Common Misconceptions About Fire Door Assemblies
Swinging fire door assemblies protect openings in walls that are constructed to compartmentalize a building and resist the spread of fire. Without these fire doors as “opening protectives,” fire-rated walls, partitions, and barriers with door openings would be unable to deter the spread of smoke, flames, and toxic gases during a fire.
Although the requirements for fire door assemblies are addressed in the model codes, and further detailed in NFPA 80-Standard for Fire Doors and Other Opening Protectives, the Steel Door Institute (SDI) often receives questions about fire doors. This article will address a few of the misconceptions that come up the most.
