The present invention relates to a glass, in particular a glass for the joining of glass panes for the production of vacuum insulating glasses at processing temperatures ≦420° C., to the corresponding composite glass, and to the corresponding glass paste. Moreover, the present invention relates to a vacuum insulating glass produced using the glass paste according to the invention, to the production process thereof, and to the use of the inventive glass and/or composite glass, and glass paste. The glass according to the invention is characterized in that it comprises the following components, in units of mol-%: V.sub.2O.sub.5 5-58 mol-%,Te0.sub.2 40-90 mol-%, and at least one oxide selected from ZnO 38-52 mol-%, or Al.sub.2O.sub.3 1-25 mol %, or MoO.sub.3 1-10 mol-%, or WO.sub.3 1-10 mol-%, or a combination thereof.

A spacer for insulated glazing units having at least one polymeric main body with a wall thickness d having a first pane contact surface and a second pane contact surface running parallel thereto, one first glazing interior surface, one second glazing interior surface, one outer surface, one first hollow chamber, and one second hollow chamber. A groove for receiving a pane runs parallel to the first pane contact surface and the second pane contact surface between the first glazing interior surface and the second glazing interior surface. The first hollow chamber adjoins the first glazing interior surface and the second hollow chamber adjoins the second glazing interior surface. The lateral flanks of the groove are formed by the walls of the first hollow chamber and the second hollow chamber, and the wall thickness d′ in the region of the lateral flanks is less than the wall thickness d of the polymeric main body.

A manufacturing method of a glass panel for a glass panel unit includes a melting step, a spreading step, an annealing step, a cutting step, and a spacer disposition step. The spacer disposition step is a step of disposing spacers onto a glass sheet and is performed by a spacer disposition device prior to the cutting step.

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.

The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and a spacer. The second glass panel is placed opposite the first glass panel. The seal with a frame shape hermetically bonds the first glass panel and the second glass panel to each other. The evacuated space is enclosed by the first glass panel, the second glass panel, and the seal. The spacer is placed between the first glass panel and the second glass panel. The spacer includes a stack of two or more films including at least one resin film.

A spacer for insulating glazing units with a polymeric main body composed of a first pane contact surface and a second pane contact surface running parallel thereto, a first glazing interior surface, a second glazing interior surface, an outer surface, a first hollow chamber, and a second hollow chamber, is realized with a groove to accommodate a pane runs parallel to the first pane contact surface and second pane contact surface between the first glazing interior surface and the second glazing interior surface, the first hollow chamber being adjacent the first glazing interior surface and the second hollow chamber being adjacent the second glazing interior surface, where the lateral flanks of the groove are formed by the walls of the first hollow chamber and the second hollow chamber, and a gas-permeable insert is contained in the groove or at least two inserts are mounted at a distance of at least 1 mm from one another.

A spacer for insulating glazing units is presented. The spacer has a polymeric main body with features that include a first pane contact surface, a second pane contact surface, a first glazing interior surface, a second glazing interior surface, an outer surface, a first hollow chamber, and a second hollow chamber. A groove to accommodate a pane is formed between the first glazing interior surface and the second glazing interior surface, with the first hollow chamber being adjacent the first glazing interior surface and the second hollow chamber being adjacent the second glazing interior surface. Lateral flanks of the groove are formed by walls of the first and second hollow chambers.

A pillar mounting method includes an accommodation step, a mounting step, and a displacement step. The accommodation step is a step of accommodating a plurality of pillars in storage with the plurality of pillars being stacked on each other. The mounting step is a step of pushing one pillar of the plurality of pillars accommodated in the storage out of the storage and mounting the one pillar on a substrate including a glass pane. The displacement step is a step of changing a relative location between the substrate and the storage. The mounting step and the displacement step are alternately repeated to mount the plurality of pillars in a predetermined arrangement on the substrate such that the plurality of pillars are apart from each other.

An insulated glass assembly line generally includes a first and second automated lite picker, a washer, a vertical gas filling and wetting station, a robot, and an applicator station.

A vacuum insulated glazing includes first and second spaced apart glass panes having perimeter portions defining a vacuum space between the glass panes. A vacuum valve is positioned at the perimeter portions of the glass panes and includes a valve body extending between the perimeter portions of the glass panes, and having first and second ends and a fluid conduit extending from the first end to the second end of the valve body and in fluid communication with the vacuum space. A one-way valve in the fluid conduit permits fluid flow from the vacuum space, and prevents fluid flow into the vacuum space. A suction fitting is provided for connecting the valve body to a suction device. An end seal between the perimeter portions of the glass panes is provided for hermetically sealing the vacuum space. A valve for a VIG and a method of making a VIG are also disclosed.
