3M safety and security film bonds to existing glass, helping retain dangerous fragments if the pane breaks and making rapid access through the opening more difficult.
Film does not make glass unbreakable or guarantee against intrusion. When correctly specified—and paired with an appropriate attachment system where required—it can provide valuable additional time, deterrence and injury protection.
Best for: Entry doors, sidelights, ground-floor windows, large panes, children’s areas, storm-exposed glass and homes concerned about accidental breakage or forced entry.
