ABSTRACT:
The present invention provides a window assembly having a transparent panel and a conductive heater grid formed integrally with the transparent panel. The conductive heater grid has a first group of grid lines and a second group of grid lines, with opposing ends of each group being connected to first and second busbars. Grid lines of the second group are spaced between adjacent grid lines of the first group, with the width of the grid lines themselves in the second group being less than the width of the grid lines in the first group.
