How do 3M™ Window Films work?
3M™ Sun Control Films are designed to reduce the amount of solar heat transmission through window glass by increasing the solar reflection (not necessarily visible reflection) and solar absorption of glass. Typical colored or dyed films work primarily through increased absorption. The color absorbs the solar energy at the glass, thus reducing the direct transmission into the room. These films only offer marginal performance when compared to reflective films. Reflective films are films that have been precision coated with metals. These metallic films are designed to increase the solar energy reflection of the glass and some of the absorption. 3M™ Sun Control reflective films range from moderate to excellent in solar performance (heat gain reduction). 3M™ Sun Control Films are protected with our patented Abrasion Resistant coating for long term durability and maintained appearance.
