ABSTRACT:Laboratory water spray testing identifies the performance of a component or assembly under a specified set of simulated wind-driven rain conditions. Well-developed water spray test protocols can also help identify were an assembly is vulnerable to water entry, the test loads at which water entry occurs, and whether the water entry is managed by the installation details in such a way that it does not result in within-wall damage. This paper presents a proposed laboratory test protocol for assessing the effectiveness of wall-window interface details with regard to management of rainwater, and provides a rationale for a performance-based approach to the evaluation method. An overview of the test approach is provided and details of the test apparatus and test specimen are given, including information on implementation of the test method. Examples of testing performed according to the proposed protocol are provided. Finally additional tests for evaluating the performance of installation details are suggested. The additional tests are for field evaluation of installation details, and for laboratory evaluation of installation details with regard to the risk of condensation along window frames.KEYWORDS: installation details, laboratory testing, performance test, rainwater int...

ABSTRACT:The detailing of wall-window interfaces and the consequences of defective installation of windows is an on-going concern in North America. This manuscript concerns laboratory evaluation of the water leakage performance of a select set of window-wall interface details. The details were for windows with mounting flanges installed in wood-frame walls sheathed with rigid extruded polystyrene foam. The tests were performed on a single full scale test assembly in which two identical windows were installed by two similar but nonetheless different means. Each detail included a sill pan intended to collect water that gained entry into the assembly and thus was designed to be robust (tolerant of flaws). Tests were performed over a series of different water loading (spray) rates, and over a series of different air pressure differentials at each spray rate. Air leakage rates through the window opening were monitored; they were controlled by a unique methodology. Leakage paths were introduced in the window frames and these paths were alternatively blocked or opened to permit evaluation of the performance of the installation details under two different assumed conditions of window leakage. Air pressure distribution within the assemblies was monitored during spray testing. The wall assembly were designed to permit observation of water entry in it, and to allow ...

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 such systems. This paper reports on results obtained from laboratory testing of two sets of wall-window interface details and variations on their implementation, that are representative of residential and light commercial window installation practice in the US. Results from these tests indicate that the window installations details of the type assessed in this study are adequate to manage even the most significant rainfall events as might occur in North America. It was also demonstrated that window installation designs that do not permit drainage from the sill are vulnerable to excessive water retention during signif...

Forty-six buildings are studied. Thirty-seven buildings had experienced problems, and nine did not (&dquo;controls&dquo;). These are low-rise wood-frame residential buildings; most are three and four storeys high. Buildings are located in the coastal climate ofBC Lower Mainland. Buildings are eight years old or less. Problem buildings were defined as those where a moisture problem within the walls, decks, or exterior framing resulted in damage requiring $10,000 or more of repair. Control buildings are those buildings which did not experience such moisture problems over the last five years. WALL ASSEMBLIESCladding materials were restricted to stucco, vinyl siding, and wood siding. Framing was wood in 38 by 89 mm or 38 by 140 mm Asphalt-impregnated building paper and housewrap (either spun-bonded polyolefin sheet or perforated polyethylene sheet) were represented. Plywood and OSB sheathing were represented. Windows are mostly aluminum frames without a thermal break. These windows typically have a drained frame design; the frame joints are often reported to be unsealed, as are the joints between the frame and the clad-
