Are Firestop Collars Required by Building Code?
Yes—firestop collars are required by most local and international building codes when non-metallic pipes penetrate fire-rated walls or floors. These collars contain expanding intumescent materials that activate in high temperatures to seal off pipe openings. When fire hits, the collar expands, crushes the softened pipe, and restores the wall’s or floor’s integrity—buying critical time during emergencies. Firestop collars are commonly used in hospitals, schools, commercial buildings, and multi-family homes. Ensuring these are installed correctly is not only a legal requirement but a life-saving safety measure in fire protection planning.
