Moisture penetration into the building structures of residential buildings is caused by climatic conditions and has a negative impact on the operation of buildings. Since thermal insulation of structures directly increases the energy saving of buildings, it can also affect the energy saving of buildings, contribute to the durability of enclosing structures, reduce condensate zones, and reduce fuel consumption during measures to eliminate penetrating water vapor. Buildings in different climatic zones have different vapor permeability rates, which can have different effects on the physical condition and thermal properties of surrounding structures. Thermal insulation significantly reduces the intensity of thermal conductivity and heat transfer processes, reduces air and moisture permeability. The main goal of this study was to determine the construction the amount of steam passing through the structure due to its vapor permeability and its impact on the thermo-humidity regime of the building. The thermal and air-humidity conditions of two types of buildings widespread in the Republic of Armenia, 5-story tuff and 9-story RC panel cladding structures, were observed in different climatic zones of the republic. It has been proven that the type, thickness and installation method of thermal insulation material have different effects on the formation of condensate zones in external structures for different settlements of the Republic of Armenia. As a result of the research, it was found that in tuff cladding structures (in the cities of Yerevan, Gyumri, Hrazdan, Vanadzor and Sevan) a condensate zone forms, while in Kapan it does not. However, by using different types of thermal insulation materials, such a phenomenon can be avoided. Studies have shown that in order to ensure the required thermal resistance and avoid condensation in the mentioned cities, it is necessary to use a thermal insulation material with the minimum required thickness. The thickness of the foamed polystyrene thermal insulation layer in buildings with a tufa structure is: In Yerevan and Vanadzor - 5 cm, in Gyumri - 6 cm, in Hrazdan and Sevan - 7 cm, in Kapan - 4 cm, and in expanded polystyrene - 6 cm in Yerevan and Vanadzor, 8 cm in Gyumri, Hrazdan and Sevan, and 5 cm in Kapan. In the case of reinforced concrete panel construction, the thickness of expanded polystyrene will be 9 cm in Yerevan, 10 cm in Vanadzor, 11 cm in Gyumri, Hrazdan, and Sevan, and 8 cm in Kapan, in the case of expanded polystyrene։ 7 cm in Yerevan, 8 cm in Vanadzor, 9 cm in Gyumri and Sevan, 10 cm in Hrazdan, and 7 cm in Kapan.
