A description is given of a glazed structural element, such as a door, but in particular a window, having a reversible glass-pane arrangement which comprises a polygonal, in particular rectangular, fixed frame and a movable frame (flush) which can pivot in the fixed frame, about an axis parallel to an edge, out of a first, fixable, sealed position through 180 DEG into a second, fixable, sealed position. The glass-pane arrangement further comprises actuating devices in order to carry out fixing and/or sealing in the two positions. According to the invention, a second movable frame is articulated laterally on the fixed frame by means of a rotary bearing, it being possible to displace said movable frame to a limited extent perpendicularly to the plane of the fixed frame.
