What is Fire Stopping?
Fire-stopping is a term used to refer to the sealing of gaps in building construction, including those around services, for the purpose of maintaining fire compartmentation and separation.
Typically it includes:
- Penetrations seals – used around services through walls and floors
- Linear joint seals – seals between two separating elements such as two walls or a wall and floor
- Small cavity barriers – seals between the inner and outer leaves of a cavity wall
- Large Cavity barriers – separates larger spaces such as roof spaces or ceiling voids
- Ventilated/open state cavity barriers – seals between the inner and outer leaves of a cavity wall where ventilation is required
- Air transfer grilles – seals that allow air flow in cold state but prevent fire spread
Our process and attention to detail pre construction enables us to:
- Reduce the number of unknown variables for both our clients and their residents
- Establish a clear and defined structure of the project
- Confirm timelines and offer opportunity for third party auditing
- Minimise the risk and disruption to relevant persons
Our methodology is to:
- Review the fire strategy documents and fire strategy plans in conjunction with the M&E specifications
- Ensure early engagement with manufacturers
- Select firestopping products which are third party certified by a UKAS accredited organisation
- Request copies of standard details and test evidence to provide a tested solution
- Follow approved guidance such as the ‘Design process for penetration seals’
The information subsequently enables our clients to demonstrate to the Building Safety Regulator, Residents, Duty holders, Shareholders, Insurers and Local Authority Fire & Rescue that they have exercised due diligence and have done all that is reasonably practicable to ensure the safety of relevant persons.
