VELUX sun tunnels for pitched roofs

VELUX sun tunnels for pitched roofs are designed to provide natural light into corridors, stairwells, bathrooms and cupboards, under pitched 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 distance between the roof and the ceiling is too small or too great for a straight – or rigid – tunnel. Rigid tunnels deliver a straight shaft of light for when the ceiling is placed directly under the exterior window.


A VELUX sun tunnel can be installed in tiled roofs (TWF/TWR) or slated roofs (TLF/TLR). Sun tunnels for pitched roofs can be installed in roofs with 15°- 60° pitches, for flat roofs you’ll need a VELUX sun tunnel for flat roof.

A VELUX sun tunnel is easy to install, regardless of your roof type. For profile roofing, choose our black polyurethane frame and lead-free lower flashing.

Flex or rigid tunnels?

Rigid tunnels TWR/TLR

Product features: 
Rigid tunnels are recommended when there is a straight, unobstructed path from the roof to the ceiling

  • Recommended for tunnel lengths from 0.9 to 6 m
  • The 1.8 m 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 30° bends. Can be extended to distances up to 6 m.
  • Rigid tunnel has a diameter of either 35 cm or 25 cm.
  • Super reflective coating along the interior of the tunnel provides a 98% internal reflection rate.
  • An easy-to-assemble diffuser kit comes complete with a frosted acrylic insulating pane and a standard, white ceiling trim ring.
  • Integrated polyurethane flush frame with 4 mm toughened glass with clear and clean coating on the outside. Frame with integrated, grey aluminium, flush flashing for installation in flat roofing material and with black polyurethane flashing and non-lead bottom flashing section for installation in profiled roofing material. Sash in ASA (ABS plastic), 4 mm toughened glass and stay-clean coating on the outside.

Flex tunnels TWF/TLF

Product features:
Flex tunnels are recommended when installation around obstacles within the loft space is required, or if there is not a straight, unobstructed path from the roof to the ceiling.

 

  • Recommended for tunnel lengths from 0.4 to 1.5m. 
  • The 2-meter long, super reflective, flexible tunnel has a diameter of 35cm.
  • Easy to assemble.
  • The diffuser kit comes complete with a frosted acrylic insulating pane and a standard, white ceiling trim ring.
  • Integrated polyurethane flush frame with 4 mm toughened glass with clear and clean coating on the outside.
