Thin Films Reduce Solar Heat Gain

Rob Hamilton, President of the Window Film Association of Australia and New Zealand, comments, “While still relatively new, ceramic nanotechnology is an exciting development in the window film industry.” The industry is excited about nano-ceramic window films because they are spectrally selective, meaning they reject glare and block heat while providing visible light and optimum clarity. In addition to their heat control properties, the films are fade and corrosion free, outlasting other conventional films by more than 50%.
One compound commonly used in the manufacture of window film is Titanium and Nitrogen, TiN, an ideal ceramic for solar control. A precise, thin layer of the ceramic is deposited on polyester in a high tech sputtering process (traditional films use a dyeing and metalising process). The Nano-ceramic films are often more expensive than conventional alternatives, but there is no difference in the manufacturing times, and all methods adhere to the strict environmental regulations of the country of manufacture.
