Abstract: Light dispersive insulated glazing units are disclosed. The light dispersive insulated glazing units comprise two lites of glazing material, spaced apart from and opposing one another and a visible light dispersive film, such as a hologram or diffraction grating, interposed between confronting surfaces of the lites. Methods for producing these light dispersive insulated glazing units are disclosed, as well.

Abstract: A method for fabricating light dispersive insulated glazing units is provided. According to this method a substantially sealed integral unit comprising a pair of spaced glazing lites and a heat-shrinkable light dispersive film interposed between the glazing lites and spaced apart from the glazing lites is formed, the light dispersive film being fixed along at least two of its edges with respect to the edges of the glazing lites. The assembled structure is then subjected to a heat treatment for a time and at a temperature sufficient to heat shrink the light dispersive film and cause it to become taut and wrinkle-free.
