Window Replacement

Trident Facades provides window replacement services for buildings where existing windows need to be replaced as part of façade refurbishment, improvement or remediation works.

Replacement can involve individual windows, selected elevations or larger building-wide programmes.

When Do Windows Need Replacing?

Window replacement may be required where existing windows have:

Reached the end of their serviceable life
Persistent water ingress
Failed seals
Damaged frames
Poor thermal performance
Significant deterioration
Defective interfaces
Inadequate performance
Damage that cannot be economically repaired

Windows may also need replacing where they form part of a wider external wall remediation programme.

Window Replacement as Part of Façade Remediation

Replacing windows can form part of a larger external wall project involving:

Cladding replacement
Insulation replacement
Curtain wall replacement
Waterproofing
Fire stopping
External wall system replacement

The window and surrounding façade therefore need to be considered together.

Window Replacement Design

A replacement window needs to work with the existing or proposed wall construction.

Design considerations can include:

Window type
Frame material
Glazing
Thermal performance
Weather resistance
Air permeability
Structural interfaces
Fire performance where applicable
Flashings
Membranes
Sealants
Internal and external finishes

Removing Existing Windows

Removal works can include:

Protection of occupied areas
Removal of glazing
Frame removal
Disposal
Opening preparation
Substrate repairs
Temporary weather protection

The sequence needs to be coordinated with the surrounding façade works.

Installing Replacement Windows

New windows can then be installed in accordance with the approved design and specification.

Associated works may include:

Frames
Glazing
Flashings
Membranes
Perimeter seals
Insulation
Fire stopping
Internal reveals
External finishes

Window Replacement in Occupied Buildings

Many window replacement projects involve occupied residential or commercial buildings.

The construction programme therefore needs to consider access, protection, weather, occupant safety and sequencing.
