VELUX sun tunnels for flat roofs

VELUX sun tunnels for flat roofs are designed to provide natural light into corridors, stairwells, bathrooms and cupboards, under flat roofs, where installation of a VELUX roof window is not possible.

The VELUX sun tunnels provide installation flexibility.  VELUX sun tunnels can be installed on flat roofs with a roof pitch between 0° - 15° (VELUX code: TCF). For a pitched roof, you’ll need a VELUX sun tunnel for pitched roof.

A VELUX sun tunnel is easy to install, regardless of your roof type.
