The Vertical Garden is composed of three parts: a metal frame, a PVC layer and felt. The metal frame is hung on a wall or can be self-standing. It provides an air layer acting as a very efficient thermic and phonic isolation system. A 1cm thick PVC sheet is then riveted on the metal frame. This layer brings rigidity to the whole structure and makes it waterproof. After that comes a felt layer made of polyamide that is stapled on the PVC. This felt is corrosion-resistant and its high capillarity allows a homogeneous water distribution. The roots are now growing on this felt.
Watering is provided from the top with the tap water being supplemented with nutrients. The process of watering and fertilisation is automated. The whole weight of the ‘Vertical Garden’, including plants and metal frame, is lower than 30 kg per square meter. Thus the Vertical Garden can be implemented on any wall without any size or limitation of height.
The Vertical Garden as it is known in English, is something closer to a living painting than to a garden. Actually I named it le mur vegetal, meaning vegetal wall. I’m a scientist, a botanist and the Vertical Garden is derived from many observations I made in natural places mostly in tropical areas for more than 30 years now…
My scientific approach is essential for designing the whole system and for selecting the plant species suitable for each peculiar location.
