VELUX Rigid Sun Tunnel for flat roofs TCR.


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.

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° .

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


  • Recommended for tunnel lengths from 0.8 to 6m between the roof and ceiling.
  • The 1.7m long rigid tunnel should be used when greater lengths- in combination with ZTR extension sections- are necessary and to ensure adequate daylight levels are obtained. It is supplied with 2 x 45 degree bends.
  • Can be extended to distances up to 6m.
  • Rigid tunnel has a diameter of 35cm
  • Super reflective coating along the interior of the tunnel provides a 98% internal reflection rate.
  • An easy-to-assemble diffuser comes complete with a frosted polycarbonate insulating frame.
  • Roof module in PVC and an acrylic dome.
