What is the primary purpose of firestop systems in construction?

The primary purpose of firestop systems in construction is to prevent the spread of fire, smoke, and heat through openings in fire-rated barriers. Firestop systems are critical components of fire protection engineering, designed to maintain the integrity of fire-rated walls, floors, and ceilings. These systems consist of various materials and methods that seal penetrations or joints in fire-resistance-rated assemblies, effectively compartmentalizing the fire and preventing it from spreading to other parts of the building. By achieving this, firestop systems help to protect lives, property, and minimize damage during a fire incident, ensuring that occupants have the necessary time to evacuate safely and that first responders can effectively manage the fire.
