Preservation conditions of wooden roofs of two historical churches in middle-Sweden
2025 - IRG/WP 25-41016
Assessment of biodegradation by the rot of shingles from the roofs of churches of Hammarby and Tångeråsa in mid-Sweden was done by studies with X-ray computer tomography. The study suggests that inner rot could be detected with CT, which was not always easily detected by visual inspection. In some cases, erosion from the weathered side was fairly large, but the inner wood part was found not to b...

Investigation of Impregnation Factors for Biomass-Based Phenol-Formaldehyde Resins
2025 - IRG/WP 25-41044
This study investigates the impregnation factors affecting the treatment of wood with biomass-based phenol-formaldehyde (PF) resins, such as impregnation methods, resin properties, and setting parameters like time and pressure. The goal is to ensure effective resin penetration into the wood cell wall structure, thereby enhancing wood durability and mechanical properties. Previous literature has la...

Developing a Novel Bio-based PF Resin as Wood Preservative and Explore its Synthesis Route Using RSM Methodology
2025 - IRG/WP 25-41046
Phenol-formaldehyde (PF) resin treatment has long been recognized as one of the most effective and widely used wood preservation methods, offering exceptional durability, dimensional stability, and resistance against biological degradation. However, traditional PF synthesis relies heavily on petroleum-derived phenol, raising concerns about environmental impact and resource sustainability. To date,...

Investigation of Pressure-Treated Foundations with Wood Preservative and Termite Control in Existing Wooden Houses in Japan
2025 - IRG/WP 25-50402
Japan has extremely limited natural resources. Therefore, it is necessary to build a circular economy in which waste and other recyclable resources are effectively utilized in order to achieve sustainable development. This study aims to investigate the degradation of existing wooden houses and to contribute to the reuse of existing houses and the reuse of building materials during demolition. We i...

A Study on the Damage and Conservation of Wood in Dense Areas of Wooden Buildings
2025 - IRG/WP 25-50412
One of the key threats to timber buildings in large parts of the world is the risk for damage by termites. Therefore, effective preservation strategies need to be developed. The study presented here is focussing on the current condition of wooden houses in the Seocho area, a densely built wooden residential area in Jongno-gu in Seoul, Korea. This study has been conducted to explore the proactive a...

Analysis of A Wooden Structure Damaged in a Fire – The Wooden Granary at Zaprice, Kamnik
2025 - IRG/WP 25-41049
Zaprice Open-Air Museum in Kamnik, Slovenia, features several granaries dating to the early 19th century, forming part of the national Cultural Heritage Register (EID: 1-09881). One of the two-chamber wooden granaries, constructed in 1828, suffered significant fire damage in December 2024. The objective of this study was to evaluate the extent of the damage, assess the structural integrity, and id...
