Façade System with multi-layer bio-composites

Wood-based curtain wall façade system

TRL7 - System prototype demonstration in operational environment

R1 – Rethink, R2 – Reduce

The façade system is a non-structural building envelope made of biobased composites. Through safe off-site production and easy on-site assembly, they provide flexible solutions customized as opaque or transparent wall elements.

Technical Features

The façade combines good thermal properties with long-term carbon sequestration within the building material. Its structure comprises: 1) a three-layer system, 2) a fire shield on the building side, 3) fire-resistant biocomposite profile as efficient one-size-fits-all substructure, 4) customisable exterior building finish with various materials.

Next steps, R&D needs

Increasing cost efficiency

Increasing biobased parts

Reducing weight

Production process optimization"

Other information

A biocomposite material is used for the façade profiles replacing energy intensive and heat conducting aluminum. The fixing substructure offers aesthetic customization options for the exterior building finish allowing for wooden lamellas, porcelain tiles, fiber cement or other types of panels for external cladding. This allows both high customer satisfaction and a cost-efficient production process of a one-type-fits-all substructure. After successful fire resistance tests, the façade is applied to the BASAJAUN demo building in southern France.
