One installation. A generation of use.
A VELUX roof window is produced using high-quality materials that ensure a long lifetime of use.* Our modular design philosophy makes maintenance, repairs, and upgrades easy, prolonging the product’s lifespan and supporting the circular economy.
*VELUX roof windows meet the highest quality standards and undergo extensive testing. This includes exposing the roof window to a year’s rainfall in just 15 minutes, and a mechanical test that opens and closes the window 25,000 times. That’s the equivalent of opening and closing the roof window, twice a day, for 34 years.
