Can You Put Window Film on Double-Paned Windows? And Other Residential Window Film FAQs

April 4, 2025

When homeowners learn about the option of window film to cover large windows in their homes, as an alternative to window treatments or completely uncovered glass, they generally have questions. Those range from the general to the specific. To answer some of them, we’ve provided FAQs about residential window tinting and Tint World® window film products below:

How is the window film installed? Is it applied to the inside or the outside of the glass?

Trained installers apply the film to the inside of your windows. They carefully clean the glass and then begin the application. Once applied, they use a special tool to smooth any bubbles from the surface.

How long does it take window film to dry?

At first, you may see a milky or cloudy spot on the film. This is an expected part of the drying process, which can last anywhere from one to eight weeks.

Can I expect energy savings?

Yes. The application of Tint World’s residential window tinting reduces up to 85% of the sun’s solar heat, which can save your air conditioning from working overtime because of unnatural warming. Also, the film blocks more than 99% of harmful ultraviolet rays, helping to protect your furniture and your skin.

How long does the film last? And does it lose any UV protection over time?

If proper care is taken you should see benefits from the Tint World home window film for years to come. And although anomalies happen, in most cases the UV protection holds up well for the life of the film.

Does residential window film provide any privacy? How about security?

Most window films allow for little privacy when the environment inside is brighter than outside. However, Tint World does offer window film with patterns that can help distort any view from the outside. There is a line of safety and security window film that makes the glass stronger and provides impact resistance from most explosions, accidents, vandalism and break-ins.

Potential Benefits and Risks of Residential Window Film Installation

While the benefits are many, including energy savings, UV protection, glare reductions and some enhanced privacy and security, there are a few risks involved. The window film could have cloudy spots that will not go away, which alter their appearance. Natural light is reduced, prompting some homeowners to express concern about installing the film because of its effect on house plants. And while once installed the film requires little maintenance, homeowners still need to take care when cleaning it, and the film will eventually need to be replaced.
