Passive Fire Protection & Fire Stopping Services

NextGen is a specialist contractor providing fully integrated passive fire protection and fire stopping services for commercial and industrial projects. As an established drylining contractor, we now offer in-house fire stopping to support full fire compartmentation—delivered by qualified professionals, on time, and to the highest compliance standards.

We work directly with main contractors, helping to streamline project sequencing and reduce interface issues between trades by offering complete internal works packages.

What Is Passive Fire Protection?

Passive fire protection (PFP) refers to the systems installed within a building to contain or slow the spread of fire and smoke. Unlike active systems like sprinklers or alarms, PFP is built into the structure and is critical to ensuring safe evacuation and protecting lives and assets.

Our fire stopping services are designed to restore and maintain the fire performance of walls, floors, and ceilings that have been breached during the installation of mechanical and electrical services.

Our Fire Stopping Services

Fire Batt and Mastic Installation

We install fire-rated batt and mastic systems to seal penetrations and gaps around services in fire-rated partitions. These systems are tested in accordance with BS EN 1366-3 and are vital for maintaining compartmentation.

Applications:

  • Cable trays, pipework, ductwork penetrations
  • Walls, risers, ceilings, and floors
  • Acoustic and thermal sealing in addition to fire integrity

Fire Door Installation & Maintenance

We supply, install, and maintain certified fire doorsets (FD30, FD60) in line with BS 8214 and BM TRADA/FIRAS standards.

Services include:

  • New fire door installation
  • Retrofitting or upgrading existing doors
  • Intumescent seals, fire-rated hardware, closers & signage
  • Annual inspection and compliance reports

Fire Compartmentation Works

Our team installs systems to subdivide buildings into fire-resistant compartments, preventing the spread of fire and smoke.

Typical works:

  • Cavity barriers and fire curtains
  • Soffit and void sealing
  • Penetration seals using fire batt, ablative coating, and collars
  • Installation according to Approved Document B and BS 476
