Green walls are popular, especially those with living plants. Living green walls are beautiful, bring natural vegetation back into urban areas, and even increase oxygen and reduce heat-sink effects.
The other side of a living green wall is not so exciting. Living green walls are creating big (and expensive) problems for buildings, including structural damage caused by roots; ground settlement problems caused by soil moisture differentials; building damage caused by moving and falling branches; drainage system clogs from falling leaves, seeds and fruit; building fabric deterioration caused by excessive moisture retention; vermin and pest damage caused by animals living in the plants; higher heating bills caused by the blockage of winter sunlight; and damage to the building’s waterproofing among many more.
Plants by themselves may not be very heavy, but once the soil, water and structural supports are all added up, there will be significant weight, which the wall or roof may not be equipped to support. In many cases, green roofs require extensive modifications to be carried out on a building just for installation. Over time, the weight and added moisture can compromise the building’s waterproofing.
Green walls and roofs require a great deal of maintenance - continuously. Given the potential damage that may occur to the building structure, professional maintenance of the green wall is necessary. Plants require a constant water supply, so piping or a rainwater harvesting system needs to be installed, which also means that the drainage has to be properly maintained to keep the building free from leaks, mildew and mould. Green walls must also be kept fertilised, composted and mulched.
Living green walls are expensive to install, and even more expensive to maintain. Their ongoing costs may include higher insurance premiums caused by installing systems that might reduce the performance of the building; fertiliser and soil additives; higher water bills; repair and replacement of piping and rainwater collection systems; additional waterproofing measures for the building; new plants to replace those at the end of their lifecycle; high labour costs; and potential dismantling expenses.
Artificial Green Walls
Green walls can still be enjoyed and admired without the accompanying high costs of installation and ongoing maintenance. With artificial green walls, you can eliminate all the problems associated with living green walls. For instance, you don’t have to install support structures and water pipes, or worry about damage to your structure from roots, excessive moisture and pests. When you tire of the look (eventually), you can simply take it down, with the walls behind looking as good as new.
Artificial green walls from Evergreen Walls come in a variety of beautiful, lifelike styles. Choose your style from evergreens and moss to ferns and lavender, and make your space come alive. You can also mix and match different varieties or place a logo or sign in front. With endless design options, and lightweight and durable artificial plants, you can install them indoors or out.
