| Outline of Final Research Achievements |
One of the most significant deterioration of historic wooden buildings is that caused by wood boring insects. Conventionally the wooden buildings damaged heavily by insects have been treated by fumigants such as sulfuryl fluoride. In this project, we did researches in order to apply humidified heated air to eradicate wood boring insects in historic wooden buildings with traditional painted layers of urushi or with polychrome sculptures. Firstly with basic research, the system to precisely control the ambient temperature and humidity of the space was built to control core temperature and humidity of timbers. And with test pieces with polychrome painted layers and with various sizes of wooden blocks, data of contractions, colors and cracks were closely investigated. Then we applied the system to a middle scale test building with cost effective insulation covering. Finally with the constructed system, a historic building in Nikko was treated without any visible adverse effects.
