Influence of incising methods and wood moisture content on ‘deep penetration treatment’ in Japanese cedar and larch
2025 - IRG/WP 25-20749
To expand applicability of ‘deep penetration treatment’, a solvent-borne and non-pressure treatment that is commonly coupled with roller-type incising using a flat blade, we investigated drill and laser machining as alternative incising methods and examined the influence of wood moisture content on the preservative penetration. Various incising methods were applied to heartwood of Japanese ced...

Plasma Modification of Basswood Creates Super-Black Wood
2025 - IRG/WP 25-30826
A super-black wood with low reflectivity in the UV/Vis range is created by plasma modifying transverse basswood surfaces. Here the super-black wood is characterised, the process used to make it is described and its possible practical uses are discussed. Wood samples are exposed to oxygen glow-discharge plasma. Transverse surfaces exposed to high-energy plasma have a deep-black velvety appearance. ...

Introduction of UV absorbers to wood surfaces via atom transfer radical polymerization
2025 - IRG/WP 25-30834
Wood is a promising material suited for both residential and commercial construction. However, the structure of the wood materials varies depending on the environmental factors such as microorganisms, water, and light. In particular, wood surfaces exposed to outdoor conditions are rapidly degraded because cell wall chemical components such as lignin structure strongly absorb ultraviolet (UV) light...

Moisture uptake in CLT during the construction phase: real construction conditions versus specimens exposed to environment
2025 - IRG/WP 25-41019
The rapid growth in the use of Cross-Laminated Timber (CLT) in construction highlights the need to address durability concerns, particularly in regions with less experience in Mass Timber Construction and favourable climatic conditions for the biological degradation of wood, such as Mediterranean countries. A lack of awareness and deficient construction management can negatively impact the public ...

Experimental characterizing of liquid water uptake and release – key to understand moisture-induced decay risk analysis
2025 - IRG/WP 25-41020
Wood can absorb water vapour (sorption) or liquid water (capillarity). Moisture from liquid water (rain, spray water) is often a problem for the performance of wood products used in outdoor structures. Wood is prone to biodegradation when is it too moist for too long periods. Experimental studies that allow conclusions to be drawn about the practical use of wood water uptake are limited due to the...

Evaluation of moisture exclusion ability of wood using double-layer outdoor exposure tests
2025 - IRG/WP 25-41021
The material resistance of wood to decay must be due to the combined effects of heartwood extractives and the moisture content state. Evaluating the moisture exclusion ability of wood is important for assessing its durability in outdoor use. We conducted previously double-layer outdoor exposure tests and investigated the relationship between moisture content over time and the progress of decay usi...

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...

A multi-dataset validation study of moisture prediction in Norway spruce wood exposed outdoors
2025 - IRG/WP 25-41029
Wood used in outdoor construction undergoes continuous cycles of wetting and drying, resulting in fluctuating moisture contents that directly influence its long-term durability. Excess moisture above a critical threshold leads to deterioration by fungal decay, limiting the service life of the structure. Service life models thus rely on accurate predictive models of moisture behaviour. However, cap...

Relationship between changes inside moisture content of wood measured using temperature and humidity sensors and swelling and shrinkage
2025 - IRG/WP 25-41030
With the spread of mid and high-rise timber buildings, the long-term use of timber buildings is getting required more than ever. It is considered that measurement of the local inside moisture content of a wooden member is one of the useful methods for periodic health assessment of timber buildings. The aim of this research is to establish an easy estimation method of the local inside moisture cont...

Linking treatability with moisture dynamics
2025 - IRG/WP 25-41031
Wood preservation is inherently linked to the ability to penetrate treating liquids. The EN 147374 (2022) standard provides a methodology to assess treatability and allows to identify wood species in relation to treatability classes. Over the past decades, performance of wood species in applications in use class 3 has been linked both to the impact of moisture dynamics and the resistance against f...

Towards Sustainable Wood Protection: PF resins-impregnated Paper Honeycombs and the role of Processing Parameters analysis by Response Surface Methodology
2025 - IRG/WP 25-41045
Honeycomb paperboard is an important wood-derived product and also an emerging new material to combine with wood panels. It is commonly applied as cushioning materials with excellent mechanical performance, and high demands in packaging market. The aims of this study were to enhance the durability of honeycomb paperboard using PF resins of various molecular weights (Mw 200, Mw 500, Mw 700), partic...

Developing a Novel Bio-based PF Resin as Wood Preservative and Explore its Synthesis Route Using RSM Methodology
2025 - IRG/WP 25-41046
Phenol-formaldehyde (PF) resin treatment has long been recognized as one of the most effective and widely used wood preservation methods, offering exceptional durability, dimensional stability, and resistance against biological degradation. However, traditional PF synthesis relies heavily on petroleum-derived phenol, raising concerns about environmental impact and resource sustainability. To date,...
