3M security films are clear, single-layer polyester film and are applied to the inside of a glass door or window. If the glass were to break, it would break in place without being spread all over the floor or ground.
A building’s most vulnerable part is its glazing. Windows, while architecturally necessary, expose building occupants to certain dangers. Burglars gain access to offices through windows and glass doors. A detonated terrorist bomb will cause nearby glass to implode at high velocities in tiny shards. Flying debris from hurricanes can smash through a window and cause harm. 3M Safety & Security Window Film reduces these dangers.
