The article presents the results of a set of hygrothermal experiments of an external wall insulated with an ETICS. As an add-on to previous studies, thermal insulation in the form of polystyrene with an additional horizontal strip of mineral wool was used. Laboratory tests were carried out in accordance with ETAG 004. The ETICS test rig was composed of combustible expanded polystyrene foam (EPS) and horizontal strips of noncombustible mineral wool (MW) fire barriers over windows. The physical and mechanical properties of four types of finishing renders (without an additional reinforcement mesh in base coat of the fire barriers) were analyzed across full hygrothermal cycles in a climate chamber. Temperature sensors were mounted onto different ETICS layers to collect thermal data during the weathering. The testing of ETICS regarding their hygrothermal performance revealed that there were no visible defects on any renderings and over the junctions depending on the type of used insulation materials. Results also showed that the joints of EPS and MW have approximately half of their bond strength from polystyrene strength.

This paper presents a case study on how to improve the energy efficiency of an institutional building of significant heritage value through retrofitting the external wall system. This building is located in Upper Silesia, Poland. Due to the architectural value of the facade, thermal insulation had to be applied from the inside. As part of this publication, basing on the measurements and simulations, the authors present the results involving the improvement of energy efficiency of the insulated wall. On this basis, they also demonstrate the impact of insulation from the inside on the change of humidity inside the room. The tests were carried out both quantitatively by means of heat flux measurement and qualitatively by means of infrared temperature measurement. The research was supported by numerical modeling. The obtained results indicate that the thermal insulation used in the form of mineral insulation boards applied from the inside improves thermal insulation of the wall. Thus, heat losses through the examined envelope were limited. Computer simulations indicated that no condensation may occur under the condition considered.

This paper is the research output of the laboratory ageing of external thermal insulation composite systems (ETICS). This was carried out in order to study the changes in properties of systems consisting of combustible and non-combustible thermal insulation materials, and four different types of finishing renders. Four types of the widely used, thin-layer facade rendering systems were subjected to hydrothermal cycles in a climate chamber in conformity with ETAG 004 guidelines. Analysis of the physical and mechanical properties (i.e., variation of temperature, water absorption, bond strength and mechanical resistance) of four types of ETICS are presented. This study indicates that there are no visible defects on any renderings over the junctions between polystyrene foam (EPS) and mineral wool (MW) materials when applied in ETICS.

This article presents the research studies aimed at identifying the behavior of expanded polystyrene with the addition of graphite in the conditions of exposure to solar radiation. For this purpose, a series of in situ tests and laboratory studies were carried out. Three types of material were tested, i.e. expanded polystyrene (EPS) (white polystyrene), polystyrene with the addition of graphite (gray polystyrene) and two-layer polystyrene (gray bottom layer and white top layer). Temperature distributions on the surfaces of the panels in field and laboratory conditions were determined. The distributions of temperature were recorded at varied wind impact (field conditions and laboratory conditions) and at varied impact of solar radiation (laboratory conditions). Based on the conducted experiments, differences in temperature distribution on the surfaces of the tested panels were determined. In addition, geometric changes and deformation levels of the tested white and gray expanded polystyrene panels exposed to artificial sun radiation were determined in laboratory conditions.

The article presents the problem of damage to historical balconies, having other structural or material solutions than the modern ones. Their durability and maintenance aspects comprise a wide spectrum of issues, including repair and renovation methods, selection of new materials for the existing structures and their mutual interaction. The applied solutions must take into account the specificity of the components, their performance in the conditions of external environment, the impact of variable temperatures, both positive and negative ones (including, in particular, zero-crossings), atmospheric precipitation or solar radiation. Particular attention was paid to balconies with steel and ceramic structure, whose technical diagnostics should include, apart from structural analysis, also detailed observations of heat and mass transfer phenomena. The paper presents the results of numerical analyses for twodimensional models, similar to the actual structure of the historical envelope (both for the original state and after the performed thermo-modernization works) as well as the results of thermographic measurements of one of residential buildings with balconies with steel beams. In the adopted boundary conditions, the local climate was taken into account, based on the data from the nearest meteorological station. The present objective involved the acquisition of qualitative results. The obtained results comprised: the distributions of temperature fields in cross-sections, distribution of heat flux density changes, and temperature values in selected cross-section locations. The research confirmed the expected tendencies in temperature distributions in the envelope, the location of local thermal bridges and the zones of their impact. Further analyses should be continued on the obtained changes in heat flux density, both in the steel beam support node, as well as in the joints and bricks in the adjacent layers. These places overlap with the actual occurrence of loose and weakened mortars in the building walls and in ceramic tiles. In further analyses, simulation programs facilitating the determination of the amount and changes of moisture in time should be applied.
