AbstractResearch was conducted on mechanically-attached roofing, low-slope assemblies to study the effect of air intrusion on performance. The research generated wind uplift data two for different roofing configurations: 1) assemblies without air retarders and 2) assemblies with air retarders. Typical mechanically- attached assemblies with and without air retarders were evaluated for wind uplift performance. The research clarified how air intrusion in mechanically- attached, low-sloped membrane roofs differs from air leakage through wall and window assemblies.
