The VELUX flexible (TWF) and rigid (TWR) Sun Tunnels provide installation flexibility.
Rigid tunnels (TWR) are most suited to roof space with minimal obstructions. They have a highly reflective shaft to achieve maximum light output.
Flexible tunnels (TWF) 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.
