Definition of FD 20 Fire Doors
An FD 20 fire door is a type of fire-rated door designed to withstand the spread of fire for up to 20 minutes. These doors are designed to slow down the progress of flames and smoke, providing occupants with sufficient time to exit a building safely during a fire emergency. They are commonly used in both residential and commercial properties, providing essential protection in the event of a fire.
Fire doors, such as the FD 20, are made using special materials, including fire-resistant glass, steel, and timber, which are treated to meet strict safety standards. They are equipped with seals that expand when exposed to heat, helping to block smoke and prevent fire from seeping through. In addition, FD 20 fire doors come with a self-closing mechanism, ensuring that the door remains closed and effective during a fire, reducing the risk of fire spreading into other areas.
It’s essential to understand that an FD 20 fire door doesn’t mean it’s fireproof; it simply means that it can contain the fire for 20 minutes, allowing sufficient time for people to evacuate safely. After 20 minutes, the door may not be able to withstand further exposure to fire, which is why choosing the right fire door rating for your building is crucial.
FD 20 vs FD 30 and FD 60
When comparing FD 20 doors to other fire doors, such as FD 30 and FD 60, it’s essential to understand the difference in fire-resistance ratings. The FD rating system refers to the duration (in minutes) a fire door can resist fire and smoke.
FD 20:
As we’ve mentioned, FD 20 doors provide 20 minutes of fire protection. They are typically used in areas where fire safety is essential, but the risk of a significant fire spreading quickly is lower. These doors are commonly found in residential homes, smaller commercial spaces, and areas with low foot traffic. They strike a balance between cost and fire protection, making them a practical choice for many buildings.
FD 30:
FD 30 doors offer a higher level of protection than FD 20 doors. They resist fire for 30 minutes, making them ideal for high-risk areas such as corridors, stairwells, and larger commercial properties. These doors are necessary when you need extra protection in spaces with a high number of occupants or valuable property.
FD 60:
FD 60 doors are designed for even longer fire resistance, providing up to 60 minutes of protection. These doors are most often used in high-risk commercial buildings, such as factories, large office blocks, and areas with hazardous materials. They offer a longer window for evacuation and can stop the fire from spreading to larger parts of a building for a more extended period.
The choice between FD 20, FD 30, and FD 60 fire doors depends on several factors, including the building’s size, the level of fire risk, and the specific regulations in effect. While FD 20 doors offer good protection, they may not be sufficient in high-risk or high-traffic areas where a longer duration of fire resistance is required.
It’s also important to consider the overall fire safety strategy of your building. Fire doors are just one part of the system. Other elements, such as fire alarms, sprinkler systems, and fire exits, work together to ensure everyone’s safety in the event of a fire.
Key Features of FD 20 Door
Fire Resistance and Protection
One of the main features of an FD 20 fire door is its ability to resist fire for up to 20 minutes. This makes it an essential safety feature in many buildings. The door’s fire-resistant materials, such as specially treated timber, steel, or glass, are designed to prevent the spread of fire and smoke, giving people more time to evacuate.
The 20-minute fire resistance rating is significant because it allows the door to contain the fire for a limited time. During this period, it slows the spread of flames and smoke, reducing the danger to people inside the building. It is crucial to understand that FD 20 doors are not fireproof but fire-resistant. They can only withstand fire for a short period, which is why they are often used in areas with lower fire risks or as part of a larger fire safety system.
FD 20 fire doors are beneficial in places such as apartments, small office spaces, or rooms that don’t require a higher rating, like FD 30 or FD 60. In such settings, FD 20 doors strike the right balance between cost and safety, providing sufficient protection for those in the building.
Closing Mechanisms and Seals
Another essential feature of FD 20 fire doors is their self-closing mechanism. These doors are designed to automatically close when released, ensuring they stay shut during a fire. This is crucial because a closed door can limit the amount of oxygen reaching the fire, slowing its spread. If a fire door is left open, the fire may spread more quickly, making it even more dangerous.
Fire doors also include fire-resistant seals. These seals expand when exposed to heat, filling any gaps around the edges of the door. This is important because even small gaps can allow smoke or fire to pass through. The seals ensure that the door remains tightly sealed during a fire, preventing the spread of harmful smoke and flames into other parts of the building. They help maintain the integrity of the fire door and increase its effectiveness in protecting lives.
There are various types of fire seals used in FD 20 doors, including intumescent seals, which expand when heated, and smoke seals, which help prevent smoke from seeping through. Depending on the environment, these seals may be placed around the edges or within the door itself to ensure a secure seal when the door is closed.
Certifications and Standards
In the UK, for example, FD 20 doors must comply with the British Standard BS 476 or the newer European standard EN 1634. These standards assess the fire resistance of the door based on its materials, construction, and ability to prevent the passage of fire and smoke. A certified FD 20 door will have a label or certificate showing that it meets these standards.
In addition to fire resistance, FD 20 fire doors must also comply with regulations related to smoke control, safety, and installation. Certification bodies such as the BSI (British Standards Institution) or the LPCB (Loss Prevention Certification Board) ensure that fire doors meet these strict requirements. These certifications help guarantee that the fire door will perform as expected in a real-life fire situation.
Choosing a certified FD 20 door is crucial for ensuring safety. Non-certified doors may not offer the same level of protection and could put lives at risk. Always ensure that the fire doors you purchase have been appropriately tested and certified by a recognised authority.

FD 20 Doors in High-Risk Areas
While FD 20 doors are suitable for many environments, they may not be the best choice for high-risk areas. In areas with higher fire hazards, such as factories, warehouses, or large commercial kitchens, fire-resistant doors with higher ratings, like FD 30 or FD 60, are typically required. FD 20 doors, offering only 20 minutes of protection, may not be enough to contain a fire in these areas for an extended period, which is why higher-rated fire doors are required.
In high-risk areas, fire doors must resist flames and smoke for more extended periods, allowing people more time to evacuate and preventing widespread fire damage. Areas such as chemical storage rooms, laboratories, and industrial facilities are prime examples where FD 20 doors may not provide adequate protection. In these settings, FD 30 or FD 60 doors are preferred for better fire containment.
However, FD 20 doors can still be helpful in high-risk areas if they are part of a larger fire safety system. For example, in large buildings with multiple fire zones, FD 20 doors can act as secondary barriers between areas of low fire risk, helping to slow down the fire’s spread, while higher-rated doors protect the more critical zones. Additionally, FD 20 doors may be used for access routes or emergency exits, where they help compartmentalize the fire without being the primary means of protection in high-risk areas.
Maintenance and Care of FD 20 Doors
Regular Inspections for Fire Doors
To ensure that your FD 20 fire door continues to perform at its best, regular inspections are essential. A fire door can only protect you effectively if it remains in good condition; therefore, it’s necessary to inspect it regularly. Fire doors should be checked at least once a year; however, if the door is located in a high-traffic area or experiences heavy use, it may require more frequent inspections.
During an inspection, pay attention to the door frame, hinges, seals, and mechanisms. Ensure the door closes properly and fits tightly in the frame. Any gaps, even small ones, can allow smoke or flames to pass through during a fire. Check that the self-closing mechanism operates smoothly and that the door closes properly after being released.
Next, inspect the fire-resistant seals around the door’s edges. These seals expand when exposed to heat, helping to prevent smoke and fire from spreading. Over time, seals can wear out, so it’s essential to check for any damage or gaps. If you notice any issues with the door’s seals or closing mechanism, repair or replace them as soon as possible to maintain the integrity of the fire door.
Finally, check for any physical damage. The door should not have any cracks, holes, or severe dents. If the door is damaged, it may not provide the protection it’s meant to.
By regularly inspecting FD 20 fire doors, you can ensure they remain effective and reliable in case of an emergency.
