A façade glazing with a metal frame and an insulating glazing unit inserted into the frame, which unit has at least two glass panes and a spacer and sealing profile extending circumferentially therebetween close to their edges, wherein at least one RFID transponder is attached to the insulating glazing unit as an identification element and wherein the frame engages around the edges of the insulating glazing unit and, at the same time, covers the at least one RFID transponder in the through-vision direction (arrow A) through the glass panes, wherein at least one separate metal coupling element is inserted into the frame adjacent the transponder for coupling out and coupling in HF radiation transmitted via the transponder to the outside of the façade glazing and received from the outside.

Certain example embodiments relate to an insulating glass (IG) unit. A spacer is interposed between first and second substrates. The spacer helps maintain the substrates in substantially parallel spaced apart relation to one another, and helps define a cavity therebetween. First and second exterior surfaces of the spacer face interior surfaces of the first and second substrates, respectively. Third and fourth exterior surface of the spacer face towards and away from the cavity, respectively. A membrane is provided over at least a part of the fourth exterior surface of the spacer. A pin protrudes through holes in the third and fourth exterior surfaces of the spacer, and through the membrane. The pin is formed from an electrically conducting material. A structural seal for the IG unit is provided external to the spacer and at least partially surrounds a portion of the pin that protrudes through the membrane.

An insulating glazing having a pressure equalization body includes a capillary and a membrane, wherein a first pane is mounted on a first pane contact surface of the spacer and a second pane is mounted on a second pane contact surface of the spacer, the first and second panes and the glazing interior surface of the spacer enclose an inner interpane space, the first and second panes and the outer surface of the spacer enclose an outer interpane space, the pressure equalization body is inserted into an opening on the outer surface, the pressure equalization body contains a gas-permeable membrane and a capillary, the inner interpane space is gas-permeably connected to the atmosphere via the capillary and the membrane, and the capillary has, in at least one section, a diameter less than or equal to 1.2 mm.

A spacer with an integrated ribbon cable for insulating glazings includes a main body including two pane contact surfaces, a glazing interior surface, an outer surface, a hollow chamber, and at least one ribbon cable on the outer surface, wherein the ribbon cable is materially bonded to the outer surface.

Described herein are systems, methods, devices, and other techniques for implementing smart windows, smart home systems that include smart windows, and user devices and applications for control thereof. A smart window, or photovoltaic window, may include a photovoltaic configured to generate electrical power from incident light onto the photovoltaic window, store the electrical power, and send the electrical power to an electronics package or various electrical loads including a wireless communication system, sensors, or window functions. The photovoltaic window may communicate with various smart home system devices such as hub devices and user devices, which may include the reception of control data at the photovoltaic window and the transmission of sensor data captured by the window sensors.

A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.

An insulating glazing unit, includes 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, which has in each case an electrically conductive 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 at a corner of the insulating glazing unit.
