Abstract
The window is comprised of upper and lower sashes. Each sash includes two panes of glass with an air space barrier therebetween. All metal members on one face of each sash are thermally and electrically insulated from corresponding members on the opposite face of each sash to thereby provide a complete thermal and electrical barrier between the indoor and outdoor faces of the sashes.
