What is Fire Compartmentation?

Fire Compartmentation Fire Doors

Fire Compartmentation is an important part of Passive Fire Protection. Providing compartmentation to current Building Regulation and British Standards requirements involves sub-dividing buildings into manageable areas of risk, thereby preventing the spread of fire, smoke and toxic gases and providing valuable time to evacuate the building.

Compartmentation is achieved by dividing the premises into ‘fire compartments’ by:

  • fire doors

  • floors and walls of fire-resisting materials and construction

  • cavity barriers within roof voids

  • installing a fully tested fire stopping system to ensure services such as cables, ducts and pipe work are sealed where they breach compartment walls and floors.


The Meritas Fire Compartmentation Service:

  • Meritas can install the most effective fire wall and fire stopping systems in Essex and London

  • We will conduct detailed site inspection to ascertain whether adequate fire compartmentation is in place. We will check that:

    • Doors, walls, floors and ceilings protecting escape routes can resist the passage of smoke and fire for long enough to enable people to escape the building. 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.

    • Fire resistance of suspended or false ceilings extend up to the floor slab level above.

    • Cavity barriers, fire stopping and dampers in ducts are appropriately installed.

  • Our team of expert engineers can carry out any necessary remedial or installation works to ensure the integrity of your building, thereby meeting legislation and building regulations.
