摘要：

The paper presents the results of in-situ research studies and hygrothermal simulations for a fragment of prefabricated cellular concrete wall, insulated with Styrofoam, allowing for two types of external plasters. The disruption of heat and mass transfer is effected by the connector for thermal insulation mounted in the layer of cellular concrete. The carried out research studies and simulations have demonstrated that the impact of the insulation connector with a steel core is observed only locally, but its destructive impact should not be ignored.
