General Info

Heat rejection films are normally applied to the interior of flat glass windows to reduce the amount of infrared, visible light, and ultraviolet (UV) radiation entering windows. Such films are usually dyed or metalized (which can be transparent to visible light) to convert incoming solar radiation to infrared radiation, which is then rejected back through the glass to the exterior. Modern window film technology has created Ceramic Window Film which are non-metallic and do not contain dyes that can result in discoloration. The ceramic and metallic window films usually cost 10?15 percent more than regular window film but can reduce energy transmission by as much as 80 percent. Ceramic window films cost slightly more but provide a substantial increase in blocking UV rays and ability to control heat transfer.
