Velux Sun Tunnel Skylights
Flexible Sun Tunnel Skylights
If you need to install ducts around obstacles in the loft space, flexible sun tubes are the recommended option. These are the easiest to install due to the material’s maneuverability.
Rigid Sun Tunnel Skylights
Although they can be slightly maneuvered, rigid tubes are best suited for situations where there is a clear, unobstructed path from the roof to the ceiling.
