Patent ID: 8231977

Claim:
A multilayer sunshield lamination structure formed on a sheet of vitreous material comprising: at least one functional layer composed of a silver-based material that reflects infrared radiation; at least two dielectric coatings, one of which is the first dielectric coating deposited directly onto the sheet of vitreous material and the other lies on the outside in relation to the functional layer or layers, each functional layer being surrounded by dielectric coatings; and an essentially metal absorbent material based on at least one of the following elements selected from the group consisting of: Rh, Ru, Os, Co, La, Ce, Pr, Nd, Mo, Mn, Hf, and alloys thereof forming at least part of a separate layer from the functional layer and deposited under or on, and in direct contact with, the functional layer, wherein said lamination structure, when deposited on an ordinary clear soda-lime float glass sheet 6 mm thick, has a solar factor SF of less than 45% and a light transmission LT of less than 70%.
