Passive Fire Protection
Fire walls and floors are built to hold a fire in one place, giving people time to get out. But every building has weak points. Pipes, cables and ducts pass through those walls and floors, and joints are left where walls meet the slab above. If any of these gaps are left open or sealed with the wrong product, fire and smoke can spread straight through. Most of them are hidden above ceilings and inside risers, so nobody knows until an inspection finds them.

Passive Fire Protection Across the UK
Passive fire protection keeps your building's fire compartments working as they were designed to. It closes the routes that fire and smoke would use to spread from one area to the next, and it protects ducts that need to keep working during a fire, such as smoke extract systems.
That protects lives, keeps escape routes clear for longer and limits damage to the building. It also helps you clear fire risk assessment actions and keep the fire safety records that building owners now need.

Our passive fire protection services
Fire-Rated Duct Insulation Tested fire-resistant wraps and boards for ventilation, kitchen extract and smoke extract ductwork. They help stop fire passing along or out of a duct for a set time, often 30, 60 or 120 minutes.
Penetration Sealing Fire stopping around pipes, cables and ducts where they pass through fire-rated walls and floors. We use tested collars, wraps, batts and sealants to put each wall or floor back to its full fire rating.
Linear Gap Sealing Fire-rated seals for head of wall joints, floor edges and movement joints. They hold back fire and smoke while still letting the building move.
What is passive fire protection?
There are two types of fire protection in a building. Active fire protection does something when a fire starts, like a sprinkler spraying water or an alarm going off. Passive fire protection is built into the structure and works all the time, without needing to be switched on.
Passive fire protection includes fire-rated walls, floors, doors and ductwork, and the fire stopping that seals the gaps between them. Together, they split a building into fire compartments. If a fire starts in one compartment, the aim is to keep it there for long enough for people to escape and for the fire service to arrive.
You may also hear it called fire protection insulation, fire stopping or compartmentation. They're all part of the same job.
Why tested systems and records matter
A fire stopping product only gives its rating if it's fitted the same way it was tested. The wrong product, the wrong gap size or a missing fixing can mean it fails in a real fire. That's why our trained teams check each product's test evidence against the wall, floor, service and gap in front of them before anything is fitted.
Records matter just as much. Under the Building Safety Act, owners of higher-risk buildings must keep accurate information about their fire safety work. Every seal and protected duct we fit is logged, photographed and listed with its product and rating, so your records are complete.
When you need passive fire protection
- A fire risk assessment has flagged unsealed gaps or unprotected ducts
- New pipes, cables or ducts have been run through fire walls or floors
- Old fire stopping uses untested products, such as expanding foam
- A refit or tenant fit-out has moved partitions or services
- You're taking over a building and need to know its fire stopping is sound
- A new build or refurbishment needs fire stopping to the fire strategy
- Your building is high-rise or high-risk and needs full fire safety records

We work for building owners, managing agents, housing providers and facilities teams. We also work as a specialist subcontractor for main contractors, M&E firms and drylining contractors, and coordinate with your fire engineer so the work matches the design.
