firestopping
Blocking fire spread
Firestopping is the use of fire-resistant materials to seal gaps and openings in walls, floors, and ceilings where pipes, cables, or ducts pass through.
The goal is to prevent fire and smoke from spreading between compartments of a building: The inspector noted inadequate firestopping around the electrical conduits.
Building codes typically require firestopping in commercial and multi-unit residential construction.
