Expert Verdict — Reviewed by the SuperArbor Pro Desk
Pano Ply 4 Type IV fiberglass ply is chosen for durability and dimensional stability in multi-ply BUR assemblies. Confirm the number of plies and bitumen type from the roof system specification, since Class A and FM ratings apply to the full assembly, not the sheet alone. Maintain specified laps and bitumen temperatures during mopping.
Built-up roofing involves hot bitumen and work at height; use fall protection, heat-resistant PPE, and follow safe kettle and mop procedures.
