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.

In a transparent, infrared reflecting composite film including a transparent metal layer-dielectric layer filter adhered to one side of a transparent support, the improvement comprising employing as the transparent metal layer-dielectric layer filter a visible light-transmitting infrared-reflecting Fabry-Perot interference filter which includes at least two separate discrete continuous sputter-deposited transparent metal layers separated from one another by a discrete continuous spacer layer of sputter-deposited inorganic metal oxide, compound or salt dielectric wherein each transparent metal layer is contiguous with and directly adherent to the adjacent spacer layer of dielectric without an intervening nucleation layer.
