Available clear or tinted for solar control, safety window films have been shown to hold broken glass together after impact, preventing sharp shards and flying projectiles. The patented multi-layer tear-resistant qualities of 3M Safety & Security Film make the combination of film and glass much more difficult to break and break through than unprotected glass. This can delay intruders and give people up to two extra minutes to take cover or call for help. By keeping broken glass intact, safety window film also reduces injuries and saves time and money on clean-up.
