Abstract: Insulating glass units and techniques for manufacturing insulating glass units are described. In some examples, a manufacturing technique involves filling a between-pane space located between a first glass pane and a second glass pane of an insulating glass unit with an insulative gas to ambient pressure at the location where the insulating glass unit is manufactured. The insulating glass unit can include one or more features allowing the pressure of the insulative gas to be adjusted (increased and/or decreased) after initial fabrication of the insulating glass unit. For example, the insulating glass unit can include one or more features allowing the pressure of the insulating gas to be adjusted from ambient pressure at the location of manufacture to a different ambient pressure corresponding to an elevation where the insulating glass unit is intended to be delivered and installed in a building.
