The advantages of autoclaved aerated concrete (AAC) masonry in terms of thermal properties and affordability have already been widely discussed. Nowadays, we are able to achieve the required thermal resistance of facades without the need to apply an external thermal insulation composite system on the entire surface. Decreasing the heat transfer coefficient is usually associated with increasing the proportion of pores in the material. However, this in turn adversely affects the sound insulation properties of simple partitions. Therefore, in effort to achieve the specific acoustic requirements of simple masonry AAC walls, structures of unacceptable thickness in practice may be designed. In this paper we present a study focused on the analysis of the dependence of the heat transfer coefficient resp. thermal resistance of structures and airborne sound insulation of simple walls based on AAC.
