Influence of the substitution of phenol with lignin cleavage products in phenol-formaldehyde impregnation resins for wood modification on the fungal decay resistance and impregnation depth
2024 - IRG/WP 24-30805
The impregnation modification of wood with phenol-formaldehyde (PF) resins increases the woods dimensional stability and resistance against fungal decay. However, to decrease the usage of non-renewable resources, the substitution of phenol has been a topic of scientific interest. Lignin is a currently underutilized resource with a chemical structure that contains phenolic units. For adhesive appli...

Bio-durability and weathering performances of cardanol-treated wood
2024 - IRG/WP 24-30809
Cardanol is an excellent insecticide, fungicide, and termiticide derived from thermally treated cashew nutshell liquid (CNSL) and has been extensively explored in the chemical industry and for medicinal uses. However, its potential for wood protection remains unexplored. This study aims to understand the bio-durability and weathering properties of cardanol-treated wood. The southern pine and yello...

How personality traits influence the perception of fungal decay in a wooden cladding – A survey in three Modelling wood moisture content in outdoor conditions from measured data
2024 - IRG/WP 24-41002
This study examined perceptions of fungal decay damage on wooden cladding across Norway, Sweden, and Germany. The majority of respondents across all countries did not find the fungal decay damage in question acceptable, with the least acceptance in Norway. This could be due to Norway having the highest frequency of wooden residential buildings and the most experience with maintaining wooden claddi...
