"Armored glass is a composite made of several sheets of glass."
These are alternately layered with PVB plastic layers and firmly autoclaved together. In an emergency, this composite of hard glass and flexible plastic film holds back the projectile. The disc absorbs energy and distributes it over a large area.
Laminated safety glass is available in two versions.
The thickness of bullet proof glass varies depending on manufacturer, multi-hit capabilities and armouring level. To withstand the ballistic demands of the protection level EN1063 with a 90° shooting angle;
If, for example, the windshield is only shot at in the installed position, i.e. at a shallower angle that emits less penetration energy onto the armoured glass, thinner bullet proof glass can be used.
High quality armoured glazing shows an excellent grade of translucence and optical quality. Safety glass with high protection classification often show a magnifying effect and distortions at corners and edges. The proper sealing of the window edges is also a quality feature. Well-known manufacturers give guarantees against delamination.
