Protecting Buildings with Expert Fire Stopping Solutions Across the UK

At CS Passive Fire, we specialise in fire stopping services to prevent the spread of fire and smoke through gaps, joints, and service penetrations in building structures. Our certified fire-stopping solutions comply with UK Building Regulations, BS 476, and the Regulatory Reform (Fire Safety) Order 2005.

What is Fire Stopping?

Fire stopping involves installing fire-resistant materials to seal openings and joints in fire-rated walls, floors, and ceilings. These measures help maintain the building's fire compartmentation, containing fire and smoke within designated areas to protect occupants and property.

Why is Fire Stopping Important?

  • Limits Fire & Smoke Spread: Prevents fire from moving through walls and floors.

  • Ensures Safe Evacuation: Maintains clear escape routes for occupants.

  • Regulatory Compliance: Meets legal obligations under the Fire Safety Order 2005.

  • Preserves Structural Integrity: Helps maintain the effectiveness of fire-rated components.

  • Reduces Damage: Minimises fire-related damage to the building.
