The paper presents a comprehensive theoretical study of the external fencing structure made of innovative Porortherm 38 ceramic blocks in comparison with traditional structures made of solid ceramic brick, hollow ceramic brick and gas block. The study was conducted in the climatic conditions of Shymkent city, South Kazakhstan. The middle temperature values of the frostiest 5 days with a provision of 0,92 were adopted as the external temperature. The results of the study of the actual resistance (Rf) of the structures under study showed that all adopted structures meet the condition Rf˃Rreq, while the actual resistance of the new structure is 1.3 times more efficient than traditional ones. The analysis of temperature fields showed that the new structure is 2% more efficient than traditional ones. Moreover, no additional insulation costs are required. The obtained results were also confirmed by computer modeling in the ELCUT software package. The results of calculating the humidity regime showed that a condensation area appears in almost all the structures under consideration. The results of calculating the amount of moisture evaporated from the multicoat structure of the external fencing during the torrefaction period showed that all the accumulated moisture will evaporate during the specified period, the calculation of the condition of inadmissibility of moisture accumulation in the structures of external fencings for an annual period and for the period of moisture accumulation showed that all the considered structures meet the requirement . The results of calculating the air regime of multicoat structures of external fencings also showed that all structures including the new one meet the condition . The result of calculating the value of thermal inertia (D) in the proposed structure is up to three times more efficient than traditional structures, which applies to structures with high inertia (7˂D). The obtained results of the study indicate that the new proposal of a structure made of ceramics is cost-effective, innovative blocks can be proposed as a supplement to the register of materials of existing standards.
