History
A mixture of clay and straw was used as an infill material for timber framed building from at least the 12th century in Germany and elsewhere in Europe.[1] Renewed interest in traditional building methods developed from the 1980s after which various natural building architects and builders started promoting the use of light clay.[2]
Usage
Local clay, often local subsoil, is mixed into a slurry with water and then combined with straw or wood chip or other similar material. Wood chips can vary in size from sawdust to 5 cm in diameter.[2] The ratio of clay to other ingredients can be adapted to either increase thermal mass or insulation properties.[3] The mixture is provided with additional structural strength using wattles. When used externally it can be protected with a Lime render or a clay render.[4]

Building with clay has a long tradition in Germany and other European countries. Framed structures (half-timbered houses) from the 12th century, filled with a mixture of clay and straw fibers, still exist.
