Abstract: An insulating glass unit may be fabricated by filling the space between opposed panes of glass with multiple types of gases and then sealing the gases in the space. A spacer containing a gas adsorption material may be positioned between the panes of glass to seal the gases in the space. In some examples, the gas adsorption material is configured to selectively adsorb one of the gases introduced into the space but substantially none of another of the gases introduced into the space. As a result, the gas pressure in the insulating glass unit may reduce below the initial filling pressure after fabrication of the unit due to adsorption. Such gas pressure reduction may be useful, for example, if the insulating glass unit is going to be used at a higher elevation location where the air pressure is lower.

Abstract: The invention provides a spacer having an engineered wall with multiple corrugation fields including first and second corrugation fields having differently configured corrugations. Also provided are multi-pane glazing units that incorporate such a spacer.

Abstract: A photovoltaic glazing assembly including first and second substrates, at least one being formed of a light transmitting material. The assembly includes a photovoltaic coating over at least the central region of a surface of the first substrate or the second substrate. In some embodiments, a seal system encloses a gas space between the substrates and optionally has a thickness of between approximately 0.01 inch and approximately 0.1 inch. Certain embodiments provide a flexible and electrically non-conductive retention film over the photovoltaic coating. Additionally or alternatively, the assembly can have a peripheral seal system with relative dimensions in certain ranges. Advantageous manufacturing methods are also provided.

Abstract: A photovoltaic glazing assembly including first and second substrates joined together and spaced apart, on either side of an airspace, by a seal system formed of a first seal and a second seal. A photovoltaic functional coating is disposed over a second major surface of one of the substrates, which faces the second major surface of the other substrate. Lead wires are coupled to bus bars and/or electrical contacts affixed to the functional coating and routed out from the airspace. Affixing the seal system to the first and second substrates, in order to join the substrates together, may be accomplished by applying pressure to the substrates.

Abstract: A photovoltaic assembly including first and second substrates joined together and spaced apart, on either side of an airspace, by a seal system formed of a first seal and a second seal, the second seal comprising one or more silyl terminated polyacrylate polymers.

Abstract: A method for repairing an insulating glass unit and apparatus to facilitate such repair. A bore is drilled through a frame encasing an insulating glass unit to expose the peripheral spacer of the unit, and a hole is drilled through a wall of the spacer to enable air to enter the space between the panes. The hole in the spacer is then sealed, for example, with a rivet, and the bore in the frame is then filled and sealed as well.

Abstract: A connector key for joining spacer member ends in multi-pane window units. A connector key and methods for joining spacer member ends are provided. The connector key can include a top central depression, side walls having top gaps, side shoulders having channels and recesses, all providing opportunity for sealant to flow from the central depression over the side regions of the connector key. Connector keys can also have holes through the bottom floor of the central depression to the bottom of a connector key and further through bottom channels provided in the connector key. Methods are provided which include sliding a spacer member over each end of the connector key up to a central flange. Holes may be punched through the spacer material, preferably forming jagged portions which secure the spacer members to the connecting key. Sealant may be injected through the punched holes, and through the through holes in the connector key central depression floor.
