Metrix Contractors Fire Stopping

Protecting Buildings with Passive Fire Safety Solutions

At Metrix Contractors, our Fire Stopping & Compartmentation services provide essential passive fire protection for both commercial and residential buildings. These solutions are designed to contain fire and smoke, safeguard escape routes and support compliance with UK fire safety law and building regulations.

Understanding Fire Stopping & Compartmentation

What Is Fire Stopping?

Fire stopping is the process of sealing all gaps, joints, and penetrations in fire-resisting walls, floors and ceilings to ensure that the integrity of compartmentation is not compromised. These openings commonly occur where services such as cables, pipes and ducts pass through fire-rated elements — and unless properly sealed, even small gaps can allow fire and smoke to spread quickly through a building.

The Role of Compartmentation

Fire compartmentation divides a building into separate sections using fire-resistant construction. The goal is to slow or prevent fire and smoke spreading from one area to another so occupants have time to escape and emergency services can operate safely. Compartmentation is one of the core principles of passive fire protection and contributes significantly to life safety and property protection.

Why Fire Stopping & Compartmentation Matter

Life Safety

The primary aim of fire stopping and compartmentation is to protect people inside a building. By maintaining the compartment walls and floors effectively, fire and toxic smoke are contained within a limited area — helping occupants to escape before conditions become life-threatening.

Legal and Regulatory Compliance

UK fire safety law — including the Building Regulations and Approved Document B (Fire Safety) — requires that fire resistance is not impaired by penetrations or holes in fire-resisting structures. Fire stopping is therefore a legal obligation in most building work and essential for building approvals, safety audits, and insurance purposes.

Property Protection

Containing fire and smoke also helps reduce damage to property and contents. Effective compartmentation limits the financial and operational impact of a fire incident, especially in large or multi-storey buildings.

Our Fire Stopping & Compartmentation Services

Detailed Fire Stopping Installation

We identify and seal:

  • Service penetrations (pipes, cables, ducts)
  • Linear gaps between fire-resisting elements
  • Junctions between walls and floors
  • Voids and unseen openings that could allow fire spread

We use tested, certified materials — including fire-resistant sealants, collars, fireboards and cavity barriers — installed by experienced technicians to meet or exceed regulatory standards.

Compartmentation Solutions

Our compartmentation service ensures that fire-resisting walls and floors are constructed and maintained to form continuous barriers. We carefully assess and install cavity barriers where required and make sure that building subdivisions are sealed correctly so compartmentation is effective throughout your property.
