A coating provides a high solar heat gain coefficient (SHGC) and a low overall heat transfer coefficient (U-value) to trap and retain solar heat. The coating and coated article are particularly useful for use in architectural transparencies in northern climates. The coating includes a first dielectric layer; a continuous metallic layer formed over at least a portion of the first dielectric layer, the metallic layer having a thickness less than 8 nm; a primer layer formed over at least a portion of the metallic layer; a second dielectric layer formed over at least a portion of the primer layer; and an overcoat formed over at least a portion of the second dielectric layer. When used on a No. 3 surface of a reference IGU, the coating provides a SHGC of greater than or equal to 0.6 and a U-value of less than or equal to 0.35.

A coated article includes a coating, such as a low emissivity (low-E) coating, supported by a substrate (e.g., glass substrate). The coating includes at least one dielectric layer including tin oxide that is doped with another metal(s). The coating may also include one or more infrared (IR) reflecting layer(s) of or including material such as silver or the like, for reflecting at least some IR radiation. In certain example embodiments, the coated article may be heat treated (e.g., thermally tempered, heat bent and/or heat strengthened). Coated articles according to certain example embodiments of this invention may be used in the context of windows, including monolithic windows for buildings, IG windows for buildings, etc.

A low emissivity coating 30 includes a plurality of phase adjustment layers 40, 50, 62; a first metal functional layer 46; and a second metal functional layer 58 located over and spaced from the first metal functional layer 48. A ratio of the geometric thickness of the first metal functional layer divided by the geometric thickness of the second metal functional layer is in the range of 0.6 to 1. The low emissivity coating 30 provides a reference IGU summer/day SHGC of at least 0.4 and a reference IGU winter/night U factor of no greater than 0.4 BTU/hr-ft-° F. (2.27 W/m2-K).

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 Sn.sub.xZn.sub.y with a ratio of 0.1≦x/y≦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.
