Fire Stopping for Renovations: Adapting to Changes in Building Use and Electrical Installations

31st January 2025

Renovations in commercial and rental properties often come with significant structural and functional changes, from repurposing spaces to updating electrical systems. While these updates improve utility and aesthetics, they can introduce new fire risks, making fire-stopping essential. This blog explores the importance of fire-stopping during renovations, particularly when adapting to new building uses and electrical installations.

Why Fire Stopping Matters During Renovations

Fire stopping is the process of sealing openings and gaps in a building's structure to prevent the spread of fire, smoke, and toxic gases. When properties are renovated, walls, ceilings, and floors may be modified or penetrated, potentially compromising the building's fire-resistant integrity. Without effective fire stopping, a fire can spread rapidly, endangering occupants and causing significant property damage.

Adapting to Changes in Building Use

Renovations often repurpose buildings for new uses, such as converting offices into apartments or warehouses into retail spaces. Each use comes with unique fire safety requirements:

  1. Increased Occupancy: Higher occupancy demands robust fire-stopping to ensure safe evacuation routes.
  2. New Compartments: Reconfiguration of spaces can create new compartments requiring fire-resistant barriers.
  3. Additional Equipment: Equipment like HVAC systems and elevators may require fire-rated enclosures or penetrations.

Ensuring fire-stopping compliance during these changes is crucial to meet building codes and protect occupants.

Electrical Installations and Fire Risk

Modern renovations often include updating electrical systems to meet current demands. However, new installations can inadvertently introduce fire hazards:

  1. Overloaded Circuits: Increased power needs can strain older wiring.
  2. Penetrations for Cabling: Electrical work often involves drilling holes, which can breach fire-resistant barriers.
  3. Improper Installation: Incorrect installation of electrical components may result in overheating or short circuits.

Fire stopping addresses these risks by sealing penetrations and using fire-resistant materials that meet stringent safety standards.

Key Fire-Stopping Solutions for Renovations

  1. Intumescent Materials: These expand when exposed to heat, sealing gaps and containing fire. Ideal for protecting cables, pipes, and ducts.
  2. Fire-Resistant Sealants: Used to close small openings around penetrations, preventing smoke and fire spread.
  3. Fire-Rated Boards: Provide a barrier in larger openings, maintaining compartmentation integrity.
  4. Collars and Wraps: Designed for pipes, these expand under heat to block fire and smoke.
  5. Fire Doors: Upgrading or installing fire-rated doors ensures safe egress during an emergency.

Ensuring Compliance and Safety

Renovations must comply with the Regulatory Reform (Fire Safety) Order 2005, which mandates comprehensive fire risk assessments. Fire-stopping measures should be documented and reviewed during these assessments to ensure they meet British safety standards. Hiring certified professionals ensures proper installation and long-term reliability.

Benefits of Fire Stopping During Renovations

  • Enhanced Safety: Reduces the spread of fire, smoke, and gases, protecting occupants and assets.
  • Legal Compliance: Helps meet building regulations, avoiding fines and legal issues.
  • Insurance Coverage: Proper fire stopping may be a condition for insurance claims.
  • Peace of Mind: Ensures that renovations do not compromise fire safety, safeguarding lives and investments.
