A description is given of a glazed structural element, in particular in the form of a door, having a reversible glass-pane arrangement (12) which comprises a polygonal, in particular rectangular, first frame (14) and a second frame (18) which can pivot in the first frame (14), about an axis parallel to an edge, in particular about the rectangle centre line (16), out of a first, fixable, sealed position through 180 DEG into a second, fixable sealed position. Furthermore, actuating devices are provided in order to carry out fixing and sealing in the two positions. According to the invention, the first frame (14), with the second frame (18) inserted therein, is a unit which can pivot in a third, fixed frame (13), the first frame (14) being mounted, on a longitudinal edge, on the third frame (13) via hinges (119), such that the actuating fitting (26, 28, 30) [lacuna] for the fixing of the second frame (18). <IMAGE>
