Expert Verdict Reviewed by the SuperArbor Pro Desk

Use SOPRALENE 180 SP 3.5 as the base ply of a two-ply system, torching over primered or approved substrates and keeping laps tight per the assembly detail. Confirm the full approved system components with the roof assembly spec, since approvals apply to installed systems rather than a lone ply. Carry full rolls and store them upright on end on a flat surface until installation.

Heat welding modified bitumen involves open flame; use trained installers, fire watch procedures and comply with local fire codes.
