Expert Verdict — Reviewed by the SuperArbor Pro Desk
C panels carry the same 0.50 in. taper per 4 ft. as other profiles but start 2 in. thick, so they typically fill rows adjacent to the slope's high point. Confirm the total system build-up so the thick edge does not create a step at equipment curbs or parapets. Blend with base and filler flats per the taper plan.
Stack and secure panels flat; uneven foam edges are a trip hazard on busy roofs.
Order the TRI-BUILT C-profile 2.00-2.50 in. tapered polyiso panel for your tapered roof layout.
