Light Straw Clay in Uckermark

Light Straw Clay in Uckermark was a 4-day workshop I attended in the Uckermark region of Germany taught by renowned architect, earthbuilding specialist and author Franz Volhard. Light Straw Clay is a time tested, owner-builder-friendly technique for insulating walls and roofs. Clay is stirred up with water and mixed with long straw to create a building material with a dry weight of around 1000 kg per cubic meter. With a relatively high proportion of clay, the material has high strength and elasticity and is easy to place into wall and ceiling cavities. For more information on this technique I highly recommend ordering a copy of Franz Volhard's book Light Earth Building.
