A Conceptual Review of Young People’s Perceptions about Wood
2018 - IRG/WP 18-40836
This article was adapted from the previous study “Young People’s Perceptions about Wood” prepared by Usta (2017), and extended through the development and evaluation of the initial data in terms of the conceptual framework regarding the descriptions of wood by young people. Because it was highlighted by previous study that the university students as the full members of society have the aware...

Quantifying the effect of microclimatic parameters on the moisture-induced decay risk of wooden structures
2019 - IRG/WP 19-20649
Wood exposed outdoors is prone to fungal degradation. Besides its material-inherent resistance, numerous factors are impacting on its service life with both, climate and design having a major effect. In addition, topography, shading, wind barriers, and other local parameters have an effect on the microclimatic conditions at site and therefore need to be quantified for service life prediction of wo...

Impact of water holding capacity and moisture content of soil substrates on the moisture content of wood in terrestrial microcosms
2019 - IRG/WP 19-20662
Terrestrial microcosms (TMC) are frequently used for testing the durability of wood and wood-based materials as well as the protective effectiveness of wood preservatives. In contrary to experiments in soil ecology sciences, the experimental set-up is usually rather simple. However, for service life prediction of wood exposed in ground, it is of immanent interest to better understand the different...

Monitoring of the building made of CLT in Ljubljana
2019 - IRG/WP 19-40860
Wood is one of the most important construction materials and its use in building applications has further expanded in recent decades, predominately due to development of the modern composites, like cross-laminated timber. In order to enable even more extensive and reliable use of wood in outdoor applications, factors affecting wood’s service life need to be understood. It is well known that fung...

Impregnation of railway sleepers - Investigation of a system-sleeper as an alternative for creosote treated sleepers
2020 - IRG/WP 20-40896
For nearly 200 years wooden railway sleepers are impregnated with creosote. After initially using vacuum pressure processes for impregnation, empty-cell processes have been developed quickly and are used until today. Because of political developments, creosote will probably be banned on the European market in the near future. The Fürstenberg-System-Sleeper, which combines for Europe innovative as...

Effect of Moisture Cycles and Timber Treatment on the Performance of Screwed Connections
2023 - IRG/WP 23-20694
The impact of moisture in timber structures is associated with the deterioration of timber, and loss of mechanical performance. Methods have been developed to treat timber using chemicals to inhibit deterioration, however, water intrusion has much more immediate effects on the mechanical properties of timber associated with swelling and shrinkage of the wood. The effects of moisture on the mechani...

Moisture performance of wooden shingles tested on the Golobar cable yarding
2023 - IRG/WP 23-20704
Wood is a traditional roofing material in Europe and other parts of the world. In the 17th century, wooden roofing was generally used on more important buildings, but today it is mainly used on huts and houses in the Alpine regions. As wooden roofing is expensive, we investigated the possibility of extending the service life of the roofing through material selection and details. The roof of the Go...

How personality traits influence the perception of fungal decay in a wooden cladding – A survey in three Modelling wood moisture content in outdoor conditions from measured data
2024 - IRG/WP 24-41002
This study examined perceptions of fungal decay damage on wooden cladding across Norway, Sweden, and Germany. The majority of respondents across all countries did not find the fungal decay damage in question acceptable, with the least acceptance in Norway. This could be due to Norway having the highest frequency of wooden residential buildings and the most experience with maintaining wooden claddi...

Modelling wood moisture content in outdoor conditions from measured data
2024 - IRG/WP 24-41005
Sustainable use of wood requires an understanding of expected service life, particularly when the material is exposed to outdoor conditions and, thus, fungal decay. Since moisture is the primary vector for fungal decay, accurate moisture prediction is a key component in service life assessment. For this purpose, the present study leverages existing measured data for linear regression of in-field m...

Analysis and performance of spruce alternative species and discarded wood for windows production
2024 - IRG/WP 24-50386
Climate change is having a significant impact on European forestry, particularly on the softwood species used for window frames. This study investigates potential replacement tree species for spruce (Picea abies), the predominant material for window frames. We evaluate Douglas fir (Pseudotsuga menziesii), Scots pine (Pinus sylvestris), thermally modified poplar (Populus nigra) and discarded silver...
