How long has V-Kool been around?
V-Kool was first installed in the U.S. in 1991 and was originally invented as a specialty item for the U.S. government and was applied to the U.S. Military’s Stealth Bombers. Performance data was obtained using a Perkin-Elmer Lambda 9 Spectrophotometer in combination with the “Window 4.0 Fenestration Program” provided by the Windows and Daylighting group at the Lawrence Berkeley Laboratories, the world’s foremost window science group. No other spectrally selective window film has been around half this length of time.
