CodeMark Certification for Australian Windows and Doors: How to Verify Compliance Before You Buy

Australia’s window and door compliance framework is one of the most rigorous in the world, layered between Australian Standards, state and territory regulation, the National Construction Code (NCC), and a network of independent third-party certification schemes. For most Australian projects, AS 2047 product testing and WaterMark / S-Mark certification are sufficient evidence of compliance for council approval. For high-risk, novel or large-scale commercial projects, however, the highest level of credibility is CodeMark Certification — the voluntary but statutorily-recognised scheme administered jointly by the Australian Building Codes Board (ABCB) and JAS-ANZ, and explicitly named in NCC Volume One as “evidence of suitability” under Part A5G3.

This guide explains what CodeMark Certification is, how it differs from AS 2047 testing and S-Mark certification, when CodeMark matters for windows and doors in Australia, how to verify a supplier’s CodeMark credentials before purchase, and how MEICHEN Windows & Doors (trading in Australia as MC Windows & Doors) is pursuing expanded CodeMark coverage for its aluminium window and door systems.

1. What Is CodeMark Certification?

CodeMark Certification is the highest-level voluntary product certification scheme for the Australian and New Zealand building industry. It is administered jointly by:

• The Australian Building Codes Board (ABCB), which oversees Australian certification.
• The New Zealand Ministry of Business, Innovation and Employment (MBIE), which oversees New Zealand certification.
• JAS-ANZ, which accredits the certification bodies that issue CodeMark certificates.

CodeMark was established to address a particular gap in building product certification: products that fall outside the scope of any single Australian Standard, products that combine multiple components into systems, and products that use innovative materials or methods that need third-party verification for compliance with the Building Code of Australia (BCA) — now incorporated into the NCC.

Once a product receives CodeMark Certification, the certificate is recognised under Part A5G3 of the NCC as formal “evidence of suitability” demonstrating the product is fit for the purposes claimed by the certificate holder. Building surveyors and certifiers are required by law to accept CodeMark certificates when assessing building permit applications.

2. Why CodeMark Matters for Windows and Doors

A standard aluminium window tested to AS 2047 provides strong evidence of structural, water penetration and air infiltration performance. S-Mark certification adds factory process and quality system verification. CodeMark Certification adds the highest level of assurance: independent third-party review not only of the product but also of the manufacturer’s documentation, installation instructions, and ongoing consistency.

For windows and doors in Australia, CodeMark matters particularly when:

• The product uses an unfamiliar frame material or factory-mutual combination not covered by AS 2047 alone.
• The system is a fully assembled window-wall or curtain wall combining multiple components that need to be assessed as a single integrated product.
• The project involves high-rise or high-risk applications where additional assurance is required.
• The specifier (architect, government, large commercial builder, school or hospital) needs verifiable third-party certification recognised across all Australian states and New Zealand.

A CodeMark certificate typically covers a clearly defined scope of products (e.g., “MEICHEN MC100 Casement Window 600 mm × 900 mm to 1500 mm × 2700 mm in BCA climate zone 5 to 8”) and lists the relevant NCC clauses the product has been verified against (e.g., “Part 3.0, Part 3.1, Part 3.6, Part 3.8, Part 3.12” for fire, energy, fall prevention and weatherproofing performance).

3. The Australian Compliance Hierarchy for Windows and Doors

To put CodeMark in context, the Australian compliance hierarchy for windows and doors includes:

Level 1: Australian Standard Testing

AS 2047:2014 — the foundation standard for windows and external glazed doors. Testing to AS 2047 establishes the performance grade of a specific product size, configuration and hardware set. Testing reports are issued by NATA-accredited or ILAC-equivalent laboratories such as Azuma.

Level 2: Third-Party Verification / S-Mark

Bureau Veritas S-Mark and similar third-party certifications verify that a product not only passed a single type test but is manufactured under a quality management system and that ongoing production samples continue to meet the same performance criteria. S-Mark is widely accepted across Australia as additional evidence of fitness for purpose.

Level 3: CodeMark Certification

The highest level of voluntary certification. CodeMark requires:

• Type testing to the relevant Australian Standards.
• Quality management system audit.
• Review of installation and design documentation.
• Annual surveillance testing.
• Independent certification body review.

A CodeMark-certified window has all the assurance of an S-Mark product, plus the explicit statutory recognition in NCC 2022 Part A5G3.

Level 4: Regulatory Approval

Some products fall within mandatory schemes such as the WaterMark certification scheme for plumbing and drainage products. WaterMark is mandatory — products without WaterMark cannot be installed in regulated plumbing applications. CodeMark is voluntary but statutorily-recognised.

4. How CodeMark Differs from WaterMark

WaterMark and CodeMark are both administered under the ABCB umbrella but serve different product categories:

Note: windows and doors fall under CodeMark, not WaterMark. Some plumbing and drainage components used in door and window systems (e.g., specific sealants or fixings) may fall under WaterMark.

5. The CodeMark Certification Process for a Window System

CodeMark Certification of a window system typically follows these stages over 8 to 14 weeks:

1. Application: The manufacturer submits an application to a JAS-ANZ-accredited certification body (such as BSI, SAI Global, CertMark, Global-Mark or similar). The application includes product designs, test reports, manufacturing process documentation and proposed scope.
2. Preliminary review: The certification body reviews whether the product fits the CodeMark scheme and identifies the relevant NCC clauses.
3. Test verification: If existing test reports (e.g., AS 2047, AS 1288, AS 3959) cover the requirements, the certification body reviews them. Additional testing is commissioned for gaps.
4. Factory audit: An auditor reviews the manufacturing facility’s quality management system, production records and consistency controls.
5. Technical review: A technical reviewer evaluates the entire product dossier — designs, test reports, installation instructions, BCA/NCC compliance assessment.
6. Certification decision: The certification body’s certification committee makes the decision to grant CodeMark.
7. Certificate issuance: A Certificate of Conformity (CoC) is issued, listing the scope of certification, NCC clauses covered, and conditions.
8. Surveillance: Annual factory audits and surveillance testing ensure the certified product remains compliant.

The cost of CodeMark for a single window system is typically $20,000 to $60,000 in certification, audit and testing fees, excluding internal engineering hours — a meaningful investment that explains why only product families with significant market demand proceed to CodeMark.

6. When CodeMark Matters for Your Project

For most residential window replacement or renovation projects, AS 2047 test reports from a NATA-accredited laboratory plus, where applicable, S-Mark certification is sufficient evidence for council approval and builder acceptance. CodeMark becomes particularly important when:

• Specifying for a major commercial project: Government, healthcare, education and infrastructure projects routinely require CodeMark-certified products.
• Product is novel or non-standard: A unique window design (frameless glazing, pivot door of unusual dimensions, integrated shading system) where AS 2047 testing alone may not generalise across the product range.
• Cross-jurisdiction compliance: CodeMark is recognised identically in Australia and New Zealand — useful for specifiers managing both markets.
• In-house specifier requirement: Some large builders, housing developers and government procurement teams require CodeMark as a procurement requirement, regardless of the project’s technical complexity.

7. How to Verify a Window Supplier’s CodeMark Credentials

CodeMark certificates are publicly verifiable. Here is how to check a window or door supplier’s certification before purchase:

Step 1: Search the Register

The CodeMark Certificate Register is publicly searchable at codemark.com.au (hosted by JAS-ANZ). Search for the certificate holder (e.g., MEICHEN / MC Windows & Doors) or product name.

Step 2: Read the Certificate Scope

Each Certificate of Conformity lists:

• Certificate holder (the manufacturer).
• Certificate number.
• Product description.
• Scope of certification (sizes, configurations, options).
• NCC clauses the product is certified against.
• Conditions of certification (any use limitations).
• Issue date and validity period.

Step 3: Verify Expiry

CodeMark certificates are issued for a defined period (typically three years) and require surveillance audits to maintain validity. Always check the certificate is current.

Step 4: Cross-Reference the Audit Report

The certification body’s audit summary is often publicly available or available on request.

Step 5: Request Documentation from the Supplier

A CodeMark-certified supplier should be able to provide:

• The CodeMark Certificate of Conformity.
• Test reports supporting the certification.
• Installation instructions referenced in the certificate.
• Evidence of current surveillance audits.

Any reluctance from a supplier to provide these documents is a red flag.

8. Common Misconceptions About CodeMark

Misconception 1: “CodeMark is just a marketing badge”

CodeMark is a statutory recognition under NCC 2022 Part A5G3. Specifying a CodeMark-certified product reduces the project approval risk and the specifier’s liability. It is meaningfully more than marketing.

Misconception 2: “AS 2047 testing is sufficient for every project”

For most projects AS 2047 is sufficient evidence. But AS 2047 testing is product- and size-specific. Specifying a CodeMark-certified product extends the assurance across the full product family and configurations.

Misconception 3: “CodeMark is mandatory”

CodeMark is voluntary. WaterMark is mandatory for plumbing products. CodeMark-certified products can be installed in any Australian project; non-CodeMark products can also be installed when other evidence of suitability (such as AS 2047 test reports and S-Mark certification) is provided.

Misconception 4: “CodeMark means universal acceptance across all uses”

CodeMark certificates have defined scopes. A certificate for residential windows may not extend to high-rise or commercial uses. Always read the scope.

Misconception 5: “Once certified, always certified”

CodeMark certificates expire and require surveillance. Building surveyors and specifiers should verify currency at the time of project approval.

9. The MEICHEN / MC Windows & Doors Certification Roadmap

MEICHEN Windows & Doors (trading in Australia as MC Windows & Doors) operates a comprehensive compliance and certification program that includes:

• AS 2047:2014 testing for the core residential window and door range, conducted at NATA-accredited laboratories including Azuma.
• AS 1288:2021 compliance for all supplied glazing.
• AS 3959:2018 tested configurations for BAL-29 and BAL-40 bushfire ratings.
• AS 4145.2/3 tested door hardware.
• Bureau Veritas S-Mark certification for selected system families, confirming factory process consistency.
• AGWA (Australian Glass and Window Association) certification across 19 energy-rated window and door systems.
• CE / UKCA / NZS / JIS certifications for international markets.
• CodeMark certification currently in process for the company’s flagship residential and commercial window and door families.

MEICHEN’s certification matrix and CodeMark progress is published at mcwindow.com.au/certifications with downloadable test reports, factory audit records, and CodeMark Certificates of Conformity once issued. Specifiers, builders and homeowners can verify all certifications before purchase.

For projects where CodeMark Certification is required, MEICHEN’s engineering team is available to confirm which products fall within active CodeMark scope and which require alternative evidence of suitability — typically AS 2047 test reports plus S-Mark factory verification.

10. The Future of CodeMark for Fenestration

Several trends are pushing CodeMark coverage of fenestration products:

• Construction industry consolidation: large commercial projects increasingly require CodeMark products.
• Cross-jurisdiction sales: New Zealand-Australian manufacturers and specifiers favour CodeMark because of its mutual recognition.
• NCC updates: as NCC 2022 introduces Section J updates and Section G over-cladding reforms, CodeMark-certified fenestration products reduce the risk of specification-related rework.
• Insurer and warranty provider requirements: many product warranty providers now seek CodeMark for high-value fenestration.

Frequently Asked Questions

Q1. What is CodeMark certification?

CodeMark is a voluntary product certification scheme for the Australian and New Zealand building industry. It is recognised under NCC Part A5G3 as evidence of suitability for the relevant NCC clauses. Products that hold CodeMark can be installed in any Australian state or New Zealand with confidence that the certification has been independently verified.

Q2. How is CodeMark different from AS 2047 testing?

AS 2047 testing is product-specific type testing to one Australian Standard. CodeMark certification covers the product, the factory, the documentation and the broader NCC compliance assessment — a wider scope with stronger ongoing assurance.

Q3. Is CodeMark required for residential windows?

No. Most residential window replacements rely on AS 2047 test reports from a NATA-accredited laboratory to demonstrate compliance. CodeMark is voluntary but increasingly requested on commercial and government projects.

Q4. How do I verify a window supplier’s CodeMark certification?

Search the public CodeMark register at codemark.com.au or contact the supplier directly for the Certificate of Conformity, scope of certification, and supporting test reports.

Q5. Does MEICHEN / MC Windows & Doors have CodeMark certification?

MEICHEN has multiple AS 2047 test reports, Bureau Veritas S-Mark certification, AGWA WERS-certified systems, and is actively expanding its CodeMark certification coverage for the residential and commercial product families. Current CodeMark status for each product range is published at mcwindow.com.au/certifications.

Q6. How long does CodeMark certification take?

Typical timeframes are 8 to 14 weeks for the initial certification, with annual surveillance audits thereafter and full re-certification every three years.

Q7. Can CodeMark certification be transferred to a new factory or new product line?

No. CodeMark certification is specific to the certificate holder, factory, product family and scope. Any change in factory location, product design, or major component supplier requires certification review and may trigger re-certification.

Conclusion

CodeMark Certification is the highest level of voluntary product certification recognised under Australia’s National Construction Code. For most residential window projects, AS 2047 testing plus S-Mark factory verification is sufficient evidence of compliance. CodeMark becomes particularly valuable when specifying innovative, large-format or cross-jurisdiction products, and when the project owner or specifier wants the strongest independent assurance available.

MEICHEN Windows & Doors (MC Windows & Doors) maintains comprehensive Australian certification including AS 2047, AS 1288, AS 3959, S-Mark and AGWA WERS, with CodeMark certification actively being expanded across the residential and commercial product range. For specifiers, builders, certifiers and homeowners evaluating aluminium windows and doors for an Australian project, understanding the compliance hierarchy and verifying the supplier’s certification status before purchase reduces project risk and ensures installed products meet the relevant Australian Standards.
