The VELUX CVU Electric Glass Rooflight combines an electrically vented base unit with a curved glass top unit for a seamless glass-to-edge look. The curved top lets rainwater drain away even on 0° roofs, while the slim frame and invisible sash bring in maximum daylight, and you can choose standard double glazing or triple glazing for enhanced energy efficiency.
Why Choose the VELUX CVU Electric Glass Rooflight | Curved Glass | Rain Sensor?

Please note:
A complete rooflight consists of a base unit and a top unit supplied separately, so the total weight is the base unit plus the top unit.
Allow an additional clearance of typically 1 cm on the side designated for cable installation. The base unit should be installed with the rain sensor down the slope and the hinges up the slope.
