1. A method for decreasing radiative and conductive heat transfer between the exterior and the interior of a building, comprising the steps of:
- (a) mounting within a window frame, a plurality of spaced window panes;
(b) delimiting between said window panes a first space providing a thermal break and a second space containing an electro-optical liquid crystal cell providing a selected light transmittance.

Abstract
A thermal-pane window unit having an electro-optical shade of adjustable transmittance is provided for reducing radiative heat transfer, as well as conductive transfer, between the exterior and interior of a building and, additionally, for presenting an attractive shaded window appearance. The invention utilizes a liquid crystal cell of selectable light transmittance in combination with a conventional dual pane heat insulating window. The liquid crystal material is preferably electro-optically responsive to a low voltage AC field.
