Ultra-violet Light, commonly referred to as UV light is in the low end of the nanometer range of measured light. The colours you see above represent the full spectrum of visible light, but UV light has such small wavelengths it is not visible to the naked eye.

Although it is a small factor in the overall measurement of total solar energy and doesn’t contribute to solar energy we feel as heat, it affects us in many ways. Even though it isn’t part of the spectrum that we feel or really see, it can be very harmful to humans as well as man-made and natural materials.

To effectively control fading it is important to control not only the UV light but to control some amount of visible light and infrared heat. If you block out all of the UV light you are only blocking 40% of the cause of fading. If you blocked all the ultra-violet, visible and near infrared you would block out 90% of the cause of fading but be in the dark. In comparison, if you controlled all the UV and 50% of visible light and infrared you would control 65% of the cause of fading.

When applied to existing glass advanced solar window films reject 99% of the sun’s UV rays. This is accomplished by utilizing UV-treated polyesters and coatings as well as UV absorbers in our adhesives, therefore protecting the window film itself and providing filtered light to enter and pass through the window.

While window film reduces fading from exterior sunlight it does not completely eliminate fading, as no window film does. However, by choosing the right window film for the situation, you can greatly reduce harmful solar rays and prolong the appearance and value of furnishings, fabrics, and finishes.
