VELUX Sun tunnels

Although not new to the VELUX product range, VELUX sun tunnels are sometimes over looked as an alternative to VELUX  Roof Windows.  Sun tunnels can be a cost effective way to allow natural daylight in to dark hallways, stairwells and windowless bathrooms. The cost savings over the installation of roof window can be significant. Their are two size available which allow the installation between the existing structural roof timbers.  There is no requirement fo the creation of a window well and associated costs. Sun tunnels are usually allowed under "permitted development" in Scotland and as there is no significant alteration there is usually no requirement for a building warrant. This cannot be said for the installation of roof windows. As  Suntunnels are available for both Flat roofs and pitched roofs with a range from  0° - 60° most roofs will be eleigble for installation.
