No, 3M Safety and Security Window Films are not hurricane-proof, earthquake-proof, bullet-proof, bomb-proof, nor burglarproof. No films ever could be. They do, however, make the window glass more shatter-resistant. In the event of a wind storm, these films may have significant safety and security value. They can help 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 (and the type of glass, framing system, size and velocity of objects, and more).
In an earthquake, these films can help 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 (and the type of glass, framing system, and more, too).
These films are not designed to stop bullets. The consumer should be cautious of any film manufacturer claiming their product to be bullet proof or bullet resistant. In certain situations, 3M Safety and Security Window Films may be applied to bullet resistant glazing—glass that is already rated to stop a specific class of bullets—to serve as an anti spall layer to prevent slivers of glass (or “spall”) from projecting.
3M films were originally developed due to the international concerns and needs for improved safety and security against terrorist acts of bombings. These films can significantly reduce the risk of serious injury from flying shards of glass due to blasts; however, much depends upon the severity of the blast and the proximity of the window glass to the blast (and glass type, framing system, and more too). Due to their tear resistance, flexibility and energy absorbing and dissipation properties, certain 3M Ultra Safety and Security Window films work particularly well at mitigating blast hazards.
3M Safety and Security Window Films are a low-profile, easily implemented measure of security in the battle against ‘smash and grab’ crime. The tough, shatter-resistant qualities of the film can hold the window glass together even if a brick (or similar object) were actually to pass through the glass. With use of a 3M Impact Protection Attachment system, the intruder is forced to create an opening through the filmed glass to which to pass. The thief must now make a choice: continue to attack this window, try another window, or move on. Time is short, and often they move on. However, if they are determined to gain entry, they will get in. It is generally recommended that the property have proper alarm systems in addition to 3M Safety and Security Window Film.
