Experimental characterizing of liquid water uptake and release – key to understand moisture-induced decay risk analysis
2025 - IRG/WP 25-41020
Wood can absorb water vapour (sorption) or liquid water (capillarity). Moisture from liquid water (rain, spray water) is often a problem for the performance of wood products used in outdoor structures. Wood is prone to biodegradation when is it too moist for too long periods. Experimental studies that allow conclusions to be drawn about the practical use of wood water uptake are limited due to the...

Evaluation of moisture exclusion ability of wood using double-layer outdoor exposure tests
2025 - IRG/WP 25-41021
The material resistance of wood to decay must be due to the combined effects of heartwood extractives and the moisture content state. Evaluating the moisture exclusion ability of wood is important for assessing its durability in outdoor use. We conducted previously double-layer outdoor exposure tests and investigated the relationship between moisture content over time and the progress of decay usi...

A Case Study of Vogvarjeva hiša, a Local Ethnographic Museum
2025 - IRG/WP 25-41027
The Vogvarjeva hiša in Spodnje Duplje, Slovenia, is an example of traditional 18th Century wooden architecture and an important element of the region’s cultural heritage. The building was constructed from local timber on stone foundations and reflects the traditional rural building techniques of the Gorenjska region. Since it was declared a cultural monument in 1985, it has functioned as an eth...

A multi-dataset validation study of moisture prediction in Norway spruce wood exposed outdoors
2025 - IRG/WP 25-41029
Wood used in outdoor construction undergoes continuous cycles of wetting and drying, resulting in fluctuating moisture contents that directly influence its long-term durability. Excess moisture above a critical threshold leads to deterioration by fungal decay, limiting the service life of the structure. Service life models thus rely on accurate predictive models of moisture behaviour. However, cap...

Relationship between changes inside moisture content of wood measured using temperature and humidity sensors and swelling and shrinkage
2025 - IRG/WP 25-41030
With the spread of mid and high-rise timber buildings, the long-term use of timber buildings is getting required more than ever. It is considered that measurement of the local inside moisture content of a wooden member is one of the useful methods for periodic health assessment of timber buildings. The aim of this research is to establish an easy estimation method of the local inside moisture cont...

Linking treatability with moisture dynamics
2025 - IRG/WP 25-41031
Wood preservation is inherently linked to the ability to penetrate treating liquids. The EN 147374 (2022) standard provides a methodology to assess treatability and allows to identify wood species in relation to treatability classes. Over the past decades, performance of wood species in applications in use class 3 has been linked both to the impact of moisture dynamics and the resistance against f...

Investigation of Pressure-Treated Foundations with Wood Preservative and Termite Control in Existing Wooden Houses in Japan
2025 - IRG/WP 25-50402
Japan has extremely limited natural resources. Therefore, it is necessary to build a circular economy in which waste and other recyclable resources are effectively utilized in order to achieve sustainable development. This study aims to investigate the degradation of existing wooden houses and to contribute to the reuse of existing houses and the reuse of building materials during demolition. We i...

Valorisation of bark extractives for wood and plant protection: the Extrabark project
2025 - IRG/WP 25-50415
The Extrabark project is an Interreg collaborative project between Lorraine in France, Wallonia in Belgium, the Saarland in Germany and Luxembourg. The objectives of the project are to develop a complete value chain of valorisation of bark generated by wood industry via the utilization of extracts or molecules for the protection of plants and wood material as a bio-sourced alternative to petrochem...
