A material includes a transparent substrate coated with a stack of thin layers successively including, starting from the substrate, an alternation of three silver-based functional metal layers of increasing thickness and of four dielectric coatings denoted, starting from the substrate, M1, M2, M3 and M4, wherein each dielectric coating includes at least one high-index dielectric layer, the refractive index of which is at least 2.15 and the optical thickness of which is greater than 20 nm.

Material provided with a stack having thermal properties

A substrate is coated on one face with a thin-films stack having reflection properties in the infrared and/or in solar radiation including a single metallic functional layer, based on silver or on a metal alloy containing silver, and two antireflection coatings. The coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflection coatings. At least one of the antireflection coatings includes an intermediate layer including zinc oxide ZnOwith 0.05&#x3c;x&#x3c;0.3 and having a physical thickness of between 0.5 nm and 20 nm, or between 2.5 nm and 10 nm.

Substrate provided with a stack having thermal properties and a superstoichiometric intermediate layer

A substrate is coated on one face with a thin-films stack having reflection properties in the infrared and/or in solar radiation including at least one metallic functional layer, based on silver or on a metal alloy containing silver, and at least two antireflection coatings. The coatings each include at least one dielectric layer. The functional layer is positioned between the two antireflection coatings. The stack also includes a terminal layer which is the layer of the stack which is furthest from the face. The terminal layer is a metallic layer consisting of zinc and tin, made of SnZnwith a ratio of 0.1&#x2264;x/y&#x2264;2.4 and having a physical thickness of between 0.5 nm and 5.0 nm excluding these values, or even between 0.6 nm and 2.7 nm excluding these values.

Substrate provided with a stack having thermal properties and a metallic terminal layer

A substrate is coated on one face with a thin-film multilayer including at least one metal functional film based on silver or made of silver having a thickness e of between 7 nm and 20 nm inclusive of these values, and two antireflection coatings each including at least one antireflection film. The functional film is placed between the two antireflection coatings. The multilayer includes an upper discontinuous metal film having a thickness e' of between 0.5 nm and 5 nm inclusive of these values. The upper discontinuous metal film is located above the only or last metal functional film as counted starting from the face.
