What is the difference between an FD30 and an FD30S fire door?

FD30 Fire DoorFire Doors are available in various fire ratings and provide different levels of protection according to the needs that apply to the use of the building and the people that use it.

At Vigor Doors, our standard Fire Doors hold a FD30 or a FD30S rating.

FD30 is the most common specification for Fire Doors leading to escape routes. These doors are built to resist fire for up to 30 minutes.

FD30S Fire Doors not only resist fire but are also able to stop the spread of cold smoke, due to them having smoke brushes in addition to intumescent strips. Smoke inhalation is the cause of death in around 42% of fire-related fatalities, so these strips on doors that FD30S-compliant Fire Doors could be the difference between life and death in some cases.

An FD30 fire door is fire resistant up to a minimum of 30 minutes, whereas an FD30S fire door is fire AND smoke resistant up to a minimum of 30 minutes. The additional S in the rating shows that the door is also smoke resistant.

What Role Do FD30s Play In Fire Safety?

Buildings are compartmentalised to delay the spread of fire from one area to another.


Usually, these compartments are linked by fire doors to allow the flow of traffic around the building.

Fire doors have two important functions in a fire. They:

1. Form a barrier to stop the spread of fire when closed
2. Provide a means of escape when opened

A well-manufactured and properly installed FD30s will delay the spread of fire and smoke without hindering the movement of people and goods around a building or workplace.

As such, all FD30s are subjected to tests to determine how capable it is of acting as a barrier to varying degrees of smoke and/or fire depending upon its location in a building and the fire hazards associated with that building.
