Abstract

Solar control films containing a visible light-transmissive flexible support, a first nucleating oxide seed layer, a first metal layer, an organic spacing layer, a second nucleating oxide seed layer, a second metal layer and a polymeric protective layer. The thicknesses of the metal layers and spacing layer are such that the films are visible light-transmissive and infrared-reflective. The films have high visible light transmittance, high Reflected Energy and low Total Solar Heat Transmission.
