How Sun Control Window Films & Window Tints Work

by Stopsun on August 8, 2012

San Diego County has sunny days the majority of the year and having 3M’s sun control window films applied to your windows can help with heat, glare, blocking the sun’s harmful UV rays, and also help with fading.  But how does Sun Control Window Films Work?

Without Sun Control Window Films

Windows are designed to be a barrier from exterior elements (i.e. wind, rain and snow) while providing a natural view of the outside world. When solar energy, the heat, light and UV Rays hits a glass window almost 90% of the energy is transmitted through.

When sun control window film is applied to glass, its properties incorporated within the film, act as a solar energy barrier either by absorbing part of the energy or reflecting a portion of the energy away from the glass.

Window film is basically a self-adhesive polyester film that is applied to the interior surface of glass. It’s used as a “retrofit” for existing glass on homes, businesses, and commercial buildings in order to upgrade solar control and safety. Solar radiation from the sun is divided into 3 components; visible light we can see, and infrared and ultraviolet rays which we can only feel. As solar radiation strikes a piece of glass, window film acts as a “sunscreen” to block harmful UV rays as well as regulates the levels of heat and light passing through the glass. The amount of heat and light rejected is all dependant on the type of window film selected.
