The gray cement, the monotony of brick, steel and glass give way to the ground cover to add color and life to the buildings.

They are known as “green roofs” , “roofing plant” or “living roofs” and each name can also be applied to the walls. The so-called “green roofs or walls” are not painted as decorative elements, live in color because they are composed of living plant .

Suppliers of oxygen in the heart of downtown

One square meter of grass , produces all the oxygen that a person needs for one year. The same amount of grass caught 130 grams of dust per year polula the atmosphere. Why not have our own supplier of fresh air in the center of large cities?. The photosynthesis of plants help to purify the air because they absorb much of the carbon dioxide present in the environment, to make oxygen.

The benefits of green roofs

Ceilings and walls vegetables have become a form building industry is increasingly used in which each new project must be adapted to the region where it is realized to its climate and building type that is integrated. Using plants as a hedge of a building gives it a beautiful tapestry of natural. It seems that personalizes and helps protect the purity of the air. Besides interacting with the environment of the city, retain urban air pollution , absorb carbon dioxide and reduce heat to cause the sun’s rays reflected on the asphalt.

Modernization of an old technique

Although many countries especially in large cities, have a roof garden is new, in parts of Europe is an existing custom since the nineteenth century. Even much earlier, in ancient civilizations such as Babylon, were common. At the time this practice was reason to maintain thermal comfort in homes as a roof “live” gives a greater sound insulation than conventional and helps reduce the impact of climate change.

Simple vegetable and intensive roofs

When installing roofing plant can build so-called simple green roofs, or who are known as green roofs are simple vegetable ceilings, as its name states, those that are built on a common plant material, which can be grass, moss, flower field and need little or no irrigation. Intensive plant roofs added to many other simple materials as shrubs, flower plants and even come to fit into the same, small trees. Garden roofs are often passable and have characteristic features of the gardens as banks or water sources. Usually require irrigation and fertilizers.

Requirements of “green roofs”

In the roofs vegetables should be kept in mind some requirements, such as using a drainage layer that will eliminate the water that does not require the substrate and a good waterproof antiraíz, which is a special type of waterproofing that prevents roots can damage the building structure.

Green walls complement the roofing plant

Generally the plant does not need earth wall. Is a hydroponic cultivation in which living plants of light, minerals, and carbon dioxide can be both inside and outside of the housing. There are several systems to build green walls, one of which is from modular panels of different types, it is also common planting in concrete plant is to use the concrete pores, moistened by a system of pipes and sprinklers, to be fixing the plant roots. Another way to make living walls using climbing plants is aided by networks or guides benefits of green walls are similar to those of the roofs: thermal and sound insulation, suppliers of oxygen and dust collectors.
