A glass panel unit assembly includes a pair of glass substrates arranged to face each other, a peripheral wall, a partition, an air passage, and an evacuation port. The peripheral wall has a frame shape and is provided between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition has a broader width than the peripheral wall.

A dosage device for extruding a monocomponent or a bicomponent polymeric product, particularly for an automatic machine for forming a spacer frame, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the product, which can be activated, in a first feeding step and in a third feeding step, alternately so that one of them provides continuity of flow to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activated, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.

The spacer member being disposed at each of support points set at predetermined intervals on opposing faces of a pair of glass sheets opposing to each other when a gap formed between the pair of glass sheets is maintained under a depressurized state, wherein the spacer member includes: at least one contacting member having a first planar part on one side and a second planar part on the other side coming into contact with the respective opposing faces of the glass sheets, and a projecting piece extending integrally from the contacting member, and on the assumption that an imaginary column that circumscribes the spacer member with its height direction being vertical to the first planar part is provided, the total area of the first planar part or the total area of the second planar part is equal to or smaller than one half of a circular cross section of the column.

A window or door element includes a frame and an insulated glazing unit removably disposed in the frame, the insulated glazing unit including at least one first electrical connection pin and the frame including at least one second electrical connection pin, the at least one first electrical connection pin of the insulated glazing unit being in electrical contact with the at least one second electrical connection pin of the frame when the insulated glazing unit is inserted into the frame.

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. Pre-wired spacers improve fabrication efficiency and seal integrity of insulated glass units. Electrical connection systems include those embedded in the secondary seal of the insulated glass unit.

An insulating glazing unit extends along a plane, P, defined by a longitudinal axis, X, and a vertical axis, Z; having a width, W, measured along the longitudinal axis, X, and a length, L, measured along the vertical axis, Z, and includes a first glass pane that faces outside and has two major surfaces extending along a plane, P. A second glass pane faces inside and has two major surfaces extending along a plane, P. A spacer maintains a distance, D, between the first and second glass panes, creating a space, S. An antenna unit comprises an antenna and is fixed between the first and second glass panes with a fixing portion for fixing the antenna to one of the glass panes and maintaining the antenna at a distance, Da1, from the inner surface of the first glass pane to create a space, SI, through which gas can circulate.

The insulated glass unit (IGU) that replicates a historic glass window includes a single simulated divided light glass pane, a low-e glass layer, and spacer grills disposed therebetween. True divided light glass window panes are scanned to obtain surface characteristic data, subsequently used to design a pane that includes slumped areas corresponding to the unique topological characteristics of antique glass, separated by flat areas. The flat surfaces provide for sealing the IGU with the spacer grills, while the optics of the original historic glass are preserved via the slumped areas. A mold of the designed pane is then 3D printed in furan resin sand, and a glass layer is melted over the mold to create a one-piece pane that includes the antique features. Accurate replication of these windows enables historic building renovation with modern insulated windows with less sealing while retaining the original appearance, providing improvements in longevity and efficiency.

An electrochromic integrated glazing unit (IGU) comprises an electrochromic lite, a glass lite, a spacer, and a sealant. The electrochromic lite can have a first piece of carrier glass, a second piece of carrier glass, and an electrochromic device disposed between them, where the first and second pieces of carrier glass can be offset such that the first piece of carrier glass extends farther than both the second piece of carrier glass and the electrochromic device along a first edge of the electrochromic lite. A sealant can be disposed between the first piece of carrier glass and the glass lite along a first edge of the electrochromic IGU and further disposed between the second piece of carrier glass and the glass lite. An electrochromic laminated glass unit (LGU) with a similar electrochromic lite can contain one or more shear blocks disposed at a first edge of the electrochromic LGU.

A joiner clip for use in a spacer frame assembly and method of assembly are disclosed herein. The joiner clip includes first and second arms coupled to and extending away from a body, the first and second arms comprising mirror images of each other across a first mirror image axis. The first and second arms are housed within a first channel end of a linear spacer frame when assembled. The joiner clip further includes third and fourth arms coupled to and extending away from the body and away from the first and second arms, the third and fourth arms comprising mirror images of each other across the first mirror image axis. The third and fourth arms are housed within an opposite frame end of the linear spacer frame when assembled. When assembled, the body spaces the first channel end from the opposite frame end.
