The impact of additional interior layers to the moisture dry-out and mould growth risk of CLT walls
2019 - IRG/WP 19-40876
The objective of this study was intended to determine the maximum allowable initial moisture content for CLT walls having both exterior and interior thermal insulation. A laboratory test was conducted, for which four test walls with two different insulation solutions and two different initial moisture contents were built. Based on the test results a simulation model was configured and simulations ...

Real-Time PCR Assays for the detection of the dry rot fungus Serpula lacrymans and its close relative Serpula himantioides
2016 - IRG/WP 16-10867
Prevention of wood decay by fungi of the phylum Basidiomycota is an important issue of wood protection. The most destructive fungus in buildings in Central Europe is the dry rot fungus Serpula lacrymans, which needs more extensive restauration measures than all other wood decay fungi. Its close relative S. himantioides occurs more frequently in outdoor environment. The assessment and remediation o...

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...

Reuse of discarded wood and alternative wood species to replace spruce in the development of wooden windows for complete disassembly – REWINNUSE
2023 - IRG/WP 23-30785
The REWINNUSE project focuses on the reuse of discarded wood and alternative wood species and on the development of wooden windows that can be easily disassembled into their basic components. In cooperation with the project partners (M Sora, the University of Ljubljana Biotechnical Faculty (BF), the Norwegian Institute of Bioeconomy - NIBIO and the Slovenian Forestry Institute (GIS)), the project ...

Phytosanitary treatment of roundwood for oversea shipping - on the suitability of dry heat treatment as alternative to climate-change effective fumigation
2024 - IRG/WP 24-50394
The transcontinental trade of roundwood requires thorough phytosanitary treatment to protect native flora and fauna against foreign pests. This is generally done by fumigating shipping containers packed with roundwood with sulfuryl fluoride, a potent greenhouse gas. After treatment, the gas is released into the atmosphere, causing massive emissions. Since 2017, the usage of sulfuryl fluoride in th...

Neglected Contribution of Herman Schacht on Soft Rot in 1863 Revisit to “wet rot” and “crystalloid holes in spiral directions
2025 - IRG/WP 25-11054
The term “soft rot”, characterising a specific type of wood decay, was established in the mid-20th Century by John Savory (1954). This decay involves cylindrical cavities formed by Ascomycetes and Fungi Imperfecti within secondary cell walls of wood, aligned with cellulose microfibrils. However, similar features were described already 160 years ago by the German plant anatomist Hermann Schacht...

From Wet to Preserved: Collecting Data of Waterlogged Wood Treated with PEG in Lanyan Museum and Study the Effect of Molecular Weight on Dimensional Stability
2025 - IRG/WP 25-11080
Waterlogged archaeological wood are most commonly unearthed in Yilan County, with over one-third originating from the Yilan Agricultural School site. This study aims to analyse the current state of conservation of waterlogged archaeological wood in Yilan County and hopes to properly alleviate the irreversible damage caused to the waterlogged archaeological wood after they leave the water layer. Ho...

Improvement and practical application of dry-type pressure treatment method
2025 - IRG/WP 25-20734
In years, the need for environmental consideration has been reaffirmed worldwide, and in Japan too, there is a demand for the expansion of the uses of wood in order to achieve a decarbonised society. So, there is also a need to develop and improve wood preservation treatment methods that overcome the weaknesses of wood and enable it to be used in a wide range of applications. The authors have impr...
