Installation of the Solar Light Tube in a residential space.
They are ecological systems, where natural light is captured and directed through internally coated tube by highly reflective material, which minimizes the dispersion of the rays and allows a supply of light at considerable distances, without heat or cold transfer.


SUN PIPE – SUN TUNNEL -SOLAR LIGHT TUBE - Capture, Transmission and diffusion of natural lighting. Chatron's SUN PIPE – SUN TUNNEL -SOLAR LIGHT TUBE are systems for capturing and transmitting natural Daylight to the interior of the buildings where they end with the solar diffusers.

The dome is placed on the outside and maximizes the capture of natural light that will enter the SUN PIPE – SUN TUNNEL -SOLAR LIGHT TUBE and route it to the solar diffuser placed inside the installation. In the background it’s as a Light Tunnel. The great advantage is that it can bring natural light to spaces that were otherwise was practically impossible to illuminate: lighting for indoor bathrooms, corridors, cellars etc. The domes, SUN PIPE – SUN TUNNEL -SOLAR LIGHT TUBE and solar diffusers have unique and selective features, so they transmit the “good” light and eliminate harmful light (UV, and part of the Infrared) so that the heat or cold transmission to the interior is residual.

Manufactured in Portugal, in Europe, Chatron's SUN PIPE – SUN TUNNEL -SOLAR LIGHT TUBE feature a design based on energy efficiency and have great integration with the global lighting of buildings (PERSA SUN PIPE – SUN TUNNEL -SOLAR LIGHT TUBE and URANUS SUN PIPE – SUN TUNNEL -SOLAR LIGHT TUBE versions).

Studies have shown that on average about 80% of working hours in closed environments can be done under natural lighting, thus contributing directly to the reduction of energy consumption and consequently to the improvement of the energy efficiency of buildings. The physical and psychological health of all workers depends on the working conditions and if it takes place in natural spaces, provided with natural light (illuminated with SUN PIPE – SUN TUNNEL -SOLAR LIGHT TUBE, with Persian light tunnels, Uranus integrated lighting), then it will be better than elsewhere without these conditions.
