Curtain Wall Remediation

Trident Facades provides curtain wall remediation services for residential, commercial and high-rise buildings where existing curtain walling requires repair, upgrading, partial replacement or complete replacement.

Curtain wall remediation can address problems with the curtain wall system itself as well as associated components including glazing, seals, interfaces, insulation, fire stopping and cavity barriers.

What is Curtain Walling Remediation?

Curtain walling systems are used across commercial, retail, and high-rise residential building façades, providing large expanses of glass, natural light, and a lightweight external envelope. A curtain walling façade is more than the visible glazing or spandrel panels, with the complete system typically comprising mullions, transoms, glazing units, gaskets, weather seals, thermal breaks, fire stopping, perimeter seals, and structural interfaces.

The condition, configuration, and interaction of all these components should be considered when assessing the façade and determining the appropriate remediation solution.

When Is Curtain Wall Remediation Required?

Curtain walling can require remediation for a number of reasons, including:

  • Water ingress
  • Failed seals and gaskets
  • Deteriorated or corroded components
  • Defective fixings
  • Glazing defects
  • Poorly performing interfaces
  • Air leakage
  • Thermal performance problems
  • Condensation
  • Defective fire stopping
  • Inadequate cavity barriers
  • Structural or movement-related defects
  • Deterioration of the existing system

The correct remediation approach depends on the type and condition of the curtain wall system and the nature of the defect.

Our Timber Cladding Remediation Process

  • Assessment

    1

    A thorough investigation of the existing curtain wall system to identify defects, water ingress, thermal leakage, structural movement, or compliance failures.

    Reviewing existing assessment information, conducting façade surveys, opening-up and intrusive investigations, and assessing framing, glazing, seals, and fire stopping.

  • Strategy

    2

    Developing a tailored remediation plan based on the investigation findings.

    Determining whether the system requires localised gasket replacement, targeted glazing or spandrel panel upgrades, structural realignments, or broader curtain wall remediation based on performance and safety findings.

  • Design

    3

    Engineering the required remediation and specification for the building envelope.

    Developing a buildable specification covering thermal performance, acoustic ratings, structural glass tolerances, perimeter fire stopping, weather-sealing details, and regulatory compliance.

  • Removal

    4

    Safely stripping away defective or non-compliant elements of the existing façade.

    Erecting secure access platforms or cradles, carefully removing degraded glazing units, spandrel panels, failed gaskets, and inadequate perimeter seals or cavity barriers.

  • Repair

    5

    Repairing and upgrading the underlying structure, framing, and compartmentation barriers.

    Correcting structural bracket alignments, securing mullion and transom connections, and fitting certified cavity barriers and perimeter fire stopping at all critical slab edges.

  • Replacement

    6

    Rebuilding the curtain wall system to modern performance and safety standards.

    Installing new high-performance glazing or spandrel panels, continuous thermal breaks, fresh weather-sealing gaskets, and upgraded perimeter seals.

  • Completion

    7

    Final handover, quality verification, and project sign-off.

    Making good the work areas, conducting rigorous water-testing and quality inspections, and issuing the necessary completion documentation, safety certifications, and warranties.

Curtain Wall Fire Stopping

Fire stopping at curtain wall interfaces is an important consideration in many remediation projects.

Defects can occur where the curtain wall interfaces with:

  • Floor slabs
  • Compartment walls
  • External wall systems
  • Spandrel panels
  • Internal partitions
  • Adjacent façade systems

Where defective fire stopping is identified, appropriate remedial works can form part of the wider curtain wall remediation strategy.
