MODELING OF THE CONDITIONS OF OPERATION OF THERMAL INSULATION MATERIALS IN THE COMPOSITION OF FACADE SYSTEMS

Abstract

To simulate the operating conditions of the main types of heat-insulating materials as part of various facade systems, an experimental stand was designed and installed. Sampling of heat-insulating materials was carried out to establish the operating humidity after the summer period and in the late autumn period of the year at the beginning of the heating period. It is shown that the modeling of flooding in the zone of the wall joint with the ground, significantly affects the values and nature of the distribution of operating humidity inside the insulation layers. By monitoring the parameters that determine the heat-shielding properties of the enclosing structures, it was concluded that the soil in the interface zone with the wall as a result of freezing in the cold period of the year does not improve the thermal protection characteristics of the building barrier, therefore this design zone requires insulation. Confirmed the correctness of the changes in the regulatory documents relating to the studied issues.
