Outdoor green wall: 10 years minimum guarantee

With 95% of the plant species that can support the exterior, the outdoor green wall brings a biodiversity that is unique in France.

A real solution in towns, with their cruel lack of green spaces.

They make it possible to combat heat islands and air pollution thanks to the absorption of fine particles (diesel).

Among their strengths, they also offer a very good sound and thermal insulation.

An outdoor green wall: Second generation

Mur végétal extérieur génération 2


We are specialising in green wall since 2004. In addition, we have been able to study a large number of substrates. Be it organic or mineral, and a multitude of technologies.

Many technologies of the first-generation proven to be unsuitable for the creation of green wall.

From this observation, Jardins de Babylone knew how to exploit the substrate better suited to the condition of the verticality. This is in order to face the difficulties of the first-generation green walls and to lift a technological brake.

The outdoor green wall to fight against heat islands in the city

Sous titre

Cities often have 1 or 2 degrees more than the outskirts. This difference is due to their urban density and the concentration of human activity.

The creation of outdoor green wall makes it possible to lower the temperature. Usually through the substrate and by the evapotranspiration of the plant.

With the loss of water and by the exchange of heat between water and air, the temperature lower. Generally speaking, it is a phenomenon called plant evapotranspiration.

For a significant effect, it is of course essential to have large plant surfaces.

Decontamination of fine particles in cities

Sous titre

The plant is an effective means of absorbing fine polluting particles. In fact, this pollution particle is responsible for 42000 deaths in France per year.

Several studies show that vegetation filters fine particles (including PM10) (Beckett, 2000). It also absorbs pollution, including nitrogen dioxide and sulphur (Yin, 2011).

The resistance of the substrate to the settlement

Sous titre

The fibre substrate preserves all its integrity and guarantees:

  • A longevity over time thanks to its recycled plastic fibre structure which is resistant to settlement.
  • An excellent alternative to substrates of organic origin (sphagnum moss, peat), which decomposes and invariably collapses.

A frost resistant substrate

Sous titre

The thickness for an outdoor green wall is 20 cm. The substrate we use in our green wall helps protect the roots from the cold. It also ensures a real longevity for the plants.

Plant replacement remains exceptional and thus reduces maintenance costs.emains exceptional and therefore reduces maintenance costs.

Regulated watering frequency

Sous titre

The frequency of watering is also greatly reduced. For example, a green wall exposed to the south in the Paris region will have the following frequency:

  • Winter: to be watered every fortnight.
  • Autumn: once every three days.
  • Spring: once a day
  • Summer: twice a day

Its capillarity makes it possible to reach the point of settling. That is to say, that unlike another technology, the residual water evacuated by the green wall is almost zero.

biodiversité en ville

A contribution of biodiversity in the city

Sous titre

With 25 plants per m², the outdoor green wall has the advantage of being a true vertical ecosystem, a corridor of biodiversity in the city.

We can work with endemic plants in the project area. The crop support allows for the use of 95% of the plant species.

Sound and thermal insulation of the building

Sous titre

The outdoor green wall makes it possible to isolate the building from the solar radiation during hot seasons. On the other hand, it keeps the heat during cold season and acts like a second coating.

In built-up areas, solar energy heats buildings as well as any mineral surface. In agricultural or vegetated areas, it’s absorbed by the plants.

The building thus stores energy which heats the air in the non-permeable areas. They then cool down less rapidly at night.

This insulation is also thermal because it reduces the noise of the city.

Give back the smile to the inhabitants through plants

Sous titre

The plant acts on our social well-being.

Green spaces create social cohesion, moments of interdependencies between citizens that come from different social classes and ethnic groups.

The green wall is well known and appreciated by Parisians who are 52% for the realisation of plant walls during the project tender launched by the mayor of Paris in September 2014.
