Light tunnel for pitched roofs SRD-S
Natural light can completely transform any interior – even those where traditional windows cannot be installed. The SRD-S light tunnel for pitched roofs with a rigid light transmitting tube is designed for flat roofing with a thickness of 2×5 mm. It is perfect for corridors, changing rooms and bathrooms, effectively brightening the space with daylight, which has a positive effect on the well-being and comfort of everyday life of the household members. The dome of the light tunnel effectively drains rainwater, and its design increases the durability of the entire system – regardless of weather conditions.

Choose effective room lighting
The SRD-S light tunnel for pitched roofs uses a rigid light transmitting tube with a silver-based reflective coating that reflects light with an efficiency of up to 98%. The refined design allows significantly more light to reach the interior. The tube is equipped with sealing tapes that effectively eliminate light leakage, increasing light efficiency and protecting the interior from dirt accumulation. The design is highly airtight, durable and does not require regular maintenance. The light tunne; can effectively transfer light over a distance of up to 12 metres, making it an excellent choice for multi-storey buildings and commercial facilities.

Perfect solution for any time of day
In addition to providing daylight, the SRD-S light tunnel can function as a lamp. Simply install an additional SLO light kit to use it in the evening or at night. The new design of the ceiling section allows convenient access to the lamp from the inside, which simplifies installation and any necessart maintenance. It is a functional combination of two lighting systems that effectively enhances the building's comfort.

Dome
The transparent dome is the outer element of the light tunnel and is made of durable plastic that is resistant to UV rays, precipitation and temperature fluctuations. Its rounded shape facilitates quick water drainage and reduces dirt accumulation. This makes the structure durable and virtually maintenance-free. The dome effectively protects the interior of the light transmitting tube, ensuring an uninterrupted supply of natural 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 consists of an aluminium tube coated with a silver-based reflective layer that strongly reflects light, allowing up to 98% of sunlight to be redirected into the room. Thanks to the mirrored surface, even delicate light is effectively transported and precisely directed where it is most needed. This is particularly advantageous 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. The tube can be extended using SRM modules up to 12 m, which allows the system to be adapted to the individual requirements of a given interior.
Light diffuser
The light tunnel is finished on the interior side with a matt cover integrated into the ceiling, which ensures soft and even diffusion of daylight. Thanks to this, the room gains pleasant, natural lighting regardless of the angle of the sun's rays. The diffuser ensures a constant supply of light throughout the day, and for additional functionality, it is possible to install the SLO light kit, which serves as a traditional light source in the evening.
Characteristic features of light tunnels
