VELUX CFU & ISU Fixed Curved Roof Rooflight (Package)

The VELUX CFU & ISU Fixed Curved Roof Rooflight Package is a premium daylighting solution designed to bring natural light, energy efficiency, and modern style to flat or low-pitched roofs.

The fixed (non-opening) design provides outstanding thermal insulation and noise reduction, keeping interiors bright, comfortable, and energy-efficient all year round. Built with toughened outer glass and a laminated inner pane, the rooflight ensures long-term durability and safety. Its frameless internal design offers a minimalist aesthetic, while the flush-to-roof exterior enhances both modern homes and commercial buildings.
