Abstract
Abstract 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.
