How do 3M™ Sun Control All Season (LE) Window Films work?
3M™ Sun Control All Season Window Films, or Low E films work much in the same way as the Sun Control Window Films except that they offer an increased performance against cold weather heat loss. The patented constructions of these films enable the metal coating to reflect more of the interior room heat back into the room where it is needed. This improves comfort by reducing potential draft feelings near the window, and may also save on fuel costs, especially in commercial buildings. The LE films are also protected with our abrasion resistant coating for long term durability and maintained appearance.
