Expert Verdict — Reviewed by the SuperArbor Pro Desk
SECUROCK UltraLight is a go-to cover board for adding hail/foot-traffic protection and fire performance over polyiso. Stagger end joints and keep edges loosely abutted, and note the 5 in. flute span over metal deck for 1/2 in. board. Order board only for the area you can membrane the same day to limit moisture exposure.
Wear gloves and eye protection when cutting and handling gypsum board; install only per Carlisle specifications and local code.
