SpecSeal® RED/RED2 Wrap Strips are high‑performance intumescent firestop wraps available in a wide range of sizes and configurations to address virtually any combustible pipe penetration. Offered in convenient 12‑ft rolls as well as individually pre‑sized strips, RED/RED2 Wrap Strips help reduce material waste and streamline installation on both new construction and retrofit projects. When paired with restraining steel, SpecSeal RED/RED2 Wrap Strips deliver powerful intumescent expansion—capable of collapsing and sealing non‑metallic piping up to 12 inches in diameter during fire exposure. This makes them an ideal, code‑compliant solution for achieving reliable fire resistance across fire‑rated floors, walls, and floor/ceiling assemblies.
