Flexible sun tunnel TWF is used for installation in pitched roofs and profiled roofing materials (tiles). It brings natural light into areas of the house where a VELUX roof window installation is either not possible or not appropriate.
The black frame with integrated flashing is made of polyurethane. Sash and diffuser unit are made of plastic.
The tunnel is made of flexible reflective material.
The VELUX sun tunnel with flexible tunnel is the perfect choice for sun tunnel installations when rigid tunnels cannot be used – i.e. when there is a beam or other obstacle between the roof and the ceiling.
Recommended for lengths between 0.4 m and 1.5 m for pitched roofs and 0.2 m and 0.9 m for flat roofs.
