Transfer of microorganisms from wooden crates to foodstuffs: assessment of a transfer threshold
2016 - IRG/WP 16-20574
Wood is commonly used in contact with foodstuffs, for example for packaging fruits or vegetables. Most common species used are beech, pine, spruce and poplar. Wood is often considered as being less safe than plastic because it is less easy to clean whereas several studies have demonstrated that microorganisms cannot survive easily on wood (Milling et al., 2005; Revol-Junelles et al., 2005). Nation...

Assessment of the biological durability of wood treated with organosilicon compounds
2016 - IRG/WP 16-30685
The European wood construction market is in need of environmentally friendly wood-based products whose service life meets the expectations of end users. Non-biocidal silicon-based water repellents, which can be applied to different materials, help minimize their vulnerability/susceptibility to liquid water. Consequently, they have the potential of increasing wood’s resistance against decay fungi...

Fungal growth on coated wood exposed outdoors: influence of coating pigmentation, cardinal direction and inclination of wood surfaces
2017 - IRG/WP 17-10896
The objective of the SERVOWOOD project was to develop and establish European Standards that will facilitate the prediction of service life for exterior wood coatings. One of the objective of this project was to study fungal growth of the field exposed panels. Two coatings applied in 2 and 3 coats were exposed for one year outdoors at 45° south: one solventborne (alkyd based) and one waterborne (a...

Novel wood treatments improve resistance to the wood-boring marine isopod Limnoria quadripunctata
2017 - IRG/WP 17-10899
The marine isopod Limnoria quadripunctata degrades wooden structures in the sea and causes significant economic damage. Broad-spectrum biocides and naturally resistant tropical hardwoods have failed to prevent feeding by Limnoria and have caused ecological damage. Wood modification is now the favoured method, and resin-based modifications have been effective, while the efficacy of silica-based mod...

Organosilicon-based impregnation hydrophobers for wood
2017 - IRG/WP 17-40808
The SILEX project “Improving sustainability of construction materials using innovative Silicon based treatment” is a Life+ project with reference LIFE+11 ENV/BE/1046 and started in April 2013. This project intends to demonstrate that a new class of compounds can be used for wood treatment for an extended service life combined with enhanced new testing methodology. The project aims at demonstra...

The Impact of Cryopreservation Techniques and of Water Quality on the Wood Degrading Ability of Fungal Strains: Recommendations for Maintenance and Culturing Procedures
2018 - IRG/WP 18-20636
In order to establish an optimal cryopreservation method, strains of Basidiomycete and Ascomycete fungi, which are among the most frequently used for wood durability testing, were evaluated using three cryopreservation procedures at -80°C. The main objective was to prevent decrease of the fungal virulence that may occur due to repeated routine sub-culturing procedures and to optimize the reactiva...

Durability by design – a case study of the performance of wooden decks after 9.5 years of natural weathering
2019 - IRG/WP 19-20648
The service life expected for wood decking manufactured with poorly durable wood species, left untreated and exposed to severe environmental conditions such as high humidity and active biological agents, is usually assumed to be short (less than 10 years). The current classification of wood’s natural durability is based on EN standardised tests which do not fully reflect the real end-use conditi...

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 ...

Update on the Distribution of Termites and other Wood-boring Insects in Europe
2020 - IRG/WP 20-10960
In Europe, most of the timber used in construction is made from softwood species that are poorly or not durable against wood-boring organisms (beetles, termites, decay fungi). Timber with a moisture content of less than 20% can be attacked and degraded by different species of insect whose larvae consume wood and significantly reduce its mechanical strength. The risk of attack by wood-boring insect...

Assessing the Performance of Wood-based Materials Exposed to Termite Risk – A New Experimental Approach
2022 - IRG/WP 22-10989
Termites are able to degrade a large number of building materials including wood, wood-based panels, biobased insulation, and polymers. The risk for a material of being degraded by termites depends on its composition, on its accessibility, and also on the behavior and the biology of the termite species considered. Within the EU project Click Design, we investigated the durability, under laboratory...
