A foam spacer applicator may include: a conveyer unit configured to automatically transfer a glass panel; a foam head unit disposed at a predetermined distance from the front side of the conveyer unit, and configured to automatically supply and bond a spacer to the glass panel transferred from the conveyer unit through a combination of an X-axis horizontal operation and a Y-axis elevation operation through an elevation guide plate disposed with a vertical structure; and a magazine unit disposed at a predetermined distance from the rear side of the foam head unit, and configured to inject and apply a sealant to both surfaces of the spacer while adjusting tension of the spacer, and automatically supply the spacer to the foam head unit.

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 method for applying a patch to a spacer discontinuity or other seal breach includes the step of applying pressure to the patch during the application of the patch to cause sealant carried by the patch to be injected into the spacer discontinuity. This step can be performed with or without the application of heat. Pressure is applied to the patch long enough to position the sealant entirely across the gap between the lites such that the sealant wets out against both interior glass surfaces. Pressure is also applied to the patch long enough to inject sealant into openings defining the discontinuity. A sealant is then applied over the entire patch. The structure of the patch and the patched IG unit are provided.

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 glazing includes a first pane having on an inner-side surface a coating and two busbars for contacting the coating, a second pane, a spacer, which extends peripherally around the first and second panes, two pane contact surfaces, a glazing interior surface, and an outer surface, wherein the first and second pane rest, respectively, against a first and a second pane contact surface of the spacer, an interior, which is enclosed between the first and the second pane, an outer interpane space adjacent the outer surface, in which an outer seal is inserted, and an electrical connection element for electrically contacting the coating having an outer and an inner end, whose outer end protrudes from the outer seal. The inner end of the connection element and one busbar are electrically connected and are arranged between the spacer and the first pane outside the interior formed peripherally by the spacer.

A window spacer may include a spacer substrate having two pane contact surfaces, an adhesive surface, and a glazing interior surface. A multilayer barrier film is in contact with the adhesive surface of the spacer substrate. The multilayer barrier film includes at least two first polymeric layers and at least two inorganic layers. The inorganic layers are separated by a second polymeric layer. The second polymeric layer has a thickness lower than 5 m, preferably lower than 4 m, more preferably having a thickness between 1 m and 4 m.

An insulating glazing includes two glass sheets that are spaced apart by an air- or gas-filled cavity, a spacer arranged at periphery of the glass sheets and that keeps the glass sheets spaced apart, the spacer being transparent and placed on one of the sides of the glazing, and a first barrier that is leaktight to water, formed by a structural seal, the material of which is watertight, and a second barrier that is leaktight to gases and to water vapor, the first and second barriers associated to the transparent spacer being made of transparent material, wherein the second barrier that is leaktight to gases and to water vapor and made of transparent material is arranged at an interface between the glass sheets and the transparent spacer on an internal side of the glazing, the structural seal also at the interface being positioned abutted and aligned with the second barrier.

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.

Fire resistant glazing units, processes for the manufacture of such fire resistant glazing units, the use of fire resistant glazing units in construction, and constructions comprising such glazing units. A fire resistant glazing unit may include two panes of glass which are arranged together with a seal to enclose a fire-resistant interlayer. The seal is adapted to breach in the event of a fire causing increased pressure between the panes, releasing pressure before it can build up and cause a pane to break in an unfavourable manner.

A glass panel unit includes: a sealing member arranged between a first panel and a second panel, which are arranged to face each other with a predetermined gap left between themselves, to hermetically bond the first panel and the second panel together; and an internal space sealed hermetically with the first panel, the second panel, and the sealing member. The glass panel unit further includes a spacer arranged in the internal space so as to be in contact with the first panel and the second panel. The spacer includes a plurality of resin layers that are stacked one on top of another in a direction in which the first panel and the second panel face each other. At least any two of the plurality of resin layers have different elastic moduli.
