Mitigating the risk of decay in CLT buildings affected by trapped construction moisture using a diffusible borate preservative
2025 - IRG/WP 25-20735
Cross-Laminated Timber (CLT) is also known as a mass timber construction material. It is fabricated by gluing together multiple layers of timber lamellae with each layer oriented perpendicular to the one below it. This enhances strength, stability and dimensional rigidity. CLT is seen as an excellent ‘low carbon’ alternative to using steel and concrete and is growing in popularity as a sustain...

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...

Effect of biodiesel-containing solvents on the performance of Copper Naphthenate and Pentachlorophenol: 118-month assessment and depletion analysis
2025 - IRG/WP 25-41022
Solvent systems are incredibly important in determining the performance of oilborne wood preservative systems and they can cause early failures in commodities treated with an otherwise effective preservative system. It is important to assess new solvent performance with oilborne preservative systems to ensure these systems continue to function with the changes. One solvent/preservative combination...

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...
