SKU: TWR 0K14 2010 Categories: , Tags: , , ,


The VELUX TWR Rigid Sun Tunnel, has a low profile design and can provide up to 3 times more daylight than the Flexible Sun Tunnel. Rigid tunnels are best used when there is an unobstructed path from roof to ceiling and for longer tunnel lengths.

It’s ideal for ceiling to roof connections that do not exceed 6.0 metres in length. The TWR Sun Tunnel has a new improved design, Flexi Loc that reduces both the installation time and tube assembly.

Ideal for flooding natural light into small areas such as walk-in robes, hallways, corridors or spaces where it’s not possible to install a traditional skylight.

The VELUX TWR includes an integrated polyurethane flashing system for tiles or corrugated roof. Further details available from your No.1 Roofing store.
