Title: Heated windows having vacuum-deposited layers

Abstract: A glass sheet is provided with a metallic layer and auxiliary dielectric layers, at least one of the auxiliary layers being formed of a deposit of a heavy metal tungsten or molybdenum trioxide. The metallic trioxide may form an anchoring layer, and is advantageously of an interference thickness. Particular procedures for forming electric terminals for supplying heating current to the metallic layer are described. Laminated glazings with an intercalary plastic layer over the metallic trioxide layer are described.
