Testing the durability and performance of our windows and doors is essential for the safety of our custoemrs.
At VELFAC, we test our windows and door units for:
Weather resistance: air tightness, water tightness and ability to withstand wind loads – from moderate wind all the way up to hurricane strength
Safety: Drop and impact test to prove strength and stability
At VELFAC we are one of the few companies which develop its own ironmongery, and these are carefully designed and manufactured to suit our windows and doors and to provide performance and durability.
All our windows are drop tested to make sure the window will not fall out from the facade should any ironmongery fail. As a result, this test proves that VELFAC windows are safe and secure.
We test the durability and longevity of our products by opening and closing the windows 20,000 times and the doors 50,000 times.

UK guidelines state that the noise level within a living area in a family home should not exceed 35dB.
The sound-reducing effect of the window depends on the glazing construction and the window size, sash, frame and joint sealing. Therefore, it is important that tests are conducted of the entire window element and not only the glazing.
VELFAC has a large selection of sound windows and can present sound reports in connection with specific cases. Here you will find the test results for a number of product series:
