Expert Verdict — Reviewed by the SuperArbor Pro Desk
Choose this FR GR cap ply when a job calls for a granulated, fire-retardant wearing surface in a multi-ply SBS system; the polyester mat gives real puncture resistance around rooftop traffic. White reflects heat on occupied or low-slope buildings, while Black and Gray suit aesthetic-matched details. Overlap side laps properly and weld cleanly through the burn-off film for watertight seams.
Heat welding modified bitumen involves open flame and hot surfaces; use trained installers with proper fire-watch and safety equipment per the manufacturer's instructions.
