What is a SunTube, light tunnel or tubular skylight?
A SunTube, also known as a sun tunnel, light tunnel, or tubular skylight, is a high-performance daylighting system that channels sunlight from the roof into the interior of your building using a highly reflective tube. A clear dome on the roof collects sunlight throughout the day, which is then directed down through the reflective tunnel to a diffuser in the ceiling, spreading soft, natural light into the room.
Unlike traditional skylights, SunTubes are compact, flexible, and highly efficient—even in overcast conditions. They can be installed in almost any type of roof and require minimal structural changes.
Ecopower: Insulation for passive house performance
In addition to daylight, thermal performance matters. That’s why Intura offers the Ecopower insulation system—a high-efficiency upgrade for our SunTubes that ensures outstanding thermal insulation. This system is specially developed for use in low-energy and Passivhaus constructions, where airtightness and insulation are critical.
With Ecopower, our sun tunnels not only deliver beautiful natural light, but also meet the strict energy performance standards demanded by sustainable building practices.
