There are three types of window film. Non-reflective or dyed film that absorbs the sun’s energy—providing heat reduction for automobiles. Reflective or metalized film that both reflects and takes in solar energy for architectural applications. And nano-ceramic film, which utilizes molecular science to engineer nanoparticles (which measure 1 billionth of a meter) to identify and absorb vast amounts of infrared heat, practically all the UV radiation, and varying degrees of visible light
