Why fire stopping matters

Building compartments are designed to contain fire and smoke for a defined period. That protection can be compromised when mechanical, electrical or plumbing services pass through compartment walls and floors without the correct fire stopping.

Correctly specified and installed fire stopping helps to:

• Maintain the fire resistance of compartment walls and floors.
• Reduce the spread of fire, smoke, heat transfer and toxic gases.
• Protect escape routes and adjacent areas.
• Support Building Regulations and fire strategy requirements.
• Provide evidence for building control, principal contractors, clients and responsible persons.
• Reduce the risk of costly rework at inspection or handover.

Fire stopping should never be treated as a last-minute finishing item. It needs to be planned, installed and recorded with the same discipline as any other life safety measure.

Fire stopping systems we install

Fire Shield works with proprietary certified systems installed in accordance with relevant manufacturers’ test data and project requirements.

Typical fire stopping solutions include:

• Intumescent coated batts for service openings in fire-rated walls and floors.
• Fire compounds for service risers and penetrations where load or robustness is required.
• Intumescent mastics for joints, movement gaps and service penetrations.
• Acoustic and air sealing where fire performance, acoustic performance and air tightness need to be coordinated.
• Remedial fire stopping where existing installations are damaged, incomplete, poorly recorded or no longer suitable.

Depending on the specification and installation detail, Fire Shield’s fire stopping systems can provide up to 240 minutes of fire resistance.

Fire stopping for service penetrations

Service penetrations are a common weak point in compartmentation. A wall or floor can be designed to resist fire, but if the penetration is not sealed correctly, fire and smoke can bypass the compartment line.

Fire Shield supports fire stopping for penetrations created by:

• Electrical cables and cable trays.
• Mechanical pipework.
• Fire Dampers.
• Data and communications services.
• Service risers.
• Building movement joints and construction joints.
• Mixed-service openings.

The correct system depends on the wall or floor construction, service type, aperture size, required fire resistance, acoustic requirements, movement requirements and manufacturer test evidence.

Fire stopping, acoustic sealing and air sealing

Many project teams need more than a fire seal. Gaps around services and perimeters can also affect acoustic performance, airtightness, energy use and condensation risk.

Fire Shield’s fire stopping, acoustic and air sealing services are designed to help contractors and clients coordinate these requirements properly, reducing duplication and helping the finished building perform as intended.

Electronic logging and fire stopping records

Good fire stopping is not only about the installation. It is also about the evidence.

Fire Shield uses electronic logging and reporting to record completed installations in real time. Seal records can include location details, installation information, images and handover evidence, helping clients maintain a clearer view of progress, cost, productivity and compliance information.

This is especially valuable on complex projects where hundreds or thousands of seals need to be installed, checked and handed over across multiple areas.

Remedial fire stopping

Existing buildings often reveal fire stopping issues during refurbishment, surveys, risk assessments or planned maintenance. Common problems include missing seals, damaged materials, unrecorded service changes, unsuitable products, poor installation, or penetrations that no longer match the original fire stopping detail.

Fire Shield carries out remedial passive fire protection works to help clients correct issues professionally and with clear supporting records.

Remedial fire stopping may be required after:

• Refurbishment works.
• M&E alterations.
• Fire risk assessments.
• Compartmentation surveys.
• Building handover inspections.
• Maintenance activity.
• Changes in building use or layout.

FAQ Suggestions

What is fire stopping?

Fire stopping is the sealing of openings, joints and gaps in fire-resisting walls, floors and other compartment elements using suitable tested materials. It helps maintain the fire resistance of the compartment where services pass through.

Where is fire stopping required?

Fire stopping is commonly required around pipes, cables, dampers, service risers, construction joints, movement joints and other openings in fire-resisting construction.

Who should install fire stopping?

Fire stopping should be installed by competent specialists using appropriate systems in line with manufacturer test data, the fire strategy and project requirements.

Can fire stopping provide acoustic performance too?

Some fire stopping systems can also support acoustic performance and air sealing, depending on the product, installation detail and project specification.

Does Fire Shield provide fire stopping records?

Yes. Fire Shield uses electronic logging and reporting to capture installation records, images and handover information for completed passive fire protection works.
