Abstract
A type of built-up roofs known as adhesive-applied roofing systems (AARS) uses no fasteners for component attachment. All of the AARS components (e.g., insulation board, cover board, and membranes) are integrated through the application of adhesives. Since there are no metal fasteners through which moisture migration and thermal bridging might normally travel, AARS eliminates these. Moisture in the roof envelope can generally lead to material deterioration, structural integrity problems, and the growth of mold. Even though AARS are being used, there is no dynamic test standard available to quantify their wind-uplift performance. Recently, the National Research Council of Canada (NRC) completed a five-year project, “Development of Wind Uplift Standard for Adhesive-Applied Low-slope Roofing Systems,” in collaboration with industries, universities, and the government. Experimental data show that among the mock-ups, the weakest link varied depending on the type of adhesives used and component arrangements. This paper presents and discusses that data from this experimental investigation and development of a new wind uplift standard for the AARS.
