Abstract
A heat reflecting fenestration composite is provided which includes in sequence: (a) a substantially transparent substrate; (b) a first outer dielectric layer; (c) an infrared reflecting metal layer; (d) a color correcting metal layer comprising a metal different from the infrared reflecting metal layer; (e) a protective metal layer comprising a metal different from the infrared reflecting metal layer and different from the color correcting layer; and (f) a second outer dielectric layer. The dielectric layers are typically indium oxide, indium zinc oxide, indium tin oxide or mixtures thereof. Preferably, the composite also includes additional layers of infrared reflecting metal layer, color correcting metal, protective metal and dielectric. Also preferably, the composite comprises a top layer of glass or transparent polymeric plastic. The infrared reflecting metal layer is typically silver, gold, copper or alloys thereof. The color correcting metal layer typically has a refractive index in the visible light range between about 0.6 and about 4 and has an extinction coefficient for light in the visible light range between about 1.5 and about 7. Metals such as chromium, cobalt, nickel…
