Adding insulation to the interior side of masonry walls in cold climates may cause performance and durability problems. Four such concerns were studied in more detail in this work. Embedded wood joist ends were monitored for moisture content and relative humidity, in a solid brick building that is being retrofitted with interior insulation. The effect of dissolved salts on masonry durability was examined, including their effect on freeze-thaw behavior, subfluorescence effects, and the effect on material property testing. The methodology of the frost dilatometry testing was optimized. Changes included sample size reduction, length measurement protocols, and optimization of the freeze-thaw cycle time. These changes improve throughput without loss of test accuracy.
