What Homeowners Should Know About CodeMark® Certification in Australia
When you’re building or renovating, choosing the right cladding matters. You want to select materials that not only look good but also meet Australia’s strict building standards.
We’re proud to share that NewTechWood’s Shadowline and Castellation composite cladding systems are now CodeMark® certified (CM40405) — giving you confidence that your cladding meets the National Construction Code (NCC).
This quick guide breaks down what CodeMark® actually means (in plain English), how the certification works, and why it’s something worth caring about when it comes to your home.
What Is CodeMark® Certification?
It’s a government-backed certification scheme that proves a building product meets the National Construction Code (NCC) — you can call it the rulebook for how buildings are designed and approved in Australia.
Because the certification is independently checked and verified, it means the product has gone through testing by qualified experts — not just marketing claims or “trust us, it’s good.”
If your cladding has CodeMark®, it’s approved to be used in Australian homes — no guesswork needed.
Why CodeMark® Matters for Homeowners
When you’re choosing cladding, you want something that looks great and will last — but also something that won’t cause approval or warranty dramas later. Here’s why CodeMark® helps:
- Meets Australian Building Standards
CodeMark® confirms the cladding complies with NCC building rules for safety and performance. - Helps Speed Up Approvals
Builders, certifiers, and councils recognise CodeMark®, so paperwork and sign-off are often quicker and more straightforward. - Peace of Mind (No Surprises Later)
You’re choosing something that’s already been tested — not something that might become a problem down the track. - Designed for Australian Conditions
From salty coastal air to hot, dry summers, CodeMark® products like NewTechWood are proven to handle the climate.
The CodeMark® process is all about making sure the product truly meets Australian building standards — not just once, but ongoing.
Here’s what happens behind the scenes:
- Independent Testing
The product is put through official testing to check its durability, safety, and overall compliance with the National Construction Code (NCC). - Expert Assessment
Qualified building and compliance specialists review everything — from how the product is designed to how it’s installed on-site — to ensure it performs as claimed. - Ongoing Quality Checks
The certification isn’t a one-time stamp. Regular audits are done to make sure the product continues to meet the CodeMark® standards over time. - NewTechWood’s CodeMark®-Certified Cladding
Our CodeMark® Certificate of Conformity (CM40405) covers both Shadowline and Castellation wall composite cladding.
That means they’re approved as compliant under the NCC for the applications listed in the certificate — and ready to use in residential and commercial builds across Australia.
This saves time during building consent, inspection, and final sign-off — helping your project stay on track.
For homeowners, that means:
- Your cladding is tested, certified, and composite cladding compliance verified
- Builders can specify and install it faster
- Your home meets national safety and performance standards.
And with NewTechWood’s low-maintenance, fully capped composite cladding, you’ll have a product that not only meets the code but also performs beautifully year after year.
Using Certified Cladding Correctly – Notes for Homeowners
To get the best results from your CodeMark®-certified cladding:
- Ask your builder to follow the NewTechWood Installation Guide.
- Make sure he uses the cladding for the applications covered in the certificate (your builder or designer can confirm this).
- Keep a copy of the certificate (CM40405) with your project documentation for future reference.
It’s that simple — use it as intended, and you’ll enjoy the lasting performance of NewTechWood composite cladding.
