The new residential areas, as well as the new transport facilities, make clear the need of recovering green space to improve our environment’s health and our quality life. The green covers can reduce locally the impact of the constructions, as well as offering plenty of economical and ecological benefits such as use and administration of rain water, energy saving: thermal isolation and protection against direct insulation, decrease of the “urban heat island” effect, creation of a more harmonious and pleasant working and living environment, increase of the useful life of the covers’ membranes. To enjoy all the advantages of a green cover it’s necessary to choose the right species to grow on it and, of course, the right substrate to allow a proper growth. BURÉS has a wide offer of substrates specially designed for green covers, adapted to the needs of different projects.
