FAQs

Does window security film really work?

In short, yes! While there are many different types of window security film, they can certainly obstruct the view from the outside, protect from UV rays, and even prevent intruders. However, with security films designed to prevent smashing, it’s important to note that they are not foolproof. Someone could still break through; it will just be much more difficult than an unprotected window.

How thick should window security film be?

While it all depends on your needs, we’d recommend that your window security film be no thinner than four millimeters.

How do you put film on glass?

This varies based on the adhesion mechanism of the film. For static based films, you simply wash the window, spray a soap and water solution on the glass, and apply the film, flattening it out with a squeegee.
