Variable solar control window assembly
First Claim
1. A window assembly for controlling solar transmission including a pair of transparent sheets mounted in a frame in spaced apart generally parallel planes, comprisinga filter material sheet having a coating of induced transmission filter material over at least a portion of said filter material sheet and mounted for movement in the frame along a path between the transparent sheets, said filter material sheet having relatively high solar visible transmission and substantially less solar transmission outside the visible spectrum over said portion of said filter material sheet;
- andmeans for selectively moving said filter material sheet along said path whereby the solar transmission through the assembly is varied.

Abstract
A variable solar control window assembly includes a pair of spaced parallel planar transparent sheets mounted in a frame. An induced transmission filter sheet is selectively movable between the transparent sheets for varying the solar transmission through the window assembly. The filter sheet includes a carrier layer and one or more coating layers, each coating layer formed as a layer of reflective metal material between two layers of dielectric material. The filter sheet can have bearing/protective layers or strips adhered thereto to seal against the frame and to assist in the sliding movement of the filter sheet with respect to the frame. One or both of the transparent sheets can include an anti-lacerative material layer.

7. A window assembly for controlling solar transmission comprising:
-
a frame defining a window aperture; a pair of generally parallel, spaced apart planar transparent sheets mounted in said frame and closing said window aperture; a filter sheet including an induced transmission filter film over at least a portion of said filter sheet and mounted for movement in said frame along a path between said transparent sheets, said filter sheet having at least a seventy percent Illuminant A transmission and substantially less solar transmission outside the visible spectrum over said portion of said filter sheet; and means for selectively moving said filter sheet along said path whereby solar transmission through said window aperture is varied.

8. A window assembly for varying solar transmission having a pair of generally parallel, spaced apart planar transparent sheets mounted in a frame defining a window aperture closure, comprising:
-
an induced transmission filter sheet having a carrier layer and a coating layer, said filter sheet having relatively high solar visible transmission and substantially less solar transmission outside the visible spectrum; means for slidably mounting said filter sheet between transparent sheets mounted in a frame; and means for moving said filter sheet along a predetermined path between the transparent sheets whereby solar transmission through a window aperture defined by the frame is varied. - View Dependent Claims (9, 10, 11, 12, 13, 14)
