Green Walls

A green wall, also referred to as a living wall or vertical wall, is a structure that is covered with vegetation. It can be freestanding or attached to a wall, and plants are often grown in a medium such as an engineered growing media, hydroponics, or an engineered substrate.

Green walls offer numerous benefits, including improved air quality, reduced urban heat island effect, energy savings through insulation, enhanced aesthetics, noise reduction, and increased biodiversity. They also provide a natural environment that can positively impact mental well-being.

Plants in green walls absorb pollutants such as carbon dioxide and volatile organic compounds (VOCs), while releasing oxygen. They can filter dust and other particulate matter from the air, helping to create a cleaner and healthier environment.

Suitable plants for vertical green walls include a variety of ferns, climbing and trailing plants, succulents, and flowering plants. The choice depends on factors like light exposure, climate, and maintenance requirements. It is essential to select plants that thrive in the specific conditions of the wall's location.

Maintenance of vertical green walls includes regular watering, fertilising, pruning, and pest control. Many systems incorporate automated irrigation and nutrient delivery to reduce manual upkeep. It is important to monitor plant health and replace any that are not thriving. Some walls require machinery such as elevated work platforms (EWP'S) to reach walls that are high on buildings or hard to reach

Yes, vertical green walls can be installed indoors. Indoor green walls can improve air quality, reduce stress, and enhance the aesthetics of a space. When installing indoors, it is important to consider lighting, humidity, and temperature to ensure plant health.

The cost of vertical green walls varies widely depending on factors such as size, plant selection, design complexity, and installation method. Costs can range from a few hundred to several thousand dollars. Ongoing maintenance costs should also be considered along with a comprehensive maintenance plan carried out by professionally trained horticulturists.

Yes, vertical green walls typically require specialised irrigation systems to ensure even water distribution. These systems can be automated to provide consistent moisture and nutrients to the plants. Proper irrigation is crucial for the health and longevity of the green wall.

The structural requirements depend on the size and weight of the green wall. It is essential to ensure that the supporting structure can bear the load of the plants, soil, and water. Consulting with a structural engineer is recommended for large or complex installations and the the team at Evergreen infrastructure will always assist with this process.

Vertical green walls can improve energy efficiency by acting as natural insulation. They help regulate indoor temperatures by providing shade in the summer and reducing heat loss in the winter. This can lead to reduced energy consumption for heating and cooling.
