APPARATUS AND METHOD FOR SOLAR HEAT GAIN REDUCTION IN A WINDOW ASSEMBLY
First Claim
1. A method of manufacturing a window assembly having a pane of material and a plurality of spaced-apart micro-louvers positioned in the pane of material, the micro-louvers positioned to block transmission of direct sunlight through the pane when the sun is at a selected angle above the horizon or higher, the method comprising:
- positioning a first pane of material parallel to and spaced apart from a second pane of material, a gap between the panes;
arranging ribbon of micro-louver material in a pattern having a plurality of parallel, spaced-apart micro-louvers extending substantially across the length of the window assembly, the pattern positioned to be in the gap;
pouring curing material into the gap and between the plurality of parallel, spaced-apart micro-louvers;
curing the curing material to create a pane of curing material, the plurality of micro-louvers positioned therein.

Abstract
A window assembly having at least one pane is presented for use in a building. Positioned within the pane are a plurality of spaced-apart micro-louvers which extend substantially across the length of the pane. The micro-louvers are positioned to block transmission of direct sunlight through the pane when the sun is at a selected angle above the horizon or higher. The angle at and above which direct light is blocked can be selected to be approximately 30 or 45 degrees above the horizon, for example. The angle can be selected based on the latitude of the location of the window assembly, the time of day during which direct sunlight is blocked, etc. The micro-louvers may have reflective surfaces, be colored as desired, be opaque or translucent.
