Increase Privacy, Safety and Security It will help to hold together broken glass if it is shattered in an accident. However don't worry, it will not trap you in the car as it is very easy (and a lot safer) to push the glass OUTWARDS once it has broken. In contrast it is very hard to push it inwards, like a thief would, if they were trying to break into your vehicle. Window tinting provides an increased level of privacy from the prying eyes of thieves. Heat Reduction Up to a 60% heat reduction can be achieved compared to untreated glass. Window films will help your vehicle cool more rapidly, even after hours in the blazing sun by reflecting the unbearable heat out of your vehicle.
