ballistic-resistant windows

the expert in ballistic-resistant windows

From a security perspective, windows are one of the most vulnerable elements of a building. This means it is particularly important to give careful consideration to windows when taking measures in the area of ballistic resistance. Why not contact aalbers|wico - the specialist in structural ballistic security! We manufacture, supply and install ballistic-resistant windows precisely in accordance with your specifications. If you wish, they can also be offered in combination with intruder-, blast- and fire-resistant properties.

tested in practice

The resistance value of our windows has not only been calculated on paper – it has been tested in practice too. At our own test centre we can see how our windows stand up to the most rigorous of tests. This centre is equipped with a ballistic test bunker - the only one of its kind in the Netherlands.


Our windows are based on the European standards EN 1522 and EN 1063, but we can also go one step further. If stipulated in the Schedule of Requirements, we can supply a window offering the actual level of resistance you need. The official standards form the starting point here, but the window undergoes further testing on the basis of additional criteria.

testing methods

We always determine the resistance class of our ballistic-resistant windows in practice. For this we employ the methods and tools described in standards EN 1522 and EN 1063: a mechanical firing mechanism, temperature measurement, shots in a triangle with a certain distance between impacts and a chronograph.

resistance classes

The resistance class of ballistic-resistant windows is defined on the basis of a number of factors: the type of ammunition that is used, the type of weapon, the velocity of the shots fired, the distance at which they are fired and the number of shots discharged.
