Abstract

This disclosure describes transparent glass window structures of the type bearing a coating of infra-red reflective material which is advantageously less than about 0.85 microns in thickness and wherein the observance of iridescence resulting from such a reflective coating is markedly reduced by provision of a very thin coating system beneath said infra-red reflective coating. The thin coating system forms means to reflect and refract light to interfere with the observation of iridescence. A particular advantage of the invention is the ability of the thin coating system to be coated in a fraction of time presently required to coat anti-iridescent interlayers of the prior art.
