Thermopanes

Thermopanes

A “thermopane” or double-paned window has two panes of glass, separated by a trapped air space. The trapped air acts as an insulator, reducing heat loss through the glass.

A common problem with windows of these types is that you can get fogging inside the window (between the panes of glass) which is indicative of a broken seal.
