What is the main difference between a firestop seal and a fire barrier?

The main difference between a firestop seal and a fire barrier is that a firestop seal provides a localized treatment at specific points of penetration, such as where pipes, ducts, or cables pass through fire-rated walls or floors. This ensures that any openings, which could allow fire and smoke to spread, are effectively sealed to maintain the integrity of the fire-resistance rating of the assembly.

In contrast, a fire barrier is a continuous construction element designed to enclose an area and provide a means of preventing the spread of fire and smoke throughout a building. Fire barriers are typically constructed of materials such as concrete, gypsum wallboard, or masonry and extend from one floor to the next or from one side of the building to another, forming a comprehensive defense against fire spread.

Understanding this distinction is crucial for fire safety professionals, as it informs how to properly implement firestopping measures and ensure code compliance in construction and building maintenance.
