Types of Green Roofs

There are many different types, sizes, and designs of living walls and green roofs. Depending on the desired results and environmental factors, different green roofs and living walls can be built. 

Extensive Green Roofs

The most typical kind of green roofs are those that are enormous. These roofs often require little upkeep and are lightweight. They may be made to fit any size and shape and are frequently used in large-scale structures like commercial buildings and expansive residential rooftops. Large-scale green roof plants are often shallow-rooted and require little to no upkeep and irrigation. These plants often grow slowly and don’t require much watering or care to survive.

Intensive Green Roofs

The most expensive and upkeep-intensive green roofs are intensive green roofs. These roofs are frequently applied to small rooftops in cities. Compared to extensive green roofs, intensive green roof plants are often larger and require additional maintenance. These plants may need frequent irrigation as well as care, such as fertilising and shearing. These plants often grow slowly and don’t require much water or care to flourish.

Hybrid Green Roofs

Intensive and extensive green roof components are combined in hybrid green roofs. For individuals who prefer both low maintenance and heavy upkeep, these roofs are perfect. The plants used on hybrid green roofs are often low-growing, shallow-rooted plants that can survive with little irrigation or care. To preserve their health and growth, these plants might also need routine upkeep and fertilising.

A growing number of people are utilising green roofing and living walls because of their aesthetic and environmental advantages. For those considering installing one, it is imperative to comprehend the various kinds of green roofs and living walls because each form has its own advantages and disadvantages. For successful installation and long-term maintenance, it is crucial to understand the different kinds of green roofs and living walls that are available, as well as the advantages and difficulties that come with each type.

Types of Living Walls

Vertical gardens and living walls are both types of vertical green roofs that are constructed on walls. They can be hydroponically grown, soil-based, or a hybrid of the two.

Living Walls Based on the Soil

Built with soil and organic materials, earth-based living walls are intended to be self-sustaining. The soil serves as the growing substrate and provides plants with the nutrients they need to flourish. Because they rely on soil, soil-based living walls take more preservation, but they also have benefits. Living walls made of soil use less water since the earth retains the water, which eliminates the need for frequent watering. In addition, the soil offers beneficial insects an environment where they can naturally flourish.

Hydroponic Living Walls

Hydroponic living walls are constructed using a combination of water and nutrients as opposed to soil-based living walls. A pump system delivers the nutrients to the plants, using little water in the process. The plants are cultivated in a portable, inert media, like coconut fibre or foam, to make installation simple. Furthermore, because the nutrients are delivered through a pump system, which eliminates the need for frequent watering, hydroponic living walls require less maintenance than soil-based living walls.

Hybrid Living Walls

Combining soil-based and hydroponic living walls creates hybrid living walls. In hybrid living walls, the plants are fed with a combination of soil and inert material. While the hydroponic component delivers nutrients via a pump mechanism, the soil-based component holds onto water. For individuals who want the advantages of both soil-based and hydroponic living walls, hybrid living walls are an ideal option.

An excellent addition to any house or establishment is a living wall. Living walls can be a terrific alternative for property owners who are looking for environmental advantages or who want to improve the gazes of their building. The choice of living wall depends on a number of variables, including the available area, the budget, and the desired appearance. Whatever kind of living wall is selected, it will add beauty and life to any building or establishment.

Difficulties of Installing Green Roofs and Living Walls

Before starting a project, carefully evaluate the costs and labour involved in installing green roofs and living walls. Before starting a project, it is important to take into account the problems that arise from the installation of the green roof and living wall. Here, we’ll talk about the price of installing and maintaining living walls and roofs as well as their resilience and life span.

One of the main concerns with green roofs and living walls is the installation expense. The scale of the project, the type of material utilised, the complexity of the design, and the location of the project all have an impact on how much it will cost to install a green roof and a living wall. For instance, intensive green roofs are more expensive than extensive green roofs since they need more resources, drainage, and labour. Similarly to this, soil-based living walls are more expensive and demand more resources than hydroponic ones. Additionally, building a green roof or living wall in a confined urban space can significantly raise the cost of installation.

When calculating the price, it’s also important to account for the upkeep of living walls and green roofs. The routine maintenance of green roofs and living walls includes weeding, pruning, and fertilising, as well as the occasional repair of weather damage or other problems. When planning a green roof or living wall project, you must take into account ongoing maintenance because it can be costly and time-consuming.

Another crucial element is the robustness and lifespan of living walls and green roofs. The longevity of green roofs and living walls varies widely depending on the materials used and the climate in which they are put, while these systems are typically built to survive for a very long time. For instance, green roofs may not endure as long as those installed in warmer climes if they are installed in harsh climates with excessive temperatures, humidity, and precipitation. In addition, for the intended lifespan, green roofs and living walls must be properly designed and built.

Installing green roofs and living walls involves a number of difficulties, such as expenditures for setup and maintenance and concerns about the system’s robustness and endurance. Green roofs and living walls, on the other hand, maybe excellent additions to any property with careful planning, offering a variety of advantages that last for many years.
