Fire Stopping

Fire Stopping Services

CNN offer a comprehensive range of fire stopping services to ensure building compartments, walls, floors, service risers and roof voids retain their fire protection. By sealing the penetrations through walls, roofs, floors, service risers and voids, we can ensure that our client’s buildings retain their fire resistance.

Quality and Compliance Assured

We actively involve fire stopping manufacturers in Quality Assurance procedures and training, to ensure site-specific systems are designed and installed within the scope of relevant fire tests. All fire stopping systems are fully accredited and comply with the specified fire strategy and Part B building regulations.
As part of our commitment to achieving the highest possible safety standards at all our customers’ sites, we have in-house Technical Compliance Auditors who monitor and report on our installation work. These internal audits are over and above those provided by the certification bodies, giving you greater peace of mind about passive fire protection compliance at your properties.
Fire stopping has three elements: the fire-rated walls, partitions, floors or ceilings being penetrated; the cables, cable trays or conduits that make up the object creating the penetration; and the materials and methods used to seal the penetrations to prevent the spread of fire and smoke.

Every service passing through fire resistant building elements will react in a different way during a fire, so there is no single solution or product that will protect all services.
To ensure a wall or partition will provide the required fire performance, specifiers should consider:

  • Fire resistant period
  • Insulation requirement
  • Wall, floor, linear gap
  • Movement – vibration and thermal expansion
  • Mechanical strength – load bearing
