When you’re building or renovating in Australia, there’s one phrase you’ll hear a lot: AS2047 certification.
It might sound technical, but in simple terms, it’s proof your windows and doors meet Australian standards for strength, safety and weather resistance.
Without it, your project risks delays, failed inspections, or even issues with your occupancy permit.
- What is AS2047 certification?
AS2047 certification shows that a window or door system has been properly tested under the Australian Standard AS2047: Windows and external glazed doors in buildings.
Testing covers things like:
l Structural strength (can it handle Aussie wind loads?)
l Water tightness (does it leak in heavy rain?)
l Air infiltration (is it drafty?)
l Ease of operation (does it open and close properly?)
In short, it’s proof the product isn’t just “good looking” — it’s built to last in Australian conditions.
- When do you actually need AS2047 certified windows?
This is a common question we get from homeowners and builders.
Here’s a quick rundown of where it comes into play:
l Design & energy assessment
Your energy assessor may ask for WERS ratings and glass data to model your home’s star rating.
l Building permit application
Certifiers often want to see AS2047 certificates before they sign off.
l Ordering your windows
Make sure the products match your site’s wind rating and conditions. Only AS2047 certified systems guarantee that.
l Installation & inspections
Inspectors may check compliance paperwork on site.
l Final occupancy certificate
Councils or private certifiers confirm everything complies before you can move in.
From the very start of design through to getting your keys, AS2047 certification is a must-have.
- Other Australian standards to know
AS2047 is the big one, but it’s not the only standard that matters.
At RS Doors & Windows, our aluminum windows and doors are certified to:
l AS1288 – Glass selection & installation
l AS2208 – Safety glazing
l AS4666 – Insulating glass units
Together, these cover glass safety, double glazing performance, and installation compliance. Having all of them in place gives you a full compliance pack that keeps certifiers happy and your project moving.
- How this links with WERS and energy ratings
While AS2047 proves strength and weather performance, WERS (Window Energy Rating Scheme) shows how your windows affect heating and cooling.
WERS ratings include U-values and SHGC numbers — the exact figures your energy assessor will use to meet 7-star NatHERS targets.
So, AS2047 certification + WERS rating = the perfect combo for approvals.
- The paperwork you should expect
If you’re shopping for windows, always ask suppliers for:
l AS2047 compliance certificate
l Glass certificates (AS1288, AS2208, AS4666)
l WERS energy rating reports
l Installation instructions
Having this upfront avoids headaches later. If a supplier can’t show you these, that’s a red flag.
Think twice if you really need to buy windows & doors from that supplier who might avoid your project moving.
- Quick checklist for builders & homeowners
✔ Ask for AS2047 certification
✔ Double-check glass complies with AS1288 / AS2208 / AS4666
✔ Get the compliance pack before ordering
✔ Make sure windows are rated for your site conditions
- FAQ
Q: Is AS2047 certification mandatory?
Yes — it’s the recognised way to show compliance under the National Construction Code (NCC).
Q: What happens if my windows don’t have AS2047 certification?
They may fail inspections, delay your building permit, or stop you from getting an occupancy certificate.
Q: Do I also need WERS ratings?
Most likely, yes. AS2047 proves safety and strength; WERS covers energy efficiency. Both are important for new builds.
