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: a pair of glass substrates arranged to face each other; a peripheral wall; a partition; an air passage; and an evacuation port. The peripheral wall has a frame shape and is disposed between the pair of glass substrates. The partition partitions an internal space, surrounded with the pair of glass substrates and the peripheral wall, into a first space and a second space. The air passage connects the first space and the second space together. The evacuation port connects the second space to an external environment. The partition is lower in height than the peripheral wall.

Certain example embodiments relate to the use of a ceramic frit that dissolves an already-applied thin film coating (disposed via a physical vapor deposition (PVD) process such as sputtering, or other suitable process). In certain example embodiments, the ceramic frit is aggressive in chemically removing the coating on which it is disposed, e.g., when exposed to high temperatures. The frit advantageously fuses well with the glass, provides aesthetically desired colorations, and/or enables components (e.g., insulated glass (IG) unit spacers) to be reliably mounted thereon, in certain example embodiments. Associated coated articles, IG units, methods, etc., are also contemplated herein.

A door assembly includes a doorframe, an insulated glazing unit (IGU), door skins, and a gas passageway. The IGU includes a substantially sealed IGU cavity and a hole communicating with the IGU cavity. The door skins are secured to opposite sides of the doorframe and have openings between which the IGU is provided. The gas passageway provides gas communication between the IGU cavity and the atmosphere outside of the door assembly. The gas passageway contains a gas passage conduit that includes a first end communicating with the IGU cavity through the hole and a second end communicating with atmosphere outside of the door assembly. The gas passageway may contain a gas passage conduit having a first end communicating with the IGU cavity through the first hole and a second end communicating with an air pocket, and a channel connects the air pocket with atmosphere outside of the door assembly.

A vacuum insulating glazing unit includes a first glass pane having a thickness Z1, and a second glass pane made of prestressed glass having a thickness, Z2, where Z1 is greater than Z2 (Z1>Z2) The glazing unit also includes a set of discrete spacers positioned between the first and second glass panes and a hermetically bonding seal sealing the distance between the first and second glass panes over a perimeter. A vacuum of pressure less than 0.1 mbar is created in an internal volume V. A thickness ratio, Z1/Z2, of the thickness of the first glass pane, Z1, to the thickness of the second glass pane, Z2, is equal to or greater than 1.30 (Z1/Z2≥1.30).

A system for producing multiple-pane insulating glazing units can include a conveyor and a plurality of laterally spaced-apart processing stations that are movable transversely relative to the longitudinally extending conveyor line. Each processing station may assemble glazing panes and a glazing spacer into a partially fabricated glazing unit, deliver insulative gas to a between-pane space between the glazing panes, and press the partially fabricated glazing unit together to seal the insulative gas in the between-pane space and form the multiple-pane insulating glazing unit. In some examples, each processing station moves to an alignment position with the conveyor to load glazing panes and a glazing spacer and then performs individual fabrication steps while offset from the conveyor. During this time, a different processing station can be aligned with the conveyor to unload a fabricated multiple-pane insulating glazing units and/or load unassembled glazing panes and a glazing spacer.

A door assembly includes a doorframe, an insulated glazing unit (IGU), door skins, and a gas passageway. The IGU includes a substantially sealed IGU cavity and a hole communicating with the IGU cavity. The door skins are secured to opposite sides of the doorframe and have openings between which the IGU is provided. The gas passageway provides gas communication between the IGU cavity and the atmosphere outside of the door assembly. The gas passageway contains a gas passage conduit that includes a first end communicating with the IGU cavity through the hole and a second end communicating with atmosphere outside of the door assembly. The gas passageway may contain a gas passage conduit having a first end communicating with the IGU cavity through the first hole and a second end communicating with an air pocket, and a channel connects the air pocket with atmosphere outside of the door assembly.

A compressible pillar for the preparation of a vacuum insulated glazing (VIG) unit, having a longitudinal extent in the pre-compressed state and including a deformable part having an open structure, which open structure will at least partially collapse when the pillar is subject to a compression force acting in the longitudinal direction of the pillar, the compression force being of at least one value selected within the range of 60 N to 320 N, the pillar will exhibit a partly irreversible deformation causing a reduction in the longitudinal extent of the pillar when the pillar is subjected to the compression force, so that when the compression force is fully released the pillar will exhibit an expansion in the longitudinal direction of the pillar which is less that the reduction in the longitudinal extent of the pillar. Further is shown a process for manufacturing of a compressible pillar, a method of producing a VIG unit as well as a VIG unit.

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 door is provided that includes a door panel having a periphery and opposite first and second panel surfaces, stiles and rails collectively surrounding the panel, and sealant. The stiles have channeled stile surfaces extending across a thickness of the stiles and facing one another. The rails have channeled rail surfaces extending across a thickness of the rails and facing one another. The channeled stile surfaces and the channeled rail surfaces include channels with open ends that receive the periphery of the panel, first grooves positioned at first interfaces of the first panel surface and first edges of the open ends of the channels, and second grooves positioned at second interfaces of the second panel surface and second edges of the open ends of the channels. The sealant is received in the first and second grooves, preferably forming a water-proof seal.
