External Wall System Replacement

Trident Facades provides external wall system replacement services where an existing external wall cannot be suitably retained, repaired or upgraded.

Replacement may involve the complete external wall build-up or selected components, depending on the findings of the assessment and the requirements of the remediation strategy.

When Does an External Wall Need Replacing?

Replacement may be required where an existing wall system has:

  • Significant fire safety deficiencies
  • Defective or unsuitable cladding
  • Deteriorated insulation
  • Inadequate cavity barriers
  • Defective fire stopping
  • Persistent water ingress
  • Extensive deterioration
  • Failed support components
  • Poor thermal performance
  • Defects that cannot be effectively repaired

The extent of replacement should be established from the evidence available for the building.

What Does External Wall Replacement Involve?

A replacement project can include:

  • Investigation
  • Remediation strategy
  • Façade design
  • Existing wall removal
  • Temporary protection
  • Substrate preparation
  • New insulation
  • New membranes
  • Cavity barriers
  • Fire stopping
  • New support systems
  • Replacement cladding
  • Flashings and trims
  • Interface works
  • Installation
  • Completion

Removing the Existing Wall System

Where full replacement is required, the existing external wall components may need to be removed in a controlled sequence.

This can involve:

  • Scaffolding
  • MEWPs
  • Temporary weather protection
  • Cladding removal
  • Insulation removal
  • Removal of defective components
  • Disposal
  • Substrate preparation

See our Cladding Removal service.

Installing the New External Wall

Once the existing system has been removed and the substrate prepared, the replacement wall can be constructed in accordance with the approved design.

This may include new:

  • Insulation
  • Membranes
  • Support systems
  • Cavity barriers
  • Fire stopping
  • Cladding
  • Flashings
  • Trims
  • Interfaces

External Wall Replacement and Remediation

Replacement is often one part of a wider remediation programme.

The complete process can therefore be:

Investigation → Strategy → Design → Removal → New Wall System → Completion

Working With Existing Buildings

External wall replacement projects need to account for the building as it exists.

Existing structures, windows, balconies, internal finishes and adjacent façade systems may all affect the design and construction sequence.

This makes early investigation and detailed design particularly important.
