Abstract: A composite pane includes a functional element having electrically controllable optical properties, including a stack sequence formed of an outer pane, a first intermediate layer, a second intermediate layer, and an inner pane, wherein the intermediate layers contain at least one thermoplastic polymer film with at least one plasticizer, and a functional element having electrically controllable optical properties is arranged between the first intermediate layer and the second intermediate layer at least in sections, wherein between the first intermediate layer and the functional element as well as between the functional element and the second intermediate layer, at least one barrier film is arranged, which has, at least in sections, an overhang u beyond the functional element.

Abstract: An insulating glazing unit has at least two glass panes and a circumferential spacer profile between them near their edges, for use in a window, a door, or a façade glazing, and which has in each case a frame, in particular a metallic frame, surrounding the edges of the insulating glazing, wherein at least one RFID transponder is attached to the insulating glazing unit as an identification element, wherein the at least one transponder is arranged on an inner surface of one of the glass panes in the spaced region between the spacer profile and the edge of the glass pane.
