How window films work.

Arrows demonstrate how window films reduce the amount of solar heat transmitted through your home’s windows while letting in natural light.

The science of sun control.

By reducing the amount of heat gained through transmission of sunlight, 3M™ Window Films let in the natural light you love while rejecting heat and UV rays. Window films can help you lower energy costs, eliminate hot spots, reduce glare and protect your furnishings — all without affecting your view.

  • Reduce up to 78% of the sun’s heat
  • Evenly disperse natural light
  • Block up to 99% of harmful ultraviolet rays

As shown in two diagrams, some window films only protect homes when the sun is perpendicular to a window, but 3M™ Prestige Series Window Films perform best when the sun is high—also the hottest time of day.

The science of the 3M™ Prestige Series.

What sets our Prestige Series films apart is the precision with which light waves are controlled as they pass through or reflect off of hundreds of layers of film. Compared to other films, Prestige Series Window Films increase their performance at a faster rate as the sun’s angle increases. That means greater protection and comfort when you need it the most.

All window films are tested when the sun is perpendicular to the window. 3M™ Prestige Series Window Films are tested and perform best when the sun is high, at the hottest part of the day.
