ABSTRACT:
A thermally insulating window (2) is created by filing the space (16) between two window panes (4, 6) with a gas exhibiting low thermal conductivity at a moderately low pressure so to substantially eliminate convection heat flow through the insulating region but not so low as to substantially reduce conduction heat flow through the insulating region. Doing so greatly increases the thermal insulating qualities of the window without the problems associated with evacuating the region to extremely low pressures. The seal (14, 50) at the edge (10, 12) of the window panes can define one or more barrier regions (44, 46) which reduce air leakage into the insulating region.
