FIRE STOPPING




A firestop is a fire protection system made of various components used to seal openings and joints in fire-resistance rated wall and/or floor assemblies.

Firestops are designed to restore the fire-resistance ratings of wall and/or floor assemblies by impeding the spread of fire by filling the openings with fire-resistant materials. Unprotected openings in fire separations cancel out the fire-resistance ratings of the fire separations, allowing the spread of fire, usually past the limits of the fire safety plan of a building.

The materials used in firestops do not have ratings on their own. Firestops achieve a fire rating by combining certain materials in an arrangement specific to the item penetrating the fire rated wall or floor, and the construction arrangement of the fire rated wall or floor itself. For instance, penetration firestop may consist of a layer of caulking over packed rockwool. This overall arrangement provides the two-hour rating, not the caulking. However, both the individual firestop materials and the overall firestop assembly are 'listed' per listings and approval use and compliance.
