Abstract
A method for filling insulating glass units with gases other than air by dispensing cryogenic liquids into the inner space of these units which then evaporates to the gaseous state. The method is more efficient and effective accomplishing acceptable gas concentrations in less time, than charging gases directly into the unit.
