Abstract
Visually transparent, color corrected, infra-red reflecting films are disclosed for solar heat control. The films employ Fabry-Perot sandwich interference filters which are characterized by having three or more transparent layers of sputter-deposited metal such as silver directly contiguous with 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.
