What is firestop?

firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fireproofing of a wall or floor assembly allowing it to impede the spread of fire and smoke.

Firestops prevent unprotected horizontal and vertical penetrations in a fire-resistance-rated wall or floor assembly from creating a route by which fire and smoke can spread that would otherwise have been fire resisting construction, e.g. where a pipe passes through a firewall.

Fire stopping is also to seal around gaps between fire resisting constructions, e.g. the linear gap between a wall and the floor above, in order for construction to form a complete barrier to fire and smoke spread.

Opening types
Firestops are used in:

  • Electrical, mechanical, and structural penetrations
  • Unpenetrated openings (such as openings for future use)
  • Re-entries of existing firestops
  • Control or sway jointsin fire-resistance-rated wall or floor assemblies
  • Junctions between fire-resistance-rated wall or floor assemblies
  • Head-of-wall (HOW) joints, where non-load-bearing wall assemblies meet floor assemblies

Materials

Components include intumescentscementitious mortarssiliconefirestop pillowsmineral fibers, and rubber compounds.

Tagging

Proper maintenance is enhanced by the installation of tags on each side of the firestop with information needed to refer to documents indicating approved procedures for the original installation and re-entries. This requires knowledge of the certification listing used for each opening of a building joint or a penetrant through-penetration seal.

Ratings

Firestop materials are not rated per se. They receive a fire rating by combining materials in an arrangement specific to the item (a pipe or cable, for example) penetrating the fire-rated wall or floor and the construction arrangement of the fire-rated wall or floor. A two-hour-rated pipe-penetration firestop may consist of a layer of caulking over packed rockwool. The arrangement, not the caulking, provides the two-hour rating. The individual firestop materials and the overall firestop assembly are listed.
