Understanding Fire Doors
Fire doors are specially designed doors that can help prevent the spread of fire and smoke between different areas of a building. They are constructed using fire-resistant materials and are designed to close automatically in case of a fire, forming a barrier that can prevent the spread of flames and smoke.
Types of Fire Doors
There are different types of fire doors, including:
- Flush fire doors: These are the most common type of fire door, featuring a flat surface with no raised or lowered panels.
- Panelled fire doors: These doors have raised or lowered panels and can be a more aesthetically pleasing option.
- Glazed fire doors: These doors have fire-resistant glass panels, allowing light to pass through while still providing fire protection.
Fire Door Regulations
It is important to ensure that your fire doors meet all building codes and regulations. This includes regulations related to the type of door, its rating, and its installation. Failure to comply with building codes and regulations can result in serious consequences in case of a fire, including loss of life and property damage.
The latest fire door regulations in the UK are outlined in the Fire Safety (England) Regulations 2022, which require all fire doors to be installed to certain standards and tested by a third-party certification scheme. It came into effect in January 2023, with new requirements for Fire Doors in multi-occupied residential buildings. Additionally, fire doors must comply with British Standards and Building Regulations.
Fire Door Components
Fire doors consist of several components, including the door leaf, frame, hinges, intumescent strips, and door closers. Each component plays a crucial role in ensuring the door can effectively prevent the spread of fire and smoke.
Let’s take a closer look at each of these components:
- Door leaf: The door leaf is the actual door itself, and it must be constructed from materials that are capable of withstanding the heat and flames of a fire. Fire-rated door leaves are typically made from materials such as timber, steel, or composite materials, and are designed to prevent the spread of fire for a specified period.
- Frame: The door frame must also be constructed from materials that are capable of withstanding the heat and flames of a fire. It must be installed securely and tightly to prevent any gaps between the frame and the wall, as these gaps can allow smoke and flames to spread.
- Hinges: The hinges on a fire door must be capable of withstanding the weight of the door leaf, as well as any additional weight from hardware such as door closers. They must also be constructed from materials that are capable of withstanding the heat and flames of a fire.
- Intumescent strips: Intumescent strips are strips of material that are installed around the edges of the door leaf and expand when exposed to heat. These strips help to seal the gaps between the door leaf and the frame, preventing smoke and flames from spreading.
- Door closers: Door closers are devices that are installed on fire doors to ensure that they close automatically and securely in the event of a fire. They must be installed correctly and adjusted to the appropriate level of resistance to ensure that the door closes effectively.
Choosing the Right Fire Door
When choosing a fire door, it is important to consider factors such as the door’s rating, the material it is made of, and the type of opening mechanism it features. It is also important to consider the size of the door, as well as its location within the building.
Measuring for Fire Doors
Accurate measurements are crucial for ensuring that your fire door fits correctly within the door frame. To measure for a fire door, you will need to measure the width, height, and thickness of the door opening. It is also important to measure the height and width of the existing door frame, as well as the depth of the frame.
Preparing the Door Frame
Before installing a fire door, it is important to prepare the door frame to ensure it is in good condition and meets all necessary regulations. This may involve removing any existing doors and hardware, as well as repairing or replacing any damaged or deteriorated wood.
Preparing the Door
Preparing the fire door involves ensuring that it is properly aligned, that all hardware is attached correctly, and that any holes or gaps are filled with appropriate sealant. This may also involve trimming the door to ensure it fits correctly within the frame.
Installing the Fire Door
To install a fire door, you will need to attach the hinges and other hardware to the door, and then install the door into the frame. It is important to ensure that the door is properly aligned and that all hardware is securely attached.
Testing the Fire Door
After installing a fire door, it is important to test it to ensure that it is functioning correctly. This may involve testing the door’s ability to close and latch, as well as testing the effectiveness of any intumescent strips or other fire-resistant materials.
Maintaining Fire Doors
Regular maintenance is crucial for ensuring that your fire doors remain effective. This may involve checking the door’s seals and hardware, testing the door’s ability to close properly, and repairing or replacing any damaged or worn components.
Fire Door Accessories
There are several accessories that can enhance the effectiveness of your fire doors, including smoke seals, intumescent grilles, and automatic door closers. These accessories can help prevent the spread of fire and smoke, and can also make your fire doors more convenient and easy to use.
Fire Door Maintenance Checklist

Fire Door Certification
Fire door certification is important for ensuring that your doors meet all necessary regulations and standards. Certification may involve testing the door’s fire resistance, as well as ensuring that it meets all necessary building codes and regulations.
In the UK, there are several certifications and standards that apply to fire doors. These include:
- BS 476: Part 22: 1987 – Fire tests on building materials and structures. Method for determination of the fire resistance of non-loadbearing elements of construction
- BS EN 1634-1: 2014 – Fire resistance and smoke control tests for door and shutter assemblies, openable windows and elements of building hardware. Fire resistance tests for doors and shutters
