Modular Green Walls

A modular green wall system offers architects and developers design flexibility to create both indoor and outdoor vertical green walls. The high strength modules, containing growing media and plants are lightweight, may be easily replaced to cater for design changes and allow for a range of growing media depth to cater for a wide plant selection.

Benefits

Green roofs and modular green walls are aesthetically, recreationally and environmentally rewarding as well as "value adding" to a wide range of commercial, residential and institutional buildings.

Benefits include reduced energy costs, improved sound insulation, reduced storm water run-off, a habitat for fauna and flora, reduced pollution and enable unattractive and heat absorbing roofs and walls to become environmentally sustainable structures.
