Expert Verdict Reviewed by the SuperArbor Pro Desk

This TG-grade cap sheet is a good match when a fire-rated assembly needs a mineral-surfaced finish with SBS flexibility for cold-weather performance. Torch application gives the fastest installation on open field areas, while cold adhesive with heat-welded seams suits occupied buildings where open flame is restricted. Always confirm the full assembly, including base sheets and insulation, with the manufacturer before committing to a system.

Torch application involves open flame and fire risk; follow hot-work safety practice, keep extinguishers on hand, and verify combustible deck conditions before torching.
