  • Patent number: 7081302
    Abstract: A coated article is provided which may be heat treated (e.g., thermally tempered) in certain instances. In certain example embodiments, an interlayer of or including a metal oxide such as tin oxide is provided under an infrared (IR) reflecting layer so as to be located between respective layers comprising silicon nitride and zinc oxide. It has been found that the use of such a tin oxide inclusive interlayer results in significantly improved mechanical durability, thermal stability and/or haze characteristics. In certain example embodiments, a zinc oxide inclusive layer is provide over an IR reflecting layer in order to improve thermal stability. A zirconium oxide overcoat may also be provided in certain example instances.

  • Publication number: 20060099428
    Abstract: A coated article is provided with at least one infrared (IR) reflecting layer. The IR reflecting layer may be of silver or the like. In certain example embodiments, a titanium oxide layer is provided over the IR reflecting layer, and it has been found that this surprisingly results in an IR reflecting layer with a lower specific resistivity (SR) thereby permitting thermal properties of the coated article to be improved.

  • Publication number: 20060046018
    Abstract: A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a low solar factor (SF) value, a high selectivity (Tvis/SF) value, substantially neutral color at normal and/or off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances. In certain example embodiments, a sub-oxide layer may be used as a contact layer under an infrared (IR) reflecting layer in order to permit low SF values, high selectivity, and good coloration to be achieved.

  • Publication number: 20060046073
    Abstract: A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a low solar factor (SF) value, a high selectivity (Tvis/SF) value, substantially neutral color at normal and/or off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances. In certain example embodiments, asymmetric IR reflecting layer thicknesses may be used (e.g., bottom IR reflecting layer thicker than the top IR reflecting layer), and/or different contact layers for the top/bottom IR reflecting layers may be used to help achieve a combination of low SF values, high selectivity, and good coloration at normal and/or off-axis viewing angles.

  • Publication number: 20060046074
    Abstract: A coated article is provided with a low-emissivity (low-E) layer stack for use in a window unit or the like. The layer stack, or coating, may permit the coated article to achieve one or more of a fairly low solar factor (SF) value, a high selectivity (Tvis/SF) value, substantially neutral color at normal and/or off-axis viewing angles, and/or low emissivity. When high selectivity values are achieved, there is provided a high ratio of visible transmission to SF, which is a desirable feature in certain example instances.

  • Publication number: 20060029816
    Abstract: A heat treatable coated article (e.g., vehicle windshield, IG unit, etc.) is provided with a dual-silver low-E coating. Before and/or after heat treatment (HT), the coating and/or coated article has a visible transmittance of at least 70%, more preferably at least 75%. Moreover, the coating and/or coated article is designed so as to have approximately the same color when viewed over a wide range of viewing angles. In certain embodiments, at least one contact layer (e.g., of or including NiCrOx) that contacts an infrared (IR) reflecting layer (e.g., Ag) is oxidation graded so that it progressively becomes less oxidized through its thickness as it nears the IR reflecting layer. In still other embodiments, a Si-rich silicon nitride layer(s) may be utilized to reduce haze.
