Expert Verdict — Reviewed by the SuperArbor Pro Desk
Polyiso is the standard continuous insulation choice in low-slope roof assemblies; taper thermal design per R-value requirements with the board thickness you specify. Store boards off the ground and covered until install, and butt boards tightly with joints staggered between layers when multiple lifts are used. Confirm board dimensions and R-value from the manufacturer's data sheet, which the listing does not include.
Handle foam boards carefully and follow job-site fire-safety requirements for exposed insulation during construction.
