The 3M Company obtained its first patent for window film in 1966. Since then, the company has developed an array of different window films, include Scotchtint and Scotchshield films. 3M window films darken windows to keep out the sun, making rooms easier to cool. The films can block up to 99 percent of harmful UV rays, protecting upholstery, wallpaper, carpets and furniture from fading. The films carry a ten year warranty for most applications and should be applied by window tint professionals.
