VELUX Flex Sun Tunnel for flat roofs TCF.


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.

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


  • Recommended for tunnel lengths from 0.2 to 0.9 m between the roof and ceiling.
  • The 1-meter long, super reflective, flexible tunnel has a diameter of 35 cm.
  • Easy to assemble.
  • An easy-to-assemble diffuser comes complete with a frosted polycarbonate insulating frame.
  • Roof module in PVC and dome comes in both acrylic and polycarbonate.
