The external thermal insulation system for wooden houses is one of the popular thermal insulation systems in Hokkaido, Japan. We propose a bearing wall system for wooden frame houses to improve seismic and thermal insulation performance at the same work. The fastener to fix the external thermal insulation system is utilized also to fix structural board more tightly. And the foamed plastic board in the external thermal insulation system to improve thermal performance also improve seismic performance to keep clearance none between structural board and wooden frame. The system provides as almost three times of toughness as normal.
