An electrically dynamic window structure may include first and second panes of transparent material and an electrically controllable optically active material positioned between the two panes. A driver can be electrically connected to electrode layers carried by the two panes. The driver may be configured to alternate between a drive phase in which a drive signal is applied to the electrode layers and an idle phase in which the drive signal is not applied to the electrode layers. The electrically controllable optically active material can maintain its transition state during the idle phase. As a result, the power consumption of the structure may be reduced as compared to if the driver continuously delivers the drive signal.

An insulating glazing includes a first pane, a second pane, an inner spacer frame arranged between the panes, which, together with the panes, delimits an inner interpane space, a surrounding outer spacer frame arranged between the panes, which is arranged on the outward facing side of the inner spacer frame, wherein the inner spacer frame consists substantially of a first hollow profile spacer and the outer spacer frame consists substantially of a second hollow profile spacer, the inner spacer frame and the outer spacer frame are in each case connected together to the first pane and the second pane via a primary sealant, an outer interpane space between the outer side of the outer spacer frame and the first pane and the second pane is filled with a secondary sealant.

The invention relates to a roof or skylight window comprising a frame and an insulated glazing unit, where the insulated glazing unit comprises a first glass pane (10) and a second glass pane (20) each having inner surfaces (11, 21) opposing each other, and a side seal (4) arranged between the first glass pane (10) and the second glass pane (20) creating a sealed cavity (40) between the glass panes (10, 20). The first glass pane (10) comprises an edge surface region (14) overlapping the side seal (4) along at least a first part of the side seal (4), wherein the edge surface region (14) comprises an enamel layer (16) comprising pigments reflecting near infrared light.

A spacer for an insulating glazing, includes a main body, which is a main body A including a first pane contact surface, a second pane contact surface, a glazing interior surface, and an outer surface, or which is a main body B including a first pane contact surface, a second pane contact surface, a first glazing interior surface, a second glazing interior surface, a first inner lateral surface, a second inner lateral surface, and an outer surface, wherein the two inner lateral surfaces, together with the two glazing interior surfaces and the outer surface, form a groove for receiving a pane. The spacer has a screen panel made of an opaque material arranged on the glazing interior surface of the main body A or a screen panel arranged on one of the two glazing interior surfaces of the main body B and extending parallel to the two pane contact surfaces.

An insulated glass unit having: an outer lite, an inner lite, and a shock absorbing spacer bar disposed between perimeter portions of the inner and outer lite, forming a cavity, the spacer bar having: an inner housing with a plurality of desiccant ports disposed between an internal desiccant chamber and the cavity; a desiccant encased within the desiccant chamber; a flexible outer housing in which the inner housing is nested; and a perimeter guard disposed on the outer surface of the spacer bar, said perimeter guard being configured to attach the spacer bar to each lite. The spacer bar is configured to be highly crush resistant, thus preventing the either lite from being dislodged during a forced entry attempt. The desiccant ports expose the desiccant to the cavity for humidity maintenance within said cavity. An additional lite and spacer bar may be implemented to form a three lite IGU.

The driver may be configured to alternate between a drive phase in which a drive signal is applied to the electrode layers and an idle phase in which the drive signal is not applied to the electrode layers.
