Dew condensation phenomenon is menacing to the exterior wall with thermal insulation. This phenomenon occurs on the inside surface of the house wrapping sheet by air infiltration that passes from indoor to outdoor through gaps of defective parts. The present survey for engineering companies, mainly construction companies, on the use of thermal insulation in the IV climatic province was conducted in 2003. And it is confirmed that fiber fill thermal insulation walls were widely used in IV climatic province. An experiment was carried out in an artificial meteorological room in order to clarify dew condensation phenomena. In the experiment, we used fiber fill thermal insulation walls with minute openings, which simulated gaps on the wall. The results of the experiment revealed that moist air in the room invaded from the inside panel to the outside panel of the wall when there were gaps on the inside panel.
