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.

In an assembly of the character described, a frame, a pane of glass mounted in the frame and having inside and outside surfaces and an energy control sheet carried by the inside surface of the pane of glass, said energy control sheet comprising a sheet of substantially transparent flexible polymer thin film plastic material having first and second surfaces, an optically active substantially transparent adhesion promoting layer adherent to said second surface of said sheet, said adhesion promoting layer being substantially continuous, a substantially transparent metal layer adherent to said adhesion promoting layer and a protective layer adherent to said metal layer, said metal layer being formed of silver and having a thickness ranging from 60 to 200 Angstroms, said adhesion promoting layer and said protective layer being formed of zinc sulphide and having a thickness ranging from 300 to 500 Angstroms.
In an assembly of the character described, a frame, a plane of glass mounted in the frame and having inside and outside surfaces, an energy control sheet carried by the inside surface of the pane of glass, said energy control sheet comprising a sheet of substantially transparent flexible polymer thin film plastic material having first and second surfaces, an optically active substantially transparent adhesion promoting layer adherent to said second surface of said sheet, said adhesion promoting layer being substantially continuous, a substantially transparent metal layer adherent to said adhesion promoting layer and a protective layer adherent to said metal layer, said metal layer being formed of copper having a thickness ranging from 100 to 500 Angstroms, said adhesion promoting layer and said protective layer being formed of chromium and having a thickness ranging from 10 to 200 Angstroms.
In an assembly of the character described, a frame, first and second panes of glass carried by the frame and having a space therebetween and a selective energy control sheet disposed between the panes of glass, the selective energy control sheet comprising a sheet of substantially transparent flexible polymer thin film plastic material having first and second surfaces, an optically active substantially transparent adhesion promoting layer adherent to said second surface of said sheet, said adhesion promoting layer being substantially continuous, a substantially transparent metal layer adherent to said adhesion promoting layer and a protective layer adherent to said metal layer, said metal layer being formed of silver and having a thickness ranging from 60 to 200 Angstroms, said adhesion promoting layer and said protective layer being formed of zinc sulphide and having a thickness ranging from 300 to 500 Angstroms.
In an assembly of the character described, a frame, first and second panes of glass carried by the frame and having a space therebetween and a selective energy control sheet disposed between the panes of glass, the selective energy control sheet comprising a sheet of substantially transparent flexible polymer thin film plastic material having first and second surfaces, an optically active substantially transparent adhesion promoting layer adherent to said second surface of said sheet, said adhesion promoting layer being substantially continuous, a substantially transparent metal layer adherent to said adhesion promoting layer and a protective layer adherent to said metal layer, said metal layer being formed of copper having a thickness ranging from 100 to 500 Angstroms, said adhesion promoting layer and said protective layer being formed of chromium and having a thickness ranging from 10 to 200 Angstroms.
