Flexible sun tunnel TCF is used for installation in flat roofs which brings natural light into areas of the house where a flat-roof window installation is either not possible or not appropriate.
The frame is made of white PVC. Sash and diffuser are made of ASA plastic and the dome is made of transparant plastic (acrylic or polycarbonate).
The tunnel is made of flexible reflective material.
The VELUX sun tunnel for flat roof with flexible tunnel is the perfect choice for VELUX 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.
