Velux


Quality, development and improvement are important keywords at VELUX®.
This is especially true in our test department, where products are
continuously exposed to all kinds of tests as an integral part of our
company’s efforts to develop and improve our products.
Our VELUX test facilities ensure that new products comply with regulations and market demands to technical performance. And they ensure that our products are able to withstand all the different climatic conditions that VELUX products are exposed to in the markets where they are sold.
Our test procedures include such aspects as air and water tightness in a test chamber and a weather simulator, mechanical tests, durability tests, U-value tests, sound insulation tests and visual inspection of the surface quality. These tests simulate the various weather conditions that will affect VELUX windows in the different climates where they are installed; for instance, heavy snowload, heat and cold, wind and rain and many years of use, including 25,000 opening and closing operations.
Our thorough internal tests are then followed by tests and approvals by internationally accredited laboratories to ensure that any new products have been tested in every detail before they are installed in peoples’ homes.
At our factories, each step of the process is carefully checked, including inspection of received components to ensure that they meet our specifications, for instance through continuous inspection of part components.
Random checks are made to continually test the product’s technical performance, including air and water tightness and the strength of corner sections.
And the finished products are tested to ensure that they meet the extensive functional demands and visual quality specified by VELUX.
