Examples of the present disclosure provide an overhead door panel. The overhead door panel includes a pair of parallel glass panes, a metal frame with parallel lateral stiles oriented perpendicular to the pair of parallel glass panes, a first seal system located at a first lateral stile, and a second seal system located at a second lateral stile, wherein the first seal system and the second seal system engage with at least one glass pane of the pair of parallel glass panes and a lateral stile of the parallel lateral stiles of the metal frame such that the first seal system and the second seal system are between the at least one glass pane and the lateral stile.

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.

Disclosed embodiments include a spacer key configured for insertion within hollow spacer sections, thereby connecting the hollow spacer sections. The spacer key may include a top wall and a bottom wall connected by opposing side walls such that the spacer key has a tubular cross section and longitudinally-extending body. To control how much of the body is inserted into each spacer section, one or more raised areas may be included on the exterior of the spacer key. Protrusions may extend laterally-outward from the spacer key, configured to contact one or more internal surfaces of surrounding spacer sections upon insertion. External surfaces of the spacer key lacking protrusions may include one or more depressed areas. Longitudinally-extending grooves may also be included on the exterior of the spacer key to accommodate various perforations that may protrude from surrounding spacer sections, thereby improving the fit between the spacer key and spacer sections.

An insulating glazing unit, includes at least two glass panes and a circumferential spacer profile between the at least two glass panes near edges of the at least two glass panes, 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, and wherein the at least one RFID transponder is arranged at a corner of the insulating glazing unit, and wherein an end of the at least one RFID transponder pointing toward the nearest corner of the insulating glazing unit is not more than 30 cm from the nearest corner of the insulating glazing unit.
