Expert Verdict — Reviewed by the SuperArbor Pro Desk
Sopralene 180 SP 3.0 serves as the base layer in torch- or heat-welded two-ply SBS assemblies, and its burn-off underside film is what lets heat welding bond cleanly. Follow the approved Soprema assembly specification for cap ply pairing, substrate priming and flame application, and check the project's FM approval requirements against the listed assembly. Store rolls upright on end and off the ground before installation.
Torch-applied modified bitumen requires trained installers, fire watch and fire extinguisher on site during hot-work application.
