The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and at least one 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 at least one spacer is placed between the first glass panel and the second glass panel. The at least one spacer has a height H1 smaller than a height H2 of the seal between the first glass panel and the second glass panel.

The invention relates to a method of providing vacuum insulating glass (VIG) units each comprising at least a first and a second glass pane and a plurality of support pillars distributed between opposing surfaces of said glass panes to provide a gap (8) between the glass panes. A plurality of pane elements are provided, and individual topographic representations (TOPREP_2a-TOPREP_2n) of each of said plurality of pane elements (2a-2n) are obtained based on input (4) from a measuring arrangement (3), and the topographic representations are stored in a data storage (DS). The stored topographic representations are processed and resulting surface distance characteristic between pairs of panes are estimated. Vacuum insulating glass (VIG) assemblies are thus provided based on estimated resulting surface distance characteristics. The invention additionally relates to a system for providing manufacturing layouts and a manufacturing facility.

A spacer for multipane insulating glazing units includes a polymeric main body having two pane contact surfaces running parallel to one another, a glazing interior surface and, an adhesive bonding surface. The pane contact surfaces, and the adhesive bonding surface are connected directly or via connection surfaces. The spacer also includes an insulation film, which is applied on the adhesive bonding surface.

A glass panel unit manufacturing method includes a bonding step, a pressure reducing step, and a sealing step. The bonding step includes bonding together a first substrate including a wired glass pane and a second substrate including a non-wired glass pane with a first sealant in a frame shape to create an inner space. The pressure reducing step includes producing a reduced pressure in the inner space through an exhaust port that the first substrate has. The sealing step includes irradiating the second sealant with an infrared ray externally incident through the second substrate to seal the exhaust port up with the second sealant that has melted.

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.

Disclosed is a facade element having a first glass unit, in particular insulating glass unit, and at least one second glass unit, in particular insulating glass unit, arranged adjacently thereto, wherein the two glass units are connected to one another via their edges adjoining one another in an abutment region, preferably exclusively with the aid of an, in particular transparent, adhesive connection, wherein the adhesive connection is preferably formed by a two-component silicone material. The invention further relates to a corresponding production method.

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.

The present disclosure relates to a method of providing an edge sealing in the process of providing a vacuum insulated glass (VIG) unit. A first glass sheet (1a) and a second glass sheet (1b) is provided. A glass frit powder material (5) is heated to a softening temperature (T.sub.frit-powder) to soften the glass frit powder material, and the heated, softened glass frit powder material (5) is applied at the first glass sheet (1a) and/or the second glass sheet (1b). The first glass sheet (1a) and the second glass sheet (1b) are paired before or after applying the heated, softened glass frit powder material. The applied glass frit powder material is re-heated by use of at least one heat source (28, 26), the gap between the paired glass sheets is evacuated in a vacuum chamber (22) and the gap between the paired glass sheets is sealed to provide the VIG unit.

A process for obtaining an insulating glazing including first and second glass sheets that are held parallelly spaced apart with a transparent glass spacer adhesively bonded to the periphery of the glass sheets to make a gas-filled interlayer space, includes providing the spacer that is substantially parallelepipedal and including two rough faces opposite one another, and two smooth faces opposite one another, assembling the spacer between the glass sheets so that each rough face of the spacer is positioned close to an edge, and against an inner face of each glass sheet, the interstitial width between the rough faces of the spacer and the inner faces of the glass sheets being less than 0.01 mm, depositing, at the external joint lines between the rough faces and the inner faces, a transparent adhesive, the adhesive moving by capillary action to cover the surface of the rough faces, then curing the adhesive.

A glass unit according to the present invention includes a first glass plate, a second glass plate that is arranged facing the first glass plate with a predetermined interval therebetween and forms an internal space with the first glass plate, a sealing member that seals a gap at peripheral edges of the first glass plate and the second glass plate, and a plurality of spacers arranged between the first glass plate and the second glass plate. The internal space has been depressurized to a vacuum state, or a predetermined gas has been injected into the internal space. The first and second glass plates each have a thickness of 5 mm or less, the pitch of the spacers is 15 mm or more, and the difference between the height of the highest spacer and the height of the lowest spacer is 0.01 mm or less.
