Window film is a self-adhesive polyester based film that is applied to the interior surface of flat glass. It is generally designed to reduce heat energy particularly to upgrade control of solar heat energy, reject UV radiation, as well as giving a building a certain type of aesthetic image. There are two types of window film – non-reflective or dyed films that primarily absorb solar energy, and reflective or metallized films that absorb as well as reflect solar energy.
