VELUX Sun Tunnels TWF OK14, TWR OK14 and ZTR OK14
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.
