Shading devices

Which shading devices for my eco-friendly home ?

Shading devices, whether adjustable or fixed, allow to modulate natural light entering into the house, to prevent dazzling by the sun and to control excessive solar radiation. Below are some solutions and their main characteristics.

Horizontal and vertical caps

  • Fixed elements integrated into the construction of buildings
  • Act as solar masks
  • Examples: balconies, verandas, roof overhangs, pergolas…
  • Materials: concrete, prefabricated metal, aluminium or wood (in the form of lamellae)

Horizontal caps

Ideal for south facing locations. It acts as a sunscreen, i.e. when the sun is high in the sky in summer the rays are blocked. In the same way, the rays penetrate when the sun is low in the horizon in the winter.

Vertical cap

Ideal for eastern and western orientations because it stops the sun’s rays low in the horizon. It can be adjusted to take maximum advantage of solar gains in winter.


Venetian blinds

System of slats of different sizes (about 5-10 cm) connected together by wires of different materials, which allow the adjustment of their inclination and closure. The lamellae can be of different colors and geometries. They can be concave, convex or flat, thus modifying the thermal and light behavior in the interior space.

It is also possible to place vertical blinds, the adjustment being done in the same way, but in a horizontal direction.

The great advantage of this system is the possibility of adapting to the needs of the tenants in real time, thanks to the different possible inclinations (with 90 degrees of rotation possible), which allows sun protection while illuminating the interior space with diffuse natural light.

There are also horizontal outdoor blinds suitable and interesting for bioclimatic houses.

To go further, it is possible to integrate thermometers or anemometers connected by home automation to the blinds in order to control their automatic opening and closing.

The materials of these devices must be resistant over time to atmospheric and climatic aggressions, must be strong enough to withstand strong winds while remaining light enough to facilitate the handling and handling of the blades.
