The term “green walls” encompasses all forms of vegetated wall surfaces. However, there are three major system categories that fall under this term’s rubric: green façades, living walls, and retaining living walls. Living walls or green walls are self-sufficient vertical gardens that are attached to the exterior or interior of a building. They differ from green façades (e.g. ivy walls) in that the plants root in a structural support which is fastened to the wall itself. The plants receive water and nutrients from within the vertical support instead of from the ground.
Unlike other systems made of bags, plastic, and felt the Green Living Wall is made to last. Since they are each manufactured from aluminum or stainless and preferred by LEED, there is no threat of expansion and contraction or the degradation of materials which become a health, safety and maintenance concern.
Green Living walls are available as wall-mounted systems or a free-standing system. We have pioneered growing food vertically and organically without hydroponics, called Urban Farms.
