Abstract
The invention relates to a transparent substrate provided with a thin-film multilayer comprising a metallic layer having infrared-reflection properties located between two, subjacent and superjacent, nonmetallic dielectric coatings, the superjacent dielectric coating comprising the sequence of thin layers deposited in the following order: The invention allows the solar factor of a multiple glazing unit to be increased, and an acceptable color, especially in transmission, which is in particular less green, even also less yellow, to be obtained for a multiple glazing unit.
