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 coloured or dyed films work primarily through increased absorption. The colour absorbs the solar energy at the glass, thus reducing the direct transmission into the room. These films are not as effective as reflective films for reducing heat.
Reflective films are films that have been precision coated with metals. These metalized films are designed to increase the solar energy reflection of the glass. 3M reflective films 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.
