This disclosure describes insulated glass units (IGUs) that incorporate electrochromic devices. More specifically, this disclosure focuses on different configurations available for providing an electrical connection to the interior region of an IGU. In many cases, an IGU includes two panes separated by a spacer. The spacer defines an interior region of the IGU and an exterior region of the IGU. Often, the electrochromic device positioned on the pane does not extend past the spacer, and some electrical connection must be provided to supply power from the exterior of the IGU to the electrochromic device on the interior of the IGU. In some embodiments, the spacer includes one or more holes (e.g, channels, mouse holes, other holes, etc.) through which an electrical connection (e.g., wires, busbar leads, etc.) may pass to provide power to the electrochromic device.

This present invention generally relates to the manufacture and application of a vented glazing system to existing glazed units or new glazing units. More particularly this invention relates to a method of glazing and a glazing system that will increase thermal performance and reduce condensation for existing glazed units.

The present disclosure relates to a vacuum insulated glazing unit, to the use thereof and to a method of manufacturing such a unit. The vacuum insulated glazing comprises a first glass pane, having a first interior major surface and a first exterior major surface and a second glass pane having a second interior major surface and second exterior major surface, the glass panes being arranged in parallel with said interior major surfaces facing each other. The VIG unit further comprises a low emissivity coating deposited on at least the first interior major surface, an edge region in proximity to the edge of the first glass pane, defined as where none or a reduced part of the low emissivity coating is present, and a side seal comprising a glassy seal material arranged at a minimum separation distance (d1_min) from said low emissivity coating, so that an intermediate part of said edge region between said glassy sealing material and said low emissivity coating is not bonded to said glassy sealing material, or a side seal arranged at a minimum separation distance (d1_min) of at least 1.5 mm, such as at least 2 mm, or such as at least 3 mm from said low emissivity coating.

This invention provides a sealing spacer for spacing apart two window panes to form a window assembly. The spacer has an elongated, flexible strip having opposed edge surfaces and opposed side surfaces. The spacer also has a fiber reinforced polymer layer over the elongated, flexible strip. The opposed edge surfaces undulate with crests and troughs. The spacer has an activatable sealant for directly sealingly securing the flexible strip to each of the two window panes. The activatable sealant is on each of the opposed side surfaces of the fiber reinforced polymer. The invention also provides methods for making the spacer and window assembly.

The glass panel unit includes a first glass panel, a second glass panel, a seal, an evacuated space, and a spacer. The second glass panel is placed opposite the first glass panel. The seal with a frame shape hermetically bonds the first glass panel and the second glass panel to each other. The evacuated space is enclosed by the first glass panel, the second glass panel, and the seal. The spacer is placed between the first glass panel and the second glass panel. The spacer is a stack of two or more films. At least one film of the two or more films contains a polymer having a viscoelastic coefficient at 400° C. larger than 500 MPa.

An object is to enable suppression of thermal leakage at a peripheral portion of a pair of glass plates disposed so as to be opposed to each other with a gap interposed therebetween. A pair of glass plates 1A, 1B are disposed so as to be opposed to each other with a gap V interposed therebetween, and a periphery sealing metal material 3 is provided which joins the pair of glass plates 1A, 1B at a peripheral portion V1 thereof so as to seal the gap V in an airtight state. The periphery sealing metal material 3 interposed between opposed inner surfaces of the pair of glass plates 1A, 1B contains, in a mixed manner, a thermal insulation material 30 having lower thermal conductivity than that of the periphery sealing metal material 3.

A method for manufacturing a glass panel unit includes an assembling step, a bonding step, a gas exhausting step, a sealing step, and an activating step. The bonding step includes melting a peripheral wall in a baking furnace at a first predetermined temperature to hermetically bond a first glass pane and a second glass pane together with the peripheral wall thus melted. The gas exhausting step includes exhausting a gas from an internal space through an exhaust port in the baking furnace to turn the internal space into a vacuum space. The sealing step includes locally heating to a temperature higher than a second predetermined temperature, and thereby melting, either a port sealing material or an exhaust pipe to seal the exhaust port and thereby obtain a work in progress. The activating step includes activating a gas adsorbent after the sealing step to obtain a glass panel unit.

A spacer for a multi-pane insulating glazing unit includes a spacer body made from a first material with first and second hollow desiccant chambers extending in a longitudinal direction and a longitudinal groove between the first and second chambers open to a first side of the spacer for holding an intermediate pane of the glazing unit, the groove being delimited in a width direction by first and second side walls and having a bottom wall, and the spacer body having a gas barrier on a second side opposite the first side. The first side wall and/or the second side wall and/or the bottom wall of the groove include at least two electrically conductive portions electrically isolated from each other and configured to make electrical contact with at least one electrical contact of the intermediate pane.

The task of the invention is to create a reliable manufacturable and also universally usable multi-pane doors of refrigerated cabinets while maintaining the required stability, which is simplified in design and additional functions can be provided or can be subsequently integrated without additional effort. In addition, the manufacturing process is to be simplified.
