A building's most vulnerable part is its glazing. Windows, while architecturally necessary, expose building occupants to certain dangers. Burglars gain access to homes and 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.
3M security films are clear, invisible, and are applied to the inside of a glass door or window. If the glass were to break, it would most likely break in place without being spread all over the floor or ground.
Deterring Smash and Grab Crime
In the event of a bomb blast, the possibility of the entire glass pane being blown inward is greater after the installation of 3M window film. This is still safer than glass imploding in tiny shards. However, the use of an attachment system decreases this likelihood.
An attachment system's main purpose is to anchor the film and glass to the window's frame. There are several attachment systems – wet glaze and mechanical.
A wet glaze attachment system requires a bead of Dow 995 Structural Silicone Adhesive to be applied to the entire perimeter of the glass. In most cases, the window gasket is trimmed or eliminated and the caulk bead takes its place and provides the necessary insulation. This attachment system often goes unnoticed by observers.
A mechanical attachment system serves the same purpose but in a different fashion. The window film is installed in such a manner where extra material overlaps the window frame and is then fastened to the frame by a system of metal bars and screws.
3M Fragment Retention Films have been tested to Federal Government and GSA Security Criteria Standards. This testing showed that the threat of injury due to flying glass is greatly lowered after the installation of 3M window film.
Because 3M Safety & Security Window Films help to hold glass in place, building occupants are now safer. These films have been tested to Miami-Dade standards and have passed the small missile impact test.
