The present invention refers to a Vacuum Insulating Glazing (VIG) able to provide excellent thermal insulation to the transparent components of curtain walling systems in buildings and to cabinets for domestic or commercial refrigerators, and to a process for its manufacture.

1) Hot-melt single component sealant composition, comprising from 70% to 99 weight % of polyisobutylene based on the total weight of the composition. 2) Use as a primary sealant in a manufacturing process of Insulating Glass units.

The present disclosure relates to a swing door system, preferably for use with a chiller device or freezer device, including at least one swing door, a mullion and a sealing element. The at least one swing door includes a transparent pane and the sealing element is arranged between the swing door and the mullion in a closed position of the swing door. The mullion is translucent at least in part.

High-strength vacuum glass is provided. The vacuum glass includes an air-cooled tempered first glass plate; an air-cooled tempered second glass plate that faces the first glass plate via a depressurized layer; and an outer peripheral sealing portion joining an outer peripheral edge portion of the first glass plate and an outer peripheral edge portion of the second glass plate together so as to seal the depressurized layer. The outer peripheral sealing portion contains solder.

An insulated glazing unit forming a door or window opening panel, which is frameless over at least a part of its periphery, and which includes at least two glass panes spaced apart one from another by two, left and right, glass vertical spacers disposed respectively in proximity to the left and right edges of the glass panes, and two, top and bottom, horizontal spacers of a material other than glass, disposed respectively in proximity to the top and bottom edges of the glass panes. The insulated glazing unit also includes, between each face of the horizontal spacers that faces toward the outside of the insulated glazing unit and the edge of the glass panes, a metal profile, at least one end of the bottom metal profile being attached at least to the two glass panes by a structural adhesive.

The present disclosure relates to a vacuum insulated glazing (VIG) unit and the method for producing such. Furthermore, the present disclosure relates to a window comprising a VIG unit enclosed in a frame.

A method of manufacturing a glass sheet assembly for a vacuum insulated glass unit includes applying an edge seal made of a first material to a perimeter of a first surface of a first glass sheet. The edge seal defining a discontinuity. The method also includes disposing a first surface of a second glass sheet on the edge seal such that a gap is defined between the first surface of the first glass sheet and the first surface of the second glass sheet. The method further includes evacuating the gap through the discontinuity and locally heating the edge seal to at least partially seal the discontinuity.

Door for a refrigerated cabinet, formed by multiple glazings that join a spacer frame, peripheral joints, and a reinforcement that makes it possible to do away with frame elements. The door comprises transparent vertical joints that connect the glass sheets of the glazing to transparent spacers.

The disclosure discloses a manufacturing method of tempered vacuum glass, comprising the following steps: (1) manufacturing metalized layers, and performing tempering or thermal enhancement on the glass substrates; (2) placing a metal solder on the metalized layers; (3) superposing the glass substrates to form a tempered glass assembly; (4) heating the tempered glass assembly to 60-230° C.; (5) keeping the tempered glass assembly within the heating temperature range of step (4) in a vacuum chamber, and vacuumizing the vacuum chamber to a preset vacuum degree; and (6) hermetically sealing the metalized layers by adopting a metal brazing process. By adopting the manufacturing method of the disclosure, the stress when the two glass substrates are sealed can be greatly reduced, and the connection strength can be increased; moreover, when gas is exhausted within the temperature range, the exhaust efficiency is high, and the exhaust effect is better, vacuum glass with high vacuum degree can be obtained, and the service life of the vacuum glass is prolonged. The disclosure further discloses a tempered vacuum glass production line based on the above mentioned manufacturing method.

A method for manufacturing a glass panel unit includes a glue arrangement step, an assembly forming step, a first melting step, an evacuation step, and a second melting step. The first melting step includes melting a hot glue, bonding a first and second panel with the glue, and forming an internal space. The first melting step includes a first temperature raising step, a first temperature maintaining step including maintaining the temperature of the assembly at a temperature equal to or higher than a softening point of the hot glue, and a first temperature lowering step, which are performed in this order. The first temperature lowering step includes: an anterior temperature lowering step including lowering the temperature of the assembly; a middle temperature maintaining step including maintaining the temperature of the assembly; and a posterior temperature lowering step including lowering the temperature of the assembly, which are performed in this order.
