Living Walls

The Vertical Casacade System


Living walls, or green walls, are self-sufficient vertical gardens that are attached to a free-standing frame or to the exterior or interior of a building. With gardens becoming smaller, making use of every surface makes sense and can look striking. Many types of plants will tolerate the high life in a green wall, from herbs and fruit to grasses and ferns. Whether in sun or shade, covering walls with plants can enhance the smallest of spaces.


A unique and highly innovative living wall system that can be easily built and maintained. System that is robust, affordable, easy to use and offers an extensive selection of plants. 

Vertical Cascade Garden is a system of self-watering and reinforced containers where custom made flowerpots are attached and secured. Approximately 35 plants per m2 ensures a rich and breathtaking appearance where creativity has no limits.

  • Automatic irrigation system
  • Simple maintenance
  • Instant impact, 1L plants planted from day one
  • LEED and BREEAM credits

Case Study:

University of Greenwich Interior Wall


Watch this video about the Nemec Living Wall install at the University of Greenwich Green Roofs and Living Wall Centre. Shelley Mosco of Greenwich University's Landscape Architecture department talks us through how simple a nemec wall can be to install. 

The Stockwell Street building has extensive and intensive green roofs which can be seen from many points within the building. But there was no internal vegetation. The studio and circulation spaces are now greatly enriched by the living wall. It freshens the air and provides a dazzling splash of colour to set off the whites, greys and blacks of the building interiors. It is most welcome.

Private Benefits

Improved Energy Efficiency

Green walls can reduce the temperature fluctuations at a wall's surface from a range of 10-60ºC (50-140ºF) to one of 5-30ºC (41-86ºF), in turn limiting the movement of heat between building walls (Minke 1982). They cause this reduction by:

- Trapping a layer of air within the plant mass.

- Reducing ambient temperature via evapotranspiration and shading.

- Creating a buffer against wind during winter months.

Green walls can help lower the air temperature around intake valves, which means HVAC units will require less energy to cool air before being circulated around a building.

Building Structure Protection

Temperature fluctuations over a building's lifetime can be damaging to organic construction materials in building façades. Green walls provide an additional layer of exterior insulation and thereby limit thermal fluctuations.

Green walls protect exterior finishes and masonry from UV radiation and rain. They can also increase the seal or air tightness of doors, windows, and cladding by decreasing the effect of wind pressure (Peck et al. 1999).

Noise Reduction

The vegetated surface provided by strategic urban greenery such as green walls and roofs will block high frequency sounds, and when constructed with a substrate or growing medium support can also block low-frequency noises.

Urban Agriculture

Green walls offer the opportunity for urban agriculture, such as vertical gardens of small fruits, vegetables, and herbs.

Public Benefits

Aesthetic Improvements

Green walls can reclaim disregarded space by providing aesthetic stimulation where it would not otherwise be found. They can also serve to create privacy and a sense of enclosure while limiting the negative psychological effects associated with property demarcation.

Reduction of the Urban Heat Island Effect

The reintroduction of vegetation into urban environments promotes the occurrence of natural cooling processes, such as photosynthesis and evapotranspiration.

With strategic placement of green walls, plants can create enough turbulence to break vertical airflow, which slows and cools down the air (Peck et al. 1999).

Improved Exterior Air Quality

Green walls mitigate air pollution levels by lowering extreme summer temperatures through photosynthesis, trapping particulate matter, and capturing gases.

The ability of green walls to provide thermal insulation for buildings means less demand on power, and as a result fewer polluting by-products are released into the air.

Increased Biodiversity

Green walls can help mitigate loss of biodiversity due to the effects of urbanization, help sustain a variety of plants, pollinators and invertebrates, and provide habitat and nesting places for various bird species.

Improved Health and Well-Being

Buildings that feature and promote access to vegetation have been documented as having a greater positive human health impact than those without (Honeyman 1987).

Studies have shown that visual access to natural settings leads to increased job satisfaction and productivity (Kaplan 2001) and post-operative recovery rates in medical facilities (Ulrich 1983)
