The Sky Tunnel is the ideal, energy saving solution to bring light into light commercial buildings or large residential homes. The Sky Tunnel has a 2m flexi tube that makes it easily installed into almost any ceiling space.


Flexi-tube™ is a tubing system that can be used in certain applications up to 3M in length. With 86% reflectivity, Flexi-tube™ is a cost effective alternative to Rigid98 Tube providing adequate light when applied in suitable applications.


Installation of a Sky Tunnel™ with Flexi-tube™ is very easy as the flexibility allows the installation of the roof parts and ceiling parts to be off centre, so avoiding obstructions in the attic space is simple.

Suitable for most types of roofing

The Sky Tunnel can be installed onto almost any type of roof, including tile (pictured right) or profiled steel (pictured above). The Sky Tunnel comes with everything you need for an easy installation.

Acrylic dome
