An insulating glazing includes a first pane, a second pane, an inner spacer frame arranged between the panes, which, together with the panes, delimits an inner interpane space, a surrounding outer spacer frame arranged between the panes, which is arranged on the outward facing side of the inner spacer frame, wherein the inner spacer frame consists substantially of a first hollow profile spacer and the outer spacer frame consists substantially of a second hollow profile spacer, the inner spacer frame and the outer spacer frame are in each case connected together to the first pane and the second pane via a primary sealant, an outer interpane space between the outer side of the outer spacer frame and the first pane and the second pane is filled with a secondary sealant.

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 dosage device for extruding a bicomponent or a monocomponent sealant, particularly for an automatic machine for sealing a perimetric edge of an insulating glazing unit constituted by at least two glass sheets and by at least one spacer frame, having a finite width, is arranged proximate to the perimeter at a finite distance from the margin of the glass sheets, includes a first dosage assembly and a separate second dosage assembly for the dosage and feeding of the sealant, which can be activated alternately, in a first feeding step and in a third feeding step, so that one of them provides flow continuity to an extrusion nozzle while the other one is in the reloading step. The first and second dosage assemblies are activatable, in a second swapping step that is intermediate with respect to the first and third feeding steps, simultaneously and jointly, one of them having a flow-rate ramp that passes from the steady-state value to zero and the other one complementarily having a flow-rate ramp that passes from zero to the steady-state value.

A single axis application unit for processing a glass workpiece includes a workpiece supporting table, an applicator movable on a traveler shiftable along a first linear axis and a central suction unit that is activateable to grip the glass workpiece that travels along a second linear axis oriented generally perpendicular to the first linear axis. A central suction unit brake selectively secures the central suction unit both rotationally and translationally. The central suction unit is freely moveable both translationally and rotationally when the central suction unit brake is released. A mid-peripheral suction unit is located at a fixed location remote from the central suction unit and selectively activateable to grip the glass workpiece to hold the glass workpiece in a fixed orientation. A corner suction gripper is movable with the applicator parallel to the first linear axis, and is selectively activateable to grip the glass workpiece.

A window glazing assembly that can convert an existing or already-installed window, or be used to assemble new construction windows as a multi-pane or multi-glazed window unit, is provided herein. In particular, the glazing assembly includes an attachment assembly (e.g., peel-and-stick double-sided adhesive tape) and one or more glazing layers. Some embodiments further include a spacer assembly comprising a plurality of spacer bars that may be individually installed, e.g., one by one, around the perimeter of the window such as, to the window sash, window frame, or glass window pane, itself. The glazing layer(s) can then be secured or adhered to the spacer assembly, for example, around the perimeter thereof. Some embodiments may include additional or intermediate glazing layers, providing additional insulating airspaces and enhanced performance.

A moisture curable hot melt sealant composition that includes a silane-modified polyurethane polymer that is free of isocyanate groups, a first rosin-based tackifying agent, a second tackifying agent different from the first rosin-based tackifying agent, a first ethylene vinyl acetate copolymer, a butene component having a weight average molecular weight from 30,000 g/mole to 700,000 g/mole and being selected from the group consisting of polyisobutylene, polyisobutene, polybutene, and combinations thereof; and filler.

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.

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.

A laminated pane has at least two panes running, for example, parallel to one another, in which case the panes are joined together in an edge area of the laminated pane, at least in sections, with the help of a transparent mass and/or one that becomes transparent after hardening, preferably in form of glue.
