A coated glass pane comprising at least the following layers: a glass substrate and at least one absorbing layer based on at least one metal silicide and/or metal silicide nitride wherein the at least one absorbing layer is embedded between and contacts two layers based on an (oxi)nitride of Si and/or an (oxi)nitride of Al and/or alloys thereof.

Heat treatable coated glass pane

A process for producing a coated glass, the process comprising, a) providing a glass substrate, b) depositing a chemical vapour (CVD) deposited coating on at least one surface of the glass substrate to produce a CVD coated glass, and c) sputter depositing a further coating on the surface of the CVD coated glass, wherein the further coating comprises at least three reflective metal layers.

Method of coating glass

A coated glass pane comprising at least the following layers: a glass substrate; and at least one absorbing layer based on at least one metal silicide and/or metal silicide nitride wherein the at least one absorbing layer is embedded between and contacts two layers based on an (oxi) nitride of Si and/or an (oxi) nitride of Al and/or alloys thereof.

Flat glass composition comprising the following (expressed as percentages by weight): SiO60 75%; AlO0 5%; NaO 10 18%; KO 0 5.5%; CaO 0 5%; MgO 0-2%; SO0 1%; FeO(total iron)&#x3e;0.01%; TiO0-1% and one or both of: SrO 0-15%; BaO 0-15% with the proviso that the summed amount of SrO and BaO is greater than 4%. A preferred composition comprises: SiO65-74%; AlO0-3%; NaO 13 16%; KO 0-2%; CaO 1-4.9%; MgO 0-2%; SO0-1%; FeO(total iron)&#x3e;0.01%; TiO0 1%; BaO 4-10%; SrO 0-5%, wherein the summed amount of the alkaline earth metal constituents is in the range 10-13% and the summed amount of the alkali metal constituents is in the range 14-16%. The ferrous level of the glass may be greater than or equal to 28%, its performance in a thickness of 5 mm or less may be greater than or equal to 29 at LT&#x2267;70%, and greater than or equal to 27 at LT&#x2267;75%, and its liquidus temperature may be less than or equal to 980&#xb0; C.
