Fakro SRZ Rigid Sun Tunnel with Profiled Flashing

Flat light tunnel with fixed tube SR_.SR_ - with fixed light reflecting tube.SR_-L - with light reflecting tube and natural lighting in the attic. The built-in tunnel in the ceiling allows for convenient use of the space.

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

The SR_ light tunnel consists of a roof element, three 61 cm long lighting tubes SRM, an elbow SRK, a ceiling frame, a prismatic light diffuser, and an installation kit. The total length of all connected sections in a straight line is 2.1m (SR_ 550 - 1.8m).

FIXED LIGHT REFLECTING TUBE - The tube is made of aluminum and coated with an efficient, silver-containing, and light-reflecting (98%) layer (compared to a new mirror with a light reflectance coefficient of 90-95%). The minimal losses in the light transmission process allow for the use of even 12m long SR_ light tunnels. During installation, it is not necessary to reduce the length of the lighting tube, as it is designed according to the telescope principle, simply push one tube into another to achieve the desired total length.

ROOF ELEMENT - It consists of an aluminum frame with a 4mm thick tempered glass. The light-reflecting tube is attached to the inner profile of the frame. The side parts of the roof element are made of aluminum sheet or special organic glass (for the L model with additional attic lighting) and connected with a connection. The roof element is painted in gray-brown RAL 7022 tone, which perfectly matches all standard roof cover colors.

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.

ELBOW - With the help of the SRK elbow, it is possible to change the installation angle of the tube from 0° to 65°. The SR_ and SR_-L 550 light tunnels are available with the SRK elbow according to the customer's choice.

The light tunnel is designed for installation on roofs with a slope from 15 to 60°.
