Frequently Asked

How does security window film work?

Security window film is installed on the inside of existing glazing, forming a bond with glass, and helping to hold glass together after impact.  The glass, film and frame are held together by an attachment system.  Security window film basically works like a car windshield, holding together after repeated blows.

Is security window film bullet-proof or bullet-resistant?

No security window films are not bullet-proof or bullet-resistant, however, they are shatter-resistant and can protect people and buy time when it matters most.  Films are often rated by standards organizations like ANSI / CPSC Z97.1, UL 972, or the GSA TS01.

Can you put security film on top of window film?

You can install two layers of security window film on top of window film, but we don’t recommend it. If you install two layers of window film on top of each other, 3M will void the product warranty. If you are interested in added protection with benefits of solar film, you can install tinted security window film.

How long does the window film last?

The intended use and construction of a given window film will determine its warranty and life expectancy. The standard warranty range for commercial applications is 10-14 years, and most of our 3M Window Films easily outlast their warranty period.
