Detailed Product Description

Everyone knows that glass is a wonderful material, allowing light and energy to enhance our lives.  But sometimes glass can be a problem.

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).

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.

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 P3A; 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.
