Abstract
The purpose of this study was finding out proper wall assembly to reduce moisture accumulation in light frame wall under outdoor air conditions. For the purpose, moisture transfer and accumulation in a wall were evaluated for five types of wall assembly; typical wall (T), addition of a vapor retarder (P1), addition of two vapor retarders (P2), addition of an open air gap for ventilation behind the siding (P3), and shift of vapor retarder with proposed wall 'P3' (P4). The moisture transfer and accumulation in the all walls were evaluated after applying the typical and proposed walls to the field test house. Performances of the typical and proposed walls were compared according to the season. Rank for effective wall on reducing moisture accumulation in wall was 1) shift of vapor ratarder and addition of open air gap (P4), 2) addition of vapor retarder (P1), 3) typical wall (T), 4) addition of open air gap (P3), and 5) the other (P2).
