Abstract
Recently, It would be necessary that the relationship between the presavation of forest environment and the utilization of waste wooden materials is balanced to conserve the build environment toward the near future. From the standpoint of these backgrounds, some kinds of Wood-based Inorganic External Panels were started to develop these days. In this study, The Wood-based Inorganic External Panels were producing, and the usability, environmentality(thermal insulation, thermal conduction) and fundamental properties of them were evaluated in the experiment. In additions, the calculation of total amount of CO2 emmissions and embodys in the case of applying the external wall panel on single residence were conducted.
