An evacuated glazing assembly has first and second spaced-apart, non-metal substrates connected to each other by a seal element to form an evacuable interior space therebetween. The seal element is formed by bonding a metallic bridge element to at least one of the substrates by cold welding to form a first stage seal and forming a second stage seal at least partially in contact with the first stage seal. The seal element is configured to hermetically isolate the interior space from the surrounding environment, and both the first stage seal and the second stage seal contribute to the hermeticity of the seal element.

An assembly includes a plurality of partitions to partition an internal space, surrounded with a pair of glass substrates arranged to face each other and a the peripheral wall having a frame shape and provided between the pair of glass substrates, into an evacuation space and a ventilation space. The plurality of partitions includes a first partition and a second partition, of which lengths are defined in two different directions. An end of the second partition faces a side portion of the first partition with a predetermined gap left between them. A space between the end of the second partition and the side portion of the first partition constitutes an air passage to evacuate the evacuation space through an evacuation port. The second partition includes, at the end thereof, a swollen portion protruding toward the evacuation space at least along the width of the second partition.

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 pre-formed glazing unit for installation in an opening defined in a structure such as a shed, greenhouse or other temporary building comprises a face panel having a periphery enclosing the face panel and a mounting flange for attachment to an inward side of the structure around a peripheral edge of the opening in use, the mounting flange being connected to the periphery of the face panel by a connecting wall. The connecting wall is integrally formed with the face panel and the mounting flange and extends away from the mounting flange to space the face panel from the mounting flange in an outward direction. The face panel and/or a top panel of the connecting wall may be inclined and/or a bottom panel of the connecting wall may include a drip-inducing formation to direct water away from the structure in use. A double-glazed variant is also disclosed.

The invention relates to a roof window comprising a frame and a laminated vacuum insulated glass (laminated VIG) unit fixed in said frame, the laminated VIG unit comprising: a first glass sheet and a second glass sheet, wherein the first and second glass sheets are separated by an evacuated gap, and wherein a plurality of support structures are distributed inside the evacuated gap between the first and second glass sheets, a lamination layer arranged between the first glass sheet and a further sheet, said lamination layer is bonding to an outer major surface of the first glass sheet facing the evacuated gap, wherein the lamination layer comprises at least a first layer and a second layer of a polymer material, wherein, when the roof window is exposed to impacts; the fluctuation in decibel (dB) over a range of 1000 Hz in the interval from 20 Hz to 13000 Hz will not exceed 10 dB.

A fire resistant vacuum insulating glazing assembly includes at least one vacuum insulating glazing unit that has a first glass pane, GP1, which includes an inner pane face and an outer pane face and a second glass pane, GP2, which includes an inner pane face and an outer pane face. A set of discrete pillars is positioned between the first and second glass panes and maintains a distance between the first and the second glass panes. A hermetically bonding seal seals the distance between the first and second glass panes over a perimeter. An internal volume, V, is defined by the first and second glass panes and is closed by the hermetically bonding seal. There is a vacuum of absolute pressure of less than 0.1 mbar and the inner pane faces face the internal volume, V.
