Abstract
A glass sheet suitable for use as the panoramic roof of a motor vehicle is disclosed, the sheet being comprised of a tinted glass coated with a network of enamel patterns which reduce the light and energy transmission factor of the formed glass. The glass may optionally include a thin semireflective layer deposited on one side of the glass. Preferably, the light transmission factor and energy transmission factor of the coated glass sheet are approximately equal, and below 30%.
