Window Film FAQs

Window film helps combat the problems of fading, glare and damage to furniture. Most importantly, it helps make occupants feel more comfortable in the room.

Fading is primarily caused by a combination of 4 main components:
• visible light (glare) 25%
• heat 25%
• ultraviolet light 40%
• miscellaneous 10% (how you maintain home – heating/cooling, humidity, cleaning, etc..)

No. films will maintain the natural colors of your interior spaces. With less need for draperies, curtains, blinds, and shades, rooms may actually brighten significantly.

Yes. Up to 75% of the heat can be rejected by using window film. You need not be afraid of installing beautiful windows for fear of too much heat.

Most films are installed on the interior glass surface. This helps to protect the film from the exterior elements and prolong the service life. Some films are applied to the exterior surface when the interior surface cannot be accessed or glass type prohibits a typical installation.

Not really. While not quite as hard as glass, films are extremely scratch-resistant and may be cleaned with common household cleaners, non-abrasive paper towels, or cotton cleaning cloths. Caution should be exercised to prevent extreme gouging by hard, sharp, metallic objects.

The correct film will not cause your windows to break. Not all films can be used on all glass types however. Manufacturers have guidelines that need to be followed to ensure the glass will not break because of the film. There are some instances (about 1 in 750) where after the film is installed, glass breakage does occur. This is typically attributed to weak or defective glass that is hidden by the frame. In the event of breakage there is warranty coverage for the glass and the window will be re-filmed at no cost to the consumer.

Low grade window film whose mounting adhesive and dye components have broken down turn purple and bubble. Great Lakes Films uses stable and more advanced materials that do not discolor over time. It seems that only poor quality films are noticed, and high quality, professional installations go unnoticed, perceived as mere “factory-tinted glass.

Professionally installed window film comes with a residential lifetime warranty against cracking, peeling, adhesive failure or demetallizing.. Commercial warranty is up to 15 years. A service life of 15-20+ years is common.
