Do you still have questions about green roofs?
What's the difference between Prairi'folia, Arbusti'folia and Nati'folia?
All Le Prieuré solutions are semi-intensive roofing solutions, containing between 12 and 30 cm of substrate, but can also be adapted to greater thicknesses.
It’s mainly the plant cover that changes from one solution to the next, with country, shrub or wilder renderings.
What are the advantages of a semi-intensive roof?
Unlike extensive roofing, semi-intensive roofing is generally heavier, with CME weights of 130 kg/m² and above. It also offers better water retention and greater possibilities in terms of landscape and biodiversity. It’s the ideal solution for greening roof surfaces on concrete slabs, with a weight load that’s easy to accept.
What's Nati'folia's added value?
The nati’folia solution is a semi-intensive roof, enhanced with biosdiversity features. Substrate types can be differentiated, with zones of sand or pebbles, as well as thicknesses.
It’s also possible to add refuges for biodiversity, such as piles of dead wood, scree, nesting boxes, and even rooftop ponds to create occasional watering holes.
Should beehives be placed on roofs?
The installation of beehives and the possibility of producing their own honey on city rooftops has aroused great enthusiasm among project promoters, as the protection of bees seems essential for biodiversity. On the other hand, this solution, which may seem interesting, has its share of harmful consequences, and the practice is banned in several urban centers. Honey-producing bees(apis mellifera) represent just one of a thousand bee species. The proliferation of this species therefore poses a threat to other, often solitary, bee species, as well as to other pollinators.
