A Biowall might not be something you are very familiar with, but perhaps you have heard of other names for them, such as green walls or living walls.

What exactly is a Biowall?

Biowalls are basically walls that are covered with living plants. There are 2 different kinds of biowall. A panel system, which is made up of soil that is packed into plastic bags. Then the plants are placed into compartments. They are watered and fed by an irrigation system which is attached. The other kind of biowall is a felt system. With this system, plants fit into felt that is backed by a waterproof layer, this is used as the means of growing the plants. When the plants grow, their roots grow downwards which helps to stabilize them.

They are designed for both the inside as well as the outside of a building. They are beneficial for use in a home, but are also good to use in offices. This is because of their ability to purify air. However, they are not meant to replace a traditional HVAC system, but instead can be used to work alongside one.

They are also used for the outdoors, especially in more urban areas. As we are aware, concrete walls and surfaces reflect heat, this makes urban areas a lot hotter than they should be. In the summer months, this produces not only excessive heat, but also bad air quality. This is an effect referred to as the Urban Heat Island (UHI). When a biowall is placed in areas like these, it serves to reduce the effects of UHI.

What are the benefits of a biowall? What about any disadvantages? We will highlight this in future articles.
