MULTILAYER HEAT-REFLECTING COMPOSITE FILMS AND GLAZING PRODUCTS CONTAINING THE SAME

摘要

Visually transparent, preferably color corrected, infra-red reflecting films aredisclosed for solar heat control. The films employ Fabry-Perot sandwich interference filters which are characterized by having two or more transparent layers of sputter-deposited metal such as silver separated by dielectric spacer layers and optionally boundary layers. Methods for producing these materials by sputtering techniques as well as glazing materials incorporating these films are disclosed, as well. In preferred embodiments, these films are laminated into glazing structures.
