FAKRO Light Tunnels
When there is no opportunity to install roof or vertical windows in order to provide natural light, the light tunnel is an effective solution.
Thanks to the light tunnel, natural light gets into the building illuminating its interior. In the other rooms light tunnels can be an additional source of light.
The amount of light which enters the room via the light tunnels depends on the light intensity outside the building. The more light that illuminates the dome of the light tunnel, the more light is conveyed to the building interior.
There are two types of light tunnels available: SRT with rigid light transmitting tube and SLT with flexible light transmitting tube. Flashings enable installation of light tunnels in nearly every roof covering and even in flat roofs.
