blast-resistant windows

the expert in blast-resistant windows

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

tested in practice

We not only calculate the resistance level of our blast-resistant windows on paper - we test it in practice too, in our own test centre. Here we check whether the windows meet the required level of mechanical resistance (as described in the European standards) or the desired level of protection (as specified in the US GSA standard). 


Our windows are based on standards such as EN 13123, 13124 and 13541, the US GSA guidelines, and ISO 16933 and 16943, 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

In our test centre we can examine the resistance of a window under virtually all conditions using realistic tests. This is possible as we have the space to carry out open field tests and our facilities also include a shock tube.

resistance classes

During field tests and shock tube tests, the resistance class of a blast-resistant window is defined on the basis of various factors: these include the weight of the explosive, the distance at which the explosion takes place, the peak pressure, impulse and duration of the pulse of the explosion and whether there is any splintering.
