Velux Rigid Tunnel For Pitched Roof TWR/TLR

twr/tlr

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°

Product features:

  1. Recommended for tunnel lengths from 0.9 to 6 m between the roof and ceiling.
  2. 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.
  3. Can be extended to distances up to 6 m.
  4. Rigid tunnels has a diameter of either 35 cm or 25 cm.
  5. Super reflective coating along with interior of the tunnel provides a 98% internal reflection rate.
  6. An easy-to-assemble diffuser comes complete with a frosted polycarbonate insulating frame.
  7. Roof module is with 4 mm toughened glass and a removable sash. The glass is with clear and clean coating on the outside.
