New Intech Lens
Until now, tubular skylights only worked at their optimum level when the sun is higher in the sky: from 10.00 am to 2.00 p.m. in most instances. Tubular skylights' performance decreased dramatically in the early morning and late afternoon.

Light is still refracted during the early and later parts of the day
Flashing shown here is the 250mm diameter style
While Skytube already boasts high performance levels, including the patented Variable Pitch Adaptor that eliminates 'bends' in the light tube to simplify installation, The new optional Intech technology will offer homeowners a skylight that performs much longer than competitors' products.
In winter, the Skytube Intech provides up to twice the performance of conventional tubular skylights.
The price listed is for the 600mm shaft - see below for longer shaft lengths.
