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.
40% of the problem
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.
