Firestops
A firestop is used to seal openings in fire-resistant wall and/or floor assemblies. The material
between cabling systems is intended to prevent the passage of flames from one cable system
to an adjacent cabling system. Unprotected openings void the fire-resistance ratings and
affect the fire safety plan of the entire building.
Floor

multiple, stories.
