DETAILED DESCRIPTION OF THE DRAWINGS

[0023] With reference to the figures, the radiating panel is generally designated with the reference numeral 10 and comprises the following succession of layers: [0024] at least one supporting layer 11 which is at least thermally insulating, [0025] at least one heating layer 12 which comprises at least one electric heating element 14.

[0026] This electric element 14 comprises preferably of an electrical cable, as illustrated. However, it can be constituted by an element chosen from a cable, a mesh, or a carbon fiber sheet element.

[0027] If the electric element 14 is constituted by an electric heating cable, the heating layer 12 advantageously comprises a studded element 13 with interspaces for laying one or more electrical heating cables.

[0028] The panel 10 also comprises, in succession after the at least one heating layer 12, a finishing layer 15 which is at least thermally conducting.

[0029] In particular, the studded element 13 comprises a shaped sheet element with studs 16 which extends in the opposite direction to the direction of the supporting layer 11 and is constituted by a membrane made of a material chosen preferably from polypropylene and polyethylene.

[0030] FIG. 5 shows the heating layer 12 and how the electric cable is distributed in a coil on the base of the studded element, substantially the base from which the studs 16 extend, and is held in the interspaces by the side walls of those studs 16. The electric cable traces a path with which it is capable of ensuring a substantially uniform distribution of heat on the surface of the successive finishing layer 15. The plastic material of which the studded element 13 is made, which is conventional per se, makes it elastically deformable and the electric cable is therefore easily insertable between the studs 16, which have undercuts that are adapted to ensure the electric cable is kept in place. Such undercuts are defined substantially by a radiusing on the side walls of the studs 16.

[0031] Even if the electric element is constituted by a net or by a carbon fiber sheet element, uniform distribution of heat is still obtained on the surface of the successive finishing layer 15.

[0032] The electric cable, indicated with 14, exits from the perimeter of the panel, in a lower region in the examples shown, where it can be conveniently associated with a connector (a plug, not shown) for connection to an electrical wiring system of the building in which the panel 10 according to the disclosure is installed.

[0033] Even if the electric heating element is constituted by a net or by a carbon fiber sheet, there is conveniently an electric cable, connected electrically thereto, in order to make the connection to the electrical wiring system.

[0034] FIG. 1 shows a first variation of the panel 10 according to the disclosure, which comprises a pair of heating layers 12 and, in succession to each one of these, a respective finishing layer 15 so as to enclose in a sandwich-like fashion the supporting layer 11 between the pair of heating layers 12. Substantially, in this variation, the succession of layers, heating 12 and finishing 15, is repeated symmetrically with respect to the supporting layer 11 which therefore forms the central layer of the panel 10.

[0035] FIGS. 3 and 4 refer to the same first embodiment, while FIG. 2 shows a second embodiment of the panel 10, such that there is a heating layer 12 and a finishing layer 15, the latter being visible once installation is complete.

[0036] In both cases, the supporting layer 11 is constituted preferably by a material chosen at least from among extruded expanded polystyrene, sintered expanded polystyrene, polyisocyanurate, which ensure thermal insulation, thus favoring the passage of heat from the heating layer 12 in the opposite direction, i.e. toward the finishing layer 15.

[0037] The finishing layer 15 is made of a material preferably chosen from ceramic and natural stone, for example marble. As an alternative it can be constituted, for example, by carpet or by a fabric or by a paintable fiber-reinforced cemented covering, optionally of the same color as the walls on which the panel is installed.

[0038] The panel 10 conveniently comprises a layer of glue 17 for bonding the studded element 13 of the heating layer 12 with the supporting layer 11, and an adhesive 18 between the heating layer 12 and the finishing layer 15. In particular, such adhesive 18 is constituted by a thermally conducting cement adhesive, which substantially fills at least partially the gaps present on the studded element 13.

[0039] The studded element 13, or other heating systems (like the net or the carbon fiber sheet) can alternatively be fixed to the supporting layer 11 by chemical adhesion, for example using extruded adhesives, silicone glues, or pressure-sensitive adhesive systems, or by mechanical fixing, for example using screws, staples and/or other, similar fixing means.

[0040] In place of the ceramic material, stone, carpet, etc., the finishing layer 15 can be made with the application of paint or of resin, or the like, on the cement adhesive 18, after optional suitable smoothing with a fiber-reinforced self-leveling compound.

[0041] Alternatively, the coupling of the studded element 13 with the supporting layer 11 can be done using mechanical fixing means, such as screws, inserts, staples, or rivets, of wood or metal.

[0042] The panel 10 also advantageously comprises a programmable thermostat 19 of the digital and optionally also remotely adjustable type.

[0043] FIG. 4 shows, in a cross-sectional view, the panel 10 according to the disclosure associated with a masonry supporting structure 20 using mechanical fixing means. The fixing can be done at points, with inserts or screws 21, and/or with fall-prevention supports 22.

[0044] Alternatively, the panel 10, in the version with heating 12 and finishing 15 layers only on one side of the supporting layer 11, can be installed by floor-laying or wall-mounting.

[0045] The possibility of covering the supporting layer 11 on both sides makes it possible to improve the aesthetic impact and, advantageously, to obtain an irradiation of heat in opposite directions in order to increase, if necessary, the amount of heat emitted by the panel.

[0046] Furthermore, the possibility of using a finishing layer 15 of ceramic or of natural stone or fiber-reinforced plaster allows the end user to personalize the product with the same finish as the floor and/or as the wall covering.

[0047] The finished product, including the finishing layer 15, can be laid directly during installation, or the finishing layer 15 can be applied after installing the product which was sold without such layer.

[0048] The thicknesses can be modulated as a function of the installation needs of the product.

[0049] FIGS. 6 and 7 show a portion of the panel 10, in a possible variation.

[0050] In this variation, the supporting layer 11 has one or more recesses 30, for the accommodation/passage of the electric element 14.

[0051] In particular, the recesses 30 extend over one or more surfaces 31 of the supporting layer 11 which are at right angles to the surface for interfacing with the studded element 13.

[0052] These recesses 30 follow a U-shaped path and are adapted to contain substantially the curves of the electric element 14.

[0053] In this manner, the electric element 14, defined by an electric heating cable, is capable of heating not only the surface corresponding to the heating layer 12, but also the side surfaces.

[0054] As a consequence, the heat is emitted not only from the front, but also from the sides.

[0055] The use of the radiating panel, according to the disclosure, is evident from the foregoing description and explanation and, in particular, it is evident that it can be installed in any part of a building, simply by connecting it to an outlet of the electrical system of that building and mounting it on a wall or laying it in a floor according to the installation requirements.

[0056] In practice it has been found that the disclosure fully achieves the intended aim and objects by providing a radiating panel that can be installed easily on a wall or in a floor, or even on a ceiling, and which can be customized to generate the desired visual impact.

[0057] The disclosure thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.

[0058] In practice the materials employed, provided they are compatible with the specific use, and the contingent dimensions and shapes, may be any according to requirements and to the state of the art.
