SpecSeal SSW BLU/BLU2 Intumescent Wrap Strip

SpecSeal® BLU/BLU2 Wrap Strips are versatile, high‑performance intumescent firestop wraps available in multiple sizes and configurations to address virtually any combustible pipe penetration.

When installed together with restraining steel, SpecSeal BLU/BLU2 Wrap Strips deliver exceptional expansion and fire‑resistance capability—capable of crushing and sealing non‑metallic piping up to 12 inches in diameter. This makes them a reliable, code‑compliant solution for protecting large‑format combustible penetrations in fire‑rated floors, walls, and floor/ceiling assemblies.
