Abstract

Samples of cob earth-walling of the type used in vernacular buildings in the West Country region of the United Kingdom and thought to be of significance from both structural and historic points of view, have been assessed. The compositions of the samples were as expected. A transient thermal-probe technique was used to determine the thermal conductivities (~0.6W/mK) of the samples in their normally-moist state.Their specific heat capacity, for an average moisture content of 3%, was -891 J/kgK. Nomenclature C Specific heat capacity of the cob material (J/kgK). k Apparent thermal conductivity of the cob material, (W/mK). PVC Polyvinylcloride
