Quality is a major priority at VELUX and we devote extensive resources to testing, quality control and market testing to ensure that our products meet all quality requirements.
In our test department, products are continuously exposed to a variety of tests as an integral part of our efforts to develop and improve our products.
We expose our products to extremes of climates and expect them to function perfectly in constant daily use, year-in, year-out. We encourage our customers to expect the very best and back our production with fair guarantees.
All VELUX Roof Windows are now CE marked. To obtian copies of the CE certifcates for individual roof windows, see our CE Marking
