A comparison of methods – how to achieve a robust and conclusive durability classification of wood
2025 - IRG/WP 25-11063
The biological durability of wood is a relative and unitless size, and therefore wood species and wood-based materials are assigned to durability classes (DC). In Europe, such classes are based on a variety of measures, which can be absolute or relative to a non-durable reference species. The aim of efforts to develop and standardise methods for determining biological durability should be to ensur...

Detecting wood-decay fungi in walls: a non-destructive approach with an electronic nose
2025 - IRG/WP 25-11070
Wood-decay fungi degrade the structural integrity and safety of wooden buildings, leading to potential hazards and reduced durability. Conventional detection methods, such as visual inspection and destructive sampling, are often impractical for concealed spaces, such as those within walls or beneath floors. These methods often require specialised training and costly equipment, making non-destructi...

Evaluating the Efficacy of Arnica Extract-Based Termiticide from Berkem Biosolutions® in Subterranean Termite Control: A Comprehensive Laboratory and Four-Year Field Study
2025 - IRG/WP 25-20731
Subterranean termites pose significant threats to wooden structures. This study evaluated the efficacy of a bio-based termiticide product containing Arnica extract from Berkem Biosolutions® in controlling subterranean termites in both laboratory and field conditions. The laboratory assessments utilised “the Bottle H” test unit, adhering to the Japan Wood Preservation Association (JWPA) standa...

Functionalization of wood with nano-sized titanium dioxide – Efficacy against mould growth and effect on cell wall integrity
2025 - IRG/WP 25-20740
Nano-sized titanium dioxide (nano TiO2) is a photocatalytic compound that generates reactive radicals under UV radiation, which can inhibit microbial growth and impart self-cleaning properties. This effect has been widely utilised on materials such as glass or tiles. This study investigates the potential of nano TiO2 treatments to prevent mould growth on wood and their impact on cell wall integrit...

CIOL Wood - Scientific Innovations in Wood Modification for Enhanced Performance and Usage
2025 - IRG/WP 25-20743
CIOL® is a wood modification technology designed as an environmentally friendly alternative to traditional wood preservatives. Utilising a biobased formulation based on sorbitol and citric acid, CIOL® enhances wood's chemical structure, improving its durability, stability, and resistance to decay. This paper provides an overview of the advancements made in CIOL® technology, including its improv...

Enhancing the Effectiveness of Penflufen by using a Plant Booster
2025 - IRG/WP 25-20759
Penflufen (Preventol® A 800) is a modern pyrazole fungicide which has been approved by the US EPA for the use in wood protection in 2018. Penflufen is an inhibitor of the succinate dehydrogenase (SDHI). It is highly efficient against wood decaying basidiomycetes fungi. In the European standard efficacy test EN 113/ EN 84, penflufen is controlling both brown rot and white rot fungi at the low rete...

Novel treatments of solid wood - studies into the use of imidazole and succinimide
2025 - IRG/WP 25-30817
Recent activities have focussed on the use of ionic liquids (ILs) in wood treatments and bioprocessing. Most ILs are based on imidazolium systems, so it was decided to investigate the potential of imidazole as a treatment, along with another heterocyclic compound, namely succinimide. Thus, modification of Scots pine sapwood (Pinus sylvestris L.) with heterocyclic compounds, imidazole and succinimi...

AI Models for Accelerating Wood Protection Testing: Development of Predictive Tools Based on Long-Term Field Test Data
2025 - IRG/WP 25-41023
In this study, we present the development of DecAI, an artificial intelligence (AI) model designed to optimise and accelerate performance evaluations of wood protection products in the European EN 330:2014 "Field test: L-joint method." The Danish Technological Institute (DTI) compiled a dataset of over 100,000 data points from approx.10,000 L-joint samples collected over +15 years at field sites i...

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...

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...
