Expert Verdict — Reviewed by the SuperArbor Pro Desk
Flat ISO is the workhorse polyiso board for commercial low-slope re-roofs and new construction. Match thickness to the R-value target per layer, and consider the 25 psi variants where higher load resistance is specified. Long 4 ft x 12 ft boards speed coverage on large open decks, while 4 ft x 4 ft pieces are easier to handle around penetrations; always follow the membrane manufacturer's attachment pattern.
Polyiso boards are lightweight but large panels are awkward in wind—stack and secure them on the deck and use fall protection per OSHA roofing requirements.
Order Versico Flat ISO insulation board in the thickness and panel size your roof assembly calls for.
