Authors have so far experimented to indoor air flowing in into a wall. As a result, it has reported that indoor air flows in into a wall even from openings with a slight wall socket. In this report, filling-up thermal insulation wall model using inorganic fiber insulating materials packed in polyethylene bag which has spread most in the warm area was used. The wall socket assumed to be openings was installed on the interior wall, and the experiment was conducted using house wrapping sheet and plywood for structures as wall composition material. As a result, the dew condensation situation in a wall was confirmed. In addition, by making a hole in plywood for structures, vapor resistance of a wall was reduced and the method of construction which decreases the quantity of dew condensation in a wall was examined. Furthermore, even if indoor wet air flows in into a wall, a measure method of construction with the effect which controls generating of dew condensation is proposed. Morevoer, comparison examination of the conventional method of construction and the new measure method of construction is carried out.
