Whether it’s indoors or out, the different greenwall and greenroof applications available today each have their own pros and cons, some are classified as living and others not, while a selection can actually be a fire hazard, says The Greenwall Company founder Mark Paul
When it comes to selecting the best option for greening your home or building, the first thing you need to consider is what look and feel you are trying to achieve. Then you should engage an expert to assess the best planting options, irrigation set up, light access and the environment the wall or roof will be installed. Working with a horticulturist and an experienced designer, will ensure your installation lasts the lifetime of the home and in most cases can be moved with you.
Living Greenwalls and Greenroofs
These installations are soilless and actively growing all year round. They require consistent light, food and water, plus require an adequate surface area of the root zone exposed to air movement. If planted correctly and set up with an automated irrigation system, they should require minimal maintenance and will flourish all year round. In addition, by utilising The Greenwall Company’s patented soilless media made up of 94% of recycled materials, the wall is lighter in weight, even when wet, and therefore safer for applying to any structure. It is also not biodegradable so doesn’t require it to be replaced, saving on costs over the long-term.
Potted Plant Walls
This is more of a DIY greenwall, which is essentially a large number of potted plants that are formed to make a design. These walls require constant maintenance with most experiencing ongoing water issues due to a dripper blocking, which results in that particular pot dying and needing replanting. Also, as soil is biodegradable it needs to be replaced frequently. These walls may by cheaper to install initially, but the costs really add up in maintenance, replanting and re-soiling each pot, not to mention the time.
Contrary to popular belief, these walls are actually not living! The moss is sourced from the arctic circle, coated, glued and sprayed with acrylic colours. As a result, moss walls do not provide any of the environmental, health and wellbeing benefits to having living plants in the home. On the pros, they are generally very cheap to install and are good collectors of dust and fibres.
Made from plastics, these fake walls are a quick fix to provide the appearance of greenery in a space and only require some dusting on a regular basis. As they are made of plastics, unfortunately artificial walls actually do more harm to the environment than good due to the production. On another note, the artificial walls collect fibres and dust, which means artificial walls are a fire hazard in the home. The dust builds up and static electricity is generated from walking across synthetic carpet. This has resulted in a number of cases where the plastic walls become highly flammable.
