LIGHT TUNNEL
with flexible light transmitting tube
SLT Plus - light tunnel consists of : dome, light transmitting - 3m long tube, ceiling frame, prismatic diffuser,
SLO light kit and installation kit.
FLASHING
Flashing is used for a correct light tunnel
installation into the roof slope. Flashing ring
is equipped with drips openings which
can drain away the eventual condensate
outside the light tunnel. In the middle of
the flashing there is a reflective ring, the
first element of which reflects the light
entering into the light tunnel via a dome.
CEILING FRAME with diffuser
White ceiling frame and diffuser are the only
elements visible in the ceiling after the light
tunnel is installed. The sun’s rays reflected
from the walls of light transmitting tube
are directed downwards the light diffuser.
The main diffuser’s role is to spread the light
evenly throughout the room. The light
diffuser consists of the transparent and mat
diffusers equipped with UV filters.
Both (transparent and mat) diffusers are
placed inside the seal, which unites them
into one entity. Between the diffusers, there
is an air chamber, which plays the role
of insulation between the room interior
and light transmitting tube. It minimises
the level of condensation inside the light
transmitting tube.
FLEXIBLE LIGHT TRANSMITTING
TUBE
Light transmitting tube is made of
metallised polyester, additionally
strengthened by wire. Such a design
enables tube to attain durable light
transmitting tube. Thanks to its flexibility
it is an ideal solution to install over short
distances in rooms where there are
construction obstacles, which have to
be avoided. The advised, flexible tube
length is 4m maximum-for 350 mm tube
in diameter and 6 m for the 550 diameter
tube. In case the tube is longer than 5m,
the use of SLC hangers is advised.

DOME
The dome is made of polymethacrylate,
a material resistant to mechanical
damage. The dome’s shape and height
is a combination of self-cleaning effect
and co-efficient of overall sun light
transmittance to building interior. The
low electrostatic activity of the dome’s
surface means that the dust adheres to
dome’s surface only lightly, so the rain
quickly washes the dirt away. The dome’s
shape also assists in the quick removal of
snow.
