Window Film basically comes in two forms and has two purposes:
1. Window tinting is usually done for either increased privacy, to keep out sunlight and heat out or to keep the warmth in. With advances in technology, window films are very durable and once correctly fitted almost invisible. The advantages are being realized by more and more people. In fact using any form of window tint in your home or business can actually save you a significant amount of money on your energy bills, particularly if you have very large windows. Window tint works by reducing the amount of heat loss during the winter and then also reducing the over heating from direct sunlight during the summer. In both cases you will not have to use either your heating or air conditioning quite as much. Though these savings may only be minimal, after a number of years they can certainly add up.
2. A Decorative window film, is basically an adhesive free transparent material that is applied to the interior of windows, in either a domestic or commercial building. A lot of people choose to use window films to brighten up their home windows, or a business may use them to advertise their name or certain products on shop front. Nowadays it is possible to get bespoke window films created toy your own design, or even have lettering stencilled onto the film.
