Through-Penetration Firestops that Expand to Seal Out Fire, Smoke and Toxic Gasses

FlameSafe® Bags are a unique firestop product allowing easy access to cables, cable trays, and metallic pipes for through-penetrations in fire-rated floors and walls. FlameSafe® Bags are patented bags consisting of tightly woven, durable, coated cloth, filled with a combination of mineral fibers, incombustible components, intumescent agents and special fire-retardant additives. They are resistive to the environment and retain their properties and effectiveness when subjected to weather, temperature and atmospheric conditions.
