Expert Verdict — Reviewed by the SuperArbor Pro Desk
Use SBS Smooth where the specification calls for a flexible, glass-enhanced interply that tolerates thermal movement; the cold adhesive option is helpful where kettles or torches are impractical. On roofs with many penetrations, interply plies like this conform well around details. Always confirm the approved adhesive or asphalt and lap requirements from the Elevate system spec.
Follow safe handling practices for hot asphalt or solvent-based cold adhesives, including ventilation, PPE, and fire precautions during application.
