Fakro SFZ Corrugated Roof Covering Light Tunnel Tubes

Fakro SFZ Corrugated Roof Covering Light Tunnel Tubes

The Fakro SFZ Corrugated Roof Covering Light Tunnel Tubes provide an effective way to bring natural daylight into rooms where a traditional roof window or vertical window cannot be installed. By guiding sunlight from the roof into the room below, the system can help make darker interior spaces feel brighter and more welcoming.

Bring Natural Light Into Hard-to-Reach Rooms

The SFZ Light Tunnel is particularly useful in areas where structural obstacles make conventional window installation difficult. The flexible light-transmitting tube can be positioned around obstacles, giving you greater flexibility when routing the tunnel between the roof and the ceiling. Sunlight enters the light tunnel and is reflected along the highly reflective inner surface. The daylight is then directed downwards towards the ceiling diffuser, which spreads the natural light evenly throughout the room.

Reflective Tube Construction

The system combines flexible and rigid light-transmitting sections to help guide daylight efficiently. The rigid section is manufactured from aluminium and features a reflective silver-based layer designed to reflect light along the tube. This construction helps direct available daylight towards the diffuser, making the SFZ a practical option for bringing natural illumination into areas that may otherwise depend heavily on artificial lighting.

Designed for Corrugated and Other Roof Coverings

The Fakro SFZ is supplied with integrated flashing designed to work with a range of roof coverings, including flat, corrugated, high-profile and slate roofing materials. The light tunnel is suitable for roof pitches from 15° to 60°, as well as flat roofs, providing flexibility for different building and 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.
