When choosing an armored door we often ask ourselves whether it is possible to insert glass elements without losing safety.

The arrangement of the glass can be carried out in different configurations inside the armored door, we therefore distinguish three different configurations:

Fenestration
In the case of windows, the glass is positioned inside the door, inside the door in the case of double doors or both. The geometric opportunities and the possibility of selecting different ones guarantee maximum flexibility

Fanlight
The glass for the fanlight is positioned above the door or double doors: the shape can range from rectangular to half-moon.

Sidelight
The glass in this case is positioned on the side of the door, positioned on a fixed, single or double door.

Choosing glass: providing light safely

Safety glass is tested using characteristic resistance tests, regulated by the UNI EN 356 standard ”Tests and classification of resistance against manual attack”.

The legislation classifies safety glass based on the resistance to actions due to external forces. Two categories of glass are defined through two different types of tests:
anti-vandalism glass
anti-burglary glass
The tests used have the aim of verifying the ability of the sheets to delay, for a limited period of time, the access of objects and/or people to a protected space.

The vandal resistance performance is classified by means of the hard body drop test. A steel sphere of approximately 100 mm in diameter and a mass of approximately 4.11 kg is used. This is dropped from different heights and all three specimens used in the test must prevent penetration by the impact body.

There are five classes for this type of test, from P1A to P5A, in ascending order of performance.
As regards burglary resistance, the test used is the so-called ax test, in which all three specimens used must require at least the minimum number of blows established to create an opening.
The ax head has a mass of approximately 2 kg and must be made of forged steel.
For this type of test there are three classes, from P6B to P8B, in ascending order of performance.

Mister Shut uses glass that guarantees burglar-proof, acoustic and thermal performance. The standard glass used by Mister Shut is P5A which offers high acoustic and thermal insulation (UG=1.1 W/m2K,…)
