What is the primary purpose of firestop systems?

The primary purpose of firestop systems is to prevent the spread of fire and smoke throughout a building. Firestop systems are critical for maintaining the integrity of a building's fire-resistance-rated assemblies, which include walls, floors, and ceilings. When a fire occurs, it can rapidly spread through openings or gaps in these fire-rated assemblies if not properly protected. Firestop materials and installations are designed to seal these gaps, effectively restricting the movement of flames and smoke, thereby helping to protect lives, property, and allowing for safe evacuation during emergencies.

While enhancing aesthetics, reducing energy consumption, or providing structural support may be beneficial attributes of building designs or installations, they do not align with the core function of firestop systems, which is strictly focused on fire safety and containment. Understanding this distinction is crucial for professionals involved in fire protection and building safety.
