Green walls, also known as living walls or vertical gardens, are structures that incorporate plants into their design. These walls can be installed indoors or outdoors and are often made of modular panels that hold soil and plants. They help improve air quality, reduce noise, and provide insulation for buildings. In addition to their environmental benefits, green walls enhance the aesthetic appeal of spaces. They can be customized with various plant species, creating vibrant displays that promote biodiversity. Many urban areas are adopting green walls to combat the effects of urban heat islands and improve overall city livability.
