A window or door element includes a frame and an insulated glazing unit removably disposed in the frame, the insulated glazing unit including at least one first electrical connection pin and the frame including at least one second electrical connection pin, the at least one first electrical connection pin of the insulated glazing unit being in electrical contact with the at least one second electrical connection pin of the frame when the insulated glazing unit is inserted into the frame.

A glass panel unit includes: a first substrate including a first glass panel; a second substrate including a second glass panel; and a frame-shaped sealing portion that is hermetically bonded to the first substrate and the second substrate. The sealing portion creates an evacuated space between the first substrate and the second substrate. When viewed from a region where the second substrate is positioned with respect to the first substrate, the first substrate includes a part arranged to stick out of an edge of the second substrate. The part includes a mounting portion used to mount the glass panel unit onto a vehicle.

A frame for a façade, a façade element, a window or a door is formed from a number of profiled elements, at which an insulating glazing unit having at least two glass panes held at a distance from one another is retained. An intermediate space under negative pressure is formed between the glass panes. The insulating glazing unit is clampingly retained at the edge thereof between an inner sealing profiled element and an outer sealing profiled element and pressure strips are provided on the exterior of the insulating glazing unit, which pressure strips are fastened to the profiled elements of the frame. A thermal-conductor arrangement is provided on and/or in the inner sealing profiled elements at least in some areas. Due to the thermal-conductor arrangement, heat can be fed to the edge of the insulating glazing unit lying against the inner sealing profiled element in the event of cold outside temperatures.

A glass panel unit includes: a first panel including a glass pane; a second panel including another glass pane; a sealing portion; an exhaust port; and a printed portion. The second panel is arranged to face the first panel. The sealing portion is formed in a frame shape and hermetically bonds respective peripheral edge portions of the first and second panels to create an evacuated, hermetically sealed space between the first panel and the second panel. The exhaust port is provided for one panel selected from the first and second panels. A port sealing member hermetically seals the exhaust port. The printed portion is provided for the other panel selected from the first and second panels. The printed portion is located in an area, facing the exhaust port, of one surface of the other panel. The one surface either faces toward, or faces away from, the hermetically sealed space.

An insulating glazing unit is provided, including: a first glass pane and a second glass pane; an intermediate glass pane; a first spacer and a second spacer; and a holder holding together the first glass pane, the second glass pane, the intermediate glass pane, the first spacer, and the second spacer. In the insulating glazing unit, a thickness of the intermediate glass pane is less than the first glass pane and the second glass pane, too and a composition of the intermediate glass pane is different from the first glass pane the second glass pane.

This disclosure provides connectors for smart windows. A smart window may incorporate an optically switchable pane. In one aspect, a window unit includes an insulated glass unit including an optically switchable pane. A wire assembly may be attached to the edge of the insulated glass unit and may include wires in electrical communication with electrodes of the optically switchable pane. A floating connector may be attached to a distal end of the wire assembly. The floating connector may include a flange and a nose, with two holes in the flange for affixing the floating connector to a first frame. The nose may include a terminal face that present two exposed contacts of opposite polarity. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

A toggle insert for receiving a toggle assembly in a steel curtain wall structure is disclosed. The toggle insert is a self-leveling profile requiring no welding for fastening to steel curtain wall structure and further provides a screw tolerance of up to 1 inch for locating and fastening toggle screws during installation of glazing elements to the steel curtain wail structure. The toggle insert includes a horizontal section having a front portion, an intermediate portion and a bottom portion, wherein the front portion includes a central elongated opening measuring between 21 mm and 25 mm sandwiched on either sides by slotted screw race and a pair of threaded set screws for leveling into the slotted screw race that fixes the toggle insert by way of wedging into the steel curtain wall structure.

Disclosed is a pane unit (10), which comprises a frame structure (12) formed from a plurality of profiles (14), at least two outer panes (16, 16′), and at least one middle pane (18). The panes are each connected or attached to the frame structure (12). The pane unit (10) moreover comprises at least one functional element (20) used for the illumination of the at least one middle pane (18), which functional element (20) is inserted into at least one chamber (24) provided in the profiles (14). The plurality of profiles (14) are coupled with each other by means of at least one connection element (28), wherein the at least one connection element (28) engages with the profiles (14) in such a manner that the pane unit (10) is hermetically sealed.

An insulating glazing unit includes at least one spacer, which is shaped around the periphery to produce a spacer frame and delimits an inner region, a first glass pane, which is arranged on a first pane contact surface of the spacer frame, and a second glass pane, which is arranged on a second pane contact surface of the spacer frame, and the glass panes project beyond the spacer frame and an outer region is formed, which is filled at least in some sections, with a sealing element, wherein at least one RFID transponder is arranged in the outer region or in the outer edge region of the glass panes, and the RFID transponder contains a slot antenna.
