SECUROCK gypsum-fiber cover board is the standard choice between polyiso insulation and the single-ply membrane when you need wind uplift, hail, and foot-traffic protection without facer-delamination risk. Because the panel is homogeneous, adhered installs deliver an exceptional bond and low absorption; stagger joints and install per the membrane system specification to keep the FM or Miami-Dade approval valid.
