Frequently Asked Questions


What is window film?

Window film is optical-grade polyester sheeting with colored dye and/or metal particles embedded into its surface. This reduces the transmission of solar heat, light, and ultraviolet rays through a pane of glass, simultaneously reducing glare.

How is window film applied to glass?

The film has a powerful adhesive on one side that is kept clean by a protective liner which is removed at time of installation. Professional installers completely clean and prep the glass prior to installation. Using a special mounting solution, squeegee and stainless cutting blades, they prepare, fit and secure the film to the glass.

Can window film be applied to any surface?

NO; window film is designed for application to smooth window glass only. It is not recommended for use on any unsmooth surfaces or polycarbonates.

To what extent can window film reduce heat?

Heat rejection properties of window films vary from one product to another. Some films can reject as much as 83 percent of total solar energy.

How long does window film last once applied to glass?

The life of window film depends on factors that include the application of the film, orientation of the window and geographic location. When properly installed, it is not uncommon for window film to remain attractive and effective for as long as 30 years or more.

What kind of warranty comes with window film?

Evolution Window Films provides limited lifetime warranty coverage for a number of our residential films. Other products are backed by varying degrees of warranty coverage, depending on the film and application. Ask your professional installer for a copy of the specific warranty for your film selection.

Is there a window film you can't see through?

Evolution Window Films carries the industry's finest Black Out film which completely blocks all light and obstructs visibility from both sides.

Why is window film a better choice than tinted glass?

Window Film provides numerous benefits including solar heat and ultraviolet rejection. They can be easily fitted to most existing glass which makes them less costly than replacing windows with tinted glass. They also help protect occupants from flying shards of broken glass in the event of accidental breakage.

Can window film stop fading of my furniture, artwork and other objects?

Window film is constructed with ultraviolet inhibitors embedded in the films adhesive which blocks up to 99 percent of the ultraviolet energy that is harmful to humans and damaging to fabrics and furnishings. However, ultraviolet energy is only one of the factors that contribute to fading. It is estimated that ultraviolet is responsible for roughly 40 to 60 percent of fading. Solar heat and light energy also contribute to fading, as does humidity, moisture, abuse and the quality of some dyes used in fabrics. Since these factors vary for different types of films and materials, the fade reduction benefit will also vary depending on the type of film selected, the quality of the products being protected and the environment.

Can window film save on my energy bill?

Once installed window film helps reduce the amount of solar heat energy coming through a pane of glass. This makes it easier to cool a room, 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.

Can window film be scratched during cleaning?

Proper care and cleaning is critical to maintaining the beautiful appearance of window film. All window film products are susceptible to scratching and damage if they are not properly maintained. To help prevent minor scratches that can occur with cleaning, all of our window films come standard with a durable, scratch-resistant coating. Still, it is important to follow the care and cleaning instructions provided by us to ensure a long service life from your window film product.

Does window film reduce the chance of glass breakage?

Standard solar control window films can help hold broken glass together in the event of accidental breakage. However, these films do not strengthen the glass enough to provide shatter-proofing, or reduce the chance of glass breakage.

How long does it take to install window film?

The amount of time it takes to install window film depends on the site of the application, access to the glass and the experience level of your selected installer. If you are concerned about the time frame, be sure to ask us for an estimate of installation time.

What is meant by "curing"?

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 of my window film?

After the dry-out process is complete your window film will not require any special care. Cleaning window film can be done safely with mild soapy water and a soft cloth/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.

Can I replace my existing window film with new film?

A major benefit of window film is that you can remove and replace it whenever you want. We would be happy to discuss this with you.
