Suberinic acid from birch bark and its suitability in wood protection
2024 - IRG/WP 24-20708
This study investigated the effect of different concentrations of suberinic acid (SA) on the growth of two fungi species. Initial radial growth tests showed a slightly slower growth rate for brown rot, whereas white rot exhibited faster growth than the untreated reference. In contrast, a commercial wood preservative significantly reduced the radial growth of both fungi species. Evidence of cell wa...

Studies on the treatability of selected pine species and corresponding efficacies of a new non-biocidal treatment
2024 - IRG/WP 24-20721
Wood decay caused by fungi may reduce the service life of wood in outdoor applications. Since moisture conditions in wood occur as one of the most crucial parameters for fungal decay, chemical modifications, which affect the latter, may increase the resistance of wood against such organisms. Usually, pine sapwood is easier to chemically treat than heartwood, as the former generally shows good perm...

The potential of Wacapou (Vouacapoua americana) extracts to develop new biobased protective solutions for white woods
2024 - IRG/WP 24-20724
The valorisation of Amazonian wood residues into active chemical compounds could be an eco-friendly, cost effective and valuable way to develop wood preservatives formulations in order to enhance the decay and termite resistances of low durable wood species, by impregnation processes. Wacapou (Vouacapoua spp., Fabaceae) is a well-known Guianese wood species for its use in local wood construction ...

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...
