Laboratory durability testing of preservative treated wood products – first attempts and observations
2023 - IRG/WP 23-20697
In the past, durability classes (DC) had been assigned to wood species, sometimes also to homogenously modified wood-based materials such as thermally modified wood. More recently, some standards allow for classifying the biological durability of chemically modified wood, preservative treated wood and wood composites. Even treated products may be subject to durability classification, but necessary...

Structural health assessment of wood - A comparison of methods for determining the spatial spread of fungal infestation in beams and rafters
2025 - IRG/WP 25-11051
Wood decay in buildings can cause severe economic losses, require comprehensive refurbishment, and removal of decayed wooden elements from the building. The latter aims at restoring the structural integrity of the component or the entire building through replacement, and at preventing the infestation from spreading further. In practice, components are cut out of the structure to such an extent tha...

Functionalization of wood with nano-sized titanium dioxide – Efficacy against mould growth and effect on cell wall integrity
2025 - IRG/WP 25-20740
Nano-sized titanium dioxide (nano TiO2) is a photocatalytic compound that generates reactive radicals under UV radiation, which can inhibit microbial growth and impart self-cleaning properties. This effect has been widely utilised on materials such as glass or tiles. This study investigates the potential of nano TiO2 treatments to prevent mould growth on wood and their impact on cell wall integrit...
