The paper presents investigation studies on the historic climate of the interior of St. George’s Church at Ostropa. The church lies on the Wooden Architecture Trail of the Silesian Province within the Gliwice Loop. The building consists of a brick part (presbytery and sacristy) and a wooden part (nave, porch and tower). The shape and size of the church were formed at the end of the 17th century. Most of the decor and furnishings come from that period. Since 2008, the church has been subjected to a wide range of renovation and conservation works. The manager of the object and the conservation office have been entrusted to give special care to the polychromes in the wooden nave, brick presbytery and the main altar. Wooden elements belong to a group of organic hygroscopic materials. They are exposed to the risk of internal damage due to changes in temperature and humidity. The reduction of damage risk involves limiting the scope and dynamics of temperature or humidity changes as compared to the so-called historic climate. The parameters of the historical climate of the object were determined based on the measurement of temperature and humidity inside the investigated object.

This study empirically verified the effect of solar radiation on the building envelope, with particular emphasis on the generated surface temperature. A model of a cellular concrete block wall with ETICS (External Thermal Insulation Composite System) was constructed with varying insulation-plaster configurations, followed by tests in a “sun chamber” aging chamber and numerical analyses. The measurement results were compared with those from the numerical simulations, taking into account the thermal properties of the materials used and the radiation exposure conditions. The purpose of the study was to determine to what extent different types of plasters and insulation materials affect the heating of the façades. Computer simulations confirmed the direction of energy flow and the gradual heating of successive layers. Furthermore, the differences between the material variants were consistent with the experimental observations. By modeling perfectly uniform conditions, the numerical analysis allowed us to limit the impact of radiation variability, resulting in results with reduced error.

This article focuses on aspects related to the physical and thermal parameters of so-called thermal-insulating paints. These materials and systems are used in two different situations: first, as agents reducing surface temperature due to solar radiation, and second, as so-called “thermal-insulating” coatings. The paper focuses on the second aspect of the applications described by the manufacturers and presents the results of the author’s laboratory tests (using an insulated heating box with two different heat sources) and field tests (in situ) on a building façade. The research methodology focuses on contact and thermal imaging measurements to assess the effectiveness and properties of reflective thermal-insulating paints, as well as analyzing their impact on the surface temperature and heat transfer coefficient of building envelopes. The conducted research showed that the use of reflective thermal-insulating paints does not significantly improve the thermal insulation of building envelopes. Measurements of the heat transfer coefficient showed a reduction of 1–7% compared to the reference wall tested. In situ measurements using temperature sensors and thermographic studies confirmed the insignificant impact of reflective thermal insulation paints on the thermal protection of external walls.

W artykule przedstawiono parametry akustyczne pianki natryskowej. Wyniki badań współczynnika pochłaniania dźwięku w komorze pogłosowej wskazują, że ma ona dobre właściwości dźwiękochłonne. Wyniki zweryfikowano przez zastosowanie materiału w pomieszczeniu o przeznaczeniu sakralnym w kształcie kopuły i o kubaturze 14 850 m3. Po zastosowaniu materiału czas pogłosu uległ znacznemu obniżeniu, co poprawiło warunki pogłosowe w pomieszczeniu.
