At Calathology, we know that the world around us is becoming busy, and we understand that as part of this “busy,” there is fast becoming less and less green space.

However, all is not lost; the good news is we don’t have to lose the feel of nature around us entirely.

Businesses and property owners are now looking at new ways to breathe green life into all types of spaces, with this creative and innovative solution coming in the form of living walls.

Living walls provide numerous benefits for both the environment and the local community they serve. In this post, we explore these further and delve into what a living wall actually is.

What is a living wall?

It is well recognised that plants have a positive effect on our well-being, however we know that the spaces in which we occupy are becoming smaller and smaller, posing the question, how can we make our green spaces bigger?

Living walls.

Also known as green walls, vertical living walls are just that: vertical green spaces found on the sides of buildings, walls, and even vertical partitions for use in office spaces.

This means these vertical green walls can be designed for internal and external purposes where you will find an array of suitable plant life appropriate for the environment (working with a professional team like Calathology is your best chance to achieve a successful living wall, as choosing the most appropriate plants for the environment is vital).

In most cases, planning permission is not required, but it is recommended that you speak with your local authority for further guidance if you’re making any alteration to a building.

This will provide you with peace of mind and keep you right in the long run.

Due to the increasing popularity of vertical green walls, there are now numerous living wall systems to choose from, suitable for any location.

Types of living wall systems

Tray–tray wall systems are best suited to indoor environments, using plants that have been pre-grown and then simply placed into the available wall trays. This type of system offers great design flexibility as you can place trays on the wall where you see fit, i.e., where they look aesthetically pleasing, and trays can easily be replaced. However, a word of caution: This living wall system requires a good level of care and attention to avoid bug infestations, fungus, and even mould. We advise you to replay trays at least once per month to help avoid this.

Modular – this is a longer-term green wall live system and can be used in any type of climate. Again, this system includes pre-grown plants but greatly benefits from appropriate drainage and irrigation systems, ensuring a healthy wall. Modular living wall systems also allow you to create all types of structures and designs, and they’re suitable for all shapes and sizes of walls. Plants have the freedom to grow, and you will also find they have a longer lifespan in this type of system than others – making this one of the most popular types of green walls.

Freestanding—These smaller, easy–to–move systems have the flexibility to be placed indoors and outdoors, in the middle of a room, against a wall, set as room dividers, and so much more. These living wall systems are on a smaller scale, add aesthetically pleasing entrance ways to buildings, make people feel happier and more productive at work with greenery around them as creative partitions, etc.

Benefits of living walls

Improved air quality – Plants placed in living walls help to filter carbon dioxide and other pollutants in the air and convert these into healthy oxygen, improving the surrounding air quality and supporting people’s health and well-being as it reduces the feeling of a “stuffy” atmosphere and reduces our carbon footprint.

Reduction in noise pollution – Living walls can act as great sound barriers, absorbing up to 40% of the environment’s sound waves and dampening sound by up to 15 decibels.

Temperature control – vertical walls help to cool the air temperature as the plants absorb sunlight, they reflect approximately only 30% of this back into the environment. These walls also help to reduce heat loss by 30%, helping to regulate building temperatures and save you money on your energy bills.

Improves productivity – people feel happier, relaxed, and more motivated when they are surrounded by nature, and green walls help to provide just that.

Aesthetically pleasing – vertical living walls are a beautiful design feature offering great aesthetic appeal and statement. Adding value to properties and increasing footfall as a result.

Supports biodiversity – By providing habitats and shelter for local wildlife, you’re also supporting an increase in biodiversity, which supports a more sustainable future. All materials used in living walls are also reusable and fully recyclable.
