Abstract
IRC recently completed its cross-Canada Building Science Insight Seminar Series (BSI) 2003 onmoisture management in small buildings. Several private-sector building envelope specialistspresented case studies concerning failures they had encountered related to poor control of rainpenetration and condensation. Out of the 15 case studies presented in the seminar series, arecurring problem appeared to be the balcony/exterior wall junction. Poorly designed or builtjunctions provided a path for rainwater infiltration into the wall, and contributed to the prematuredeterioration of wood-based elements of the wall. For several years, 'leaky condos' on the WestCoast made the news, and one could be led to believe that rain penetration failures are specific towet climates. These case studies indicate, however, that such problems can also develop in drierregions, such as Ottawa.
