EXTERIOR WALL STRUCTURE FOR PREVENTING SUMMER-TYPE DEW CONDENSATION

摘要

PROBLEM TO BE SOLVED: To help in effectively preventing summer-type dew condensation in a hot and humid area, etc.;SOLUTION: An exterior wall structure 1 for preventing summer-type dew condensation includes an exterior member 2, a heat insulating member 4 disposed in a space to the exterior member 2 via a ventilation layer 3 in which air flows, an interior member 5 disposed on an indoor side Hi of the heat insulating member 4, and an interior finishing member 6 stuck onto the indoor side Hi of the interior member 5. A moisture-proof layer 13 is disposed on an outer face 4o of the heat insulating member 4 facing the ventilation layer 3. The ratio (A/B) of a moisture transmission resistance A (m² h mmHg/g) of the moisture-proof layer 13 to a moisture transmission resistance B (m² h mmHg/g) of the interior member 5 including the interior finishing member 6 is 2 or greater.;COPYRIGHT: (C)2013,JPO&INPIT
