Abstract
The purpose of this research was to evaluate the vapor permeability of nine different species of domestic softwood and the vapor permeability evaluation through the production of small wall structures for the developing applications, utilizing the vapor permeability of wood. In addition, the permeability evaluation was attempted by means of the production of a small wall structure injected with a waste material, bottom ash, as a moisture absorbent for improving the permeability. Consequently, the results of the vapor permeability evaluation by means of Sd value are as follows: (1) It was observed that Abies holiphylla, Picea jezoensis, Ginkgo biloba, Pinus koraiensis and Pinus rigida are permeable to moisture among 9 species of domestic softwood in Korea. (2) By means of this, semi-permeability efficiency was evaluated when producing a small wall structure. (3) Besides, improved effects of permeability were evaluated when producing a small wall structure inserted with bottom ash. As a result, it was confirmed that the Sd value of Pinus koraiensis turned out to be 1.63, which is superior to other 8 tree species.
