“The Hempcrete Book is the comprehensive, practical new book about building with hempcrete: a natural building material made from the chopped woody stem of the hemp plant (hemp “shivs”) and a lime-based binder. It is a non-loadbearing, sustainable, ‘breathable’ (vapor-permeable) and insulating material that can be used to form walls, floor slabs, ceilings and roof insulation in both new builds and restoration projects.
