A transparent substrate provided with a stack of thin layers includes successively, from the substrate, an alternating arrangement of at least three functional metal layers and four antireflective coatings, each antireflective coating including at least one dielectric layer; the thicknesses and the nature of the different layers being adapted for the production of new solar protection glazing, to be tempered, having high thermal performance (S of approximately 2.1 for LT of the order of 60%) and a neutral color, the colors thereof being stable at an angle.

Substrate provided with a stack having thermal properties

A material includes one or more transparent substrates comprising two main faces, wherein one of the faces of one of the substrates is coated with a functional coating which can have an effect on solar radiation and/or infrared radiation, and a face not coated with the functional coating of one of the substrates includes a reflective color-adjustment coating comprising at least one dielectric layer including a reflective dielectric layer with a thickness of between 2 and 100 nm, all the dielectric layers of the reflective color-adjustment coating have a thickness of less than 100 nm.

Glazing comprising a functional coating and a color adjustment coating

A material includes a transparent substrate coated with a stack of thin layers successively including an alternation of three silver-based functional metal layers and of four dielectric coatings so that each functional metal layer is positioned between two dielectric coatings. Absorbent material is present between the first functional layer and the second functional layer, in a total thickness Abs2 such that 1.0&#x2264;Abs2&#x2264;5.0 nm and/or absorbent material is present between the second functional layer and the third functional layer, in a total thickness Abs3 such that 1.0&#x2264;Abs3&#x2264;5.0 nm. 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.
