VELUX recommend rigid sun tunnels for maximum light. The recommended tunnel length for a rigid sun tunnel is between 0.9m and 6m. (1.7m supplied, additional length made up with ZTR extension pieces).
The new Velux sun tunnel diffuser pane comes with EdgeGlow technology, a ring of clear glass that ensures a greater spread of light throughout the room.

Flexible sun tunnels are recommended in cases where a rigid installation would be more difficult due to an obstacle in the loft space.

Please note this sun tunnel is not supplied with BFX collars but these are available separately - please call us on: 01752 692760 if you would like a quotation for these products.
