Intura SunTube light tunnel for pitched roof type 35
A light tunnel is a system that uses reflection to allow daylight into a building. The advantage of this system is that only a small roof opening is required, compared to a skylight, for example.
The Intura SunTube light tunnel has a crystal glass dome that allows more light to enter than direct daylight. The dome is self-cleaning, does not yellow and algae or dirt will not adhere to it, so there will be no loss of light over the years.
