Firestopping

— Services

Passive fire protection solutions for commercial, residential and industrial projects.

What is firestopping?

Firestopping is a critical element of passive fire protection. When pipes, cables, ductwork and other services pass through fire-rated walls and floors, openings are created that can allow fire, smoke and toxic gases to spread rapidly throughout a building. Correctly installed firestopping systems restore the fire resistance of compartment walls and floors, helping to contain fire within its area of origin and providing occupants with valuable time to evacuate safely.

— How we can help

Expert Firestopping solutions.

Service Penetration Sealing

We install tested firestopping systems to seal service penetrations through fire-rated walls and floors, helping to restore compartmentation around pipes, cables, cable trays, conduits and mixed service installations while maintaining the building’s fire performance.

Linear Gap & Joint Firestopping

Construction joints and perimeter gaps can allow fire and smoke to spread if left unprotected. We install specialist linear gap seals and movement joint systems that maintain fire resistance whilst accommodating structural movement where required.

Fire Protection Systems

Every penetration is different. We install a wide range of tested passive fire protection products—including fire batts, pipe collars, pipe wraps, intumescent sealants and specialist firestopping systems—to suit the specific application and achieve compliant, long-lasting protection.

Surveys & Remedial Works

Whether rectifying failed installations or upgrading existing buildings, we carry out firestopping inspections and remedial works to identify deficiencies, restore compartmentation and help ensure buildings remain compliant with current fire safety requirements.

FAQs

What is firestopping and why is it important?

Firestopping is a passive fire protection measure used to seal openings where pipes, cables, ductwork and other services pass through fire-rated walls and floors. Correctly installed firestopping helps prevent the spread of fire, smoke and toxic gases, preserving compartmentation and providing occupants with valuable time to evacuate safely.

What is the difference between firestopping and passive fire protection?

Firestopping is one element of passive fire protection. Passive fire protection includes fire-rated walls, floors, doors, structural protection and compartmentation systems. Firestopping specifically restores the fire resistance of walls and floors where building services create penetrations.

Where is firestopping required within a building?

Firestopping is required wherever services pass through fire-rated walls, floors and ceilings. This includes cable trays, electrical conduits, pipework, ventilation ducts and movement joints. Any opening that compromises a fire compartment should be sealed using a tested firestopping system.

Is firestopping a legal requirement in the UK?

Firestopping forms part of the Building Regulations and wider fire safety legislation. Buildings must maintain effective compartmentation to help prevent the spread of fire. Using tested firestopping systems and ensuring they are correctly installed is essential for achieving compliance.

What types of buildings require firestopping?

Firestopping is used across virtually every commercial and residential building, including offices, apartment developments, schools, hospitals, hotels, warehouses, industrial facilities, retail units and public buildings. Any building containing fire-rated compartments will typically require firestopping.

What services can be firestopped?

Professional firestopping systems can seal around a wide variety of building services, including plastic pipes, metal pipes, insulated pipework, cable trays, electrical conduits, trunking, data cabling, HVAC services and mixed service penetrations.

How long does firestopping last?

Correctly installed firestopping systems are designed to provide long-term performance throughout the life of the building. However, any subsequent alterations, new service installations or maintenance works should be inspected to ensure compartmentation has not been compromised.

Can existing firestopping be repaired or upgraded?

Yes. Older or damaged firestopping can often be removed and replaced with modern tested systems. Remedial firestopping is commonly carried out following refurbishment works, service upgrades or fire safety inspections where existing installations no longer meet current requirements.

What happens if firestopping is missing or incorrectly installed?

Missing or poorly installed firestopping can allow fire and smoke to spread rapidly between compartments, significantly reducing the effectiveness of a building’s passive fire protection strategy. It may also result in compliance issues and increase risks for occupants and property.

How do you know which firestopping system to use?

The correct firestopping solution depends on the type of wall or floor construction, the services passing through it, the required fire rating and the manufacturer’s tested system. Professional installers select products based on approved test evidence rather than a one-size-fits-all approach.

What is a fire compartment?

A fire compartment is a section of a building designed to contain fire and smoke for a specified period. Fire-rated walls and floors create these compartments, while firestopping ensures their integrity is maintained wherever services pass through them.
