Products / Sky Tunnel XL2 Flexi Tube
Sky Tunnel XL2 Flexi Tube efficiently channels daylight into areas normally devoid of natural light. The Flexi-tube makes installation easy, requiring much less accuracy than with the rigid system. Sky Tunnel can be installed in less than two hours.
In domestic and smaller commercial applications the difference in light experienced between the flexible and rigid systems is quite small.

The Sky Tunnel System is made up of Three (3) Parts: Roof Parts: Includes all the parts you need for the roof already assembled and ready to install. The Dome is already fixed to the Breather Frame, the Tabs are already installed and all of this is already fixed to the flashing. There are different flashing to suit different roof types such as Tile, Slate, Metaldek, Custom Orb (CGI) etc Attic Parts: The parts that link the Roof & Ceiling. A choice of either Flexi-tube or Rigid98 Tube. Flexi-tube is more economical, easier to install and has very good efficiency. Rigid98 Tube has outstanding efficiency but takes longer to install and is more expensive. Flexi-tube is only recommended for lengths of 3m or less. Ceiling Parts: This includes all the parts you need for the ceiling. A ceiling frame/trim which is screwed to the ceiling, a ring for locking the flexi-tube into position and a double glazed diffuser system that magnetically fits to the ceiling frame. All the fixings you require for installing these parts are also included. |

The Sky Tunnel Flexi-tube System is made up of Two (2) Parts - Upper Ring and Flexi-tube. The Upper Ring is manufactured from Stainless Steel, and has slots cut into the top edge. These slots match up to lugs on the Breather Frame, and with a simple twist the ring is attached to the Roof Parts. The Flexi-tube is already attached to the Upper Ring, so the installation is very quick and simple. Once the roof parts are installed, with the Flexi-tube & Upper Ring already attached, the Flexi-tube is simply pulled through the ceiling frame and trimmed to an exact length. |
How do I work out what parts I need:
To work out your required length of Flexi-tube, measure from the ceiling to the top of the rafters and add 0.2m and chose the next longest length in the price list.
