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.

An insulating glass unit cooling assembly and method of cooling an insulating glass unit is provided. The cooling assembly includes a cooling unit that directs air at insulating glass units and a conveyor that transports insulating glass units along a path of travel defining an axis of travel for the insulating glass units. The conveyor has a conveyor planar surface that supports a corresponding planar glass surface of the insulating glass units as the insulating glass units are conveyed along the axis of travel such that the planar surface of the insulating glass units are substantially horizontal and substantially parallel to the conveyor planar surface. The air from the cooling unit is directed in a path substantially parallel with the conveyor planar surface and the planar glass surface of the insulating glass units as the insulating glass units travel along the conveyor.

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.

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.

A conveyor belt for use in applying sealant to an elongated spacer frame and a method of use. The conveyor belt comprising a reversible belt rotatably attached to first and second pulleys. The reversible belt having a first perimeter length. The reversible belt is removably attached to the first and second pulleys. A first side and a second side of the replacement belt include first and second adhesive resistant materials. The first and second adhesive resistant materials are separated by an elastic support layer, wherein the first perimeter length is shorter than a second perimeter length measured about the rotation path of the first and second pulleys. The elastic support layer applies a force to first and second pulleys such that the reversible belt does not slip relative to the first and second pulleys.

The aim of the invention is to not use, partially or completely, the inner aluminium profile as a spacer in multi-pane doors of refrigerators whilst retaining the required stability and also to replace all other spacers with transparent glass spacer. The invention also relates to methods for the production thereof. The insulating glass elements for the multiple-pane doors with a transparent edge composite for use in shop fittings, refrigerator construction and special cabinet construction, comprise glass spacers (1) between the base disk (4) and the cover disk (4) in the vertical regions of doors and in the upper horizontal region or in both horizontal regions, aluminum or plastic spacers (2), and EVA film sheets (3) between the base disk (4) and the spacers (1, 2) and between the spacers (1, 2) and the cover disk (4), the EVA film sheets (3) are arranged in the four edge regions overlapping the vertical spacers (2) to the horizontal spacers (1). In another embodiment, the EVA film is replaced with ethylene vinyl acetate copolymer granulates, which is heated by means of a metering device and is applied in a liquefied form at the desired positions as thread-shaped strips. The crosslinking between the glass and the ethylene vinyl acetate copolymer occurs in the lamination oven.

An integrated glazing unit (IGU) includes a first pane, an electronic laminate that includes an electronic device provided between first and second substrates, a plurality of terminals coupled to the electronic device, and the first substrate being attached to the first pane. The IGU also includes a second pane coupled to the electronic laminated assembly by a spacer, the spacer being recessed with respect to the laminate edge and the second pane edge, forming an interpane volume, R, between the first and second panes. The IGU further includes a gutter having an open face and giving access to an inner volume, Vi. The gutter is positioned within the interpane volume, R, with the open face being recessed from, flush with or extending by less than 10 mm from the second pane edge. The gutter is suitable for receiving the male and/or female electric connector of a cable harness in the inner volume, Vi.
