firestops
Fire spread preventers
Firestops are barriers installed in buildings to prevent fire and smoke from spreading through openings in walls, floors, and ceilings.
They seal gaps around pipes, cables, ducts, and joints where flames could otherwise travel between compartments.
Building codes typically require firestops in commercial and residential construction: The inspector checked that all the firestops were properly installed around the electrical penetrations.
