Embellishing terrace roofs using horticultural methods all the while enhancing the insulation capacities of the complex is the objective of Sopranature®. 


The product is available in several versions to tailor the planting system to the needs, and contributes effectively to sustainable construction – it helps to save energy (thermal insulation), regulates temperature in the summer, improves landscape quality, promotes biodiversity, uses renewable products and plant species that need little water and fertiliser, limits the storm water run-off water into rainwater draining systems.

Sopranature® systems are the perfect way to create sustainable green roofing solutions, promoting biodiversity, and turning what would otherwise be wasted space into useful areas for both people and vehicles.

Sopranature® green roofs offer a host of advantages, both in terms of technical performance and promoting sustainability.


Building owners may decide to install a green roof for many reasons, including protecting the environment, increasing the value of the building, creating additional green space, marketing power.

  • Extending the useful service life of the roof:
    The green roof protects the building’s roofing membrane and extends its useful service life. Reduction of daily temperature fluctuations reduces heat expansion and contraction, which are the main causes of premature roof aging. The green roof assembly also protects the membrane from UV rays.


  • Reducing heat islands:
    Much research both in Canada and around the world has demonstrated the effectiveness of green roofs for reducing the urban heat island effect. Solar energy is absorbed by the green cover and the water in the growing medium evaporates into the atmosphere, refreshing the surrounding air.
  • Stormwater management:
    Green roofs help to better manage stormwater runoff by retaining precipitations in the growing medium, plants and capillary mat. With a high capacity for water retention, the green roof reduces the volume and runoff flow into stormwater sewer systems.
  • Air filtration:
    In addition to transforming CO2 into oxygen, the plant cover filters atmospheric pollutants in the form of particles deposited on foliage and growing medium. 10 m2 surface covered with grasses can eliminate 2 kg of suspended particles from the air each year.

Natural habitats for fauna and flora - the greening of roofs promotes biodiversity 
and encourages a variety of wildlife and plants to thrive.
