The present invention relates to a reflective element for solar fields, having a sandwich-type structure, comprising a reflective sheet (1), a reinforcement sheet (2) and a layer of foam (3) arranged between the reflective sheet (1) and the reinforcement sheet (2). The method of manufacturing the reflective element is performed in a press with first and second approximation means, with the following steps: heating the first approximation means to a temperature T1, arranging a reflective sheet on the first approximation means and acquiring the temperature T1, arranging separating means in the periphery of the reflective sheet, arranging a reinforcement sheet in contact with said separating means, heating the second approximation means to a temperature T2 different from T1, moving the approximation means closer to one another, the second approximation means contacting with the reinforcement sheet and acquiring the temperature T2, and providing a foamable material filling the gap between both sheets, subjecting them to pressure, and the foamable material acquiring its final consistency in the form of a substantially rigid layer of foam (3) adhered to both sheets.

1. A manufacturing method of a reflective element in a press system comprising first approximation means and second approximation means, the method comprising the following steps: heating the first approximation means to a temperature T1,arranging a first reflective sheet (1) on said first approximation means, the reflective sheet (1) acquiring said temperature T1,arranging separating means in the periphery of the reflective sheet (1),arranging a reinforcement sheet (2) in contact with said separating means,heating the second approximation means to a temperature T2 different from T1,moving the first and second approximation means closer to one another, such that the second approximation means contact the reinforcement sheet and it acquires temperature T2, andproviding a foamable material such that it completely fills the gap between the first sheet (1) and the reinforcement sheet (2) subjecting them to pressure, the foamable material acquiring its final consistency and forming a substantially rigid layer of foam (3) adhered to both sheets, andextracting the reflective element (1) and leaving it to cool at room temperature once the process of curing the layer of foam (3) is completed. 2. The method according to claim 1, which comprises providing a reflective coating on the exposed face of the first sheet (1) of the reflective element. 3. The method according to claim 1, wherein the temperature difference between T1 and T2 is in the range of 1 to 30° C. 4. The method according to claim 1, wherein the first and/or second approximation means comprise curving means to provide a curvature to the first (1) and/or second (2) sheet. 5. The method according to claim 1, wherein the first sheet (1) is a glass sheet with a reflective coating. 6. A press system for implementing the manufacturing method of a reflective element of claim 1, the press system comprising: first approximation means suitable for supporting a first reflective sheet (1),first heating means for heating the first approximation means to a temperature T1, such that the first reflective sheet (1) also acquires said temperature T1,separating means suitable for being arranged in the periphery of the reflective sheet (1) once the sheet is arranged on the first approximation means, and for contacting with a reinforcement sheet (2),second approximation means,heating means for heating the second approximation means to a temperature T2 different from T1,driving means for moving the first and second approximation means closer to one another to a distance established by the separating means,injection means for providing a foamable material such that it completely fills the gap between the first sheet (1) and the reinforcement sheet (2) subjecting them to pressure, the foamable material acquiring its final consistency and forming a substantially rigid layer of foam (3) adhered to both sheets, andextraction means suitable for extracting the reflective element. 7. Press system for manufacturing a reflective element according to claim 6, characterized in that the first and/or the second approximation means comprise curving means for providing a curvature to the first (1) and/or second (2) sheet.
