V-KOOL revolutionary technology was first developed for classified US aerospace and defense applications including the USAF radar-evading stealth bomber, as well as the US Space Agency NASA. It is a derivative of wavelength selection technologies which allow materials to be coated with the special optically coated materials which absorb, reflect and/or transmit specific ranges of electromagnetic radiation.

V-KOOL is produced using top 1% grade of optically-clear and durable polyester with a multi-layer of expensive rare metals such as gold, silver, indium oxide sputtered layer after layer on the polyester in a US$24 million vacuum sputtering machine. The rare metals and multilayer sputtering process creates the superior heat reflecting properties that block infra-red heat transmission by as high as 98%.

V-KOOL spectrally selective films are manufactured and processed at Southwall Technologies plant in USA and Germany.
