VELUX professional - VELUX sun tunnels for flat roofs with flex or rigid tunnels

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 flex tunnels and rigid tunnels provide installation flexibility. Flex tunnels can be used when the angle between the roof and the ceiling is too small for a rigid tunnel. Rigid tunnels deliver a straight shaft of light for when the ceiling is placed directly under the exterior window.


VELUX sun tunnels can be installed on flat roofs with a roof pitch between 0° - 15° (VELUX code: TCF/TCR). 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.
