INSULATING GLASS UNIT FILLED WITH ADSORBABLE GAS

摘要

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.

1. A method comprising:
filling a between-pane space defined between a first pane of transparent material and a second pane of transparent material with a plurality of gases, wherein the plurality of gases include a first gas composition and a second gas composition; positioning a spacer between the first pane of transparent material and a second pane of transparent material so as to seal the between-pane space from gas exchange with a surrounding environment, wherein the spacer comprises a gas adsorption material configured to adsorb the first gas composition; and reducing a gas pressure in the between-pane space via adsorption of the first gas composition by the gas adsorption material so that the gas pressure in the between-pane space is reduced below atmospheric pressure.
