A spacer for insulating glass panes has a profile body configured as a closed hollow profile substantially closed in cross section, the profile body having first and second side walls in parallel spaced apart from each other, an inner wall extending between the first and second side walls, and an outer wall extending from the first to the second side wall spaced apart from the inner wall. The outer wall comprises a first wall section aligned substantially parallel to the inner wall, second and third wall sections arranged on both sides of the first wall section, the latter, in cross section to the axial direction of the body, aligned at an obtuse angle to the first wall section and to the respective adjacent side wall, and connect thereon. The spacer includes an integral, reinforcing element, extending from the first side wall over the outer wall to the second side wall.

This disclosure describes insulated glass units (IGUs) that incorporate electrochromic devices. More specifically, this disclosure focuses on different configurations available for providing an electrical connection to the interior region of an IGU. In many cases, an IGU includes two panes separated by a spacer. The spacer defines an interior region of the IGU and an exterior region of the IGU. Often, the electrochromic device positioned on the pane does not extend past the spacer, and some electrical connection must be provided to supply power from the exterior of the IGU to the electrochromic device on the interior of the IGU. In some embodiments, the spacer includes one or more holes (e.g, channels, mouse holes, other holes, etc.) through which an electrical connection (e.g., wires, busbar leads, etc.) may pass to provide power to the electrochromic device.

A fenestration unit comprising a frame having a center, a sash coupled to the frame, an interior pane coupled to the sash, a spacer coupled to the interior pane, an exterior pane coupled to the sash and the spacer, the exterior pane including an inward-facing surface, and a peripheral shield disposed on the inward-facing surface of the exterior pane such that, when viewed at direct angle, the peripheral shield hides the spacer, the sash, and at least part of the frame.

Methods are provided for producing insulated glazing units. The insulated glazing unit includes a first pane including a first outer edge, a second pane that overlaps the first pane and that includes a second outer edge, an outer edge sealing spacer arrangement that seals and maintains an inter-pane space between the first pane and the second pane, the outer edge sealing spacer arrangement including: a seat that receives the first outer edge and the second outer edge and that extends along the first outer edge and the second outer edge, a shoe that receives the seat, and a coupling between the seat and the shoe configured to maintain the seat within the shoe.

A spacer for insulating glazings includes a polymeric main body including first and second pane contact surfaces, a glazing interior surface, an outer surface and a hollow chamber. The first and second pane contact surfaces run opposite one another and parallel to one another. The glazing interior surface and the outer surface are connected to one another via the first pane contact surface and the second pane contact surface. The hollow chamber is enclosed by the glazing interior surface, the outer surface, the first pane contact surface, and the second pane contact surface. The outer surface has a first angled section adjacent the first pane contact surface and a second angled section adjacent the second pane contact surface. Each of the first and second angled sections assume an angle of 120 to 150 relative to the respective adjacent first pane contact surface and second pane contact surface.

This invention provides a sealing spacer for spacing apart two window panes to form a window assembly. The spacer has an elongated, flexible strip having opposed edge surfaces and opposed side surfaces. The spacer also has a fiber reinforced polymer layer over the elongated, flexible strip. The opposed edge surfaces undulate with crests and troughs. The spacer has an activatable sealant for directly sealingly securing the flexible strip to each of the two window panes. The activatable sealant is on each of the opposed side surfaces of the fiber reinforced polymer. The invention also provides methods for making the spacer and window assembly.

This disclosure provides spacers for smart windows. In one aspect, a window assembly includes a first substantially transparent substrate having an optically switchable device on a surface of the first substrate. The optically switchable device includes electrodes. A first electrode of the electrodes has a length about the length of a side of the optically switchable device. The window assembly further includes a second substantially transparent substrate a metal spacer between the first and the second substrates. The metal spacer has a substantially rectangular cross section, with one side of the metal spacer including a recess configured to accommodate the length of the first electrode such that there is no contact between the first electrode and the metal spacer. A primary seal material bonds the first substrate to the metal spacer and bonds the second substrate to the metal spacer.

An insulating glazed element including at least one insulating glazing unit including at least a first glass sheet and a second glass sheet associated together by an intermediate frame that keeps them a certain distance from each other. The intermediate frame includes at least two horizontal spacers and at least two vertical spacers, which are transparent. The horizontal spacers include at least two compartments which are separate and contiguous.
