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.

Substrate equipped with a multilayer comprising a partial metal film, glazing unit, use and process

The invention relates to a substrate () coated on one face () with a multilayer of thin films () with reflective properties in the infrared and/or in the solar radiation band comprising a single functional metal layer (), in particular of silver or of a metal alloy containing silver, and two dielectric coatings (), said coatings each comprising at least one dielectric layer (), said functional layer () being disposed between the two dielectric coatings (), said multilayer furthermore comprising a single absorbing layer (), characterized in that said absorbing layer () is a metal layer having a physical thickness in the range between 0.5 nm and 1.5 nm, or even between 0.6 nm and 1.2 nm and is situated directly on said face () and directly under a dielectric layer of nitride not comprising any oxygen.

Substrate having a multilayer with thermal properties and an absorbing layer

The invention relates to a transparent substrate provided with a thin-film multilayer comprising a metallic layer having infrared-reflection properties located between two, subjacent and superjacent, nonmetallic dielectric coatings, the superjacent dielectric coating comprising the sequence of thin layers deposited in the following order: The invention allows the solar factor of a multiple glazing unit to be increased, and an acceptable color, especially in transmission, which is in particular less green, even also less yellow, to be obtained for a multiple glazing unit.
