A fundamental research on the characteristics of a wooden house using urethane insulation panel attached to the outside of the wooden construction

摘要

This paper mainly deals with the promotion of the construction efficiency using urethane panels attached to the outside of the wooden flames. The size of standard panels was 900mm in width, 2,800mm in height, 100mm in thickness, and both sides of those panels were covered with a vinyl chloride steel plate. On fixing those panels, some problems remains to be solved because they were slippery but the fixation using screws went smoothly. The gaps developed between panels were measured after one year. And the results showed that the range of fluctuation was up to about 0.3mm, so it is unlikely to lose the air-tightness of the house. Therefore there is great possibility of their practical use.
