Care Kool Solar Films are manufactured in the U.S.A. using the latest nano technology. This technology is applied through the multilayer-sputtering process, creating nano molecular metal to sputter unto the clear polyester film. This process creates a solar tint film that is able to have a high performance in heat rejection. Through this technology, Care Kool Solar Films not only managed to perform high heat rejection, but also infrared and UV rejection. This will ensure defection and discoloration are prevented during the warranty period.
