In this paper an innovative prefabricated composite wall construction blocks made of concrete with polyurethane inserts was investigated. Two different and separate numerical analyzes were performed i.e. thermal and dynamic analysis, respectively. At first the dynamic numerical analysis was performed to estimate the damping ability of disturbance wave propagation in the composite block in relation to the solid concrete model. Such disturbance propagation was assumed as a result of an explosion blast located at certain distance from the considered wall. Secondly the thermal conductivity analysis for both models was performed. In order to perform such numerical analyzes the ADINA program was chosen. All computations were performed on three dimensional space models. Performed analyzes allowed to observe if and how much the polyurethane inserts diminish both the heat flow and wave disturbance propagation.
