Impact of Building Walls of Historic Objects from Half-Timbered Wall in their State of Thermal Protection / Wpływ Budowy Ścian Historycznych Budynków z Muru Pruskiego Na Ich Stan Ochrony Cieplnej

Abstract

The paper presents the problems connected with preserved examples of buildings in Upper Silesia that contain the elements of half-timbered walls. This type of construction currently characterizes houses of various utility functions. Often, their formation was related to the construction of patron settlements, accompanied by the development of industrial plants. Today, there is a problem of insufficient thermal insulation of barriers in half-timbered houses and numerous attempts to improve their thermal parameters are observed. In this type of projects, the correct determination of the existing state in terms of construction of the barrier and thermal protection seems to be important, as the starting points for further analysis. The study determines the insulation of frame walls with ceramic fill, with a variety of material and construction solutions. Literature examples and in situ measurements results were used for the research.

Impact of Envelope Structure on the Solutions of Thermal Insulation from the Inside

“…7,8,9) and barriers in the form of polyurethane panels (Figs. 10,11,12) did not raise the water content of the envelope. It should be mentioned that the envelope modeling was carried out assuming full tightness of the external wall (its facade layer).…”

“…The graphs demonstrate (Figs. 8,11) that the water content in the cross-section of wooden element exceeds 100 kg/m 3 and shows a downward tendencydrying out to the level of ∼75 kg/m 3 . With respect to the biodegradation of wood, the moisture content in wood should not exceed 20% of the volumetric weight.…”

“…walls made as a wooden frame with a brick filling, the socalled Prussian walls. Such structures were used at the turn of the 19 th and 20 th centuries also in the present areas of Upper Silesia [11,12]. The objective of this publication is to present some selected elements of thermal diagnostics of historic buildings.…”

Zmiany Zawilgocenia Przegród Budynków Historycznych Przy Zadanych Warunkach Klimatu Zewnętrznego

“…13 obrazuje zmiany temperatur w zaznaczonych miejscach słupów drewnianych w jego wnętrzu i w miejscu połączenia z fragmentami ceglanymi. W pracy [4] autorzy zwracali uwagę na występowanie znacznych różnic w gęstościach strumienia ciepła w miejscu połączeń tych materiałów i występowanie tam szczelin. Przeprowadzone symulacje stwarzają podstawę do przypuszczenia iż miejsca te należy brać pod szczególną uwagę, z punktu widzenia trwałościowego, projektując ocieplenie przegród po stronie pomieszczeń.…”

Selected Problems Involving the Preservation of Historical Frame Buildings in Silesia in the Context of Their Future Thermo-Renewal

“…It is important to consider appropriate performance of wood as a construction material, hygrothermal condition of building envelopes (including also the adaptations of the objects to newly introduced utility functions) as well as their durability and quality of the façade. The performance of historical objects is significantly affected by the issues related to building physics: the influence of internal or external climate, the arrangement of envelope layers in terms of diffusive, thermal properties or tightness [4,5,6,7,8]. All plans to undertake repair, modernization or renovation works, also as part of comprehensive revitalization projects for areas with historical buildings, should be proceeded by a detailed examination of the existing condition, along with the assessment of humidity con- Received: 6.06.2019; Revised: 25.09.2019; Accepted: 6.11.2019 A b s t r a c t The paper discusses the conservation state of selected examples of historical objects preserved in the Silesia Province, having a complex structure with the elements of Prussian wall.…”
