“We are revolutionising the construction sector by providing a building system that is climate neutral, healthy, and effective, designed to be safely returned to nature after use,” says EcoCocon CEO Bjorn Kierulf. The panels manufactured by the Swiss company are cradle-to-cradle certified and made of FSC-certified wood and straw.

The panels comprise an external layer of wood fibre, which prevents heat loss and ensures the correct humidity transfer, a straw-based central insulation layer, created using multidirectional press technology, and a load-bearing twin stud frame made of wood from sustainable forestry. The surfaces are ideal for clay plaster and compatible with a variety of standard interior finishes. The EcoCocon system, made of 98% renewable materials, is permeable to vapour, airtight, and with no thermal bridges.

Prefabricated in a factory under rigorously controlled conditions, EcoCocon panels can be assembled quickly and – although built to standard length and thickness – are suitable for any building project.

Founded in 2008, EcoCocon has built 43,000 square metres of walls thus far, capturing over 3,000 tonnes of CO₂. It is present in projects throughout all of Europe, from Finland to Austria and the United Kingdom.
EcoCocon is certified by the German Passivhaus Institute – an independent body that has developed the only internationally recognised standard relating to the concept of passive houses – and received an Innovation Award in 2019 from the same Institute.
