Air leakage characteristics of some brick and concrete block walls.

Presents the air leakage characteristics obtained from measurements of nine brick and concrete block walls in the DBR/NRC huts at Ottawa and Saskatoon. The leakage characteristics of the first three walls were obtained in the Saskatoon test huts - the remainder were obtained in the Ottawa huts. All thetest huts had an overall plan area of approximately 6 ft. by 6 ft. The effects of fill-insulation and different surface finishes were determined.
