– the greening of roofs is not only an environmental trend in society, but also benefits,
– green roofs protect the building from overheating in the heat, which greatly reduces costs for air conditioning. In the winter, green roofs, by contrast, have an isolating effect, reduce the amount of energyrequired to heat buildings
– green roofs retain rainwater, absorb it, thereby reducing the load on storm sewers. Rainwater is a source of water for living plants,
– green roofs provide protection from the city noise
– are aesthetic and serve as a decoration of the cities.
