechanical coupling means 141j. As illustrated, bracket(s) 150.sub.A, and/or 150.sub.B, both define distal lip 162 disposed at the distal end of horizontal leg 161 of bracket(s) 150.sub.A, and/or 150.sub.B. Distal lip 162 is configured to engage shelf 105 (see e.g., FIGS. 1B, 2A, 2B) defined in stone layer 100, when panel 10 is slidably coupled to bracket bracket(s) 150.sub.A, and/or 150.sub.B. In an embodiment, the term slidably coupled refers to elements (e.g., distal lip 162 and the shelf 105), which are coupled in a way that permits one element (e.g., shelf 105) to slide or translate with respect to another element (e.g., distal lip 162). In addition, at distance Li rail 163 is defined, which protrude basally from horizontal leg 161, and configured to engage a complimentary channel (not shown) defined on the apical facet of cladding panel 10, in recycled rubber layer 110. As illustrated in FIG. 3A, rail 163 can be disposed equidistance between distal lip 162 and vertical leg 160.

[0027] Turning now to FIGS. 1B, 2B, and 3B, illustrating bracket 150.sub.B, defining a plurality of rails 163, 164, protruding basally from horizontal leg 161, and are configured to engage complimentary channels (not shown), one in (natural) stone layer 100 and another in recycled rubber layer 110, upon sliding of cladding panel 10 into bracket 150.sub.B. The protrusion of rails 163, 164 is not necessarily the same and rail 164 may be configured to protrude less end engage a shallower channel defined in (natural) stone layer 100. This may be advantageous in circumstances where the natural stone layer 100 is made of a relatively weaker stone.

[0028] Also shown in FIGS. 2A, 2B, is insulation foam 145 which can optionally be installed and abut recycled rubber layer 110, as well as spacer 146 separating insulating foam panels 145. Cladding panel(s) can be configured to have space 155, allowing for example, for drainage of and condensed moisture trapped between insulation foam panel(s) 145, and recycled rubber layer 110 of cladding panel 10.

[0029] In an embodiment, cladding panel 10 can further be configured to be slidably coupled to a second, basal bracket 152 (see e.g., FIG. 1A), basal bracket 152 being mechanically coupled to external side 501 of a weight bearing wall 500 and be identical to apical bracket 150, or different (in other words, 150.sub.A, or 150.sub.B). When basal bracket 152 is implemented, cladding panel 10 is fabricated with the complimentary channels and basal distal lip (see e.g., 105, FIG. 1A), to allow for cladding panel 10 to slidably couple to the apical and basal brackets.
