SRD-Z

The durable external cladding of the light tunnel effectively protects its structure from water, wind and changing weather conditions. Made of corrosion‑resistant sheet metal, it features an integrated flashing that ensures a watertight connection with the roof surface without the need for additional mounting elements. The cladding, available in anthracite RAL 7016, grey‑brown RAL 7022 or black RAL 9005, highlights the modern appearance of the light tunnel, complementing contemporary roofing materials.

The interior of the light tunnel consists of an aluminium tube coated with a reflective silver-based layer. This allows it to intensely reflect light and effectively redirect up to 98% of sunlight into the room. The mirror coating also ensures that weaker daylight is effectively transferred and precisely distributed where it is most needed. This solution is ideal for longer or curved sections of the system. The length of the light transmitting tube is 210 cm for sizes 250 and 350 and 180 cm for size 550 due to the lack of SRK elbows in the set. Additionally, the tube can be extended using SRM modules up to 12 m, allowing for flexible adaptation to a specific interior arrangement.

The final element of the light tunnel on the interior side is a prismatic cover, which forms a coherent whole with the ceiling and is responsible for the gentle, even distribution of daylight. Thanks to its use, the interior is filled with natural, pleasant lighting regardless of the angle of the sun's rays. The diffuser ensures an even supply of light throughout the day and can also be equipped with the SLO light kit, which takes over the function of standard lighting in the evening.
