Compartmentation: Ceilings and Walls

Fire safety is a paramount concern for building owners and occupants alike. When it comes to passive fire protection, compartmentation is a crucial strategy that relies on using fire-resistant barriers to contain fires, limit their spread, and protect lives and property. For many of us, compartmentation may conjure up the picture of fire doors. Fire doors are, of course, a crucial element of compartmentation. However, there are many more elements to preventing the spread of fire. This guide focuses on essential aspects of fire compartmentation beyond fire doors: fire-stopping in ceilings and walls.

Understanding Fire Compartmentation


What is Fire Compartmentation?

Compartmentation is a fire safety strategy that involves dividing a building into separate compartments using fire-resistant barriers. These barriers can include fire-resistant walls, ceilings, and fire doors. The purpose of compartmentation is to contain a fire within a defined area, preventing it from spreading to other parts of the building.


Why is Compartmentation Crucial for Fire Safety?

Compartmentation is crucial for fire safety for several reasons. First and foremost, it helps protect the lives of building occupants by giving them more time to evacuate in case of a fire. Additionally, it limits property damage and can make firefighting efforts more effective by containing the fire's growth.


Legal and Regulatory Requirements

The UK enforces stringent legal requirements for compartmentation as part of its fire safety regulations. The Building Regulations specify fire-resistant standards for walls and ceilings to restrict fire and smoke propagation. The Fire Safety Act 2021 makes building owners responsible for managing fire risks and maintaining compartmentation barriers. Complying with these regulations is imperative, as failing to do so can put occupants at risk. Regular inspections and maintenance are crucial for ongoing compliance and fire safety in the UK.


The Role of Ceilings and Walls in Compartmentation


Ceilings and walls play a significant role in compartmentation by serving as barriers that prevent fires from spreading within a building. Various fire-stopping measures can be used with ceilings and walls to provide greater fire protection and help achieve compartmentation.


Fire Barriers


Fire barrier systems are specialised fire protection measures designed to prevent the spread of fire and smoke within the concealed spaces above ceilings. These voids often contain electrical wiring, plumbing, and HVAC ducts, making protecting them from fire paramount. In addition to aiding compartmentation efforts by preventing the spread of a fire, fire barriers also protect critical infrastructure within the ceiling void.


Ceiling void fire barrier systems are integral to passive fire protection, contributing to overall fire safety in buildings by containing fire and smoke within designated areas.


Fire Curtains


Fire curtains are flexible, heat-resistant barriers that automatically deploy during a fire incident. They are installed in various building types, including commercial and residential spaces, to enhance compartmentation. When a fire occurs, these curtains descend, forming a barrier that isolates specific areas, preventing the spread of flames, heat, and smoke. They are instrumental in open-plan or complex layouts where other measures may be less practical.


Fire curtain properties make them an effective fire-resistant barrier, helping reduce the spread of a fire. Therefore, they can also be used to significant effect in lofts, ceiling voids, and risers too.


Intumescent Pipe Collars


Compartmentation relies on complete fire resistance throughout walls and ceilings. If there are unprotected areas, fire can spread into other compartments. One potential area that needs extra attention with regard to this is the gaps around pipes which pass through walls. Intumescent pipe collars should be used to prevent these areas from compromising fire safety.


Intumescent pipe collars are fire protection devices that are crucial in fire stopping and compartmentation within buildings. These collars encircle pipes and ducts that pass through fire-resistant walls or floors. During a fire, intumescent materials within the collar expand and swell when exposed to heat, forming a dense, insulating barrier. This expansion seals the opening around the pipe or duct, effectively preventing the spread of fire, smoke, and hot gases to adjacent compartments.


Intumescent pipe collars are a vital component of passive fire protection, ensuring that fire remains contained in its designated area. Their rapid response to heat helps maintain the integrity of fire barriers and enhances the overall fire safety of a structure.


Intumescent Sealants


Intumescent sealants expand and create a heat-resistant, insulating barrier when exposed to high temperatures. These sealants are used to fill gaps, joints, or openings in building components, such as walls, floors, or doors. In the event of a fire, intumescent sealants swell and form a protective layer, effectively sealing the gaps and preventing the passage of flames and smoke. Their ability to rapidly expand and provide fire resistance makes them a critical component of passive fire protection systems, enhancing overall building safety by containing and limiting the spread of fire.
