<p>The invention is a heat reflecting transparent window cover having three layers. The composite has a substrate and a unique heat reflective stack disposed upon the substrate. The heat reflective stack disposed upon the substrate. The heat reflective stack has, in series, a first interference layer, an infrared reflecting metal layer, a second interference layer and a first non-intrared reflecting metal layer, a second interference lazer and a first non-infrared reflective layer. The first interference layer has an index of refraction which differs from the index of refreaction of the substrate by at least about 0.1. The first non-intrared reflective layer is composed of the material from one of the following groups of materials: (i) metals having an index of refraction greater that about 1.0 and an extinction coefficient greater than about 2.0, and (ii) non-metals having an index of refraction greater than about 0.5 and an extinction coefficient greater than about 0.5.</p> |
