Green walls, also known as living walls or vertical gardens, are structures that incorporate plants into their design. These walls can be found in both indoor and outdoor settings, providing aesthetic appeal and improving air quality. They are often made using modular panels or systems that support various types of vegetation, allowing for diverse plant selections. In addition to their visual benefits, green walls help regulate temperature and reduce noise pollution. They can also promote biodiversity by providing habitats for insects and birds. Overall, green walls contribute to sustainable architecture and enhance urban environments, making them increasingly popular in cities worldwide.
