Developed by CPFilms, a subsidiary of Solutia, the EnerLogic Series is part of the Vista Window Film lineup of architectural window films. With a low-E coating, the window film adds 92% more insulating power to existing commercial and residential windows in each season. In summer, sunlight is reflected away from windows, and, in winter, radiant heat is directed back into the building. The film gives single-pane windows the same insulating properties as double-pane and double-pane windows the same as triple-pane. Its average payback is less than three years, and it is designed for both commercial and residential applications.
