A material includes a transparent substrate coated with a stack of thin layers I including a lower coating including at least one absorbent layer, a single silver-based functional metal layer and an upper coating including at least one dielectric layer. The absorbent layer is separated from the substrate and from the functional layer by one or more dielectric layers. The material, once fitted in a double glazing, makes it possible to obtain a high selectivity, in particular of greater than 1.45, an interior and exterior light reflection of less than 25% and bluish hues in exterior reflection and in interior reflection.

Material comprising a single functional layer containing silver and an absorbent layer

A transparent substrate is provided, on a main face, with a stack of thin layers including at least one metallic functional layer having properties of reflection in the infrared region and/or in the solar radiation region, based on silver or on silver-containing metal alloy, and two antireflective coating. The antireflective coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflective coatings. Additionally, at least one nickel oxide NiO layer is located on and in contact with the functional layer starting with the substrate. A physical thickness of the nickel oxide NiO layer is at least 0.3 nm.

Substrate provided with a stack having thermal properties comprising at least one nickel oxide layer

A transparent substrate is provided, on a main face, with a stack of thin layers including at least one, metallic functional layer having properties of reflection in the infrared region and/or in the solar radiation region, based on silver or on silver-containing metal alloy, and two antireflective coatings. The antireflective coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflective coatings. At least one nickel oxide NiO layer is located under the functional layer in the direction of the substrate and/or above the functional layer, with interposition of at least one layer or of just one layer made of a different material between the or each nickel oxide NiO layer and the functional layer.
