The invention provides an IG unit that includes two glass sheets and an aerogel sheet located between the two glass sheets. The aerogel sheet is adhered to an interior surface of one of the two glass sheets by an adhesive, such that a face of the aerogel sheet is carried alongside the interior surface and has a portion that is devoid of the adhesive. In some cases, the adhesive is outside a vision area of the unit. In some cases, the adhesive securing the aerogel sheet to the interior surface is in contact with the first face of the aerogel sheet, and the adhesive contacts less than 10% of the first face of the aerogel sheet. Furthermore, some embodiments provide a glazing assembly that includes a frame and an IG unit mounted in the frame such that a vision area of the glazing assembly is located inwardly of the frame.

A desiccant window includes: a transparent triangular prism that is disposed between first and second plates, is configured of a first side along the first glass and second and third sides which have an angle with respect to the first side in a sectional view, and forms (three) types of optical paths; and a desiccant heat receiving unit that has hygroscopicity and is disposed between the first and second plates, is installed on the second side of the triangular prism), and is received solar heat and releases absorbed moisture by heating using the received heat received.

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.

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 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.

A structural body includes a refrigerant between a first plate and a second plate. A circulation structural part between the first and second plates includes a reservoir portion provided on a first plate side. In the circulation structural part, the refrigerant from the reservoir portion which has evaporated due to heat of the first plate side reaches a second plate side, condenses on the second plate side and is returned to the reservoir portion again. A temperature sensitive mechanism is in a first state when a temperature of the first plate side is equal to or higher than a predetermined temperature to allow refrigerant circulation, and is in a second state different from the first state when the temperature is lower than the predetermined temperature to prohibit the refrigerant circulation.

Examples of the present disclosure provide an overhead door panel. The overhead door panel includes a pair of parallel glass panes, a metal frame with parallel lateral stiles oriented perpendicular to the pair of parallel glass panes, a first seal system located at a first lateral stile, and a second seal system located at a second lateral stile, wherein the first seal system and the second seal system engage with at least one glass pane of the pair of parallel glass panes and a lateral stile of the parallel lateral stiles of the metal frame such that the first seal system and the second seal system are between the at least one glass pane and the lateral stile.

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.

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.

An evacuated glazing assembly has first and second spaced-apart, non-metal substrates connected to each other by a seal element to form an evacuable interior space therebetween. The seal element is formed by bonding a metallic bridge element to at least one of the substrates by cold welding to form a first stage seal and forming a second stage seal at least partially in contact with the first stage seal. The seal element is configured to hermetically isolate the interior space from the surrounding environment, and both the first stage seal and the second stage seal contribute to the hermeticity of the seal element.
