FD30 or FD60: The Key Differences When Deciding Fire Door Specifications

Fire doors save lives and safeguard properties. When a fire breaks out in a multi-residence apartment, they prevent the spread of smoke and flames between properties, affording residents time to safely escape from the building.

Fire doors, however, are not universally identical in the level of safety they provide, so it is important to understand the difference between fire door safety grades to choose the most suitable doors for your premises. FD30 and FD60 fire doors are two of the most common products and, at Mila Maintenance, we can help you to make an informed selection to give people the best chance of survival should the unthinkable occur.

What Is The Difference Between FD30 and FD60 Fire Doors?

FD30 and FD60 doors are independently tested to withstand fire for different periods of time: for FD30, 30 minutes, and for FD60, 60 minutes. A comprehensive fire risk assessment can help to determine which grade of door is most suited to a particular building.

FD30 graded fire doors are the most common. These doors are 45mm thick and are usually installed in low rise domestic buildings and offices where a rapid evacuation is possible. In contrast, FD60 doors are 54mm thick and installed in commercial or high-rise residential buildings which take longer to fully evacuate. Doors with a higher FD rating are also often chosen in settings where it is necessary to protect assets as well as people.

Where fire doors are installed in compartment walls between separate buildings, they should offer a minimum of 60 minutes protection.

Some fire door gradings are followed by the letter S (for example, FD30S). This indicates that the door is also able to resist the ingress of low-temperature smoke as it will be fitted with additional smoke brushes and intumescent strips.
