Abstract:
A solar control film having low visible light transmittance and low visible light reflectance comprising:a first sheet of transparent substrate material having deposited thereon a solar-load-reduction (SLR) film for preferentially reducing infrared light energy transmitted through said SLR film, said SLR film comprising a film stack on a first surface of said first sheet, said film stack including at least a first dielectric film proximate to said first sheet, a first metal film, a second dielectric film, a second metal film, and a third dielectric film;a second sheet of transparent substrate material having deposited thereon a transparent film of metal effective to partially block light transmittance and to have a low visible light reflectance; andan optically massive layer located between said first and second transparent substrates.
