FAQs

  What is the origin of safety film?

Safety film was developed in the early 1970s for the British government for use in the UK, Ireland and Europe, as a protective device to lessen injuries as a result of random terrorist bombing activities. Shock waves caused by such bombs would break nearby glass windows causing thousand of jagged pieces of glass to be hurled in a deadly fashion, creating serious human injuries and loss of life, and substantial property damage.

  What is glass fragment retention or anti shatter film?

These are two names that the US Government give to what is referred to generally as safety film. These names were developed by the US army corps of engineers to describe the nature of safety film and its ability to hold glass together in the event it is broken.

  How is safety film made?

Safety film is manufactured from single or multiple layers of tough, durable polyester film laminated together in a variety of constructions. One side of the film is coated with an extremely powerful adhesive formula that is applied to the interior surface of the glass, whilst the exterior (room facing) side is protected with a special scratch-resistant coating.

  How is safety film used?

In addition to its original use as a protective device against flying or falling glass from bomb blasts, safety film is useful in protecting against the perils of nature such as earthquakes, hurricanes and other severe windstorms. Safety film also provides security against industrial explosions and crime such as burglary, forced entry, rioting, looting and vandalism. Equally important, safety film can provide protection against accidental glass breakage from thrown objects, or from children and adults walking into glass doors and windows. Reports of serious glass-related injuries in the U.S. can exceed 150,000 annually.

  How does safety film protect against hurricanes and severe wind storms?

Hurricanes and severe windstorms generate large quantities of airborne debris that can easily break the glass in windows and doors. The potential danger for the home or buildings' inhabitants from flying glass is significant. Similarly, room interiors can sustain extensive wind, water and contamination damage (openings must be boarded up quickly at great cost). Safety film can lessen and may prevent a glazing system failure. In many cases, the broken glass will remain intact on the film within its frame.

  How does safety film protect against earthquakes?

The swaying motions caused by earthquakes can create tremendous stress on buildings and glazing systems. This stress can cause glass in doors and windows to implode, sending lethal shards of glass flying through the air. Based on Safety Film testing at the Naval Civil Engineering Laboratory, Port Hueneme, California, an issue of The Earthquake Research Institute Newsletter published by Cal State Sacramento stated that: “The holding property of the film/adhesive (system) prevents glass fragments from becoming hazardous free flying missiles”.

  How does safety film protect against industrial explosions and terrorist bombings?

The benefits of safety film against the perils of blasts in industrial explosions or from terrorism are well documented. Shock waves from an explosion have a far-reaching impact. For example, in the Oklahoma City bombing most windows within a 10-block radius of the blast were shattered. Safety film can greatly reduce the potential for injuries and property damage from flying and falling glass during such occurrences.

  How does safety film protect against burglary and forced entry?

Studies by the US Small Business Administration indicate that 64% of all commercial burglaries involve the breaking of glass in windows of doors. Intruders use an array of tools or weapons to gain entry: pipes, crowbars, baseball bats, axes, bricks, rocks, etc. Through its ability to offer significant resistance to attempts of penetration, safety film provides a level of protection and security. It is also an excellent deterrent to smash and grab activities. Unlike shutters, Safety film also offers the advantage of “after-hours” viewing of goods, 24 hour protection, as well as saving the bother of daily lowering and raising of the shutters. Furthermore Safety Film is maintenance free.
