speaking, a building's must vulnerable part is its windows. Whether
it be the easiest point of unwanted entry, or the first to give out
during a bomb blast explosion / windstorm, glazed surfaces can expose
building occupants to high risk. 3M Safety and Security Window Film
helps minimize this threat by holding glass fragments in place.
A would-be burglar most often targets a door or window to gain entry
into a home or office. A quick “smash” to the glass allows the prospective
felon to “grab” valuables, thereby committing a “crime” to the victim
– hence the term “smash and grab crime”. 3M security film strengthens
glass by adding an invisible protective layer that holds broken glass
in place. A window that might otherwise take a robber five seconds to
break through might now take one minute. And since wasted time is a
criminal's worst enemy, that burglar may decide to burgle elsewhere.

Not only does 3M Safety and Security Window Film help deter smash and
grab crime, but the very same film helps to protect building occupants
from the effects of a terrorist's bomb or natural windstorm.
An explosion may cause nearby glass to implode in tiny shards at high
speeds which are lethal to building occupants. In fact, studies have
shown that flying glass shards is the number two cause of death during
a bomb blast – only behind the trampling effect where the floor above
collapses. 3M security film, or fragment retention film, another name
by which this product is known, helps to hold these tiny glass shards
in place, or at least reduce the speed and number of shards that implode.
In fact, fragment retention film was credited for saving many lives
during the September 11th terrorist attack on the Pentagon.
Buildings located in areas susceptible to hurricane damage are also
candidates for 3M's Safety and Security Window Films. Flying debris
caused by a windstorm can strike a building's windows at high speeds
and injure building occupants.
