A Spanish SME specialized in the sustainability field has designed a series of vertical garden systems. The company is looking for a sustainable and waterproof board alternative to the standard PVC panels they are nowadays applying in their systems. The company is searching for an international construction materials manufacturer or distributor able to provide an alternative board under a supplier agreement.



The company was established in 2014 and has grown constantly since then. It is deeply specialized in nature based solutions, through the integration of nature and architecture. The Spanish SME has developed different systems for vertical gardens, green roofs, natural pools and other green tools. Due to that experience it has participated on European funded projects to implement green infrastructures in urban environments.

The company is seeking to reduce the carbon footprint of its construction systems by using more environmentally friendly and plastic-free materials. At the moment the company is using PVC panels as a waterproof layer to implement its vertical garden systems, but they are looking for more sustainable materials to perform the same functions and achieve equivalent performance. The company envisages different alternatives for these panels, among others:

·Plastic-free boards.
·Panels made of biodegradable plastics.
·Boards made of recycled plastic adding the possibility to be revalorized in case of eventual dismounting of the vertical garden.

These panels will be anchored to walls and facades of existing buildings on the structure of the building itself, or on a new metal frame structure to be built for this purpose. The substrate will be placed on the surface of these boards to house the plants in the vertical garden.

The cooperation will be based on supplier agreement. The company has experience in foreign cooperation and they are looking for suppliers of waterproof panels made of sustainable materials.

Technical Specification or Expertise Sought

Cooperation sought: 
Technical parameters of sought products are: - Quality and waterproofing guarantee for ten years. - Must be able to be stapled or screwed. - Must have resistance to be screwed to strips. - The panels must be able to be joined together and sealed. - Must be able to be cut easily. - To reduce the carbon footprint compared to the standard PVC boards they are nowadays applying in their system. - Fire resistant if possible. See attached images and drawings for more info about the vertical garden system developed.
