Fakro SFD-L Sun Tunnel with Flexible Tube and Flat Roof Flashing

Tunnel light with flexible SFD tube. SFD-_ with flexible light-reflecting tube. SFD-_/L with light-reflecting tube and natural lighting in the attic space. The built-in tunnel in the ceiling allows for convenient use of the space.

Approximately 10% higher heat transfer coefficient compared to the dome model of the light tunnel, integrated connection for faster installation of the light tunnel.

The light tunnel consists of a roof element, a flexible 2.1 m long lighting tube SLM, a ceiling frame, a prismatic light diffuser, and an installation kit.

FIXED LIGHT-REFLECTING TUBE - The tube is made of metallized polyester and reinforced with a metal rod, creating a durable and flexible tube that is ideal for installation in small distances in spaces where it is necessary to bypass structural obstacles. The maximum recommended length of the tube is 4 meters for light tunnels with a diameter of 350 mm and 6 meters for light tunnels with a diameter of 550 mm.

ROOF ELEMENT - It consists of a vacuum-impregnated wooden frame, connected to a 0.6 mm thick sheet metal aluminum ridge in RAL 7022 tone and a 3 mm thick, UV-resistant polycarbonate dome.

CEILING FRAME - The new ceiling frame is made of organic glass and equipped with a light-diffusing element. Its cover is made of effective matte white polystyrene. The ceiling elements of flat light tunnels, compared to light tunnels equipped with a dome, have a more rounded shape.
