EcoCocon® is revolutionising construction by making the most of natural materials while ensuring healthier, more comfortable, and energy-efficient living at the same time.

What Are the System Components?

EcoCocon Panel construction system
1.

EcoCocon Panel

At the heart of our system is the EcoCocon panel–a load-bearing twin-stud timber frame panel insulated with homogenous straw infill. Panel thickness is typically 40 cm, with a 30 cm option available.

Panel Types construction system
2.

Panel Types

Panel types include standard panels, braced panels, lintels, sills, and inclined gable wall elements. Different structural demands can be met by placing the panels closer together or by using plywood reinforced column elements.

Box Elements construction system
3.

Box Elements

Box elements are special structural components made from timber, LVL, or GLT and insulated with wood fibre board. They are used in structurally demanding projects to carry heavy loads, bridge large spans, or connect floors.

Airtight Breather Membrane construction system
4.

Airtight Breather Membrane

An integral part of the system is the use of an airtight, yet vapour-permeable membrane on the exterior side of the panels. The membrane also provides weather protection during construction.

EcoCocon is used for:

Performance Hidden in Cells

Natural & Circular

Natural & Circular

Made from 98% renewable straw and wood, the system uses minimal energy and water in production. It follows zero-waste and Cradle to Cradle® design principles for responsible circularity.

Airtight & Breathable

Airtight & Breathable

A breather membrane between the straw panel and the protective fibre board keeps the system airtight while allowing moisture to escape, preserving healthy walls.

Fast Installation

Fast Installation

Prefabricated wall elements arrive ready to mount with screws. A team of three can build up to 60 m² daily, doubling with crane help.

Carbon Capture

Carbon Capture

Straw and timber naturally absorb CO₂ as they grow. Each panel stores around 115 kg of CO₂ per m², actively reducing the building’s carbon footprint.

Fire Safety

Fire Safety

Panels with an exterior airtight membrane resist fire for 30 minutes. The full wall system extends fire resistance up to 120 minutes.

Thermal Performance

Thermal Performance

Panels provide excellent insulation, reducing summer overheating and retaining warmth in winter for year-round indoor comfort.

Versatile Use

Versatile Use

The system works as load-bearing walls up to three stories or infill for taller buildings. It integrates easily with timber, steel, or concrete frames.

Custom Fit

Custom Fit

Wall elements are made to order in 1 mm increments, fitting almost any architectural design and creating structurally-sound, tailored straw walls.

Prefabrication Precision

Prefabrication Precision

CNC-cut panels allow for tolerances within millimeters, simplifying BIM integration and reducing installation time.

Wall Buildup Examples

Choose from more than 30 predefined wall buildups accessible as 3D BIM models for Revit or create your own.
