    Glass dome made of Bohemian crystal

    The sun tunnels Lightway Crystal are unique, thanks to the crystal dome. It is made of Bohemian crystal and it collects 30% more natural daylight that polycarbonate equivalents. It is resistant against aging even in intense U.V. light and weather conditions. The crystal and the design of the dome have an ability to collect daylight even when it is cloudy and it does not distort natural colours of daylight.

     The surface of the crystal is polished and hard, so smog or impurities do not stick to it, that’s why it needs almost no maintenance. The crystal dome does not turn yellow after a few years and imits the same light for decades.

     Optical attributes of the dome are well designated, so it keeps hi performance light collection even if it is cloudy. That’s why it provides great light through the sun tunnel the whole day.

     

    Thermal insulation element Blue Performance

    The insulation element Blue Performance prevents thermal leaks through the pipe from the interior in winter. On the other hand in the summer, it prevents interior overheating due to excessive temperature. Blue Performance prevents water condensation in the space of the pipe and following water splashing into the diffuser and the ceiling construction. It is easy to connect the light tube to insulation element Blue Performance and a dimmer.

    • prevents thermal leaks and emoluments

    • coefficient of thermal permeability U 0,6W/m2K

    • prevents water condensation in the pipe of sun tunnel

     

    High reflective light tube

    Inside of the Lightway tube there flows sunlight into the interior. The inside walls of the tube are created by extremely powerful mirrors with maximum light reflectivity.

     The inside reflective layer is made of silver and silicon oxide, which are fixed by chemical vapor deposition in a vacuum. The layer will not or peel it or be warped by changes of temperature and humidity.

     Connecting the light tube to the adjustable elbow, Blue Performance insulation and a dimmer is easy due to systematic connections, which is a standard part of package.

     Technical information:

    • reflection of reflexive layer of the pipe 99,8%

    • ray diffusion during reflection in 45 angle in pipe <6%

    • the basic material is aluminum, 99,7%

    • overall maximum distance of sun pipe is up to 80 meters, including 2 adjustable elbows 90° direction change of the conduit. The conduit of the tube can be vertical or horizontal without any effect on performance.

     The loss of light affected by tube lenght can be as little as:

    • within 10 meters 0,5%

    • more than 10 meters 0,7%

      

    Glass ceiling diffuser – light diffuser

    The glass diffuser spreads light through the room and it prevents direct glare of light in interior. It is made of glass, that’s why it doesn't turn yellow and it lets the sunlight through well without any loss on light intensity and any change on the color spectrum. The diffuser is already assembled with the tube of the length 200mm. It is easy to connect the light tube to isolation element Blue Performance and a dimmer.

     

    • it is made of sodium-potassium glass

    • does not turn yellow, does not change color spectrum

    • white color trim 


     

    It is possible to buy assembly kits with steam-tight and diffuse foil and additional LED light.
