When people think about fire safety, alarms, sprinklers, and extinguishers usually come to mind first. But there’s another, less visible safety measure that plays a critical role in protecting lives and property: compartmentation.
What is Compartmentation?
Compartmentation is the division of a building into separate, fire-resistant areas (or “compartments”) using walls, floors, and ceilings designed to contain a fire to its point of origin. This is a core principle of passive fire protection.
Why it Matters
By slowing the spread of fire and smoke, compartmentation:
Gives occupants more time to evacuate safely.
Reduces damage to the building and its contents.
Allows firefighters to tackle the fire in a more controlled environment.
Common Threats to Compartmentation
Unfortunately, even the best-designed systems can be compromised by poor maintenance or unapproved installations. Examples include:
Unsealed service penetrations for pipes or cables.
Damaged or missing fire-resistant materials.
DIY repairs using non-approved products.
Maintaining Effective Compartmentation
Regular inspections are vital to ensure that all compartment barriers remain intact and effective. Any breaches must be repaired using tested, certified materials installed by trained professionals.
Our Role at R2R
At R2R Maintenance and Fire Stopping, we specialise in installing and maintaining compartmentation. Our work is fully compliant with current regulations and backed by detailed documentation, giving you peace of mind that your building is protected.
Compartmentation may be invisible day-to-day, but it’s one of the most important defenses a building can have during a fire. Investing in proper installation and maintenance could make all the difference when it matters most.
