This invention describes an apparatus for assembling triple pane insulating glass units from a plurality of insulating spacer frames having sealant or adhesive applied to opposite sides of said spacer frames.

A vacuum insulating glazing unit has a length equal to or greater than 800 mm and a width equal to or greater than 500 mm. The unit includes first and second float annealed glass panes having thicknesses Z1 and Z2, respectively. The thickness Z2 is equal to or greater than 4 mm and equal to or greater than (λ−15 mm)/5. The thickness ratio Z1/Z2 is equal to or greater than 1.10. The unit also has a set of discrete spacers positioned between the first and second glass panes and forming an array having a pitch (λ) between 10 mm and 40 nm; a hermetically bonding seal sealing the distance between the first and second glass panes over a perimeter; and an internal volume having a vacuum pressure of less than 0.1 mbar.

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.

A door assembly including a first glass pane, a second glass pane, and a spacer positioned between the first glass pane and the second glass pane such that the first pane and the second pane are separated by the spacer. The door assembly also includes an element that is coupled to the first glass pane and the second glass pane and positioned exterior of the spacer. The spacer and the element cooperate to at least partially define a seal passage, and a clear material is disposed in the seal passage to seal the space, the clear material configured to provide structural support to the assembly.

The aim of the invention is to not use, partially or completely, the inner aluminium profile as a spacer in multi-pane doors of refrigerators whilst retaining the required stability and also to replace all other spacers with transparent glass spacer. The invention also relates to methods for the production thereof. The insulating glass elements for the multiple-pane doors with a transparent edge composite for use in shop fittings, refrigerator construction and special cabinet construction, comprise glass spacers (1) between the base disk (4) and the cover disk (4) in the vertical regions of doors and in the upper horizontal region or in both horizontal regions, aluminum or plastic spacers (2), and EVA film sheets (3) between the base disk (4) and the spacers (1, 2) and between the spacers (1, 2) and the cover disk (4), the EVA film sheets (3) are arranged in the four edge regions overlapping the vertical spacers (2) to the horizontal spacers (1). In another embodiment, the EVA film is replaced with ethylene vinyl acetate copolymer granulates, which is heated by means of a metering device and is applied in a liquefied form at the desired positions as thread-shaped strips. The crosslinking between the glass and the ethylene vinyl acetate copolymer occurs in the lamination oven.

An assembly includes: a pair of glass substrates; a peripheral wall disposed between the glass substrates; partitions; an evacuation port; and air passages. The partitions are provided to partition an internal space, surrounded with the glass substrates and the peripheral wall, into an evacuation space and a ventilation space. The evacuation port connects the ventilation space to an external environment. The air passages are used to evacuate the evacuation space through the evacuation port. The air passages include particular air passages arranged in a second direction perpendicular to a first direction, in which the glass substrates face each other, to constitute a ventilation path running through the internal space in the second direction.

A method for manufacturing a glass panel unit includes an adhesive disposing step, a glass composite generation step, an internal space forming step, an evacuation step, and an evacuated space forming step. The adhesive disposing step includes disposing a thermal adhesive on a second panel. The glass composite generation step includes generating a glass composite including a first panel, the second panel, and the thermal adhesive. The internal space forming step includes heating the glass composite to melt the thermal adhesive to form internal spaces (a first space and a second space). The evacuation step includes exhausting gas from the internal space to evacuate the internal space. The evacuated space forming step includes heating and applying force to part of a first portion or a second portion to deform the part to close an evacuation path to form an evacuated space hermetically closed.

A glass panel unit assembly includes: glass substrates; a peripheral wall having a frame shape and disposed between the glass substrates; a partition; an evacuation port; and a plurality of air passages. The partition partitions an internal space into an evacuation space, a ventilation space, and a coupling space. The evacuation port connects the ventilation space to an external environment. The plurality of air passages includes: a first air passage connecting the evacuation space to the coupling space; and a second air passage connecting the coupling space to the ventilation space. The second air passage includes a particular air passage having a larger dimension than any of the first air passage.

A vacuum insulated glass product and the method for making the same, wherein the vacuum insulated glass comprises: a first glass substrate; a second glass substrate disposed facing the first glass substrate; a sealing structure provided between the first glass substrate and the second glass substrate and used for airtight binding of the first glass substrate and the second glass substrate to form a vacuum cavity; and a plurality of supports provided inside the vacuum cavity for bearing pressure from the first glass substrate and the second glass substrate. The sealing structure comprises: metal layers which are fixedly formed on facing surfaces of the first glass substrate and the second glass substrate, and an intermediate solder layer which is disposed between and connects the metal layers. The sealing structure has arc-shaped transition structures at the corner areas of the glass substrates.
