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.

Glazing comprising a functional coating and an absorbing element

A material includes one or more transparent substrates including two main surfaces, of which one of the surfaces of one of the substrates is coated with a functional coating capable of controlling solar radiation, the material including an absorbent layer for colorimetric adjustment of which the average absorption peak is centered between 500 and 555 nm and of which the full width at half maximum is less than 50 nm. The solar glazing has an improved aesthetic appearance without overly affecting thermal performance.

Glazing comprising a functional coating and an absorbent element for colorimetric adjustment

A computer implemented methods for estimating at least one quality function of a given layered coating on a transparent substrate allows to predict at least one non in-process measured quality function of a given layered coating on a transparent substrate from an in-process measured quality function which can be acquired on the coated substrate as deposited at any location, preferably at the end of a coating process. The method allows to get rid of in-process real-time continuous measurements of quality functions of the coated transparent substrate and real-time monitoring of coating process parameters.

Method for estimating a quality function of a mono- or multi-layered coated transparent substrate

A material includes a transparent substrate coated on one face with a stack of thin layers successively including, from the face, an alternation of four functional metal layers based on silver and five dielectric coatings. The physical thickness Eaof the first functional layer Agis less than the physical thickness Eaof the second functional layer Ag, with 0.60<Ea/Ea<0.90. The physical thickness Eaof the first functional layer Agis such that 8.00≤Ea≤13.00 nm. The physical thickness Eaof the first functional layer Agis less than the physical thickness Eaof the third functional layer Ag, with 0.60<Ea/Ea<0.90. The physical thickness Eaof the first functional layer Agis less than the physical thickness Eaof the fourth functional layer Ag, with 0.60<Ea/Ea<0.90.

A composite pane includes an outer pane, an inner pane, and a thermoplastic intermediate layer. The composite pane has, between the outer and inner panes, a solar protection coating that substantially reflects or absorbs rays outside the visible spectrum of solar radiation. The solar protection coating includes starting from the outer pane, a layer sequence of first dielectric module (M), first silver layer (Ag), second dielectric module (M), second silver layer (Ag), third dielectric module (M), third dielectric module (M), third silver layer (Ag), fourth dielectric module (M), wherein the silver layers (Ag, Ag, Ag) have a layer thickness relative to one another of Ag/Ag>1 and Ag/Ag>1, and the dielectric modules (M, M, M, M) have a relative layer thickness of M/M>1, M/M>1, and M/M>1.

Additionally, absorbent material is present between the face of the substrate and the first functional layer in a total thickness such that 0.0&#x3c;Abs1&#x2264;0.5 nm and absorbent material is present above the third functional layer, in a total thickness Abs4 such that 0.0&#x3c;Abs4&#x2264;0.5 nm.
