<p>A multilayer structure (1) frontally closing a transparent surface in a building and externally fixed to a wall, suitable to provide an effective natural ventilation and lighting, having a removable frame (10) leaning against said transparent surface (2) and supporting a layer sequence comprising, from inside to outside: an internal interspace (3) surmounted by a transparent cover (4), such internal interspace (3) communicating with the internal environment by means of lower (6) and upper (6') openings and with the external environment by means of an upper opening (9) placed above the transparent surface (2); a first layer (5) of insulating material, the internal interspace (3) being defined by the transparent surface (2) of the building and the wall on one side and said insulating material on the other side, said insulating material being covered by high reflecting material on the side facing the internal interspace (3); an external interspace (12); and an external layer (13) provided with two reclosable external openings (14, 15), one in the upper portion and one in the lower portion of the multilayer structure, said external openings (14, 15) being suitable to be closed in a winter state and allowing an air flow within in a summer state for naturally cooling and for draining the inner air.</p> |
