Thermophysical properties of aerated concrete and phenolic foam were investigated by the pulse transient method. Effects of contact area and heat losses from the free specimen surface were noted. Optimisation of specimen geometry to ensure data stability is discussed. A procedure is described for correcting heat loss effects from the specimen surface. Thermophysical properties of the two porous materials were measured in various surrounding atmospheres.
