Abstract (en)

[origin: CA3125787A1] The invention relates to a substrate which is coated on one of its faces with a stack of thin layers having reflection properties in the infrared and/or in solar radiation, comprising two metallic functional layers, in particular on the basis of silver. Each of the metallic functional layers is disposed between two dielectric coatings. According to the invention, the dielectric coating (Di2) situated between the two functional layers (F) comprises at least one absorbent layer (A) which absorbs solar radiation in the visible part of the spectrum. It has been found that for a stack for laminated glazing, some symmetry at the functional metal layers and the dielectric layers 1 and 3 is favorable. The invention also relates to laminated glazings comprising such a substrate coated on side 2.
