Fakro SRF Flat Roof Light Tunnel Tubes

Fakro SRF Flat Roof Light Tunnel Tubes

The Fakro SRF Flat Roof Light Tunnel Tubes offer a practical way to bring natural daylight into rooms where a conventional roof window or vertical window cannot be installed. By capturing sunlight at roof level and directing it through the light-transmitting tube, the system helps brighten darker interior spaces naturally.

Bring Natural Daylight Into Difficult Spaces

The SRF is particularly useful for rooms where structural obstacles make traditional window installation difficult. Its flexible light-transmitting tube can be routed around obstacles, making it easier to create a suitable path between the roof and the ceiling. 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 spreads the natural light evenly throughout the room, helping to create a brighter and more welcoming space.

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 provides flexibility during installation while helping to direct available sunlight into rooms that may otherwise have limited access to natural daylight.

Suitable for Different Roof Coverings

The Fakro SRF is supplied with integrated flashing designed for a range of roof coverings, including flat, corrugated, high-profile and slate materials. The system is suitable for roof pitches from 15° to 60°, as well as flat roofs, making it a versatile option for different 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.
