Fire Stopping Installation

Expert Fire Stopping Solutions for Maximum Protection

Fire stopping is a critical component of a building’s passive fire protection system, designed to prevent the spread of fire and smoke through gaps, voids, and penetrations in walls, floors, and ceilings.

Properly installed fire-stopping solutions help contain fire within compartments, reducing damage and providing occupants with more time to evacuate safely.

At Overbrook, we provide specialist fire stopping installation in compliance with Approved Document B, BS 476-20/22, and BS EN 1366-3/4.

Our expert team ensures that all fire stopping materials are correctly installed to maintain the integrity of fire compartments in commercial, residential, and industrial buildings.

What Is Fire Stopping?

Fire stopping involves sealing any gaps, joints, or penetrations within fire-rated walls, floors, and ceilings to maintain fire compartmentation. These gaps can be created by:

  • Mechanical and electrical services (cables, pipes, and conduits passing through fire-rated structures)
  • Expansion joints and movement gaps
  • Openings around ductwork and ventilation systems
  • Wall and floor junctions

If left unprotected, these voids can allow fire and smoke to spread rapidly, compromising escape routes and increasing damage to property.

Why Fire Stopping Is Essential

Compliance with UK Fire Safety Regulations

Under the Regulatory Reform (Fire Safety) Order 2005, all buildings must have adequate fire-stopping measures in place. Our installations comply with:

  • BS EN 1366-3/4 – Fire resistance testing for service penetrations and linear gaps.
  • BS 476-20/22 – Fire testing standards for construction elements.
  • Approved Document B – UK building regulations for fire safety.

Preventing Fire and Smoke Spread

Effective fire stopping seals all service penetrations, joints, and voids, helping to contain fire and smoke within designated compartments and prevent uncontrolled spread.

Protecting Escape Routes and Structural Integrity

By maintaining compartmentation, fire stopping protects escape routes, giving occupants more time to evacuate safely while reducing fire damage to the building structure.
