An insulating glass unit and a method of forming same comprising a pair of glass panes in a parallel, spaced apart relation, at least one edge spacer and at least a primary sealant located between adjacent edges of the pair of panes to provide an integral sealed unit defining a space therebetween, and at least one transparent film located within the space between the pair of glass panes, the at least one transparent film secured to one of a support structure and the at least one edge spacer, wherein the film is positioned in a spaced apart parallel relationship between the pair of glass panes, and wherein the film is annealed to a relaxed state prior to positioning of the film between the pair of glass panes.

1) Hot-melt single component sealant composition, comprising from 70% to 99 weight % of polyisobutylene based on the total weight of the composition. 2) Use as a primary sealant in a manufacturing process of Insulating Glass units.

An object is to enable sealing of a peripheral portion of a glass panel with less effort and time. A first metal introduction device 5A is moved from one first corner A at which two sides intersect each other of a pair of rectangular glass plates, toward another end of a first side Vab of the two sides, while performing filling with a metal material. Before the metal material filling the first corner A is solidified, a second metal introduction device 5B is moved from the first corner A toward another end of another second side Vad, while performing filling with a metal material. After the first side Vab and the second side Vad are filled with the metal material, both glass plates are rotated by 180 degrees, and the first metal introduction device 5A is moved toward another end of a fourth side Vcd of two sides intersecting each other at a second corner C diagonal to the first corner A, while performing filling with a metal material. Before the metal material filling the second corner C is solidified, the second metal introduction device 5B is moved from the second corner C toward another end of another third side Vbc, while performing filling with a metal material.

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.

A device for delivering a sealant material includes a first nozzle having a first nozzle head and a second nozzle having a second nozzle head. The first and second nozzle heads each independently have an outlet, an inlet opposite the outlet, and an open channel that extends through a body of the nozzle heads from the inlet to the outlet. The first nozzle is spaced apart from the second nozzle to form a space between the nozzle heads to allow a component to enter a first side of the device and exit a second side of the device while passing by the first and second nozzle heads. A notch is formed through the body of each of the first and second nozzle heads at a side where the component exits the device to distribute a sealant material onto each side of the component.

Door for a refrigerated cabinet, formed by multiple glazings that join a spacer frame, peripheral joints, and a reinforcement that makes it possible to do away with frame elements. The door comprises transparent vertical joints that connect the glass sheets of the glazing to transparent spacers.

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 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.

A privacy glazing structure may include an electrically controllable optically active material, such as a liquid crystal material, sandwiched between a flexible substrate and a rigid substrate. The flexible substrate and the rigid substrate may each have a conductive layer deposited on the surface facing the optically active material. The flexible substrate may be bonded about its perimeter to the rigid substrate and may be sufficiently flexible to conform to non-planarity of the rigid substrate. As a result, the flexible substrate may adopt the surface contour of the rigid substrate to maintain a uniform thickness of optically active material between the flexible substrate and the rigid substrate.

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.
