The present disclosure relates to a vacuum insulated glazing (VIG) unit and tempered glass pane therefore. Furthermore, the present disclosure relates to a window comprising a VIG unit enclosed in a frame. Also, the present invention relates to a method of producing a tempered glass pane for a VIG unit, a method for producing a VIG unit and the use of a tempered glass pane as described herein in a VIG unit and the production thereof.

An improved glazing unit extending along a plane, P, defined by a longitudinal axis, X, and a vertical axis, Z; having a width, DW, measured along the longitudinal axis, X, and a length, DL, measured along the vertical axis, Z, including a glass panel, a housing able to accommodate a communication device and an opening arranged on the glass panel. The present invention also discloses a communication system including a glazing unit, at least a 4G and/or 5G signal communication unit and a provider fixed station or active or passive repeater, which is placed at least at 1 m outside from the glazing unit, wherein the 4G and/or 5G signal communication unit is fixed to the glazing unit at the opposite side from the provider fixed station or active or passive repeater.

Pillar delivery films for vacuum insulated glass units are disclosed. The delivery films include a support film or pocket tape, a sacrificial material on the support film, and a plurality of pillars. The pillars are at least partially embedded in the sacrificial material or formed within sacrificial material molds, and the sacrificial material is capable of being removed while leaving the pillars substantially intact. Methods of transferring pillars to a substrate using the pillar delivery films are disclosed. In order to make an insulated glass unit, the delivery films are laminated to a receptor such as a glass pane, and the support film and sacrificial material are removed to leave the pillars remaining on the glass.

A flexible spacer for an insulated translucent panel assembly. The flexible spacer includes a flexible thermoset extrudate formed from a two component flowable polymeric formulation and being a flowable mixture. One component carries a desiccant powder, and the other component is a catalyst for curing the extrudate. The flowable mixture is directly cast on to a vapor barrier web. The vapor barrier web includes a length and a width, the length being greater than the width. The vapor barrier web includes a corrugated sheet of material having a plurality of corrugations oriented generally orthogonal to the length of the vapor barrier web.

A non-light-emitting, variable transmission device can include a first substrate, a first transparent conductive layer, an electrochromic layer, a second transparent conductive layer, a second substrate; and an interlayer disposed between the first substrate and the second substrate. The non-light-emitting, variable transmission device is configured such that a failure of the non-light-emitting, variable transmission device is less likely than another non-light-emitting, variable transmission device in which the interlayer directly contacts the second transparent conductive layer and has a moisture content of at least 0.08 wt %. In an embodiment, the interlayer has a moisture content of at most 0.05 wt %. In another embodiment, the non-light emitting, variable transmission device further includes a barrier layer disposed between the second transparent conductive layer and the interlayer, wherein the barrier layer extends at least partly through the second transparent conductive layer or seals off a passageway.

Method for the production of a vacuum insulated glazing unit with more than two panes and a vacuum insulated glazing unit with more than two panes. In one example a triple pane vacuum insulated glazing assembly is fused and the cavity is backfilled during cooling whereby the centre pane temperature may be lowered. This has the advantage of keeping the stresses below the failure boundaries and enabling faster production.

A transparent polymer film for light redirection includes a carrier layer and a structured layer in optical contact with each other. The structured layer has a multitude of curved metallic micromirrors, which are parallel to each other and encapsulated in a transparent material and separated by a periodicity distance (p) of 10 to 1000 micrometer parallel to the film surface. 50% or more of the micromirrors’ surfaces have a cross section, perpendicular to the film surface, in the form of elliptic arcs, whose radii are from the range 5 p to 25 p, and the micromirrors are arranged in a depth (d) perpendicular to the film surface from the range 1.6 p to 3.0 p, especially 2 p to 2.5 p. Glazings can be equipped with the film.

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.
