EMC as a quality control parameter for thermally modified wood
2024 - IRG/WP 24-20720
While standards for quality performance of treated wood have been in place for many years, none have been developed for modified wood such as thermally modified wood (TMW). Only in one case has TMW been listed in 2018, by the Nordic Wood Preservation Council (NWPC).
A key component of a quality system is its control parameters, i.e. the metrics that are to be measured and controlled. Existing m...

CIOL Wood – Industrialization of Sustainable Wood Products: Progress and Prospects
2025 - IRG/WP 25-30820
CIOL® is an innovative, low-cost, non-toxic wood modification system designed to replace traditional, non-sustainable treatments used for wood protection. Since our last contribution in 2023, significant progress has been made in the development of CIOL® towards industrial-scale production. This update presents new results on fire protection, mechanical properties, and the continued scaling of t...

Process Development in Continuous Wood Densification and the Influence of Ionic Liquids on Set-Recovery and Mechanical Properties
2025 - IRG/WP 25-30827
The densification of wood significantly enhances its mechanical properties, making low-density species more viable for high-performance applications. However, challenges such as set-recovery (SR) and production speed hinder large-scale adoption. This study investigates continuous surface densification using a custom-built belt press and examines the effect of chemical pre-treatment with ionic liqu...

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...

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...
