Abstract

A glazing unit includes a first pane and a second pane, which are connected to one another via a thermoplastic intermediate layer, a metal-based functional layer, which is deposited on an internal surface of the first pane facing the thermoplastic intermediate layer, a coating-free marginal region on the internal surface of the first pane, which is free of metal-based functional layer and extends from one side edge of the first pane over at least 1 mm to at most 5 mm on the internal surface, a protective layer, which, in the coating-free marginal region, is disposed directly on the internal surface of the first pane and, in an overlap region directly adjacent to the coating-free marginal region, is disposed on the metal-based functional layer.
