The interior covering includes or preferably is made up of an aluminum sheet, a layer of a glass fabric or a layer of a glass web. The exterior covering includes the succession of a first layer of plastics material, an aluminum sheet, and a second layer of plastics material. The layers of plastics material are bonded to the aluminum sheet directly or via an adhesive. The exterior covering is bonded to the external surface of the core by glue. ## Claims ### Claim 1 A panel for self-supporting ducts, comprising: a core of mineral wool, an external face of the core being covered with an exterior covering and an internal face of the core being covered with an interior covering, respectively, wherein said interior covering includes an aluminium sheet, a layer of a glass fabric, or a layer of a glass web, wherein the exterior covering includes a succession of a first layer of plastics material, the aluminium sheet, and a second layer of plastics material, said first and second layers of plastics material being bonded to the aluminium sheet directly or via an adhesive, said first layer of plastics material being bonded to the external face of the core by a glue, and wherein the second layer of plastics material is an outer layer including anti-UV particles or a UV-protective film, or a surface of the second layer of plastics material is covered with a UV-protective plastic film. ### Claim 2 (depends on 1) The panel according to claim 1, wherein a thickness of the exterior covering is between 0.05 mm and 0.50 mm. ### Claim 3 (depends on 1) The panel according to claim 1, wherein the first layer of plastics material and the second layer of plastics material are made of polyester. ### Claim 4 (depends on 1) The panel according to claim 1, wherein the exterior covering further includes an external layer bonded to the second layer of plastics material, the external layer being UV-protective film. ### Claim 5 (depends on 1) The panel according to claim 1, wherein the exterior covering is glued to the core by a polyurethane PU glue, a low-density polyethylene (LDPE) glue, hotmelt glues, or water-based glues. ### Claim 6 (depends on 1) The panel according to claim 1, wherein the external face of the core further includes a web of glass fibres or synthetic fibres, said web being bonded to the core by a binder crosslinking mineral fibres of said core. ### Claim 7 (depends on 1) The panel according to claim 1, wherein the exterior covering further includes at least two aluminium sheets, each aluminium sheet being bonded directly or via the adhesive, to one of the first and second layers of plastics material. ### Claim 8 (depends on 5) The panel according to claim 5, starting from the external face of the core, further comprising: a web of glass fibres integrated with mineral fibres of the core; a layer of adhesive; the external covering; and an external layer includes the UV-protective film. ### Claim 9 (depends on 1) The panel according to claim 1, wherein an edge of the panel end is configured to be interlocked. ### Claim 10 (depends on 1) The panel according to claim 1, wherein the internal covering and the external covering are extended by a flap partially overlapping the internal covering and the external covering and being sealed by a strip of a same material, when the panel is joined to another module. ### Claim 11 (depends on 1) The panel according to claim 1, wherein the interior covering is extended beyond an edge of the panel and fixed to a surface which defines a connecting profile, the interior covering being an interior face of the duct. ### Claim 12 (depends on 1) The self-supporting duct comprising: the panel according to claim 1. ### Claim 13 (depends on 12) The self-supporting duct according to claim 12, wherein the self-supporting duct is installed outside a building, an exterior layer of the self-supporting duct being exposed to weather. ### Claim 14 A method of using the panels according to claim comprising: manufacturing the self-supporting ducts. ### Claim 15 (depends on 14) The method according to claim 14, wherein at least one of the self-supporting ducts is mounted outside a building, an exterior layer of the self-supporting duct being exposed to weather. ### Claim 16 (depends on 1) The panel according to claim 1, wherein the self-supporting ducts are air-conditioning ducts. ### Claim 17 (depends on 4) The panel according to claim 4, wherein the UV-protective film includes highly ultraviolet-resistant epoxy resins, urethanes, or polyvinyl fluorides. ### Claim 18 (depends on 5) The panel according to claim 5, wherein the exterior covering is glued to the core by the polyurethane PU glue or the low-density polyethylene (LDPE) glue. ### Claim 19 (depends on 7) The panel according to claim 7, wherein the first and second layers of plastics material are made of polyester. ### Claim 20 A panel for self-supporting ducts, comprising: a core of mineral wool, an external face of the core being covered with an exterior covering and an internal face of the core being covered with an interior covering, respectively, wherein said interior covering includes an aluminium sheet, the exterior covering includes a succession of a layer of web of glass fibres, a first layer of plastics material, the aluminium sheet, and a second layer of plastics material, said first and second layers of plastics material being bonded to the aluminium sheet directly or via an adhesive, said layer of web of glass fibres being bonded to the core by a binder crosslinking mineral fibres of said core, and the second layer of plastics material is an outer layer including anti-LTV particles or a UV-protective film, or a surface of the second layer of plastics material is covered with a UV-protective plastic film.
