Zusammenfassung:A glass sheet carrying a multilayer sunshield lamination structure is disclosed. The lamination structure includes at least one functional layer composed of a silver-based material that reflects infrared radiation and at least two dielectric coatings. The first dielectric coating is deposited directly onto the glass sheet and the other lies on the outside in relation to the functional layer or layers. Each functional layer is surrounded by dielectric coatings. The 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%. The lamination structure comprises a Si or metal absorbent material based on at least one of the following elements: Pd, Pt, Au, Ir, Rh, Ru, Os, Co, Cu, La, Ce, Pr, Nd, Si, Mo, Mn, V, Hf, and alloys of those elements arranged in the immediate vicinity of the functional layer or included in an amount of at least 5 atom% in this functional layer.
