Multi-pane window structure
First Claim
1. In an insulative multi-pane window structure interposable between a colder region and a warmer region to permit vision therebetween, of the type having at least a first pane having a surface exposed in use to humidity-bearing air in the warmer region and a second pane opposite and spaced apart from the first pane, and having electrical heating means on the first pane for heating the first pane by electrical resistance heating, the improvement comprising:
- a substantially transparent, electrically inactive infrared reflective coating on the second pane.

2. An insulative multi-pane window structure interposable between a colder region and a warmer region, comprising:
-
a first window pane having outside and inside surfaces and having a transparently thin coating of electrically conductive, electrically resistant material disposed on its inside surface, said coating being adapted to generate heat upon the application of electrical potential thereacross; a second window pane having outside and inside surfaces, said inside surface being disposed a discrete distance from and facing the inside surface of the first window pane; and transparently thin film means of electrically inactive, infrared reflective material disposed on one of said side surfaces of the second window pane, for reflecting heat generated by the electrically resistant material away from the second window pane. - View Dependent Claims (3, 4, 5, 6, 7, 8, 9)
