3M Safety and Security film help prevent break-in’s and if a break-in does, unfortunately, occur it can actually delay the intrusion, but how? Once the layer of film is installed on the glass, the extra layers strengthen the windows. Should someone try to break through the glass, 3M Safety and Security window films hold the glass in place even if it shatters. By keeping the glass intact it can actually delay entry by an additional 90 seconds. This may seem insignificant, however, when it comes to emergency situations – every single second counts. By pairing our window films with other security measures you’ll have a better theft deterrence and create a safer space.
