Dual-pane thermal window with liquid crystal shade
First Claim
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) affixing to said panes a plurality of liquid crystal cells, each of said cells being affixed to a different one of said panes; and
(c) delimiting within said window frame a plurality of spaces providing a plurality of thermal breaks, each of said spaces being delimited between a wall of each of said cells and a face of each of said panes.

Abstract
A dual-pane thermal window unit comprises two non-intersecting or, preferably, substantially parallel, spaced window panes, mounted in a window frame, a first of the panes having affixed thereto a first wall of an electro-optical liquid crystal cell providing a selected light transmittance, and a second of said panes delimiting, with a second wall of said cell, a space providing a thermal break. Each of the first and second walls comprises an electrically conductive film composed of plastic and having sufficient supporting strength to maintain the structural integrity of the cell. The window is light weight, economical to manufacture and efficient and reliable in operation.
