Abstract: A system for closing openings in a building comprises: at least one structural frame having at least two lateral uprights (11a) and two end cross members, coupled to form a perimetral structure that delimits a space, at least one infill element associated to the structural frame at a front thereof, for closing the space delimited by the perimetral structure, at least one longitudinally extending covering element (21b), configured for being mounted on the structural frame at a back thereof, a magnetic-coupling arrangement (24, 28), for constraining in a magnetic way the at least one covering element (21a) in at least one first region of an upright (11a) or a cross member of the structural frame.

Abstract: A curtain-wall system for a building comprises a plurality of prefabricated cells (2), wherein each cell (2) includes: a structural frame (10) with at least two uprights (11) and two end cross members (12), coupled together to form a perimetral structure that delimits an opening (V); one or more infill elements (14-16) associated to the structural frame (10) at a front thereof, for closing the opening (V) delimited by the perimetral structure; and interface sectional elements (20, 21; 70-72) for coupling the one or more infill elements (14-16) to the front of the structural frame (10). The uprights (11) and the cross members (12) of the structural frame (10) are uprights and cross members made of wood, the wooden uprights (11) having at least one first longitudinal groove (22) on a corresponding outer face, and the wooden cross members (12) having at least one second longitudinal groove (23) on a corresponding outer face.

Abstract: A window or door frame for a structural facade, of the type having punctually suspended panes, comprises at least a first pane capable of moving, whereto a gasket is operatively associated, able to pass from a respective operative condition to a respective inoperative condition, and vice versa, as well as an actuating unit, able to be selectively operated to cause passage of said gasket between the respective operative and inoperative conditions.
