The advantages of the green wall
Aesthetics
Soundproofing
The substrate used in the baskets coupled with a 6 cm air knife absorbs sound, prevents echo-resonance and reduces the impact of airborne noise.
Sound absorption: A4 / Dla = 14db
Sound reduction: B3 / Rw = 61DB
Earthquake resistance: class 5 zone – Fire resistance: standard B, s1-d0
Thermal insulation
Fight against heat islands
Plants help to cool the air in urban areas by combining the effects of their shade and their evapotranspiration. The shade made by the vegetation reduces the surface temperature of structural elements and buildings by reducing the share of solar energy they perceive.
Evapotranspiration cools the air through the water present in plants. There is a decrease in temperature of 2 to 3 degrees in the canyon streets thanks to the green walls
Alexandrii E. and Jones P. (2008). Temperature decreases in an urbancanyon due to green walls and green roofs indiverse climates, Building and Environment.
Thermal insulation of the building
The greening of the facades has an impact on the temperature of the outside air and acts as a thermal insulator, which regulates the temperature
inside buildings.
It reduces the reduction in energy costs linked to air conditioning in summer or heating in winter. The cooling of the wall varies from 7 ° to 15 ° in summer and in winter, cuts off the wind effect on the facade thanks to the combination of the air gap separating the wall from the plants and the substrate.
According to a study by the Montreal Urban Ecology Center in 2011, the city’s green walls generate energy savings in buildings of 47% when it comes to irrigated walls.
Reintroduction of biodiversity
The green wall is a real asset for biodiversity thanks to the diversity of the plants chosen. insects and pollinators come to forage on the plant wall.
It is a food resource for wildlife. The birds come to nest and find a food resource in the wall. An ecosystem is recreated.
Green wall: The green wall is both a food resource and a place of life for fauna and in particular for the birds that come to nest. Honey plants encourage the arrival of bees and insects.
Choice of over 300 plants.
Wall climbing plants: climbing plants do not allow birds to come and nest in the first years of shoots. Insects and bees will come if the chosen plants bloom.
Choice of 40 plants, more limited choices.
Ambient air pollution control
Air pollution control
The plants in the plant noise barrier trap dust and CO2 and emit oxygen. The green wall uses the process of bio-filtration which captures pollutants such as nitrogen oxides, hydrogen sulfide and organic compounds.
Choice of depolluting plants
There are different types of plants that are more depolluting than the others: those with thick and small leaves as well as all mosses.
Fire resistant
We guarantee that the VERTIFLORE® system is classified with a fire resistance in EUROCLASSE B-s1-dO.
Resists seismic waves
Resists seismic waves: can be installed in a class 5 area.
