Natural light where you never thought possible

The VELUX Sun Tunnel has been designed to make installation quick and easy. Tube assembly is simple, so little time is spent in the roof cavity.

The VELUX flexible (TWF) and rigid (TWR) Sun Tunnels provide installation flexibility. Rigid tunnels are most suited to roof space with minimal obstructions. They have a highly reflective shaft to achieve maximum light output. Flexible tunnels can be used when obstructions in the roof cavity prevent the use of rigid sun Tunnels.

VELUX Sun Tunnels for pitched roofs are designed to provide natural light into corridors, stairwells, powder rooms and cupboards; where installation of a VELUX Skylight is not possible

Less Time in Attic

Roof module with removable sash ensures quick and easy installation from the outside. Drop the tunnel into place from the roof. There’s little need to enter the attic; the tunnel is easy to install in tight spaces where attic access is difficult.

Easy to Install & Clean

The VELUX Sun Tunnel is easier to install thanks to the threaded diffuser. When you’re finished, simply screw the diffuser into place. And, as an added bonus, it’s easier to clean as it can be unscrewed and cleaned as needed.
