Window and curtain wall testing

Competence throughout Europe

Our core competencies also include the planning and execution of window and facade tests at renowned German and European testing institutes in accordance with the corresponding valid standards. In the product standards for windows (EN 14351) and façades (EN 13830), the verifiable product characteristics are described. The verification takes place in accordance to the respective test and classification standards. The majority of the tests are carried out at our in-house testing laboratory or on-site at the building. Furthermore, we collaborate with other experienced testing institutes.

The most important tests on windows and facades are:

  • air permeability
  • driving rain impermeability
  • pendulum impact test
  • resistance against wind pressure/suction
