Moisture Detection in Timber Building Structures Using the Passive Moisture Point Method

24.2.2025 | Ing. Luděk Liška
Moisture affects the strength of wood. The strength decreases with increasing humidity. Excessive moisture in wood allows the growth of wood-decay fungi. They attack the building covertly and can cause great damage before they are detected. Wood can be protected against wood-decay fungi by impregnation. Its use in residential buildings is problematic. That is why structural protection is used, i.e. incorporating the wood into the building in such a way that it does not get wet or even soaked and its natural drying out is ensured. During the lifetime of a building, timber can be threatened by high humidity in the structure, condensation, water vapour, leakage or failure of water supply systems and, for example, flooding. It is wise to measure the moisture content of timber in structures and to react in good time to excessive moisture content. Unfortunately, there are not many ways to do this. The method described in this article addresses the monitoring of moisture in timber enclosed in structures.

The envelope of modern buildings not only serves an architectural and aesthetic function but also creates a shell that ensures the quality of the indoor environment. The cladding protects the interior from weather influences and must also meet high demands for thermal insulation properties. An important criterion is the strength and safety of the facade anchoring system to the load-bearing structure of the building. If this system is not sufficiently rigid, it can lead to the opening of joints, which disrupts the watertightness and airtightness of the facade. In the event of system failure, it can even result in the entire facade element falling out. This article follows up on the previous one, which dealt with metal system anchors - brackets that are primarily used for securing window frames into openings. It describes the procedure for experimentally verifying the resistance of a more massive type of heavier anchoring intended mainly for protruding lightweight facade systems.

The cladding of buildings not only has an aesthetic and architectural function, but also forms a very important protective envelope of the building, which ensures the quality of the indoor environment. The cladding protects the interior from the weather and at the same time must meet high requirements for thermal insulation properties. Another important criterion is the strength and safety of the anchoring system of the individual elements of the façade to the building structure. If this system is not sufficiently strong, the joints may be torn apart, which will compromise the watertightness and airtightness and cause a gradual degradation of the quality and performance of the structure. In the extreme case, failure of the fixing system may result in the entire façade element falling out and endangering lives.

Thermal Properties of Double Window and Modern Construcions Jamb

20.3.2023 | Ing. Lucie Kudrnáčová, Ph.D, ČVUT v Praze, Kloknerův ústav, Oddělení stavebních materiálů
The paper deals with the comparison of the thermal properties of jamb for different types of windows. In the case of reconstruction, it is often necessary to preserve the original double- windows or to use modern materials due to the thermal solution of the building. Modern constructions mean the use of double or single windows with thermal-insulating glazing. These changes in the construction of the window have an effect on the thermal processes on the structure. One of the important parameters for the assessment of the building structure is the assessment of the internal surface temperature of the building structure. This article shows the difference in finishes and heat flows to remove different types of windows. The reference window for comparison is the original double history window. The results were found in a model environment in 2D software.

The protection of wood in wooden buildings does not seem to be very important due to their location in use class 1 or 2 according to ČSN EN 335, but it is particularly suitable for timber elements that are located close to the foundation slab or are difficult to replace. It follows from the majority of recurring defects, for example plumbing failures, leaks through the roof, facade, inappropriate terrain height around the base plate or as a result of a tornado, that it is necessary to protect at least the foundation threshold according to the structure of the wooden building, preferably up to use class 4 according to ČSN EN 335, which is only possible by pressure impregnation.
