ABSTRACT:
This disclosure describes transparent glass window structures of the type bearing a first 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 first coating is markedly reduced by provision of a layer of continuously varying refractive index between the glass and the coating, such that the refractive index increases continuously from the glass to the first coating, thereby preventing the observation of iridescence. The invention also encompasses simple processes for providing such windows. A particular advantage of the invention is its efficacy with clear and lightly tinted glasses wherein the problem of iridescent color has had its greatest commercial impact.
