Key features of a fire door

Fire doors are a critical component of a building’s passive fire protection system. When correctly specified, installed, and maintained, they help prevent the spread of fire and smoke, protect escape routes, and provide occupants with valuable time to evacuate safely.
While fire doors may look similar to standard doors, they are highly engineered assemblies made up of a number of essential components that work together to deliver proven fire performance. From certification marks and fire safety signage to hinges, glazing, seals, and self-closing devices, every element plays an important role in ensuring a fire door performs as intended during a fire.
This factsheet explains the key features that identify a compliant fire door and highlights what to look for when inspecting, maintaining, or modifying fire door assemblies.
