No security film is burglar-proof or bullet-proof; they are a deterrent. Films are designed to make the glass more shatter resistant and may slow the projectile down but not to prevent penetration after several attempts. Various film/glass combinations may achieve a low level ballistic rating.

3M security window films are a low-profile, high performance measure of security in the battle against “smash and grab” crime. If a thief tries to break the glass with any tool or brick, the glass will break, but the film will hold it in place. The thief now must make a choice- continue to attack the window, try another window, or move on. Time is short and noise has to be avoided, they frequently select an easier target. However, a professional thief determined to gain entry, will eventually get in.

In violent weather, these laminates may have significant safety and security value. They can reduce the risk of injury from flying shards of broken glass and possibly help prevent debris and water penetration through the window, depending on the severity of the storm, type of glass, framing system, size and velocity of objects.

In an earthquake, these films can reduce the risk of serious injury from flying shards of broken glass and possibly prevent glass from falling out of a home or building. Again, much may depend upon the severity of the quake, the type and size of glass and framing system.

3M Security laminates were the first in the market in the 1970’s; originally developed to address the international concerns and needs for improving safety and security against terrorist acts of bombings. 3M security laminates can significantly reduce the risk of serious injury from flying shards of glass due to blasts.
