The glass panel unit is a predetermined part separated from a completed assembly obtained by subjecting a temporary assembly to a predetermined process. In the temporary assembly, the inside space (500) enclosed by the first and second glass substrates and the frame is divided into the first space and the second space with the partition and the gas adsorbent is inside the first space. The predetermined process includes: converting the first space into the evacuated space by evacuating the first space through the gas passage, the second space, and the outlet; and changing a shape of the partition to close the gas passage to form the seal enclosing the evacuated space. The predetermined part includes: a first and second glass panels being parts of the first and second glass substrates; the seal; the evacuated space; and the gas adsorbent.

A coated substrate having a coating and a method of forming the same is disclosed, wherein the coating includes a plurality of discrete layers. The coating includes three reflective layers, an alloy layer disposed between two of the reflective layers, and two oxide layers and has a total thickness of 4000 Å or less.

Vacuum insulated glass (VIG) units having ring shaped pillars. The VIG unit comprises two sheets of glass, an edge spacer and multilayer sealants for hermetic sealing of peripheral edge with a high vacuum gap between two sheets of glass. A plurality of pillars is located between two sheets of glass to support vacuum compressive pressure. The ring shaped pillar is made of transparent engineering plastic or glass and can support a compressive strength of 400 MPa or more.

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.

Certain example embodiments of this invention relate to edge sealing techniques for vacuum insulating glass (VIG) units. More particularly, certain example embodiments relate to techniques for providing localized heating to edge seals of units, and/or unitized ovens for accomplishing the same. In certain example embodiments, a unit is pre-heated to one or more intermediate temperatures, localized heating via at least one substantially two-dimensional array of heat sources is provided proximate to the peripheral edges of the unit so as to melt fits placed thereon, and cooled. In certain non-limiting implementations, the pre-heating and/or cooling may be provided in one or more steps. An oven for accomplishing the same may include multiple zones for performing the above-noted steps, each zone optionally including one or more chambers. Accordingly, in certain example embodiments, a temperature gradient proximate to the edges of the unit is created, thereby reducing the chances of breakage and/or at least some de-tempering of the substrates.

Laminated articles and layered articles, for example, low alkali glass laminated articles and layered articles useful for, for example, electrochromic devices are described.

The present disclosure relates to a method of providing a laminated vacuum insulated glass (VIG) unit (1), wherein the method comprises: providing a lamination assembly (10) comprising a vacuum insulated glass (VIG) unit (11) comprising at least two glass sheets (11a, 11b) separated by a plurality of support structures (12) distributed in a gap (13) between the glass sheets (11a, 11b), and a lamination layer (2) arranged between one of the glass sheets (11a, 11b) of the vacuum insulated glass (VIG) unit (11) and a further sheet (3). The further sheet (3) may be subjected to a first heating temperature (T1) by means of a first heating arrangement (9a), and the glass sheet (11a) of the vacuum insulated glass (VIG) unit (11) facing away from the further sheet (3) may be subjected to a second heating temperature (T2) by means of a second heating arrangement (9b), wherein the first heating temperature (T1) is higher than the second heating temperature (T2). The disclosure additionally relates to a system (100) for providing laminated vacuum insulated glass (VIG) units (1), and use of such a system.

Certain example embodiments relate to vacuum insulating glass units having edge seals based on solder alloys that, when reactively reflowed, wet metallic coatings pre-coated on the glass substrates' perimeters, and/or associated methods. The alloys may be based on materials that form a seal at temperatures that will not de-temper glass and/or decompose a laminate, and/or remain hermetic and lack porous structures in their bulks. Example alloys may be based on inter-metallics of Sn and one or more additional materials selected from post-transition metals or metalloids; Zintl anions (e.g., In, Bi, etc.) from Group 13, 14, 15 or 16; and transition metals (e.g., Cu, Ag, Ni, etc.); and excludes Pb. Thin film coatings in certain example embodiments work with the solder material to form robust and durable hermetic interfaces. Because low temperatures are used, certain example embodiments can use compliant and visco-elastic spacer technology based on lamellar structures and/or the like.

A lateral glazing for a transport vehicle, particularly train glazing, the glazing being fixed multiple glazing, with an openable window, the glazing including at least one substrate intermediate face which includes, in a part of the glazing that is situated under said window, on the one hand, a main sheet of glass and, on the other hand, a main sheet of plastic which is situated in contact between the intermediate face and the main sheet of glass without the main sheet of glass and the main sheet of plastic being in contact with the glazing frame structure.
