A window structure includes a metal layer that transmits microwave signals and reflects infrared signals. A microwave signal is a signal that has a frequency in the microwave spectrum of frequencies (a.k.a. the microwave frequency spectrum). The microwave frequency spectrum extends from 300 megahertz (MHz) to 300 gigahertz (GHz). An infrared signal is a signal that has a frequency in the infrared spectrum of frequencies (a.k.a. the infrared frequency spectrum, which extends from 300 GHz to 430 terahertz (THz)). The metal layer may be a discontinuous metal layer that's an electrically discontinuous metal layer and/or a physically discontinuous metal layer.

The radiation of the projector is predominantly p-polarised, and the windshield is provided with a reflective coating, which is suitable for reflecting p-polarised radiation. The reflective coating has exactly one electrically conductive layer and arranged one above and one below the electrically conductive layer are two dielectric layer sequences, each including n low-optical-refraction layers having an index of refraction less than 1.8 and (n+1) high-optical-refraction layers having an index of refraction greater than 1.8, arranged alternatingly in each case, wherein n is an integer greater than or equal to 1.

A low-E (low emissivity) coating includes a multilayer overcoat designed for reducing fingerprints. The multilayer overcoat includes a layer comprising an oxide of zirconium (e.g., ZrO.sub.2) sandwiched between and contacting first and second layers of or including silicon nitride (e.g., Si.sub.3N.sub.4, SiO.sub.xN.sub.y, SiZrO.sub.xN.sub.y, or the like). The uppermost layer comprising silicon nitride modifies the surface energy of the layer comprising the oxide of zirconium so as to make the uppermost surface of the coating more hydrophilic, thereby reducing or minimizing interaction between zirconium oxide and finger oil to reduce fingerprints on the uppermost surface of the coating.

A material includes a transparent substrate on the surface of which is deposited a stack of layers which itself includes a plurality of functional layers making it possible to influence the solar and/or infrared radiation capable of striking said surface. The material has high thermal performance qualities and also an attractive shiny surface appearance of neutral color.

A laminated body includes a transparent substrate having a laminated film. The laminated film includes a dielectric layer containing silicon nitride, a barrier layer composed of a single film or two or more films, and a metal layer containing silver. The barrier layer has a thickness of from 0.1 nm to 10 nm. Each film of the barrier layer includes a material having a crystal structure of a face-centered cubic structure with a lattice constant of from 3.5 to 4.2, a hexagonal close-packed structure with a lattice constant of from 2.6 to 3.3, a body-centered cubic structure with a lattice constant of from 2.9 to 3.2, or a tetragonal crystal with a lattice constant of from 2.9 to 4.4. The metal layer has a thickness of from 7 nm to 25 nm. An orientation index P of the metal layer falls within a range from 4.5 to 20.

Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.
