Abstract
A multilayer sunshield lamination structure foamed on a sheet of vitreous material which includes at least one functional layer composed of a silver-based material that reflects infrared radiation and at least two dielectric coatings, each function layer being 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 is composed of an essentially metal absorbent material based on the following elements: Pd, Pt, Au, Tr, Rh, Ru, Os, Co, Ni, Cu, Cr, La, Ce, Pr, Nd, W, Si, Zn, Mo, Mn, Ti, V, Nb, Hf, Ta and alloys thereof arranged in the immediate vicinity of the functional layer or included in this functional layer.
