A low emissivity glazing on a pane of glass, includes a set of thin layers formed by vacuum deposition assisted by magnetron, the set of thin layers including at least one metal layer reflecting infra-red rays between one or more dielectric layers located between the metal layer and the glass sheet, the metal layer being provided with a protective barrier coating, including a layer of titanium oxide or sub-oxide, deposited in a weakly oxidizing atmosphere at reduced pressure via a conducting titanium oxide cathode.

Low emissivity glazing

Low emissivity glazing which is an assembly of thin layers including at least one metal layer reflecting infrared rays between one or more dielectric layers located between the metal layer and the glass sheet and on the metal layer, the light transmission of one clear float glass sheet 4 mm thick coated with said layers being not less than 83%, the metal layer being selected such that the emissivity is not higher than 0.042.

Transparent substrate coated with a silver layer

A coated sheet for use in a laminated assembly and having a high level of luminous transmission and a low energy transmission includes a transparent substrate carrying a coating including two metal layers formed of silver or silver alloy and three layers of a transparent dielectric non-absorbent material, in the sequence, from the substrate: non-absorbent 1/metal 1/non-absorbent 2/metal 2/non-absorbent 3, wherein the two metal layers have a total geometrical thickness which ranges from 16.5 to 22 nm, wherein the non-absorbent 1 layer has an optical thickness which ranges from 50 to 56 nm, wherein the three layers of a transparent dielectric non-absorbent have a total optical thickness which ranges from 220 to 260 nm, and wherein the coated sheet has a thickness ratio of non-absorbent 2:nonabsorbent 1 which ranges from 2.1:1 to 2.8:1.

Coated substrate for transparent assembly with high selectivity

A coated substrate including a substrate; a stack of coating layers provided on the substrate composed of, in the sequence recited, (i) a first layer of dielectric material which is a composite layer including a sub-layer comprising a selectively absorbent material having a refractive index of at least 1.4, a spectral absorption index k.sub..lambda. of at least 0.4 in the range 380&lt;.lambda.&lt;450 nm and having a ratio of k.sub.380&lt;.lambda.&lt;450 nm /k.sub.650&lt;.lambda.760 nm &gt;2, (ii) a first layer of a metal selected the group consisting of silver, gold, copper and alloys of one or more thereof, and (iii) a second layer of dielectric material.
