A glass panel unit includes: a first panel; a second panel facing the first panel; a sealing member bonded to respective facing peripheral portions of the first panel and the second panel; and at least one spacer provided in a reduced pressure space between the first panel and the second panel. The at least one spacer includes a resin body and at least one ultraviolet protective layer provided on a surface of the resin body.

An insulating glazing includes at least two substantially parallel glass sheets, which are spaced apart by at least one air- or gas-filled cavity forming a cavity internal to the glazing, a spacer, which is arranged at a periphery of the glass sheets and which keeps the two glass sheets spaced apart, and an adhesive bonding system arranged to fasten the spacer to each glass sheet via two of opposite fastening faces of the spacer, wherein the spacer includes, at least for one side of the glazing, a mirror-function reflective surface on an internal face of the spacer facing the internal cavity of the glazing.

Methods for manufacturing insulating glass units (IGUs) include providing an unsealed IGU assembly that has first and second sheets of glass material and at least one spacer frame between the first and second sheets and sealed to at least one of the first and second sheets. The unsealed IGU assembly defines an interpane space and an IGU passage providing fluid communication between the interpane space and an environment external to the interpane space. In some cases the method includes positioning a filling device next to the IGU passage and introducing a gas into the interpane space through the IGU passage using the filling device. In some cases the method includes delivering a sealing material or sealing structure to the IGU passage with the filling device to seal the interpane space. Corresponding systems for manufacturing IGUs are also provided.

Embodiments herein relate to window spacer assemblies including surfaces with relatively high surface energy. In an embodiment, a window spacer assembly is included. The window spacer assembly including a spacer body having an inner surface, an outer surface, and lateral surfaces. The window spacer assembly further includes a first sealant disposed on the lateral surfaces. Portions of the window spacer assembly such as an outer surface or lateral surface of the spacer body and/or a moisture vapor barrier layer disposed over the outer surface can be treated to have a higher surface energy. Other embodiments are also included herein.

Method and Apparatus for fabricating a spacer frame for use in an insulating glass unit. One of a multiple number of possible spacer frame materials is chosen for the spacer frame. An elongated strip of the material is moved to a notching station where notches are formed at corner locations. The character of the notches is adjusted based on the selection of the metal strip material and more particularly to achieve bending of the material in an repeatable, straightforward manner. Downstream from the notching station the metal strip is bent into a channel shaped elongated frame member having side walls. Further downstream a leading strip of channel shaped material is severed or separated from succeeding material still passing through the notching and bending station.

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.

An insulated glass unit (IGU) assembly station can include an assembly table, a conveyor assembly, and a projection component. The assembly table can have a table surface configured to receive first and second transparent window components, the table surface being positioned at an incline relative to a vertical position. The conveyor assembly can be configured to translate the first and second transparent window components along a translation pathway from a first end of the table surface to a second end of the table surface, the translation pathway being substantially parallel to the table surface. The projection component can be adjacent to the assembly table and can be configured to engage the first transparent window component to translate at least a bottom portion of the first transparent window component between an initial position and a first assembly position offset from the translation pathway.

The technology disclosed herein generally relate to assembly equipment for window units. In one embodiment, a window unit assembly system is taught that has a frame component that is configured to support equipment for a window unit assembly line. A pane conveyor is supported by the frame component and is configured to move panes along the window unit assembly line. A spacer conveyor is supported by the same frame component as the pane conveyor and is configured to move spacer elements along the window unit assembly line.

An insulating glazing unit having a first pane, a second pane, a third pane arranged between the first pane and the second pane, an outer pane interspace, an inner pane interspace, and a spacer is described. The spacer having a plastic profile with a first glazing interior surface and a second glazing interior surface, a first pane contact surface, a second pane contact surface, a primary sealing means, and a main member containing a sealing material and a drying material. The plastic profile includes a groove, into which the third pane is inserted and which runs parallel to the first pane contact surface and to the second pane contact surface. The plastic profile separates the outer pane interspace from the inner pane interspace. The main member is arranged in the outer pane interspace between the plastic profile and the primary sealing means, the main member being adjacent the plastic profile and the primary sealing means.
