There are a lot of benefits to having window film installed on your windows: you can protect your furniture, art, floors, etc. from fading; you can become more "green" and save energy with less of a need to run air conditioners to cool your home or office; you can make a burglar's job more difficult by making your windows tougher to enter through; you can increase safety and keep the elements outside by holding glass together if a window were to break. These are just a few of the benefits of having window film installed on your glass and all of these will Save You Money!
Typically the money saved through energy savings alone will pay for the cost of window film. The money saved by protecting things like floors and furniture just makes having film on your windows even more beneficial. You almost can't afford not to have film.
