Disclosed is a transparent panel capable of transmitting a desired proportion of visible radiation while reflecting a large proportion of incident solar radiation, and a method of preparing same, by sputtering an iron, nickel and chromium alloy to obtain a transparent metal film, and reactively sputtering the same or a similar alloy in the presence of oxygen. In one preferred embodiment, the metal film lies between the substrate and the metal oxide film which provides a continuous protective overlayer. In another preferred embodiment, the metal oxide film lies between the substrate and the metal film. The use of such panels can materially reduce the energy required for summer air conditioning when used for glazing in a building, vehicle or other structure.
