No, most window films will not work on Plexiglass or plastic windows. There is an application option where you can install a blister-free film over the Plexiglass and then install the window film over that. Regular window films will not work when installed directly on Plexiglass or plastic windows.
The Problem with Plexiglass and Window Film
Plexiglass, which some may know by the chemical name Poly(methyl methacrylate), and plastic both have the potential to outgas. Outgassing is when a gas that was trapped or absorbed in the material is spontaneously released. The problem with outgassing from a window with window film installed is that the gas is released between the plexiglass surface and the film. This can affect the adhesive bond between the two materials and create unsightly bubbles under the film. This will not only affect the appearance of your film, but also its performance.
In addition to issues with outgassing and bubbling, when window film is applied to plastic or Plexiglass, it can be very difficult to remove the film without causing damage to the surface of the window.
As is the case for any type of window film, regardless of window type, you will always want to have it professionally installed. Not only can you save yourself the headache, but installing window film incorrectly, or to the wrong surface (such as Plexiglass) can be a very costly mistake.
