The present invention provides a highly reliable multilayered glass panel and an encapsulating material for achieving the highly reliable multilayered glass panel. The encapsulating material includes lead-free low melting glass particles containing vanadium oxide and tellurium oxide, low thermal expansion filler particles, and glass beads as a solid content. A volume fraction of the glass beads in the solid content is not less than 10% to not more than 35%, and a volume fraction of the lead-free low melting glass particles in the solid content is larger than a volume fraction of the low thermal expansion filler in the solid content.

A building façade element embodied as an insulating glass unit includes at least one first and one second glass pane, at least one glass spacer consisting of glass, which is connected to each glass pane by at least one sealant, at least one other spacer which is gas-tight or comprises a gas-tight layer and is connected to each glass pane by at least one second sealant, and at least one joining region for a glass spacer and another spacer. The at least one glass spacer, the at least one other spacer and the glass panes form a closed inner chamber that does not affect the visual appearance. To this end, the at least one joining region is closed by a third sealant in a gas-tight manner, with the sealant containing butyl and being guided over the joining region.

A spacer for a multi-pane insulating glazing unit includes a spacer body made from a first material with first and second hollow desiccant chambers extending in a longitudinal direction and a longitudinal groove between the first and second chambers open to a first side of the spacer for holding an intermediate pane of the glazing unit, the groove being delimited in a width direction by first and second side walls and having a bottom wall, and the spacer body having a gas barrier on a second side opposite the first side. The first side wall and/or the second side wall and/or the bottom wall of the groove include at least two electrically conductive portions electrically isolated from each other and configured to make electrical contact with at least one electrical contact of the intermediate pane.

There is provided a gas trapping material and vacuum heat insulation equipment where the gas trapping material can be activated in a sealing step of the vacuum heat insulation equipment, and production efficiency can be enhanced by maintaining a high gas trapping characteristic even when a gas is released in a baking step or in a sealing step under an air atmosphere. The gas trapping material contains porous metal oxide and silver particles having an average particle size of 0.5 nm to 100 nm inclusive.

An insulating window unit for a building including adjacent glazed panels linked to each other by at least one translucent connection element having a structural function, wherein each glazed panel is a multiple glazing unit including plural sheets of glass enclosing at least one closed space between the sheets and including at least one translucent seal along a connection edge of same facing the other adjacent glazed panel.

An insulating glazing includes first and second panes, a spacer, a glazing interior, and an outer interpane space. The first pane is attached to a first pane contact surface and a first side surface of the spacer, the second pane is attached to a second pane contact surface and a second side surface of the spacer, the spacer includes a polymeric main body and a reinforcing profile including an inner face, an outer face, and two side surfaces, the inner face of the reinforcing profile is materially joined at least in some sections to the outer surface of the polymeric body and the width of the reinforcing profile is less than or equal to the width of the polymeric body, and no outer seal is introduced into the outer interpane space, and the outer face of the reinforcing profile is an exposed surface of the insulating glazing facing the surroundings.

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.

The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and a 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 30, and the seal. The spacer is placed between the first glass panel and the second glass panel. The spacer contains polyimide having benzoxazole structures.

The present disclosure relates to a building aperture cover (1) such as a window or a door. The building aperture cover comprises a frame arrangement (2) and a vacuum insulated glass unit (3), wherein the vacuum insulated glass unit (3) comprises an evacuated gap (4) placed between a first and a second glass sheet (3a, 3b), and wherein a plurality of support structures (5) are arranged in the evacuated gap (4). The vacuum insulated glass unit (3) is arranged in the frame arrangement (2, 6). The building aperture cover (1) comprises one or more elongated flexible sealing gaskets (21, 22) arranged between an outer major surface (S1, S2) of the vacuum insulated glass unit (3) and a frame part (13a, 13c, 23a, 23c) of the frame arrangement (2, 6). The one or more elongated flexible sealing gaskets (21, 22) is arranged to extend substantially parallel to an edge (7, 50a-50d) of the vacuum insulated glass unit (3). One or more of the one or more elongated flexible sealing gaskets (21, 22) comprises an interior, sealed cavity (21a, 22a) configured to comprise a pressurized fluid.

A dynamic multi-pane insulating assembly and system including methods for dynamically maintaining the thermal resistance value of the assembly and system. The dynamic multi-pane insulating assembly and system includes an interior pane and first and second exterior panes. The first exterior pane and a first side of the interior pane defines an evacuated gap in communication with a vacuum source and a second side of the interior pane and the second exterior pane defines a pressurized gap in communication with the source of pressurized gas.
