In this paper thermal conductivity numerical analysis of an innovative blocks made of concrete with polyurethane inserts/injects, located in a three-layer wall was performed. Mentioned polyurethane cross pads were assumed to be inserted or injected in specially formed holes in the process of production. Moreover, it was assumed that the wall should meet the conditions of building intended for continuous human presence. In order to estimate the percentage warmth comfort improvement and thermal conductivity the same wall with the use of solid concrete blocks was investigated. On the basis of obtained results one can state that the heat resistance was only slightly improved via the polyurethane cross pads inserts/injects in comparison with solid concrete blocks, whereas measurable benefits could only be observed in the wall without separate insulation layer. Presented numerical analyses were performed with the use of finite element method based software – ADINA program.
