mpact of Fence Post Footings on Wood Post Durability
2025 - IRG/WP 25-41025
Residential wood fence posts may be dug directly into the ground, secured to a metal spike that goes into the ground, or secured to a concrete footing with a metal boot. It was hypothesised that by keeping wood posts out of the ground both spikes and boot attachments would increase protection against decay and termites and extend the service life of the post. After 9-years of exposure in Kincardin...

Fungal decay in cable car pylons in Svalbard - overview of results
2025 - IRG/WP 25-41026
A total of 212 iconic wooden cable car pylons were constructed for mining operations in Svalbard, significantly contributing to Longyearbyen's historical identity as a mining town. Fieldwork in Svalbard involved collecting wood samples from 22 of these pylons, targeting wood exposed both aboveground and ground proximity. Whilst the timber used in the constructions was assumed to be untreated Norwa...

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...

Validation of a measurement method for cyproconazole retention in pressure-treated wood through an interlaboratory study
2025 - IRG/WP 25-41037
The Japanese Agricultural standard (JAS) defines national regulations for preserved wood and wooden materials, in Japan. Traditionally the JAS focused on quality of product, however, the revision of the JAS Act in 2017 enabled standardisation of test or measurement method for the quality evaluation. The Japan Wood Protection Association (JWPA) has been working toward standardisation of methods for...

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...

Considerations on how different preservation processing methods of logs would have different effects on wood structures
2025 - IRG/WP 25-41040
Azekura-zukuri style wood structures (hereinafter referred to as azekura-style structures) have been utilized in forest conservation projects in Japan as substitutes for concrete structures. We estimate that making use of thinned and small logs for azekura-style structures has positive impact on circular economy and carbon fixation and contributes to the biodiversity within their areas. In additio...

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...

WoodStock: Empowering climate-smart, circular, and zero-waste use of underutilized wood from the forest and building stock in the construction sector to support the New European Bauhaus
2025 - IRG/WP 25-50405
There is a clear need for enhanced contribution of the forest-based sector to decarbonisation strategies for buildings, both in terms of operational emissions, embodied emissions, and carbon removals. WoodStock is a multifaceted project dedicated to advancing climate-smart wood construction practices in alignment with the New European Bauhaus (NEB) initiative. A primary focus is the quantification...

Hyperspectral imaging in qualitative and quantitative assessment of biocide treated timber
2025 - IRG/WP 25-50407
A hyperspectral camera operating in the shortwave infrared light range between 1000 – 2500 nm was used to collect spectral profiles of timber treated with different biocides and varying concentrations of a copper-ethanolamine based wood preservative. The spectra were analysed using statistical methods like principal component analysis, linear discriminant analysis, and partial least squares to a...

Contribution of naturally durable wood use to Circular Economy - Understanding the classification system of natural durability and its variation within wood species
2025 - IRG/WP 25-50411
Total wood demand is shown by FAO to increase 49 percent between 2020 and 2050, regardless of deteriorating conditions such as deforestation and degradation due to fire and biological damages. Demand for wood as a building material is also projected by UNEP to increase significantly to 300 Gt in 2040. To address this situation, extension of the service life and re-use of wood are expected to make ...

Physical and chemical characterization of post-consumer wood chips for recycling
2025 - IRG/WP 25-50414
Post-consumer wood (PCW) is a valuable resource that can partially substitute virgin wood in material applications. This communication paper presents key findings from a study that analysed PCW collected from three recycling facilities in southeastern Norway over eight months. A total of 20 mixed and 4 pre-sorted PCW samples were evaluated regarding their material composition, particle geometry, a...

Probing nanoscale protection mechanisms with x-rays and neutrons
2025 - IRG/WP 25-11083
While it is known that exposing wood to high levels of moisture, fire, or decay agents such as fungi can be detrimental for its performance, what is often missing in literature is a holistic understanding of how wood nanostructure changes due to these exposures. This is of particular interest since treatments that are meant to impart resistance can alter these length scales and/or modify their hyg...

Analysis of A Wooden Structure Damaged in a Fire – The Wooden Granary at Zaprice, Kamnik
2025 - IRG/WP 25-41049
Zaprice Open-Air Museum in Kamnik, Slovenia, features several granaries dating to the early 19th century, forming part of the national Cultural Heritage Register (EID: 1-09881). One of the two-chamber wooden granaries, constructed in 1828, suffered significant fire damage in December 2024. The objective of this study was to evaluate the extent of the damage, assess the structural integrity, and id...
