Façade Fire Stopping Remediation

Trident Facades provides façade fire stopping remediation services where defective or incomplete fire-stopping arrangements have been identified within or around an external wall system.

Remedial fire stopping needs to be considered in the context of the complete façade and the building’s compartmentation strategy.

Where Can Façade Fire Stopping Defects Occur?

Fire-stopping problems can occur at interfaces involving:

External walls
Curtain walling
Floor slabs
Compartment walls
Windows
Cladding systems
Service penetrations
Cavity barriers
Spandrel areas
Structural interfaces

Common Fire-Stopping Problems

These can include:

Missing fire stopping
Gaps
Incomplete installation
Damaged materials
Incorrect installation
Poor interfaces
Unsealed penetrations
Defective perimeter arrangements
Fire stopping disturbed during later works

The extent of a defect cannot always be established visually, particularly where fire stopping is concealed.

Investigating Fire Stopping

Where necessary, targeted opening-up can expose concealed interfaces and establish the existing construction.

Our survey team can undertake intrusive investigation to help establish:

Existing wall build-up
Location of barriers
Fire-stopping arrangements
Floor and wall interfaces
Insulation
Cladding
Extent of defects

Fire Stopping Remediation

Depending on the findings and approved design, remedial works can include:

Removal of defective materials
Installation of replacement fire stopping
Sealing of gaps
Interface repairs
Perimeter fire stopping
Remedial work around openings
Coordination with cavity barriers
Coordination with cladding and insulation

Fire Stopping and External Wall Remediation

Fire stopping should be considered alongside the surrounding wall system.

For example, replacing cladding may expose or disturb existing fire-stopping arrangements. Similarly, insulation replacement can affect interfaces that need to be addressed as part of the remediation.

A coordinated approach can therefore follow:

Investigation → Assessment → Design → Fire-Stopping Remediation → External Wall Remediation

Curtain Wall Fire Stopping

Curtain walling presents particular interface considerations at floor slabs and compartment boundaries.

For projects involving curtain walling, see our dedicated Curtain Wall Fire Stopping service.

Complete Fire-Safety Remediation

Where fire-stopping defects form part of a wider external wall problem, Trident Facades can coordinate the remedial works with other façade packages.
