Fixed Flat Roof Skylights

The VELUX Fixed Flat Roof Skylight is designed for homes with flat or low-pitch roofs to transform and improve virtually any space with daylight. Topped with either CurveTech glass or a polycarbonate dome, its unique design lets in more daylight, easily drains rainwater, and stands out externally as a modern addition to roof surfaces.
