Providing even greater defense, metallized films act- ively reflect heat back towards the source, whether convection exists or not. The result is superior driving comfort and less load on the air conditioner. Many people associate window film with dark or faded purple tints that can be seen on some older vehicles. Actually, it's the lighter, higher performing films that provide the most protection and look the best on a car. The lower the percentage, the darker the film and the more privacy it offers.
Window films are also available with different performance features.
Economy window films are constructed of dyed or coated polyester and offer good UV and glare protection, but little heat re- jection or durability. These films offer the same benefits as economy films, but add an anti- scratch coating that keeps the film looking good longer. The best heat rejection available is from metallized films. Metallizing a film does not make it dark and shiny, but increases the active heat and rejection. The highest performing films available contain UV absorbers as well as metal to offer the maximum protection for both the vehicle and its passengers.
