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.
