Original Abstract

Thermal insulation is an integral part of almost all modern buildings. An important aspect in this process is the elimination of thermal bridges and insulation of all structures which are exposed to adverse environmental conditions. We are increasingly encountering thermal insulation solutions for elements that have been neglected in the past. One of these constructions is the substructure, which means not only the foundations, but underground floors and plinth. These constructions must be insulated with a material which not only has suitable thermal-insulating properties, but also has to withstand the effects of moisture in the long term. Nowadays, expanded polystyrene with a closed outer structure has become one of the most commonly used thermal insulators for these purposes. However, it is clear that, when built-in, the outer structure of the envelope is often damaged. This is often neglected phenomenon, which has a negative effect in the amount of diffusion flow and moisture propagation in the material. This paper describes a laboratory experiment, in which the outer structure of the EPS samples was broken in various ways. The samples were then fully immersed in water, changes in mass and volume absorbency over time were recorded and results were reciprocally compared.
