Why build with earth?

Contemporary and sustainable

Building with earth is modern and sustainable. Earth is a material that is widely available, reducing the need for materials to be transported over long distances. It is easy to excavate and its processing into building materials requires no chemicals. The durability of earth buildings is unparalleled – many buildings have lasted for centuries. Earth will in future continue to be a popular building material because it is a simple way of making living environments more ecological and is inherently sustainable.

Optimal insulation properties

Comfortably warm in winter and pleasantly cool in summer: earth walls function as natural air conditioners. Modern internal insulation systems using earth contribute to creating interiors that are comfortable to live in. They are vapour permeable and have good capillary conduction properties, which means they can effectively absorb and disperse humidity. Due to their natural mass, earth bricks, clay plasters and clay panels can absorb and retain heat well, radiating it gently back into the room as the air temperature drops. As a result, earth walls contribute to creating comfortable interiors and help to conserve energy.

Healthy room climate

The use of clay plasters in combination with clay paints ensures that walls can effectively absorb humidity in the air. The relative humidity of air in living environments should not fall below 40% nor exceed 70%. Walls that are plastered with clay act as a natural humidity buffer, regulating the air humidity at a level between 45% and 55%. The clay minerals in earth and clay plasters are also able to bind odours and pollutants in the air, reducing the level of bacteria and harmful substances, and accumulate less dust due to their antistatic properties. Earth contributes to healthy and comfortable living environments.

Individual creativity

Earth is a material that is inherently easy to shape. It can be used to create all manner of different and individual surface textures and there are few limits to what one can design using modern earth building products. Available in naturally warm colours and formable into a variety of surface structures and textures, earth can be used to create unique and atmospheric living environments.
Earth hardens by drying. By adding water, it can be made malleable and be reshaped.

Flexible simplicity

Modern prefabricated earth building products make it easy to start using this natural and age-old building material. As such earth represents an attractive alternative to conventional materials, even for beginners. Because earth building products due not cure chemically but harden by drying, they are easy to work with at a gentle pace.
Many earth building products are easy to use oneself by following the instructions in our conluto work sheets. Special tools and machinery are not needed for most applications.

Earth and timber preservation

Earth has a maximum equilibrium moisture level of 6% by weight. As a result, when used alongside timber elements, it helps to keep the wood dry. The equilibrium moisture level of dry wood is rarely less than 9%, while that of construction timbers is often over 12%. The earth therefore draws moisture out of the wood, reducing its susceptibility to fungus, rot or insect infestation.
