Façade Insulation Replacement

Trident Facades provides façade insulation replacement services where existing insulation within an external wall system is defective, unsuitable or needs to be replaced as part of wider remediation works.

Insulation is an integral part of the external wall build-up and its replacement may need to be coordinated with cladding, cavity barriers, membranes and fire stopping.

When Does Façade Insulation Need Replacing?

Insulation replacement may form part of a remediation project where existing insulation:

Has inadequate fire performance
Is damaged or deteriorated
Has been affected by water ingress
Is incorrectly installed
Does not provide the required thermal performance
Is being replaced as part of a new wall build-up
Has been exposed during cladding removal
Cannot be retained within the proposed remediation design

Insulation Within an External Wall

External wall insulation can sit behind:

Rainscreen cladding
ACM panels
HPL panels
Render systems
Metal cladding
Other façade systems

The insulation therefore needs to work with the rest of the wall construction.

Façade Insulation Replacement Services

Our works can include:

Removal of existing insulation
Disposal
Substrate preparation
New insulation installation
Fixings
Retention systems
Membranes
Cavity barriers
Fire stopping
Interface detailing
Replacement cladding

Fire Performance

Where insulation replacement forms part of a fire-safety remediation project, the selected system needs to satisfy the requirements established by the project design and relevant technical assessment.

Fire performance cannot be considered separately from the surrounding wall construction.

The relationship between insulation, cavity barriers, cladding, membranes and fire stopping needs to be addressed as part of the complete external wall design.

Thermal Performance

Insulation replacement may also provide an opportunity to improve the thermal performance of an existing building.

The proposed wall build-up can be assessed for:

Insulation performance
Thermal bridging
Junctions
Interfaces
Condensation risk
Overall wall performance

Insulation Replacement During Cladding Remediation

Where existing cladding is removed, the insulation behind it may be exposed.

The condition of the insulation can then be assessed against the proposed remediation design.

This can result in:

Cladding Removal → Insulation Assessment → Insulation Replacement → New Wall Build-Up → Cladding Installation

Complete External Wall Remediation

Insulation replacement can be coordinated with:

Cladding replacement
Cavity barrier remediation
Fire-stopping remediation
Façade waterproofing
External wall replacement
