Declaration of performance

Hundreds and thousands of customers test VELFAC windows every day. Throughout Europe, millions of windows have stood the test of time, but despite this track record, we still maintain a demanding testing programme to ensure our system continues to meet - and exceed - all necessary regulatory standards.

You can download a summary of the most recent tests from:

VELFAC windows have been tested by Europe's most rigorous standards agencies, which have analysed all aspects of window design and performance. The VELFAC system has received approval from:

  • Chiltern Dynamics and BM Trada, Buckinghamshire, United Kingdom
  • Vinci Technology, Bedfordshire, United Kingdom
  • CWCT, University of Bath, United Kingdom
  • SP Technical Research Institue of Sweden, Boraas, Sweden
  • Teknologisk Institut, Aarhus, Denmark (DTI)
  • DELTA, Aarhus, Denmark

In many cases we test special requirements for the qualities of our windows - child safety, fire safety and noise reduction are some of the areas we have tested.

Note: Individual test results refer to specific types and size of window - please refer to the individual test reports.
