In this paper, the thermal dynamic characteristics of exterior walls with variant concrete solutions of load-bearing layer were analysed. The main aim of this study was to compare the amplitudes of wave fluctuations of internal temperature and internal heat flux depending on the construction material used. Calculations were made for partitions with a structural layer made from lightweight concrete composites, autoclaved aerated concrete and reinforced concrete. Very good damping properties were obtained for the partitions made of concrete composites. The obtained data suggests that such solutions provide much smaller fluctuations of temperature and heat flux in comparison to materials with low specific heat.
