Burglar-resistant glass from SILATEC.
Why the standard is not enough.

Burglar-proof glass is usually tested according to the European norm EN 356. But this standard is not enough. Why? Think about it: have you ever seen a burglar who proceeds exactly according to the standard? We haven’t in 30 years. And we experience a burglary attempt about every two to three days, which we successfully repel. Of course, burglar-resistant glass from SILATEC complies with EN 356, and of course this standard is also a good first gauge. After all, it compares different products under the same conditions, and that’s OK. But standing up to real-life conditions and assuming the highest level of criminal energy demands much more.


Two burglars vs.
a jewelry store

SILATEC glass is tested by the best experts
in the world: the burglars themselves.

The best test instructions are provided by the burglars themselves – at least twice a week. Here ((link to the film)) you can see the original footage of a burglary attempt on one of our customers, a jeweler in Berlin. Another spectacular example is from Bulgari's headquarters in the Via Condotti in Rome, where two burglars crashed directly into our burglar-proof glass in the shop window with a tow truck ... It remained an attempt only, and left two criminals completely stunned and fleeing the scene. Certainly not an attack according to norm. But quite real. Because only here, in the unpredictable reality of crime, is it possible to see whether burglar-resistant glass truly deserves its name.

Burglar-proof glass from SILATEC means:
No chance for burglars.

Burglar-resistant glass from SILATEC puts up an invisible barrier against would-be intruders. Attackers have no chance, because our burglar-proof glazing is tested according to the strictest standards.
In the European standard EN 356, the requirements for burglar-resistant glass are clearly defined and standards and test procedures are precisely described: in the case of burglar proof glass, the resistance test is carried out by machine-guided attacks with an axe – with precision to the millimeter, always with the same impact force, with continuous regrinding of the axe edge. The examiners note the number of axe strokes required to make a 40x40 cm hole in the burglarproof glazing. This is the minimum opening an adult needs to climb through the pane. The higher the number of axe strokes, the higher the resistance class of the burglar-resistant glass according to EN 356. The spectrum ranges from 30 to 50 strokes for P6B glass to more than 70 strokes for P8B glass. Accordingly, burglarproof glass is classified in three resistance classes: P6B, P7B and P8B.

The intruder-resistant glazing –
in real life.

A standardized test must be carried out under constant conditions, simply to ensure the comparability of different break-proof glass types. In practice, the situation is quite different: Attackers practically never try to knock a 40x40cm opening into the attack-resistant glazing, as the test standard stipulates. In most cases, it remains a fist-sized hole, for example, to open a window or grab the accessible goods from a jewelry store. In reality, SILATEC’s burglar-resistant glass must fulfill its purpose even at extremely low or high temperatures – not only at room temperature, as specified in the standard. The test norm for break-proof glazing provides for an axe attack. In reality, however, there are numerous other burglary tools and often more than one attacker. As secure as SILATEC’s burglarproof glass is – the window frame must be just as sturdy! The standard tests how many axe blows the anti-burglary glazing can withstand. However, it does not check how long it can hold up. And it is precisely this time delay that is often the decisive factor.

Impact-resistant glazing –
zero protection!

The test procedure for impact-resistant glazing in accordance with EN 356 is comparatively gentle: the resistance classes P1A, P2A, P3A, P4A and P5A must withstand a steel ball weighing 4.11 kg, which falls several times onto the pane in the center. And this from different heights up to a maximum of nine meters. Glazing that can withstand this load is awarded the title of “impact-resistant glass.” A practical reference exists, for example, when the impact-resistant glazing has to withstand the stone throws of attackers. But the much harder stresses that security glass has to withstand far exceed the durability of impact-resistant glazing. This is why it must be expressly stated that impact-resistant glass offers NO protection against burglary!

FAQ's


How does a test according to EN 356 work?

In comparison, so-called impact-resistant glazing is tested according to EN 356 with a 4.11 kg steel ball, which hits the glass pane from different drop heights. The steel ball must not penetrate the pane. The resistance class is as follows: P1A, P2A, P3A, P4A, P5A glass and do not provide any burglary protection. Only resistance classes P6B, P7B and P8B glass provide burglary protection.
