The VELUX curved glass roof window is the elegant daylighting solution for flat and lightly pitched roofs. It features a modern and purist design with a frameless upper surface, unbroken lines, and carefully concealed fasteners. The unique curved outer pane is not only stylish, but also functionally designed to ensure the complete and efficient drainage of rainwater. The inner glass unit provides optimal thermal-insulation properties and can be combined with an awning blind and a light-dimming or -diffusing blind. The electrically operated version is equipped with a control system and a rain sensor.
