Preventivephysical barriers against subterranean termites species for building protection: How to implement innovative materials to reach efficacy requirements
2018 - IRG/WP 18-40845
As the European regulation dealing with the use of biocides (BPR) for preventive protection of buildings against subterranean termites is leading to more and more pressure on physico-chemical barriers currently used (PT18), some existing developments are focusing attention on physical biocides-free barriers. The main target is then to avoid the use of active ingredients, to stay out of the BPR sco...

Promoting Commercially Available Epoxy Resins for Non-biocidal Wood Preservation
2019 - IRG/WP 19-40877
Commercially available epoxy and polyamine resins were evaluated with the aim of developing new non-biocidal wood preservation treatments. A simple method allowing the impregnation of wood by vacuum double impregnation followed by a curing process was developed for two reference species, beech Fagus sylvatica and Scots pine Pinus sylvestris. The tested products were evaluated for their ability to ...

Monitoring of wood preservatives exposed to weathering: Extraction and analysis methods of organic biocides from treated wood and collected rain runoff
2020 - IRG/WP 20-30753
Weathering is the cause of numerous damages for outdoor joineries. Protection of wood using a preservative treatment covered with a coating is a process widely used to limit these damages. However, biocides from preservative treated wood are prone to degradation and leaching, having a direct influence on the joinery service life. This document deals with extraction and analytical methods for bioci...

Effect of MVOC exposure on mycelial growth of wood rotting fungi
2021 - IRG/WP 21-10977
It is well known that wood rotting fungi produce microbial volatile organic compounds (MVOCs) as metabolites. In our previous studies, we have found that some MVOCs produced by wood rotting fungi are common to fungal species tested in the studies, while others are specific to each species. Furthermore, it has been also shown that each wood rotting fungi do not always produce the same type of MVOCs...

Effect of volatile organic compounds produced by wood rotting fungi on mycelial growth
2023 - IRG/WP 23-11023
Microorganisms such as fungi or bacteria produce volatile organic compounds (so-called MVOCs: Microbial Volatile Organic Compounds) as metabolites. Some MVOCs have been found to be biologically active, for example inhibition of spore germination, and when fungi of different species encounter each other, the MVOCs pattern change, suggesting that MVOCs play a role as a mediator for biological intera...

Environmental Benefits of Wood Preservation
2023 - IRG/WP 23-50377
Over the past decade or two, many people have become significantly more aware and concerned about the global environment and the health of our planet. Building with wood products from sustainably managed forests carries significant environmental benefits. The ability of a growing tree to absorb carbon dioxide (CO2) and sequester the carbon is beneficial in the role of combating rising CO2 levels...

Developing thermal-energy storage systems based on Kraft lignin-glyoxal and organic phase-change material modified wood
2024 - IRG/WP 24-30810
This study investigated the use of modified wood as a thermal-energy storage material through the integration of paraffin-based phase-change materials (PCMs). The objective was to evaluate the influence of Kraft lignin-glyoxal prepolymer on the properties of wood modified with PCMs. The implementation of the modified wood involved preparing PCM emulsions, synthesizing lignin-glyoxal prepolymer, an...
