Abstract: A material includes at least transparent substrate and has a functional coating or functional layer to act on solar radiation and/or infrared radiation. The material includes an absorbent element in the form of a layer, which in particular absorbs the solar radiation in the visible part of the spectrum and does so in a specific manner. The material has an absorption profile with at least a spike centered between 480 and 549 nm, and a second spike centered between 630 nm and 779 nm. The addition of a layer-form absorbent element exhibiting these two absorption spikes allows an improvement in thermal performance, particularly the selectivity, without having a great impact on the aesthetics of the glazing, so that in particular the transmission remains neutral.

Abstract: A substrate coated on one of its faces with a stack of thin layers having reflection properties in the infrared and/or in solar radiation, including two metallic functional layers, in particular on the basis of silver. Each of the metallic functional layers is disposed between two dielectric coatings. The coating includes at least two absorbent layers which absorb solar radiation in the visible part of the spectrum, which is disposed at least in two different dielectric coatings.

Abstract: 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, including two metallic functional layers, in particular based on silver. Each of the metallic functional layers is disposed between two dielectric coatings. The dielectric coating Di2 situated between the two functional layers includes at least one absorbent layer 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.
