Is window film better than tinted glass?

Can window film save on my energy bill?
Once installed Global window film helps reduce the amount of solar heat energy coming through a pane of glass. This makes it easier to cool a room or the interior of a car, resulting in lower energy consumption. The extent of savings will depend on the type of film selected and the geographic location where the film is used.

What is meant by "Curing" and how long does it take?
All window film installers use a special soapy solution during installation. It is normal for some of this solution to become trapped between the glass and the film, requiring time to "dry-out". The curing or dry-out time is necessary for window film adhesive to properly bond to the glass. How long it takes depends on factors such as the film type and climate during and after installation completion. Your professional installer will tell you what to expect.

What do I need to know about maintenance?
After the dry-out process is complete your window film will not need any special care. Cleaning window film can be done safely with mild soapy water and a soft cloth or soft paper towel. Do not use any rough or abrasive materials for cleaning the film side of the glass. Always use cloths that are free of contamination or dirt particles.
