High-performance heat-reflective films having a metallic silver layer bounded by two dielectric layers are disclosed. The thickness of the layers is selected to insure high levels of heat rejection but relatively high levels of light transmission together with a substantial level of color neutrality.

Low transmission heat-reflective glazing materials

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.

Color-corrected heat-reflecting composite films and glazing products

Bronze-grey films for window glazing structures are disclosed. The subject bronze-grey films are characterized by having a layer of reactive-sputtered titanium suboxide of controlled composition between the bronze-grey metal layer and the plastic sheet which makes up the substrate of the film. The process by which these films can be made is also disclosed. These films offer superior resistance to failure by delamination.

Bronze-grey glazing film and window made therefrom

Apparatus for sputter depositing a layer of metal onto a laterally extended substrate includes a substrate support, a deposition station, a downstream sensing assembly and a computerized controller. The deposition station includes a cathode and anodes extending the width of the substrate. Gas supply is provided to each of a plurality of zones through a common distribution chamber with a plurality of inlets which in combination cover the width of the substrate on which a thin film layer is to be deposited. The gas flow is directed through each anode into the plasma region and is individually controlled for each zone. The downstream sensing assembly includes, for each zone, a four-point contact assembly usign four electrically conductive wheels. Two of the wheels are used to apply current to the thin film and two are used to sense the resistance of it. This information is fed into the computer for use in controlling the gas flow into the deposition station, by zone.

Apparatus for obtaining transverse uniformity during thin film

Visually transparent, infra-red reflecting films are disclosed 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 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.
