Features:

• Flat roof light tunnels make it possible to illuminate with natural light all rooms under flat roofs. 
• Solution based on proven design of the type C flat roof window with a dome to ensure high durability and tightness.  
• Application of light tunnels allows daylight to rooms under flat roofs. In other rooms light tunnels can constitute an additional light source, enhancing the user's comfort and save energy.  
• Base of the light tunnel is filled inside with insulation material to secure excellent thermal insulation performance. 
• The base is made of recycled material, therefore the product is eco-friendly. 
• The light tunnel carries daylight via the light transmitting tube. Sunlight is reflected from the walls of the tube and is directed downwards to the diffuser. The diffuser which is fitted in the ceiling evenly distributes natural light, illuminating the room.  
• The light tunnel consists of installation frame, specially profiled aluminium cover and dome made of stabilized polycarbonate.

  - SRF - the light tunnel with rigid light transmitting tube with a length of 61cm. The tube can be extended using a special SRM extension kit.  
  - SFF - the light tunnel with flexible light transmitting tube which allows to bypass potential structural obstacles. The tube length is 210cm. 
• Light tunnels are suitable for roofs with pitches between 0° – 15°.
