Two variants for different site conditions

Flexible version (TCF)
The flexible tunnel works well where structural obstacles beneath the roof or a lack of space prevent a straight vertical route. The flexible tube can bypass beams and services, and installation is quick and causes little disruption. It is a good choice for shorter distances between roof and ceiling or more difficult layouts.

Rigid version (TCR)
The rigid tunnel provides the best light transmission – light travels directly with fewer losses, making the room noticeably brighter. We recommend it where there is a clear, straight route from roof to ceiling, or where the distance is greater and you want to make the most of daylight.

Why choose a VELUX sun tunnel for a flat roof?

It brings light to places where a roof window is unsuitable or cannot be fitted,
improves comfort in lofts and areas beneath flat roofs,
reduces the need for artificial lighting during the day,
is attractive and discreet: indoors, you see only an elegant diffuser in the ceiling.

Practical accessories are also available, such as tunnel extensions and optional LED lighting for use after dark, allowing the whole arrangement to suit the specific layout of your home.

Selection and installation at Ambit

At Ambit, we choose a VELUX sun tunnel for flat roofs to suit your specific situation: the flat roof structure, room layout and the daylight effect you want. We will advise on whether a flexible or rigid tunnel is better and where to fit it so the light makes a real difference. If you wish, we can also survey and install it as a single service: watertight, attractive and in accordance with good roofing practice.
