Sterilization of Large Timbers during Preservative Treatment: How Quickly We Forget
2020 - IRG/WP 20-40902
Air seasoning is a common method of moisture management in utility poles and is done de facto during pole storage prior to treatment. However, extended air drying prior to treatment encourages fungal attack and can facilitate establishment of decay fungi in poles before a protective preservative barrier is applied. This problem can be mitigated by proper air-seasoning methods coupled with heat ste...

Utilization of Pressure Treated Lumber in Cross Laminated Timber Manufacture and its Impact on Bondline
2022 - IRG/WP 22-40953
Mass timber building construction is increasing dramatically across North America which presents challenges to these structures not seen in Northern Europe. Large parts of the United States harbor termites and existing mass timber building technologies that rely solely on moisture exclusion to increase durability are insufficient in these areas. The successful expansion of mass timber construction...

Durability of thermally modified western hemlock lumber against wood decay fungi
2022 - IRG/WP 22-40954
The chemical modification of wood is gaining popularity as a treatment to increase wood durability in the United States. Further standardization and testing of thermally modified North American species is needed to optimize the production of thermally modified products from regionally available resources. This work measures the impact of thermal modification of western hemlock lumber durability ag...

Comparison of culturable fungi found on two types of modified wood cladding
2023 - IRG/WP 23-11025
Modified woods are rapidly gaining popularity in the United States and are appearing on more public buildings. Because these are biocide-free products, they can support the growth of non-wood degrading fungi on their surfaces, many of which produce dark pigments and deface the cladding. Even growth of dark pigmented fungi on modified woods yields an even grey-black color, giving the materials a we...
