The improvement of heat insulating performance is one of the major problems of traditional wooden houses in Japan. In this paper, the effect of chaff filled wood panel which was newly developed for house wall is discussed by comparing with some another materials. By the artificial weather control eguipment, the coefficient of overall heat transmission and thermal conductivity were measured. The performance of chaff filled panel is as high as the glass wool of thickness of 6 centimeters.
