A building's most vulnerable part is its glazing. 

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

A homeowner's or retailer's worst fear is unwanted entry. Needing only a few seconds, burglars most often gain entry through a window or glass door. However, because 3M safety films hold glass in place, more time would be required for a robber to gain access into your home or office. Given that delay, the would-be thief is most likely to move to another target.

Terrorism

Safety and Security Window Film, otherwise known as Fragment Retention Film, was credited for saving many lives during the terrorist attack on the Pentagon on September 11, 2001. Glass nearby to an explosion may implode at high velocities in tiny shards, acting as daggers, and prove fatal to building occupants. In fact, this is the second highest cause of death in a terrorist attack next to the trampling effect whereby the floor above collapses.

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.

School Safety

A cost-effective way to help protect your schools. 3M™ Safety and Security Window Film has been incorporated into thousands of U.S. schools. Schools have chosen this solution because: It is more cost effective than replacing all windows and doors with laminated glass - It is easily applied, even over existing glazing - While it cannot stop intruders from entering school buildings, it does act as a deterrent, providing precious response time by slowing the intruder down.

Hurricanes

Coastal areas are subject to natural windstorms such as hurricanes and tornadoes. These high winds propel miscellaneous debris at high speeds. Many times this debris can come through a home's or office's window and threaten the safety of those inside.

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.
