| Abstract | The condensation of moisture on or within walls and attic spaces of houses is an old and troublesome problem. Depending upon a combination of conditions, ice or frost may form and its subsequent melting may cause stains on wall and roofing members, interior discoloration, and exterior paint failure on siding and finishing. Reports of these damaging effects, and tenant complaints of interior leakage on to walls, curtains and furniture in wartime rental houses owed by the Central Mortgage and Housing Corporation, resulted in a request from the Corporation for the assistance of the National Research Council in the examination of a large number of their rental houses in the Winnipeg area. |
