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 second coating arranged in register with said first coating, the second coating providing at least two interfaces which, with the mass of the second coating, form means to reflect and refract light therefrom to interfere with the observation of iridescence. The invention also encompasses 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.
