HPL Cladding Replacement

Trident Facades provides HPL cladding replacement services for buildings where an existing high-pressure laminate (HPL) rainscreen system needs to be removed and replaced.

Replacement projects require careful coordination between façade design, existing wall construction, access, removal and installation

When Does HPL Cladding Need Replacing?

Replacement may be required where an existing HPL system:

Cannot achieve the required fire performance
Has delaminating, warped or bowed panels
Has swollen or degraded panel edges from moisture ingress
Has defective support rails or brackets
Suffers persistent water ingress
Has failed membranes or interfaces
Has inadequate cavity barriers or fire stopping
Cannot be effectively repaired
Is being replaced as part of a wider façade remediation programme

Designing the Replacement System

A replacement HPL system should be designed around the complete external wall.

Considerations can include:

Panel material and fire classification
Support rails
Brackets
Fixings
Insulation
Membranes
Cavity barriers
Fire stopping
Windows
Balconies
Flashings
Weathering
Thermal performance

Removing the Existing System

The existing HPL cladding must be carefully dismantled to expose the wall construction while protecting retained elements.

This may involve:

Scaffolding
MEWPs
Controlled dismantling
Panel removal
Rail removal
Disposal
Temporary weather protection
Substrate preparation

Installing the New HPL Cladding

The replacement system can then be installed in accordance with the approved design and specification.

This may include new:

HPL panels
Support systems
Insulation
Membranes
Cavity barriers
Fire stopping
Flashings
Trims

HPL Replacement as Part of Remediation

Where a FRAEW or other assessment has identified remediation requirements, the replacement design should respond to the findings and recommendations of that assessment.

Our dedicated survey team can assist with the investigation and opening-up stage where required.
