A door assembly including a first glass pane, a second glass pane, and a spacer positioned between the first glass pane and the second glass pane such that the first pane and the second pane are separated by the spacer. The door assembly also includes an element that is coupled to the first glass pane and the second glass pane and positioned exterior of the spacer. The spacer and the element cooperate to at least partially define a seal passage, and a clear material is disposed in the seal passage to seal the space, the clear material configured to provide structural support to the assembly.

An insulated glass unit is described and includes at least a first glass layer, a second glass layer and a third glass layer disposed therebetween. The third glass layer is separated from the first glass layer and the second glass layer by first and second sealed gap spaces. The third glass layer has a low CTE as compared to the CTE of the first and/or second glass layers. In some instances, the third glass layer has a CTE of less than 70×10.sup.−7/° C. over a temperature range of 0-300° C.

A corner connector for connecting two hollow profile spacers of insulating glazing units, includes a first leg and a second leg, which are connected to one another via a corner region, and a first electrical supply line, wherein the first leg and the second leg enclose an angle α, where 45°<α<120°, the first leg, the second leg, and the corner region are formed in one piece, at least the corner region surrounds the first electrical supply line, and the first electrical supply line protrudes out of the corner region.

The application describes a frame assembly. The frame assembly comprises: first and second glass panels substantially parallel to each other; and an intermediate ballistic panel positioned between the first and second glass panels. A spacer element is positioned between the first and second glass panels and adapted to receive the intermediate ballistic panel. The spacer element comprises a recess adapted to receive the intermediate ballistic panel therein. The recess is larger than the intermediate ballistic panel in at least one dimension by a tolerance value to accommodate thermal expansion of the intermediate ballistic panel.

An insulated glass unit includes a first pane, a second pane, and a third pane between the first and second panes, and a first sealed gap space between the first pane and the third pane and a second sealed gap space between the second pane and the third pane. The third pane comprises first glass sheet having a coefficient of thermal expansion (CTE) over a temperature range 0 to about 300° C. of less than about 70×10.sup.−7/° C.

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.
