To understand the causes of fading, one needs to know a little about the makeup of sunlight.

Visible light and infrared heat are the other factors that contribute to fading, which is why effective film installations must harness all three sunlight elements. 

Visible Light - the part which enables us to see
Infrared Light - the part which we feel as heat
Infrared Light - the part which we feel as heat
Ultraviolet Light - we neither feel it nor see it, but it is the main factor in causing fabrics and furniture to fade

Ultraviolet absorbers are used to stop ultraviolet light at the film.  The type, amount and location of the absorber in the product determine the film's effectiveness in reducing fading.  Absorbers located in the adhesive instead of the film itself can be far less stable and enduring than those built into the film.

Our protective sheath bonds to windows with leading-edge clear, distortion-free adhesives. It lets glare-controlled sunlight pass through windows, while screening out heat and dangerous UV rays. By keeping room heat or air conditioning from escaping through windows, film helps to eliminate hot and cold spots within buildings.
