The invention relates to a roof or skylight window comprising a frame and an insulated glazing unit, where the insulated glazing unit comprises a first glass pane (10) and a second glass pane (20) each having inner surfaces (11, 21) opposing each other, and a side seal (4) arranged between the first glass pane (10) and the second glass pane (20) creating a sealed cavity (40) between the glass panes (10, 20). The first glass pane (10) comprises an edge surface region (14) overlapping the side seal (4) along at least a first part of the side seal (4), wherein the edge surface region (14) comprises an enamel layer (16) comprising pigments reflecting near infrared light.

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 glass frit according to this application may include a composition of P.sub.2O.sub.5, V.sub.2O.sub.5, TeO.sub.2, CuO, ZnO, and BaO configured to replace a conventional lead glass composition and enable a low temperature calcination. A coefficient of thermal expansion (CTE) of the glass frit may be matched with that of a glass substrate. The composition may not include an inorganic filler or at least reduce a content of an inorganic filler to reduce or prevent separation and breakage and to improve durability. The glass frit may be used as a paste for a vacuum glass assembly.

A vacuum insulating glazing unit comprising a planar area, first and second glass panes, k discrete spacers distributed over the planar area and positioned between the first and second glass panes, wherein k∈ and k>8, and a peripheral bonding seal hermetically sealing the distance between the first and second glass panes defining an internal volume under vacuum, enclosed between the first and second glass panes and bounded by an inner perimeter of the peripheral bonding seal defining the planar area. The inner perimeter has a substantially rectangular geometry with a length, L, a width, W, with L≥W. The discrete spacers are arranged according to the stress field lines of the combination of atmospheric pressure stresses, σp, applied by the atmospheric pressure on the surface of the vacuum insulating glazing, and of thermal stresses, σt, resulting from a temperature difference between exterior and interior environments.

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.

The present invention provides a panel assembly, a refrigerator, and home appliances. The panel assembly of the present invention comprises: a first panel formed of a glass material; a second panel spaced apart from the first panel and formed of a glass material; a plurality of spacers provided between the first panel and the second panel so as to maintain a gap between the first panel and the second panel, and arranged to be spaced apart from each other; a sealing member disposed between the first panel and the second panel for sealing a space between the first panel and the second panel; an exhaust hole provided in at least one of the first panel and the second panel so as to discharge air such that the space between the first panel and the second panel becomes a vacuum insulation space; and a cover member covering the exhaust hole.

A home appliance includes a refrigerator including a panel assembly. The panel assembly includes: a first panel formed of a glass material; a second panel spaced apart from the first panel and formed of a glass material; a plurality of spacers provided between the first panel and the second panel so as to maintain a gap between the first panel and the second panel, and arranged to be spaced apart from each other; a sealing member disposed between the first panel and the second panel for sealing a space between the first panel and the second panel; an exhaust hole provided in at least one of the first panel and the second panel so as to discharge air such that the space between the first panel and the second panel becomes a vacuum insulation space; and a cover member covering the exhaust hole.

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.

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.
