Securing Flame Retardancy in Wood: Durability After Artificial and Natural Weathering Test
2025 - IRG/WP 25-20738
The outdoor use of wood is often limited by challenges such as dimensional instability, vulnerability to fungal decay, and high flammability. Traditional flame retardant treatments improve fire resistance but suffer from significant leaching under environmental exposure, reducing their long-term effectiveness. This study introduces an innovative solution by integrating flame retardants with DMDHEU...

Curing Behaviour of Bio-based Phenol Formaldehyde Resin and the Durability Performance of Treated Wood
2025 - IRG/WP 25-20758
The aim of the study is to investigate the curing behaviours of bio-based PF resins treated Japanese Cedar (Cryptomeria japonica). Compared to conventional wood preservatives such as metal-based ACQ, bio-based PF resin was more environmentally-friendly and can store more plant-based carbon inside treated wood. However, all these preservatives have the risk of being leached out. This study conducte...

Enhancing Wood Greying: A Study of Pre-Treatments and Iron(II) Sulphate Application
2025 - IRG/WP 25-41018
Recent trends in architecture and environmental policies have increased the demand for natural, unprotected wood in outdoor applications. However, wood exposed to the elements tends to grey unevenly, which can be problematic for visually important applications like timber façades. One solution is artificial greying with iron ions, providing a uniform colour that later transitions to natural greyi...
