The present invention relates to an apparatus for manufacturing vacuum glass. An apparatus for manufacturing vacuum glass, according to an embodiment of the present invention, includes an exhaust finishing frit inserted into an exhaust hole of a plate glass assembly so as to seal the exhaust hole in an exhaust process. In addition, the exhaust finishing frit comprises: a frit body having a body top part on which a cap frit is placed; a depressed portion which is upwardly depressed from the bottom of the frit body; and an exhaust guide part which is formed to penetrate the outer circumferential surface of the frit body. Thus, it is possible to prevent bubbles from being generated in the exhaust finishing frit during a finishing process.

An insulating glazing unit is provided, including: a first glass pane and a second glass pane; an intermediate glass pane; a first spacer and a second spacer; and a holder holding together the first glass pane, the second glass pane, the intermediate glass pane, the first spacer, and the second spacer. In the insulating glazing unit, a thickness of the intermediate glass pane is less than the first glass pane and the second glass pane, too and a composition of the intermediate glass pane is different from the first glass pane the second glass pane.

Insulated assemblies, insulation units including an assembly, and methods of forming the assemblies and units are disclosed. Exemplary assemblies include a first pane of material, a second pane of material, and one or more monolithic insulating layers interposed between the first pane of material and the second pane of material. The insulating layer can exhibit a thermal conductivity less than 26 mW/(K.m).

A method for manufacturing a pillar supply sheet is a method for manufacturing a pillar supply sheet including a plurality of pillars, a carrier sheet, and an adhesion layer between each of the pillars and the carrier sheet, the method including a pillar forming step. The pillar forming step is a step of forming the plurality of pillars by subjecting the base member to an etching process or a laser irradiation process and removing an unnecessary portion from the base member after the process.

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.

Various embodiments provide a method for applying a spacer to a planar substrate, comprising supplying the spacer to be adhered to the planar substrate; defining a first notch, a second notch, and a third notch in the spacer; applying an adhesive to the spacer; translating the spacer in a longitudinal direction; aligning a first end of the spacer with a first corner of the planar substrate; feeding the spacer and the planar substrate between a front carriage and a rear carriage along a longitudinal axis of an unadhered portion of the spacer while pressing the spacer against the planar substrate to adhere a portion of the spacer being pressed by the front carriage to the planar substrate, and rotating, with a six-axis robot, the planar sheet and adhered portion of spacer.

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.

This invention describes an apparatus for assembling triple pane insulating glass units from a plurality of insulating spacer frames having sealant or adhesive applied to opposite sides of said spacer frames.

The aim of the invention is to not use, partially or completely, the inner aluminium profile as a spacer in multi-pane doors of refrigerators whilst retaining the required stability and also to replace all other spacers with transparent glass spacer. The invention also relates to methods for the production thereof. The insulating glass elements for the multiple-pane doors with a transparent edge composite for use in shop fittings, refrigerator construction and special cabinet construction, comprise glass spacers (1) between the base disk (4) and the cover disk (4) in the vertical regions of doors and in the upper horizontal region or in both horizontal regions, aluminum or plastic spacers (2), and EVA film sheets (3) between the base disk (4) and the spacers (1, 2) and between the spacers (1, 2) and the cover disk (4), the EVA film sheets (3) are arranged in the four edge regions overlapping the vertical spacers (2) to the horizontal spacers (1). In another embodiment, the EVA film is replaced with ethylene vinyl acetate copolymer granulates, which is heated by means of a metering device and is applied in a liquefied form at the desired positions as thread-shaped strips. The crosslinking between the glass and the ethylene vinyl acetate copolymer occurs in the lamination oven.

A vacuum glazing includes a vacuum layer formed between a first glazing and a second glazing, a spacer provided in the vacuum layer, a frame provided at edge portions of the first and second glazings, and a sealant interposed between the frame and surfaces of the first and second glazings to perform sealing of the vacuum layer. The insulating performance of the vacuum glazing is improved.
