The invention relates to a process for manufacturing a vacuum insulated glazing wherein the glazing is prepared by supplying glass panes, pillars and edge metallic seal elements, said edge metallic seal elements are brazed simultaneously together and with a functional layer previously deposited onto the peripheral zone of the glass panes.

The system includes a series of operable louvers mounted on a four-sided frame and connected on each side to the operating mechanism that allows for easy opening and closing of the louvers. Every part of the system that is exposing to the exterior of the building is separated from the interior part of the system by a low heat conductivity material as a thermal barrier. Each operable louver is composing of a four-sided main frame, two panes of glass (inner and outer) and a coupling mechanism on each side that connects to the operating mechanism. The main frame acts as the thermal break as well as a system that absorbs the energy created when an outside object impacts the window from the outside. The system incorporates sealing devices between all moving parts to eliminate water and air infiltration. The operating system allows for easy opening and closing of the window by rotating each louver with the crank mechanism assisted by springs.

An object is to enable sealing of a peripheral portion of a glass panel with less effort and time. A first metal introduction device 5A is moved from one first corner A at which two sides intersect each other of a pair of rectangular glass plates, toward another end of a first side Vab of the two sides, while performing filling with a metal material. Before the metal material filling the first corner A is solidified, a second metal introduction device 5B is moved from the first corner A toward another end of another second side Vad, while performing filling with a metal material. After the first side Vab and the second side Vad are filled with the metal material, both glass plates are rotated by 180 degrees, and the first metal introduction device 5A is moved toward another end of a fourth side Vcd of two sides intersecting each other at a second corner C diagonal to the first corner A, while performing filling with a metal material. Before the metal material filling the second corner C is solidified, the second metal introduction device 5B is moved from the second corner C toward another end of another third side Vbc, while performing filling with a metal material.

The invention relates to a process for manufacturing a vacuum insulated glazing wherein the glazing is assembled in a single stage by supplying glass panes, metallic spacers and corner and frame metallic seal elements which are brazed onto adhesion layers previously deposited onto the edge region areas of the glass panes.

An object of the invention is to provide a multilayer glass which can be manufactured by a simple process. To solve the above problem, the multilayer glass according to the invention includes a first glass substrate, a second glass substrate that faces the first glass substrate at an interval of a predetermined space, and a sealing part that seals a periphery of an internal space defined by the first glass substrate and the second glass substrate. The sealing part is formed with a sealing material containing low melting point glass. The internal space is in a vacuum state. The first glass substrate includes an exhaust port that is provided to be included in a projection part of the sealing part when being projected in a lamination direction of the first glass substrate and the second glass substrate. The exhaust port is blocked by the sealing material (see FIG. 3).

Certain example embodiments relate to vacuum insulating glass units having edge seals formed in connection with 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 seals 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 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.

The present invention discloses a planar glass sealing structure and a manufacturing method thereof, the planar glass sealing structure comprises, in a top-down order: a first glass substrate, an insulating layer, a metal sealing frame and a second glass substrate. The insulating layer is formed as a frame shape, and disposed on a peripheral margin of the first glass substrate; the metal sealing frame is formed by heating to melt a metal solder layer between the first and second glass substrate, and it can keep a fixed gap between the first and second glass substrate, so that an inner space thereof is kept in an excellent sealed condition. The present invention can ensure the sealing structure of two correspondingly assembled glass substrates, so that the inner space thereof is insulated from moisture and oxygen, so as to increase the performance and quality of the device.
