Fire Rated Door: Types Uses Benefits & Buying Guide play an important role in passive fire protection. They help slow the spread of fire, smoke, and heat from one area of a building to another. As a result, they can give occupants more time to evacuate safely during a fire emergency.
Unlike ordinary doors, a fire rated door uses specially designed materials and components to resist fire for a specified period. Moreover, manufacturers test the complete door assembly with its frame, seals, hardware, and other components to achieve the required fire performance.
Therefore, building owners, contractors, architects, and fire safety professionals commonly use fire rated doors to protect critical areas and maintain fire compartmentation.
Commercial buildings, offices, hospitals, hotels, factories, warehouses, shopping malls, schools, apartment buildings, stairwells, corridors, electrical rooms, generator rooms, server rooms, and industrial facilities can all use fire rated doors as part of their fire protection strategy.
What Is a Fire Rated Door?
A Fire Rated Door is a specially designed door assembly that helps resist the spread of fire and, where required, smoke between designated areas of a building.
A fire rated door does more than simply use fire-resistant material. Instead, the complete door assembly must work together to provide the required fire performance.
A typical fire rated door system can include:
- Fire rated door leaf
- Fire rated door frame
- Intumescent seals
- Smoke seals
- Fire rated hinges
- Door closer
- Fire rated locks
- Latching mechanism
- Panic hardware
- Fire rated glass
- Vision panel
- Door coordinator
- Automatic release mechanism
- Electromagnetic hold-open device
- Fire rated threshold
- Compatible fixing hardware
Furthermore, every component can affect the performance of the complete assembly. Therefore, installers should use compatible components according to the manufacturer’s approved system and installation instructions.
How Does a Fire Rated Door Work?
A fire rated door separates one area of a building from another. During normal conditions, the door provides controlled access between these areas. However, during a fire, the closed door helps restrict flames, heat, and hot gases from moving into the protected area.
Furthermore, intumescent seals react to high temperatures. As the temperature increases, these seals expand and help close gaps around the door.
A suitable door closer also helps return the door to the closed position after someone opens it. Consequently, the door can maintain the separation between two areas when an emergency occurs.
In addition, smoke seals can help reduce the movement of smoke through the door assembly when the approved system includes smoke-control performance.
Therefore, the door, frame, seals, hardware, and surrounding construction must work together as part of the building’s passive fire protection system.
However, occupants should never permanently wedge or prop a fire door open. Doing so can prevent the door from providing its intended protection during a fire.
Types of Fire Rated Doors
