What is a combination of a fire door, frame, and hardware installed in a floor called?

The term used to describe a combination of a fire door, frame, and hardware installed in a floor is known as a floor fire door assembly. This assembly is crucial in maintaining fire-rated barrier requirements within a building, contributing to life safety and property protection.

A floor fire door assembly works together to provide a passageway that helps prevent smoke and flames from spreading between compartments during a fire. This assembly is specifically designed to meet regulatory standards regarding fire resistance, ensuring that it functions adequately during an emergency.

In contrast, other terms such as "F rating" refer to the classification of fire-resistance performance of a fire door and do not encapsulate the complete assembly. A "firestop" involves materials or systems used to seal openings and joints to prevent the passage of fire, which is different from a door assembly. "Floor area net" pertains to measurements of usable space in a building and is unrelated to fire safety components. Understanding the purpose and function of a floor fire door assembly is essential for ensuring compliance with safety codes and enhancing overall building safety.
