Fire Compartmentation is an important part of the passive fire protection within the overall fire safety system of a building.
Compartmentation is achieved by dividing the premises into ‘fire compartments’ through the use of fire doors, floors and walls of fire-resisting construction, cavity barriers within roof voids and fire stopping to services that penetrate through these dividing elements.
The Critical Role of Compartmentation
Fire resisting partitions and fire doors which form the compartmentation of a building play a critical safety role and the correct type of product should be specified. Furthermore, it should be properly installed – by competent persons able to fully understand the importance of correct installation of the product in the context of fire safety.
Fire rated board systems are designed to contain fire within a compartment of a building by acting as a barrier to stop the spread of heat, smoke, fire and gases.
Fire compartmentation is one of the most effective ways to limit the spread of fire and smoke within your building.
Providing compartmentation to current Building Regulation and British Standards requirements.
Prevents the spread of fire, smoke and toxic gases
Subdivides buildings into manageable areas of risk
Provides adequate means of escape enabling time for the occupants to safely evacuate the premises.

The most common identified cause of death from a fire incident is being overcome by gas or smoke or toxic fumes. Compartment walls and compartment floors form a complete barrier between fire compartments and are required to provide a minimum degree of fire resistance This fire resistance is generally expressed in terms of the number of minutes of resistance that must be provided by different parts of a building.
Checkmate work with you to ensure:
Where an escape route needs to be separated from the rest of the premises by fire-resisting construction e.g. a dead-end corridor or protected stairway the following compartmentation should be ensured.
Doors, walls, floors and ceilings protecting escape routes are capable of resisting the passage of smoke and fire for long enough to enable people to escape the building.
Where suspended or false ceilings are provided, the fire resistance should extend up to the floor slab level above.
Cavity barriers, fire stopping and dampers in ducts should be appropriately installed.
Joints between fire-separating elements such as compartment walls or floors, should be fire-stopped to maintain the continuity of resistance; and openings for timber beams, joists, purlins and rafters, and pipes, ducts, conduits or cables that pass through any part of a fire-separating element should be kept as few in number as possible, as small as practicable; and should be fire-stopped.
Checkmate Fire can ensure that your building has adequate compartmentation by completing a full compartmentation audit and where required undertaking necessary works including:
Installation of fire doors to BS 476 Part 22
Fire stopping to BS 476 Part 24
Fire compartmentation to BS9999
Spaces that connect fire compartments, such as stairways and service shafts, must be protected to restrict fire spread between the compartments.
There are a number of additional requirements depending on the type of building, for example:
- Parts of a building that are occupied for different purposes should generally be separated from one another by compartment walls and compartment floors.
- Walls common to two or more buildings should be constructed as compartment walls.
- Compartment walls in the top storey beneath a roof should be continued through the roof space.
- Walls separating semi-detached houses or terraced houses must be compartment walls.
- Garages should be separated from attached houses by compartment walls and compartment floors.
- There are additional requirements for; flats, institutional buildings, other residential buildings and non-residential buildings.
