Most window films contain metal which reflects light and reduces visibility.  The Prestige line of window films from 3M contain no metal, yet are very effective in blocking UV rays and solar energy.  An absence of metal also means no corrosion or loss of cell phone signal.

There are several things to consider before applying window films.  First, understand your climate and the orientation of your house or apartment.  If you live in a cold climate, apply film on the inside of northern and eastern-facing windows to keep heat in.  In warmer climates, apply film to southern and western-facing glass as a barrier against heat.

Besides saving on utility bills, 3M films reduce fading to interior furnishings, wall, and floor coverings by virtually eliminating UV rays.  And while heavy tint can actually lower your home’s value, 3M Prestige line of films are available either modestly tinted or clear.

3M window films lower energy consumption and saves money.  What’s not to like?
