The difference between FD30 and FD60 fire doors

Fire doors have become synonymous with fire protection in Britain. Their usability and utility in such untoward situations are exemplified by the fact that they are mandated in every new construction, whether it’s a house, a commercial building, or even an office, fire doors are now required by the government to be installed throughout the building in strategic places to ensure proper and efficient evacuation. Today, we’ll look at fire door ratings, specifically the differences between the FD30 and FD60 doors and what these terms mean. 

Let’s first look at what a fire door is, and why is such an important addition to residential and commercial buildings throughout the UK and elsewhere.

Fire doors: why are they so crucial?

Fire doors are installations that double as doors that can box flames in, giving residents ample time to evacuate in an orderly manner. Due to the materials used in their construction, these doors can withstand direct flames and limit the spread of the fire to other areas of the building, thereby maintaining the building’s structural integrity even when flames might be raging within the structure. 

Fire doors are crucial because they form the first line of defense if a fire breaks out within a building. The fire doors form what is called the passive firefighting system; this means that unlike active measures, which seek to put out or extinguish the fire, passive firefighting means holding or boxing in the flames to ensure a safe and quick evacuation is possible without endangering the occupants or compromising the structural integrity of the building itself that would then put the occupants at risk. 

The fire doors in the UK are rated as FD30, FD60, and FD90, which are all part of a system that gauges the resilience of these doors. Let’s look at what this rating means and what do these numbers mean.

Fire door rating: the FD standard

When shopping for a fire door, you might have seen certain designations on models like FD30 and FD60. What does this mean? Let’s look at the reasons behind these designations and what these mean from a consumer’s viewpoint.

FD rating:

 Fire doors are installed to help delay the time between the fire erupting and spreading onto different parts of a structure, where it may pose a hazard to the structural integrity of the building. This means that the door should be constructed out of materials that delay its own capitulation to the fire and maintain its structural integrity even when flames might engulf the area around it. 

The rating, therefore, is used to measure the time that the door is supposed to hold up to the flames. Now, look at what different door types and their rating titles mean.


Fire doors start from the rating of FD30. FD30 means that the fire door is rated to hold in the flames for at least 30 minutes, giving occupants sufficient building to evacuate safely. This is where the fire door safety rating starts and FD30 doors are the most common as they are the most cost-effective option on this list.


A step up from the FD30 are FD60-rated fire doors, which, as their name implies, are rated to withstand direct flames and extreme heat for up to 60 minutes without compromising their integrity. These doors are much more suitable for larger buildings and are used in places where the risk of blaze is higher than usual, and occupancy rates are also higher.


The highest-rated fire doors that are commercially available. The FD90 is supposed to stay up and block the flames for at least 90 minutes before the door’s structural integrity is compromised. Given that these doors are the highest-rated and can withstand flames and extreme heat for the longest period, the FD90 costs as such and is installed in places where emergency evacuation might require time. 

Now, it’s time we looked at FD30 vs FD60 doors and what makes them so different.

FD30 vs FD60 doors: the differences

In the case of the differences between FD30 and FD60-rated fire doors, the main difference is, of course, the resistance rating itself. The naming convention implies a difference of at least 30 minutes between the two doors and their resistance rating; the FD30 fire door will hold up to flames for 30 minutes, while the FD60 can resist direct flames for up to 60 minutes. Let’s look at some other differences. 

Fire resistance:

FD30 fire doors resist flames for up to 30 minutes, whereas the FD60 is better equipped, resisting flames for up to 60 minutes. 


FD30 fire doors are used extensively throughout buildings with low occupancy numbers and minimal evacuation time. On the other hand, FD60 fire doors are used for buildings with high occupancy numbers, and evacuation time is required. In this case, strategically placed FD60 fire doors can help with the evacuation process and will ensure that firefighters can easily bring down the flames. 

The bottom line

FD30 vs FD60 fire doors are manufactured for specific buildings and used in certain situations. With their respective abilities and construction, both doors bring in passive fire fighting and can help evacuation if anything like this happens. Given that they are mandated, you can easily factor in the building size and occupancy numbers to understand whether FD30 or FD60 fire doors will best fit you.
