Air leakage through various forms of building construction

Reports tests made to determine the air leakage characteristics of various types of walls. Describes apparatus and method and gives results of tests on brick, wood frame, stucco and brick and tile walls, with and without plaster, paint and caulking. Finds that air leakage characteristics alter with the age of the wall, that paint alone did not greatly reduce the leakage of the brick wall, but that plaster was very effective. Also gives data for leakage between plaster or stucco and wood frame.
