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.\n\n\u003ch3\u003eBring Natural Daylight Into Difficult Spaces\u003c\/h3\u003e\n\nThe 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.\n\nOnce 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.\n\n\u003ch3\u003eFlexible and Reflective Tube Construction\u003c\/h3\u003e\n\nThe 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.\n\nThis combination offers flexibility during installation while helping to direct available sunlight into rooms where fitting a conventional window is not practical.\n\n\u003ch3\u003eSuitable for Different Roof Coverings\u003c\/h3\u003e\n\nThe Fakro SFF is supplied with integrated flashing designed for use with a variety of roof coverings, including \u003cstrong\u003eflat, corrugated, high-profile and slate\u003c\/strong\u003e materials.\n\nIt is suitable for roof pitches from \u003cstrong\u003e15° to 60°\u003c\/strong\u003e, as well as flat roofs, providing flexibility for a range of roof configurations.\n\n\u003ch3\u003eAvailable Sizes\u003c\/h3\u003e\n\nThe Fakro SFF Flat Roof Light Tunnel Tubes are available in the following sizes:\n\n\u003cul\u003e \u003cli\u003e\u003cstrong\u003e350 x 2100mm\u003c\/strong\u003e\u003c\/li\u003e \u003cli\u003e\u003cstrong\u003e550 x 2100mm\u003c\/strong\u003e\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\n\u003cul\u003e \u003cli\u003eHelps bring natural daylight into rooms without suitable roof or vertical windows.\u003c\/li\u003e \u003cli\u003eFlexible light-transmitting tube can help bypass structural obstacles.\u003c\/li\u003e \u003cli\u003eRigid aluminium tube features a reflective silver-based layer.\u003c\/li\u003e \u003cli\u003eHelps reflect and direct sunlight towards the ceiling diffuser.\u003c\/li\u003e \u003cli\u003eCeiling diffuser distributes natural light evenly throughout the room.\u003c\/li\u003e \u003cli\u003eIntegrated flashing is suitable for flat, corrugated, high-profile and slate roof coverings.\u003c\/li\u003e \u003cli\u003eSuitable for roof pitches from 15° to 60° and flat roofs.\u003c\/li\u003e \u003cli\u003eAvailable in 350 x 2100mm and 550 x 2100mm sizes.\u003c\/li\u003e \u003c\/ul\u003e\n\n\u003ch3\u003eA Practical Daylight Solution\u003c\/h3\u003e\n\nThe Fakro SFF Light Tunnel provides an effective alternative when installing a conventional roof window is not practical.
