Abstract

Lightweight wooden structures are continuously being distributed in Korea. According to the recently strengthened insulation standards, the cases of adding external insulation to the 2X6 lightweight wooden structure are increasing, and it was investigated that EPS insulation and glass wool insulation are being used. EPS has a water vapour diffusion resistance coefficient of 50, and glass wool has a coefficient of 1, indicating a large performance difference. Therefore, in this study, the change in moisture load of the lightweight wooden structure wall was analyzed according to the difference in exterior insulation material and the regional climatic conditions.
