All films block a minimum of 95 percent UV, and it is very simple whenever they mix in the UV inhibitor for higher quality films. What they have done is they have impregnated a layer of film with UV inhibitors as well. That is basically what they are designed to do. Whenever the film is attached to the glass it absorbs that UV, so it does not come through the window. Whenever people think about fading, a lot of people think that UV is the only cause of fading. In reality, it only accounts for about 40 percent of the fade. The films that I carry, they block anywhere from 99-99.9 percent of the UV. So we are blocking the majority of that 40 percent fading aspect. Whenever we are talking with clients, we discuss the causes.


Twenty-five percent of your fade is caused by light and 25 percent is caused by heat. With window films there is just no way to stopping fading all together. The remaining 10 percent of the fading is called the miscellaneous, which I call uncontrollable interior lighting. It generates UV, which generates fade. If you look at a museum, a modern day museum, you rarely see any windows because they don't want outdoor damage. They have special diffusers to block out the UV to protect everything, and that's why we have done older museums, with window films to protect all that from coming through.
