| Abstract | Inadequate detailing practice and defective installation of windows has accounted for a significant number of premature failures of the building envelope. This has spurred the development of alternative construction details to manage water intrusion at the wall-window interface. Laboratory investigations focused on assessing the effectiveness of wall-window interface details to manage rainwater intrusion in the wall assembly have provided an effective way to obtain useful information on the varying performance of different interface details. Previous studies undertaken to investigate the effectiveness of details typically used in wood frame low-rise wall assemblies have shown the degree to which different details manage rainwater intrusion and the extent of fault tolerance of these systems. This paper offers a report on more selected results obtained from evaluating the watertightness of a series of four wall-window interface details representative of construction practice across Canada. A brief overview of four sets of wallwindow interface details and variations on their implementation are described in general and details for a set, comprised of two specific wall-window interface details evaluated in the study are provided. The set of two variations of interface details described were configured for a fixed PVC window incorporating mounting flanges and installed in a rainscreen wall. The results of water penetration tests are provided in terms of water entry through deficiencies in the cladding, water collection within the assembly and the severity of the simulated wind-driven rain loads. The effectiveness of the two approaches to window installation in managing rainwater entry is discussed. |
