Ceramic films are a relatively more recent option. The films consist of a thin ceramic layer bonded to an adhesive layer and a top coat for protection. The ceramic layer’s purpose is to darken the window and to reflect heat. It blocks out around 30-50% of light.
The type of film is more effective in blocking heat, it blocks light glare and UV rays and unlike the dyed films do, it rarely fades. The film is also suitable for in-glass antennae as it allows passage of radio signals. However, it is not as reflective as the metalized options. Finally, it is the most expensive type of vehicle window film.
