Understanding Cladding Types, the NSW Product-Use Ban and Building Assessment
Cladding is an external finish or system that can contribute to weather protection, appearance, durability and building-envelope performance. Material categories include metal panels, fibre cement, masonry, terracotta, timber and composite products, but a category name does not establish the composition, evidence or suitability of a particular product.
This guide explains the difference between cladding categories, the specific NSW aluminium composite panel product-use ban and a building-specific assessment. It is general information, not a compliance determination, regulated design, fire-engineering advice or certification.
Key distinction: “combustible”, “banned”, “non-combustible” and “compliant” are not interchangeable. Identify the actual product, complete external-wall arrangement, proposed use, applicable requirements and supporting evidence.
Common Cladding Categories
Metal panels
Products may include solid metal sheets, profiled sheets, insulated panels and metal composite panels. Core composition, coatings, fixings, corrosion environment and complete-system details matter.
Fibre cement and sheet products
Review the exact sheet, thickness, fixing system, joints, coatings, substrate, exposure limits, maintenance and product evidence rather than relying on the generic category.
Masonry and terracotta
Brick slips, tiles and terracotta systems require assessment of support, anchors, movement, cavities, water management, weight and compatibility with the building.
Timber and timber-derived products
Species, treatment, profile, coating, moisture exposure, fire performance, fixings and maintenance affect suitability. A natural material label does not settle the assessment.
Composite products
Composite is a broad description. Identify facings, core or substrate, binders, thickness, tested configuration, intended use and limitations for the specific product.
Rendered and proprietary systems
Assess the complete proprietary arrangement, including substrate, insulation, mesh, coatings, flashings, joints, penetrations, fire stopping and installation requirements.
What the NSW Product-Use Ban Actually Covers
The NSW product-use ban applies to aluminium composite panels with a core comprised of more than 30 per cent polyethylene by mass when used in specified external wall, cladding, façade or rendered-finish applications on certain buildings. The ban contains defined scope, conditions and exceptions that must be checked against the current instrument and the actual product and use.
It is therefore inaccurate to say that all aluminium composite panels, all combustible cladding or every other composite product is banned. A product outside this specific ban may still require assessment against the National Construction Code, applicable standards, approvals, product evidence and project-specific design requirements.
Check the current NSW aluminium composite panel product-use ban and external-wall cladding guidance.
Separate Four Different Questions
1. What product is present or proposed?
Record manufacturer, product name, model, composition, thickness, finish, batch or date information and intended application. Generic visual identification is not conclusive.
2. Does a product-use ban apply?
Compare the identified product, building and use with the current ban’s scope and exceptions. Preserve the evidence supporting that conclusion.
3. What does the building require?
Consider classification, construction type, height, geometry, fire strategy, structural actions, exposure, weatherproofing, thermal performance, durability and approvals.
4. Is the complete system supported?
Review panels, framing, fixings, insulation, membranes, cavities, barriers, flashings, joints, openings, penetrations and interfaces against relevant evidence and design.
How Test Reports and Standards Should Be Used
A test report, certificate or appraisal is evidence within a defined scope. Confirm the exact product and tested configuration, report status, laboratory or issuing body, test method, classification, limitations, installation conditions and relevance to the proposed assembly.
AS 5113
Evidence relating to external-wall fire propagation should be read within the tested configuration and classification. It does not make every variation or building application compliant.
Combustibility evidence
A component result does not automatically determine the performance of the complete wall. Identify which component was tested and how it is used in the proposed assembly.
NCC assessment
The applicable NCC pathway and referenced evidence depend on the building and proposed work. Avoid converting one report into a blanket approval statement.
Assess Existing Buildings in a Controlled Sequence
1. Gather records
Collect drawings, specifications, approvals, fire reports, product documents, maintenance history, photographs and previous investigations.
2. Inspect and identify
Use appropriately scoped inspection, sampling and targeted opening-up where needed. Record access limits and concealed-condition uncertainty.
3. Assess the building and wall
Review the identified products, complete external wall, interfaces, condition, fire strategy, water performance and applicable requirements.
4. Define proportionate action
The next step may involve further evidence, monitoring, maintenance, risk controls, targeted repair or replacement. It should follow the findings, not a generic assumption.
5. Allocate responsibilities
Confirm who provides design, declarations, specialist assessment, certification, construction, inspections and client approvals before work proceeds.
6. Preserve the handover record
Retain approved designs, product evidence, variations, inspections, photographs, declarations, warranties and maintenance information.
Keep NSW Practitioner Roles Clear
Where the NSW Design and Building Practitioners framework applies, regulated designs, design compliance declarations, variations and building compliance declarations must be prepared or made by practitioners whose registration authorises the relevant work. Check the current Building Commission NSW design-obligation guidance.
SCE Corp can review construction scope, buildability, access, safety, staging, procurement, programme and commercial fit and coordinate suitable delivery where engaged. Product assessment, regulated design, declarations, fire engineering and certification remain with the appropriately registered or appointed parties responsible for those functions.

Frequently Asked Questions
What are the main types of building cladding?
Common categories include metal panels, fibre cement, masonry, terracotta, timber, composite products and proprietary rendered systems. The exact product, complete assembly, evidence and intended use matter more than the category name alone.
Are all aluminium composite panels banned in NSW?
No. The NSW product-use ban applies to specified uses of aluminium composite panels with a core comprised of more than 30 per cent polyethylene by mass and includes defined exceptions. Check the current ban against the actual product, building and use.
Is all combustible cladding banned?
No. Combustibility, a specific product-use ban and compliance are different questions. Products and complete external-wall systems must be assessed against the requirements and evidence relevant to the building and proposed use.
Does non-combustible cladding make an external wall compliant?
Not by itself. The complete wall, including supporting components, interfaces, building application, design, installation, evidence and approval requirements, must also be considered.
Does an AS 5113 report approve a cladding system for every building?
No. The report or classification applies within its stated tested configuration, scope, limitations and conditions. Project-specific design, interfaces and applicable requirements remain relevant.
Must every building with combustible cladding be fully reclad?
No general conclusion should be made without identifying the product, assessing the building and complete external wall and considering relevant professional findings and regulatory requirements. The proportionate response depends on the evidence.
Is there still a general NSW combustible-cladding registration requirement?
The former statewide registration framework should not be presented as a current universal requirement. Owners should check current government guidance, any council or authority correspondence and obligations applying to their specific building.
How can SCE Corp assist with a cladding project?
SCE can review construction scope, buildability, access, safety, staging, procurement, programme and commercial fit and coordinate suitable building and remedial work. Regulated design, declarations, specialist advice and certification remain with the responsible registered or appointed parties.
