Argon Filled Double Glazed Units

Argon Filled Double Glazed Glass Units

To increase the efficiency of an insulated glass unit, an inert gas is usually inserted into the airspace between the panes of glass. These gases are inert, harmless, and invisible.

Argon gas is typically used in double pane windows, since it performs best when the units panes of glass are at least 1/2" apart. Argon is 6 times denser than air, and it slows the transfer of heat and cold through the glass unit - improving the overall efficiency.
