It’s a great success. At the beginning of this year Silber managed the test of their windows at the resistance-level 3. Now the company, out of the little town Mistelbach, is a very important player on the safety sector.
The test was carried out by the Holzforschung Austria after the European standard ENV 1627 and Ö-Standard B5338.

A very important point for this test was the increasing number of burglaries everywhere. Especially on the private sector flexibility and high optical standards are getting more and more important. Silber combines these points with a high safety level.

It was also a hard job for the tester to get through the window. Only the use of heavy tools made it possible for them – but not in the regular time.
