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...

Durability and service life of wood in constructions. The Spanish approach of European Standard EN 460
2025 - IRG/WP 25-41028
The durability of wood is an important factor to be considered in the construction influencing in final durability and expected service life of a wood product in construction. There are many factors influencing in the durability (service life) of a wood in construction: Natural durability of wood species, preservative treatments and protection by design; combined with the variability of environmen...

Durability evaluation of outdoor-exposed CLT treated with various wood presevatives using CT scans
2025 - IRG/WP 25-41035
Methods for wood preservation treatment of large materials such as Cross Laminated Timber (CLT) are limited. It is unclear which wood preservation treatment methods can effectively protect CLT from rot risk. In this study, accelerated rot tests (fungus cellar test) of CLT treated with the solvent-borne wood preservative by non-pressure treatment, named ‘deep penetration treatment’, were conduc...

Quantitative Prediction of Latent Deterioration in Wood Coatings Using Mid-Infrared Spectroscopy and Machine Learning
2025 - IRG/WP 25-41038
Wood coatings play a vital role in prolonging the lifespan of timber structures by protecting them from environmental degradation. However, conventional evaluation methods rely on visual inspections, which cannot detect latent deterioration before visible damage occurs. This study integrates attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy with partial least squares ...

Non-destructive methods for field assessment of wood biodeterioration in hardwood trailer decks exposed to tropical environments
2025 - IRG/WP 25-41039
Apitong (Dipterocarpus spp.), an increasingly rare tropical hardwood from the rainforest in Southeast Asia, has long been used as decking materials for open-bed trailers and trucks across North America. As the natural population of Apitong trees steadily declines, there is an urgent need to find sustainable, domestically sourced alternatives for trailer decking. A recent project evaluated the perf...

Development of an Early Degradation Diagnosis Technology for Wood Coatings Using Mid-Infrared Spectroscopy and Machine Learning
2025 - IRG/WP 25-41047
Accurately predicting the degradation state of wood coatings is challenging, and as the coating deteriorates, it becomes a major factor accelerating the degradation of the wood itself. In this study, we aimed to develop a diagnostic technology that combines mid-infrared spectroscopy and machine learning to assess latent coating degradation, which cannot be detected visually, and to enable appropri...

Durability Enhancement of US Hardwoods for Use in Open Trailer Decks
2025 - IRG/WP 25-41048
Apitong, a tropical hardwood derived from endangered species within Dipterocarpus genus, has long been used as a decking material for open flat-bed and lowboy trailers in the U.S. However, as more Dipterocarpus species are classified as endangered and critically endangered by International Union for Conservation of Nature (IUCN) due to the declining population of Apitong trees, there is a growing ...

Contribution of naturally durable wood use to Circular Economy - Understanding the classification system of natural durability and its variation within wood species
2025 - IRG/WP 25-50411
Total wood demand is shown by FAO to increase 49 percent between 2020 and 2050, regardless of deteriorating conditions such as deforestation and degradation due to fire and biological damages. Demand for wood as a building material is also projected by UNEP to increase significantly to 300 Gt in 2040. To address this situation, extension of the service life and re-use of wood are expected to make ...
