  • Patent number: 7534496
    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.

  • Patent number: 7521096
    Abstract: A coated article is provided which may be heat treated (e.g., thermally tempered) and/or heat bent in certain example 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 of or including silicon nitride and zinc oxide. It has been found that the use of such a tin oxide inclusive interlayer results in significantly improved bendability of the coated article in applications such as vehicle windshields with deep bends.

  • Publication number: 20090068447
    Abstract: An absorbing layer of a low-E coating is designed to cause the coating to have a more bluish color at normal and/or certain off-axis viewing angles. In certain example embodiments, the metallic or substantially metallic absorbing layer (e.g., NiCr) is located in the middle section of the layer stack and has been found to unexpectedly provide desirable bluish glass side reflective color for the coated article at certain off-axis viewing angles (e.g., at a 45 degree off-axis viewing angle). In certain example embodiments, the absorbing layer is provided between first and second nitride inclusive or based layers in order to reduce or prevent oxidation thereof during heat treatment thereby permitting predictable coloration to be achieved following the heat treatment. Coated articles according to certain example embodiments of this invention may be used in the context of insulating glass (IG) window units, vehicle windows, other types of windows, or in any other suitable application.

  • Patent number: 7462398
    Abstract: A coated article is provided that may be heat treated in certain example embodiments. A coating of the coated article includes a zinc oxide inclusive layer located over and contacting a contact layer that is in contact with an infrared (IR) reflecting layer of a material such as silver. It has been found that the use of such a zinc oxide inclusive layer results in improved thermal stability upon heat treatment, more neutral and/or desirable coloration, lower sheet resistance (Rs ), and/or lower emissivity.

  • Publication number: 20080220160
    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.

  • Patent number: 7419725
    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 layer 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.

  • Patent number: 7314668
    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.

  • Publication number: 20070163872
    Abstract: A sputter coated article is provided with improved mechanical durability (e.g., pre-HT scratch resistance) and/or thermal stability by sputtering at least one Ag inclusive layer in an atmosphere including at least O2 gas. For instance, in certain example embodiments an Ag inclusive target may be sputtered in an atmosphere including a combination of Ar and O2 gas. In certain embodiments, this enables the resulting AgOx infrared (IR) reflecting layer to better adhere to adjacent contact layer(s).
