The subject matter of this invention is a polygonal heat-insulating glass panel with straight edges and a flat surface, in which the two parallel flat glass panes (1) enclosing the inner space of the glass panel are connected to each other, at least on one side, by a transparent, hermetically sealed spacer (2), forming a closed frame with the other sides. The transparent spacer (2) is composed of an adhesive mould incorporating a transparent adhesive body (5) and an adhesive flange (6) applied between an outer edge sealing glass strip (4.1) and an inner edge sealing glass strip (4.2), where the width of the outer edge sealing glass strip (4.1) matches that of the glass panel, while the width of the inner edge sealing glass strip (4.2) closing the inner space of the glass panel matches that of the inner space of the glass panel. The ends of the flat glass panes (1) are chamfered to allow cutting through the adhesive flange (6) in a way that, at the edges of the flat glass panes (1), the sealing lip formed by chamfering touches the sealing surface 13 of the outer edge sealing glass strip (4.1) of the transparent spacer (2) pressed between the flat glass panes (1).

An induction-heating welding method for vacuum insulated glass comprising upper and lower glass substrates is disclosed. Metal layers are prepared in regions to be sealed for the upper and lower glass substrates. A continuous solder is distributed on the metal layer in the lower glass substrate's region to be sealed. The upper and lower glass substrates are superposed. During welding, a high-frequency induction welding head's center moves forward along a centerline of a width of the metal layers; during induction heating of the metal layers in a corner region, a relative position between a movement route of the high-frequency induction welding head's center and the centerline of the width of the metal layers is changed, so that the movement route deviates from the centerline of the width of the metal layers, and thus reducing induction power and avoiding overheating of the metal layers in the corner region.

A window spacer may include a spacer substrate having two pane contact surfaces, an adhesive surface, and a glazing interior surface. A multilayer barrier film is in contact with the adhesive surface of the spacer substrate. The multilayer barrier film includes at least two first polymeric layers and at least two inorganic layers. The inorganic layers are separated by a second polymeric layer. The second polymeric layer has a thickness lower than 5 μm, preferably lower than 4 μm, more preferably having a thickness between 1 μm and 4 μm.

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.

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.

A gas adsorption unit includes a getter, a package encapsulating the getter, and a low-melting member. The low-melting member is heated, and thereby melted, at a temperature lower than a melting point of the package to bond a connector including the low-melting member onto the package. Next, the low-melting member that has melted is cooled and cured. Then, thermal stress resulting from a difference in thermal expansion coefficient between the package and the connector is caused to the package connected to the connector, thereby breaking the package open.

The present disclosure relates to a laminated vacuum insulated glass (VI G) unit (100) comprising a vacuum insulated glass unit (1) comprising first and second glass sheets (2a, 2b) separated by support structures (3) to provide a gap (4) between the glass sheets (2a, 2b), and an edge-sealing (5) enclosing and sealing said gap (4). An evacuation hole (6) extend to the gap (4) and is arranged in said first glass sheet (2a). A recessed portion (8) may enclose the evacuation hole (6), and a sealing system (7) seals the evacuation hole (6), The sealing system may be arranged in said recessed portion. A lamination layer (11) is arranged between a further sheet (12) and the first glass sheet (2a) comprising said evacuation hole (6). A part of said sealing system (7) extends into a hole (13) in the further sheet (12), and an enclosure device (15) comprising one or more walls (16a, 16b) encloses at least a part of said sealing system (7) and extends into said hole (13) in the further sheet (12) and may also extend into said recessed portion (8). A cover (30) may be placed to cover the enclosure device and hole in the further sheet. The present disclosure moreover relate to methods and a building aperture covering such as a window or door.
