SECURITY WINDOW FILMS - DON'T ALLOW ROBBERS MAKE YOU PROBLEMS.

Definitions.

The problem: Glass can be the weak point of a house or other building – attacking the glass is a common tactic used by thieves to obtain entry into buildings. Glass is often not ‘Anti-Bandit’ resistant (the correct technical term is ‘Resistant to Manual Attack’).

The solution: Security of glass can be improved using modern, high performance, high durability window film. These micro-thin, high technology products provide a wide range of options with a variety of properties to meet your particular needs.

How glass is classified for security

The European ‘Anti-Bandit’ test standard EN 356 classifies security glass by simulating repeated attack on glass; it is based upon German technical research and standards. There are two types of attack test in EN 356: an impact test using a steel ball and a hammer & axe test for the most severe attacks. Security film cannot yet upgrade ordinary float glass to resist the most severe attacks, but can still provide significantly enhanced security.

EN 356 Class	Drop height of impactor	# of Impacts
P1A	1500 mm	3, in a triangle
P2A	3000 mm	3, in a triangle
P3A	6000 mm	3, in a triangle
P4A	9000 mm	3, in a triangle
P5A	9000 mm	9, in a triangle

Security glazing with window film

It may seem amazing that a micro-thin window film can be adhered to a piece of glass and transform it into security glazing, but this is exactly what happens. The film is intended to:

• Absorb some of the energy of each impact
• Hold shattered glass fragments together during the repeated impacts
• Provide a barrier to forced entry and, after breakage, a barrier to the weather

This thin, apparently ‘simple’ piece of plastic film modifies ordinary glass to security glass. The security film delays and deters thieves from entering your building through the glazing.
As shown in the picture above, ordinary plain 4 mm float glass plus a security film resists repeated attack by impact. The glass – which does not survive even the first impact and breaks into dangerous fragments – is protected by the security film. Security film can achieve EN 356 Class P1A or P2A; because security films are constantly being developed, by the time you read this it is possible that a security film on ordinary float glass can achieve EN 356 Class P3A or better. And by using combinations of more than one security film on float glass, or by using a security film on (for example) 6,4 mm laminated glass, ‘Anti-Bandit’ resistance to higher EN 356 classes may also be possible.

And here You can see what happen if there are NO WINDOW FILM.
