A five-layer coating, commonly called a “stack”, for glass windows in order to control the proportion of solar radiation permitted to pass through the window, the remainder being reflected by the coating, while maintaining a desired visible light characteristic transmission. Particularly, the technique is applied to vehicle glass windows, such as truck and automobile windshields, where the amount of solar radiation allowed to pass into the vehicle through the window is minimized within the constraints of maintaining visible light transmission above a certain legal level. The characteristics of the coating are also selected for visible light reflected from the window to the outside to be a substantially neutral color, highly desirable for the overall appearance of trucks and automobiles.
