EcoCocon - An innovative panel system revolutionising construction brought to you by Ecological Building Systems and EcoCocon

The EcoCocon innovative straw wall system is revolutionising construction by making the best of natural materials while ensuring healthy, comfortable, and energy-efficient living at the same time.

EcoCocon panels are made of 98% natural renewable materials. Making them as close to nature as possible results in high indoor air quality with no harmful substances emitted. The entire system is permeable to vapour – it allows excess humidity to escape – and with no thermal bridges and good airtightness, it leaves no space for draughts or mould. Natural materials create a healthy indoor microclimate with even temperatures – warm in winter and cool in summer.

Thanks to its unique cellular structure, straw has been used in construction for thousands of years. Combined with modern technology, we have succeeded in further improving its performance and achieved exceptional insulation properties. With no thermal bridges and easily achieved airtightness, reaching the Passivhaus standard has never been easier.

With more than 10 years of experience, our system fulfils the highest quality requirements, including the Cradle to Cradle and the German Passivhaus Institute certificate. EcoCocon ranked 4th in the first-ever global Product Innovation Challenge by the Cradle to Cradle Product Innovation Institute and received an Innovation Award 2019 for “Regionally available and renewable materials”.

Start Building Naturally

EcoCocon was founded with the idea to find a way to create real and affordable cradle to cradle buildings. Buildings that are made of

renewable materials, and would last decades before being returned safely to nature after use. Buildings that would contain healthy, locally sourced materials and leave a minimal ecological footprint.

Today, our mission goes beyond the borders of our company. We are a global network of passionate individuals who want to be the voice of change in the construction sector. Up till now, we have manufactured more than 63,800 m² of EcoCocon walls, sequestering about 7 199 000 metric kilograms of CO2.

EcoCocon simplifies sustainable construction. Our prefabricated straw panels combine performance, speed, and carbon savings in one smart solution. From airtightness and insulation to certified circularity, every part of the system is designed to meet tomorrow’s building standards — today. Whether you’re designing homes, offices, or public buildings, EcoCocon empowers you to deliver healthy, low-impact projects with minimal complexity and maximum flexibility.

Key Benefits

Excellent thermal insulation

Our system is a Passive House certified component and provides outstanding thermal insulation properties with no thermal bridges.

Smart airtight and diffusion open concept

Airtightness is easily achieved by installing a breather membrane between the panel and the protective fibre board.

Quick and precise assembly

Precision-cut prefabricated panels allow for simple and rapid installation on site.

Made to measure for any design

Panels are custom-made to fit any building design – residential, commercial, and public.

Natural and circular

Composed of 98% natural, renewable materials with no additives, EcoCocon panels use wood and straw, a byproduct of wheat production.

Carbon sequestration

Wood and straw in EcoCocon panels naturally capture and store atmospheric carbon dioxide through photosynthesis during the growth phase.

EcoCocon panels achieve REI 45 fire resistance even when uncovered. Adding layers further enhances their fire performance.
