Extensive green roof
Green roofs give a special character to today's architecture, embellish entire urban neighborhoods, restore the green areas lost through the construction of the soil to nature, and help to better integrate the buildings into the natural context.
An extensive green or green roof is not only beautiful to look at, but also offers numerous other advantages: rainwater regulation, reduction of temperatures, sound insulation, air purification and a stimulus to biodiversity.
It represents a technical system for green roofs characterized by reduced thickness, low weight and low maintenance.
Its aesthetic function is pursued through a careful selection of the self-regenerating vegetation of the roof. The green mantle is mainly composed of a mixture of perennial herbaceous varieties suitable for the extreme conditions of the roofs or with plants specially selected to attract bees and butterflies.
To lower the need for maintenance, plant species are used that have, at the same time, a limited development and low cultural needs such as those belonging to the genus Sedum (succulent and rustic plants).
To start an extensive self-sufficient green roof, which therefore does not require maintenance, it takes about one or two years from the planting of the plants.
The extensive green roof does not require irrigation and maintenance is limited to a couple of interventions a year for fertilization, weeding or mowing in the case of very active plant species.
The green roof is a victory for the modern designer who is constantly looking for the interaction between the building and the environment.
