Fire Stopping

This is an area of fire proofing to retard the spread of fire through various penetrations commonly occuring in buildings, such as cable trays, conduits, pipework, drainage systems, wiring etc. Basically, we fire seal around every service penetration in walls and floors. We normally perform this service close to the completion of buildings after all the services have been run throughout, such as electrical, aircon, water, drainage, data comms etc.




Flexible fire barriers prevent fire and smoke spread within roof and ceiling voids for all general conditions encountered on site. The vertically hung Fire Barriers are capable of achieving both integrity and insulation protection periods from 15 to 120 minutes – essential insulation performance that limits the heat transfer through the barriers.






Mineral wool Fire Batts are particularly suited for sealing around service penetrations in walls and floors, a single batt can provide high levels of fire integrity and insulation offering up to 4 hours resistance in accordance with BS4746: Part 20: 1987.







Any gaps within fire compartment walls & floors have to be sealed with suitable fire stopping materials. If not then the integrity of the compartment wall becomes compromised. We have many different types of firestopping materials available for any type of compromised situation.

Pipe collars are manufactured from a high performance material bonded to the inside of a steel sleeve, which on exposure to heat from a fire will rapidly expand inwards to squeeze the collapsing plastic pipe until the aperture is completely sealed.




Steel, copper and plastic pipes are found in all commercial and domestic buildings. A high percentage of these pipes will penetrate through fire rated constructions such as ceilings, floors and walls. Once a hole is made in a fire rated construction for the passage of pipes or services the integrity of the compartment is compromised. In a fire situation the sleeve expands to fill the available space between the pipe and the penetration. In the case of plastic pipes the sleeve will crush and close off the pipe forming a solid char and preventing the passage of fire and smoke to the adjacent compartment.
