How do 3M Sun Control 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 through the glass.
Typical colored or dyed window 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 are not as effective as reflective window films for reducing heat.
3M reflective Sun Control Window Films have been precision coated with metals and are designed to increase the solar energy reflection of the glass. These metallized films are range from moderate to excellent in solar performance (heat gain reduction).
All 3M Sun Control Films are made to be transparent and optically clear. The ultraviolet protection is built into the adhesive system to provide longevity to the film as well as provide UV protection for your home and office furnishings.
Most 3M Window Films are protected with our abrasion resistant coating that provides long-term durability and maintained appearance.
