ABSTRACT:
Composite energy control sheet of the type wherein a transparent-reflective metal layer is coated on a self-supporting transparent polymeric foil and protectively covered with a transparent polymeric layer. The protective polymeric layer is chosen to transmit 80% or more of the normal room temperature radiant energy spectrum (about 4-40 micrometer wavelength) so that when the energy control sheet is positioned adjacent (but other than outside of) a glazing unit and oriented so that the protective layer does not contact any face of the glazing unit, heat loss from the room is significantly decreased and the cold weather performance of the sheet is greatly improved. Among the suitable polymers for the polymeric layer are polyethylene, polypropylene and polyacrylonitrile.
