Provided is a glass panel capable of, even after elapse of a long period, reliably sealing a suction hole and keeping a gap in an airtight state. A suction hole sealing metal material 15 has a first protruding portion 15a formed on an atmospheric side around a suction hole 4, and a second protruding portion 15b formed on a gap side around the suction hole 4, and as seen in a thickness direction of the glass plates 1A, 1B, a first contour 16a which is an outermost edge of a first adhesion surface portion S1 where the first protruding portion 15a is in contact with an atmospheric-side surface 17A of the glass plate 1A, and a second contour 16b which is an outermost edge of a second adhesion surface portion S2 where the second protruding portion 15b is in contact with a gap-side surface 17B of the glass plate 1A, are on an outer side of a third contour 16c which is a gap-side hole edge of the suction hole 4.

Embodiments herein relate to methods and apparatus for preventing and mitigating the ingress of moisture into an interior region of an IGU. Various techniques are disclosed including, for example, the use of a strain relief structure around wires passing through a secondary seal, improved materials for coating the wires, and additional/improved layers for bonding the secondary seal to tape provided around a spacer.

A vacuum glazing includes a vacuum layer formed between a first glazing and a second glazing, a spacer provided in the vacuum layer, a frame provided at edge portions of the first and second glazings, and a sealant interposed between the frame and surfaces of the first and second glazings to perform sealing of the vacuum layer. The insulating performance of the vacuum glazing is improved.

An installation system to fabricate the multiple glazing units at the installation site is provided. The installation system includes a primary glazing unit, a secondary glazing unit, a spacer element, a primary sealant, a fixture, a secondary sealant and a dispenser. The installation system includes a fixture to apply the primary sealant on the spacer element. The installation system also includes a dispenser to apply the secondary sealant to a clearance between the primary glazing unit and the secondary glazing unit.

An insulating glazing includes a first a second pane, a circumferential spacer between the first and second pane that is fixedly connected to the first and second pane in a water-vapor-tight manner in each case, which spacer has two parallel pane contact walls, an outer wall, and a glazing interior wall and an interior, and a water-tight sealant strip running around the outer wall between the first and second pane. A pressure-equalizing element is inserted into the sealant strip and the spacer, which pressure-equalizing element is open to the surrounding atmosphere and to the interior of the spacer or to the glazing interior between the first and the second pane and is implemented such that it provides a gas connection having a pressure-equalizing function between the atmosphere and the interior of the spacer or the glazing interior which gas connection is temporally limited due to aging and/or atmospheric influences.

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/Z21.30).

A foam spacer applicator may include: a conveyer unit configured to automatically transfer a glass panel; a foam head unit disposed at a predetermined distance from the front side of the conveyer unit, and configured to automatically supply and bond a spacer to the glass panel transferred from the conveyer unit through a combination of an X-axis horizontal operation and a Y-axis elevation operation through an elevation guide plate disposed with a vertical structure; and a magazine unit disposed at a predetermined distance from the rear side of the foam head unit, and configured to inject and apply a sealant to both surfaces of the spacer while adjusting tension of the spacer, and automatically supply the spacer to the foam head unit.

An insulating glazing includes at least one first pane element, at least one spacer, and at least one connector. The spacer and the connector are arranged next to each other such that they extend along a common longitudinal axis, wherein the spacer and the connector accommodate and position the first pane element. The connector has at least one first electrically conductive conductor element such that an electrical connection can be established between an external power source and the first pane element via the first conductor element.

Materials and methods for preparing thick, mesoporous silica monolithic slabs and coatings with high transparency and low thermal conductivity are provided. The transparent silica materials are particularly suited for window or solar applications including insulation barriers for existing or new single, double pane windows or glass panel building components. The template-free, water-based sol-gel methods produce slabs or coatings by gelation of a colloidal suspension of silica or other oxide nanoparticles or by ambigel formation and then ageing and drying the gels under ambient conditions. Solvent exchanges with nonpolar, low-surface-tension solvents help to avoid cracking caused by drying stress. Mesoporous slabs can also be cast in molds on perfluorocarbon liquid substrates to reduce adhesion and enable gels to shrink freely during aging and drying without incurring significant stress that could cause fracture.

A glass panel unit manufacturing method includes a punching step and a pillar mounting step. In the punching step, a punch punches at least one of a plurality of portions from a base material of a sheet to form at least one pillar. Each of the plurality of portions is surrounded by a corresponding one of a plurality of loop-shaped grooves in the base material. In the pillar mounting step, the at least one pillar is mounted on a surface of a first substrate including a glass pane.
