Fakro SFF Flat Roof Light Tunnel Tubes

Fakro SFF Flat Roof Light Tunnel Tubes

The Fakro SFF Flat Roof Light Tunnel Tubes provide a practical way to introduce natural daylight into rooms where a traditional roof window or vertical window cannot be installed. By capturing sunlight at roof level and guiding it through the light-transmitting tube, the system helps bring natural illumination into darker areas of a building.

Bring Natural Daylight Into Difficult Spaces

The SFF is particularly useful in rooms where structural obstacles make conventional window installation difficult. Its flexible light-transmitting tube can be routed around obstacles, allowing daylight to reach spaces that may otherwise have limited access to natural light. Once sunlight enters the tunnel, it is reflected along the walls of the reflective tube and directed downwards towards the ceiling diffuser. The diffuser then distributes the natural light evenly throughout the room, helping to create a brighter and more welcoming interior.

Flexible and Reflective Tube Construction

The light tunnel combines a flexible light-transmitting section with a rigid aluminium tube. The rigid section features a reflective silver-based layer designed to reflect and guide daylight through the tunnel towards the diffuser. This combination offers flexibility during installation while helping to direct available sunlight into rooms where fitting a conventional window is not practical.

Suitable for Different Roof Coverings

The Fakro SFF is supplied with integrated flashing designed for use with a variety of roof coverings, including flat, corrugated, high-profile and slate materials. It is suitable for roof pitches from 15° to 60°, as well as flat roofs, providing flexibility for a range of roof configurations.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.
