Durability and service life of wood in constructions. The Spanish approach of European Standard EN 460
2025 - IRG/WP 25-41028
The durability of wood is an important factor to be considered in the construction influencing in final durability and expected service life of a wood product in construction. There are many factors influencing in the durability (service life) of a wood in construction: Natural durability of wood species, preservative treatments and protection by design; combined with the variability of environmen...

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...

Preliminary assessment of imidazole as an adhesion system for particleboards
2025 - IRG/WP 25-41043
Particleboards with different combinations of adhesive mixtures containing imidazole, citric acid, and sorbitol were produced. Softwood sawdust from a Swedish sawmill was mixed with an aqueous solution of the chemicals and then dried to 0% moisture content prior to pressing. The boards were pressed to a target density of 700 kg m−3 at either 200 °C or 220 °C for 10 min. The hygroscopic and mec...

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...
