What is biotroofs?

Biotroofs are living roofs or green roofs that are covered with plants, such as grasses, sedums, and wildflowers, which can thrive in the harsh conditions of a roof space. They consist of several layers, including a waterproof membrane, drainage layer, and growing medium. The plants and soil on the biotroof provide insulation, absorb rainwater, filter pollutants from the air, and provide habitat for insects and birds. Biotroofs can help reduce the urban heat island effect, improve energy efficiency of buildings, and increase biodiversity in cities. They are commonly used in commercial and residential buildings, as well as public spaces such as parks and public buildings.
