The influence of climate changes on Central European forests with an emphasis on Slovenia
2022 - IRG/WP 22-50368
When forests are managed sustainably, they play an essential role in protecting climate and biodiversity. They protect soils and water resources, provide livelihoods, and contribute to the well-being of rural and urban communities. European forests are multifunctional and provide a range of ecosystem services. These include the production of renewable materials that can replace materials with a la...

The appropriateness of central one-ninth or core retentions as a means of demonstrating penetration compliance
2023 - IRG/WP 23-40976
Treatment quality is in general terms dependent upon the preservative retention, and how the preservative is distributed throughout the cross-section of the treated article in question, i.e. the penetration of the preservative. Of these two fundamental qualities that are intrinsically linked to treatment quality, penetration is in general terms the most subjective. The determination of retention i...

Recent experiences in the protection of wooden cultural heritage in Europe with a novel wood preservative with vegetal extracts–permethrin-azole mixture
2023 - IRG/WP 23-11027
The paper presents recent treatment experiences in Europe for the preservation of cultural heritage with the bio-based gel-emulsion solution XILIX® containing SYNERKEM® technology, whose higher diffusion capacity has been proven (up to 8 mm pyrethroid penetration into the wood). This gel-emulsion is already authorized and marketed as preventive and remedial wood preservative in Europe for more t...

Time-lapse evaluation of Aureobasidium pullulans growth on selected lignin derivatives and chitosan
2024 - IRG/WP 24-11032
Wood, often referred to as the “building material of the 21st century”, has gained recognition as an attractive alternative to several traditional building solutions. To enlarge the application of wood, several properties including biotic and abiotic degradation resistance need to be improved. Consequently, new solutions are available on the market that ensure expected properties and functiona...

Intra-species variability of moisture dynamics in wood
2024 - IRG/WP 24-11040
Moisture dynamics of wood and wood-based materials play a major role in wood durability against different decay organisms. Their impact becomes particularly evident when wood is exposed, but not permanently wet. To date, however, this has only been taken into account indirectly and therefore inadequately when testing the durability of wood. While test methods are available, for example to determin...

On the use of miniaturized wood specimens in fungal decay experiments – mini-blocks versus EN 113 test specimens
2024 - IRG/WP 24-11044
Preliminary evaluation and classification of wood durability against decay fungi using laboratory monoculture experiments has been a longstanding practice because these tests offer quicker results than field tests. Various methods, including miniaturized specimen formats and different incubation periods, have been explored to expedite decay processes and assess wood preservation efficacy. The 'min...

International joint field trial on the moisture performance of wood – Set up and first results
2024 - IRG/WP 24-40996
Wood durability to decay stems from its inherent resistance to fungi resistance to fungi. In this regard, wood's ability to withstand moisture uptake plays an important role as the lower threshold for wood decay is a moisture content of 25%. However, the aspect of moisture resistance is not yet sufficiently emphasized as a durability factor, both in the assessment of durability as a material prope...

Changes in decay risk of wood in ground contact over Europe, from analysis of historic climate conditions
2024 - IRG/WP 24-41008
Changing climate conditions will affect global temperature and precipitation patterns, shifting some geographical areas into states that are more suitable for fungal wood decay. Climate normals, which are taken over a 30-year period, capture vast spatial and temporal variations in these conditions and comparing these can show changes over time. Importantly, being able to identify locations that ha...
