On what kind of rear walls can you mount a living wall?

Did you know that it is possible to mount a SemperGreenwall on virtually any wall? Whether it’s stone, wood, sandwich panels or other insulation materials, our living walls fit seamlessly onto it. We already have a lot of experience with different ways of to mount a living wall, the only condition being that the wall must be able to support 10lbs/sf In existing buildings. The wall is usually already fitted with bricks, wood or other board material. Besides this material, in new construction projects you can also opt for mounting the green wall directly on the insulation layer. This saves wall finishing and unnecessary material. It is also possible to mount the SemperGreenwall on sandwich panels. This article explains which materials the SemperGreenwall can be mounted on and how this works.

On what kind of rear walls can you mount a living wall?

Standard mounting on wood or stone

Generally, a SemperGreenwall is a living wall which is installed on wooden or stone walls. These are the more ‘standard’ rear walls, so the standard installation is also used in this situation. Here, we start by fixing the edge finishing to the back wall: the gutter, side, corner and top profiles. Secondly, the Omega and Z-profiles are fixed vertically to the back wall. The next step is to attach the Flexipanels, which are already completely pre-fabricated, to them. These profiles are fastened 24,5 inches apart, the width of the Flexipanel.

Green facase assembly on insulation

Because the Flexipanels have a TPO (Thermoplastic Polyolefin) backing and the back of the panels overlap, they are fully watertight and root-resistant. This means that the wall does not need to be waterproofed first and roots do not affect the living wall. This is ideal for special construction on insulation, as it allows the SemperGreenwall to be used as a complete outer shell. This means that no additional cladding needs to be placed between the insulation material and the SemperGreenwall.

Constructing a SemperGreenwall Directly on soft insulation

A SemperGreenwall can be applied to both hard and soft insulation. Installation on soft insulation is done with spacers, which are fixed to the wall on one side, while the Flexipanels are installed on the other side.

Insulating effect is retained

Of course, the aim is to maintain the insulating effect of the insulation material. This is why the metal profiles are interrupted by a plastic centre piece. Plastic does not conduct cold or heat. Cold air from outside is therefore not conducted inside and heat cannot escape to the outside. This prevents a thermal bridge and keeps the energy in the building.

Living wall directly mountend on rigid insulation boards

The SemperGreenwall can also be mounted on hard insulation boards. In this case, it’s mounted on the back wall with long screws through the insulation. No spacers are required for this assembly.

Save on labour and material costs

In new construction projects and renovations where the wall finish cannot be reused, it’s cost-saving to mount the SemperGreenwall directly on top of the insulation. In this case, it saves on material costs, as there is no need to apply an additional layer, such as bricks. And this in turn saves manpower and labour costs.

Technical drawings

Curious to know what a mounting on insulation material looks like? Download the technical drawings for a SemperGreenwall attached to rear wall insulation below. These are general drawings and because we want to make sure everything is 100% correct, we always draw the project to size when a SemperGreenwall is purchased.

Creativity and tailor-made solution

Besides using different background materials, there are other ways to get creative when designing a SemperGreenwall. This is because the SemperGreenwall can be attached not only to flat walls but also to curved surfaces. This is due to the flexibility of the material the Flexipanels are made of. See for example the projects below.

Mounting a living wall around screens or other cut-outs is also possible. With the right edge finishing, a beautiful frame is created. Like, for example, this project in Hackensack or this creative solution at the Widener University.

A great thing about applying biophilic elements is that they can be tailored to each individual’s needs. After all, don’t we all prefer to live and work in a natural environment? Don’t forget to think about the connection between people and nature when (re)designing (new) projects.
