Light tunnel for pitched roofs SRD-H

Discover natural light in rooms without windows that will transform the space in your home with the SRD-H light tunnel with the rigid light transmitting tube. The light tunnel is designed for roofs with high-profile roofing, up to 120 mm. It has an integrated flashing that ensures the tightness and stability of the entire structure. It is a functional solution that is perfect for rooms such as changing rooms, bathrooms, stairwells and corridors. Thanks to the use of a rigid light transmitting tube and a dome with high light transmission coefficient, it effectively illuminates interiors with natural light – even at long distances from the roof.

SRD-H - Descriptions[1]

Effective and efficient room lighting

The SRD-H light tunnel for pitched roofs with a rigid light transmitting tube uses an aluminium light tube coated with a highly reflective silver-based layer, which reflects up to 98% of daylight and transmits it into the building. The tube has sealing tapes that prevent light leakage and protect the interior against dirt accumulation, while improving lighting efficiency. The entire structure is airtight, durable and does not require frequent maintenance. The SRD-H light tunnel provides effective lighting for rooms far from the roof, while reducing the use of artificial lighting during the day. Three diameters are available – 250, 350 and 550 mm – allowing to choose the perfect solution for the size and function of the interior.

Comfort and aesthetics every day

Inside the room, the SRD-H light tunnel for pitched roofs with a rigid light transmitting tube is finished with a matt diffuser that gently and evenly distributes light. This ensures a pleasant, natural atmosphere without glare. This element creates an aesthetic, uniform whole with the ceiling. Additionally, it is possible to install the LSO light kit, which transforms the light tunnel into a traditional light source after dark. This makes the light tunnel a versatile solution, combining the function of daytime lighting with natural light and practical artificial lighting.

Dome

The outer element of the structure, made of UV-resistant and weather-resistant plastic, effectively protects the interior of the light tunnel. Its streamlined, rounded shape improves rainwater drainage and reduces dirt accumulation, which contributes to its long service life and low maintenance requirements. The transparent surface ensures uninterrupted access of sunlight to the light transmitting tube, which transfers light into the room. 

External cladding

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, perfectly matching contemporary roofing materials.

Light transmitting tube

The interior of the light tunnel is made of an aluminum tube, the surface of which is coated with a reflective silver-based layer. This allows it to reflect light intensely 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 installation sections. 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, which allows the system to be flexibly adapted to a specific interior arrangement.

Light diffuser

The final element of the light tunnel on the interior side is a matt cover, which forms a coherent unit 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 a constant supply of light throughout the day and can also be equipped with the LSO light kit, which takes over the function of standard lighting in the evening.

Characteristic features of light tunnels

Our products stand out for what truly matters. Discover the features that make them reliable and exceptional in everyday use.

Natural light where there are no windows

Light tunnels bring natural daylight into rooms without traditional windows, such as corridors, bathrooms, and dressing rooms. They make interiors brighter and more pleasant for everyday use.

Effective illumination

Applying specially designed light transmitting tubes allowed light tunnels to transmit daylight even several metres into the room. With this solution, high quality lighting can be maintained even in more complex roof structures.

Universal installation

Light tunnels are suitable for installation on various types of roofing, both flat and pitched. Their robust construction and carefully crafted details ensure reliable operation and aesthetic appeal for years to come.
