P4A glass, P6B glass or P7B glass? - SILATEC

P4A glass, P6B glass or P8B glass?

We will be happy to explain the somewhat confusing terminology of DIN EN 356. There are 5 low security classes (orange and light blue) and 3 high (dark blue). Only those marked in dark blue offer effective burglary protection.

difference between
P4A glass and P6B glass


Impact resistance glazing

The 5 low classifications P1A glass, P2A glass, P3A glass, P4A glass & P5A glass prevent the glass pane being smashed in, e.g. with a stone. It does not offer traditional burglary protection. For that reason it is also called only "impact-resistant glazing"

Burglar resistance glazing

The 3 high resistance classes P6B glass, P7B glass & P8B glass offer burglary protection and are accordingly called burglar-resistant glass, P8B glass offering the highest level of burglary protection.

Test methods according to EN 356

The security difference between impact-resistant glass (P1A to P5A glass) and burglar-resistant glass (P6B, P7B, P8B glass) is extreme. The biggest difference is between P5A glass and P6B glass and can be compared to apples and pears - namely not at all.

Test methods according to EN 356

As the testing methods are very different: with impact-resistant glass (P1A to P5A glass), a heavy steel ball of around 4 kg is dropped several times on the glass from various heights. By contrast, burglar-resistant glass (P6B, P7B, P8B glass) is dealt with significantly more harshly: using an axe.

Of course,
Silatec safety glass also fulfils the highest resistance classes - and more.

By comparison: the structure of Silatec P6B glass

It generally comprises five different layers. In different thicknesses. A mix of highly transparent and extremely impact-resistant materials. The concept makes optimum use of the different mechanical properties. What you see in our video is not a trick, but rather our P6B panel. A wall made of glass.

The structure of P4A glass

The construction of P4A glass is surprisingly simple. Two glass panes with a wafer-thin plastic foil in the middle. That’s it. The film holds the glass fragments together even if they are shattered, preventing injuries. But burglary protection? No. Not with P4A glass.

Which burglar-proof (armored) glass (P4A - P5A - P6B - P8B) for which challenge?

Very simple: only P6B, P7B and P8B glass offer protection against burglary. The P1A, P2A, P3A, P4A and P5A classifications do not protect against forced entry. P6B to P8B armored glass is built to give offenders no chance of breaking and entering for as long as possible. It is ideal, for example, for villas, embassies or shop windows. In contrast, P1A to P5A glass is used as roof glazing or in stair railings.
