Superwindow

A window with a very low U-value achieved through the use of multiple glazings, low-E (low-emissivity) coatings, and inert gas fills, usually argon or krypton, placed between sealed panes of glazing in order to provide resistance to heat flow.

Similar coordinating benefits are achieved in many integrated engineering designs by using superwindows, daylighting devices, and alternative HVAC designs that regulate the temperature of the people as opposed to the spaces.
In the superwindows, argon gas, which is inexpensive, nontoxic, clear and odorless, fills up the cavity to increase thermal performance.
