Solar insulating window film comprising a sheet of substantially transparent flexible polymer thin film plastic material having first and second surfaces. First, second and third layers are adherent to the first surface of the film. The second layer is formed of copper. The first layer is formed of a material which possesses substantially the same nobility as copper or is inert to copper. The first layer counting from the first surface is formed of a material selected from nickel and palladium and oxides and sulfides thereof. The third layer counting from the first surface is formed of a material selected from nickel, palladium and chromium and oxides and sulfides thereof.

Enhanced durability solar insulating window film and assembly using the

Flexible selective energy control sheet construction formed of a sheet of substantially transparent polymer thin film plastic material having first and second surfaces. A substantially transparent continuous adhesion promoting layer is adherent to the second surface of the sheet. A substantially transparent metal layer is adherent to the adhesion promoting layer and a protective layer is adherent to the metal layer. The metal layer is selected from the materials of copper and silver.
