Condensation in Insulated Masonry Walls in Summer
Masonry walls for residential construction in Canada require some form of insulation for wintertime comfort and fuel economy. In order to achieve a thermal standard equivalent to that normally provided by insulated wood-frame construction, approximately 2 in. (5 cm) of insulation is needed. One method is to apply blanket or batt insulation on the inside of the masonry, between wood furring strips that support the inside finish. It is normal practice to provide a vapour barrier membrane on the inside of the insulation to control condensation due to outward moisture movement in winter. An additional consideration is the moisture separation required, if any, between the masonry and the inner components of the wall. To study this question for conditions in central Canada, some insulated masonry test huts were constructed in Ottawa; these were heated and humidified in winter and observations were made of moisture conditions throughout the year. No moisture problems were encountered in winter but some undesirable wetting conditions developed during the summer period. The paper describes the construction arrangements and the moisture observations. (Author)
