What Do People Say about EcoCocon?


For us it is important to know that we live in a house which is good for our health, for the environment, and in the longer run, for our bank account. The indoor air quality and the soft acoustics created by the natural materials and breathable structures is very pleasant. And to be able to contribute to a more sustainable world by using these materials is very nice indeed. An added bonus is the low energy costs thanks to high insulation values and the materials ability to store and release heat and moisture.

Our School for Life project was based on no-compromise ecological materials. EcoCocon combined with clay plaster ticked all the boxes for a natural product that stores CO2, providing a real solution to the climate crisis. In addition to being a splendid insulation material, EcoCocon has created a healthy indoor microclimate with great air quality. We were also impressed by the ease and speed of construction using the EcoCocon panels.

Steffen Steffensen, Business Developer


I have now enjoyed over three years living in my EcoCocon house, which is the first one in Sweden. The combination with clay plaster works well for the interior climate, and looks really nice. The panels were transported to our island by helicopter and afterwards it took only a few days to put up the walls. I can recommend building with EcoCocon and clay plaster, especially when creatively combined with other ecological building materials and solutions for maximum flexibility.

Rienk Smittenberg, Homeowner


We love our summer cottage with its fresh indoor air, beautiful earthen walls and airy architecture! The house not only feels good to all the senses and purely aesthetic, it is also good to know exactly what is in the walls. The thick walls and clay in harmonious colours make the sound environment completely unique. Every time we get there the air feels fresh even though it may have been weeks since our last visit. Without the house being heated, the humidity is kept at a low level all year round. We have measured this for two years, so this is not just a feeling, it’s a fact.

Maria Sundell, Homeowner


The use of EcoCocon has completely changed my attitude towards the use of natural materials in my profession. As a simple and certified element structure, EcoCocon brings quality to construction with ecological values.
