Curtain Wall Fire Stopping

Trident Facades provides curtain wall fire stopping services where remedial works are required at the interface between curtain walling and the building’s fire compartmentation.

Fire stopping at curtain wall interfaces can be particularly important in multi-storey buildings, where the curtain wall system passes continuously across floor levels and compartment lines.

What Is Curtain Wall Fire Stopping?

Curtain wall fire stopping is designed to maintain the required fire resistance at the interface between the curtain wall and the building structure.

Depending on the building construction, this may involve interfaces at:

  • Floor slabs
  • Compartment walls
  • Structural frames
  • Spandrel areas
  • External wall systems

The precise arrangement depends on the curtain wall construction and the fire strategy for the building.

Common Curtain Wall Fire-Stopping Defects

Problems can include:

  • Missing fire stopping
  • Incomplete installation
  • Incorrect materials
  • Gaps at interfaces
  • Poorly fitted components
  • Damaged fire stopping
  • Inadequate continuity
  • Defective interfaces between systems

A visible gap does not necessarily reveal the full extent or cause of the problem. Investigation may therefore be required before remedial works are specified.

Investigating Curtain Wall Interfaces

Our dedicated survey team can undertake targeted opening-up where necessary to establish the existing construction and condition.

This can help establish:

  • Curtain wall construction
  • Floor slab relationship
  • Existing cavity
  • Fire-stopping arrangement
  • Insulation
  • Adjacent wall construction
  • Extent of defects

Curtain Wall Fire Stopping Remediation

Depending on the findings and design requirements, remedial works may include:

  • Removal of defective materials
  • Installation of replacement fire-stopping systems
  • Sealing of gaps
  • Interface repairs
  • Replacement of damaged components
  • Installation of cavity barriers
  • Repairs to adjacent façade components

The remedial solution should be appropriate for the specific construction and supported by the relevant design and technical information.

Fire Stopping at Floor Slab Interfaces

One of the key areas requiring consideration is the junction between the curtain wall and floor slab.

The interface needs to accommodate the relationship between the façade and the building structure while maintaining the required fire performance

Fire Stopping and Façade Remediation

Curtain wall fire stopping can form part of a much wider remediation project.

For example:

Survey → Investigation → Remediation Strategy → Design → Fire-Stopping Remediation → Curtain Wall Remediation → Completion

Where wider defects are identified, the fire-stopping works should be coordinated with the surrounding façade system rather than treated as an isolated repair.

Professional Remediation

Trident Facades can coordinate investigation, design and remedial construction where a curtain wall fire-stopping defect has been identified.

If you already have a fire assessment, façade survey or report identifying defective fire stopping, we can review the available information and discuss the appropriate next step.
