Abstract
The commercial buildings encompasses hospitals, schools, offices, lodging, and the retail sector with its big box stores, enclosed malls, strip malls, grocery stores and fast food restaurants Approximately one fourth of North American commercial buildings are roofed with Flexible Roof Systems (FRS) (NRCA 2004). In FRS, the waterproofing membrane is on the top exposed to the environmental forces with other roofing components such as insulation and cover board below it integrated to the structural substrate using mechanical fasteners. Field observations have identified that air intrusion in mechanically attached roof systems can affect roof system performance. However, the question of how much air movement occurs and which components provide the required resistance to air movement has never been addressed. To measure air intrusion in mechanically attached roof systems, an experimental study is recently completed at the National Research Council (NRC) of Canada as part of its Special Interest Group for Dynamic Evaluation of Roofing Systems (SIGDERS) research.
