Performance label (AS 2047 windows/doors)
AS 2047 performance label is permanently affixed to every window/external glazed door showing wind class, water rating, air rating. No label, no install.
Ask Chalkline about this →A performance label under AS 2047:2014 is the permanent label affixed to every window and external glazed door product showing the unit’s tested performance ratings: wind class, water penetration resistance, air infiltration, and operating force (where applicable). It is the single visible compliance check the builder uses to verify that the installed window matches the engineering specification for the site. Without a current and legible AS 2047 performance label, the product cannot be installed in a compliant build (verified per AS 2047:2014, 2026-05-16).
Mandatory fields on the label:
| Field | Example value |
|---|---|
| Manufacturer name and address | ABC Windows Pty Ltd, Sydney NSW |
| Date of manufacture | 2026/04 |
| Wind classification | N3 (from AS/NZS 1170.2) |
| Water penetration resistance | 350 Pa |
| Air infiltration | 1.5 L/s/m² at 75 Pa |
| Operating force (where applicable) | 110 N |
| Glass type | Toughened, 6 mm (or laminated, etc.) |
| AS 2047 compliance statement | ”Complies with AS 2047:2014” |
| AGWA membership (where applicable) | Australian Glass and Window Association |
Where the label sits:
The label location must be permanent and visible after installation. Typical locations:
- Aluminium windows: inside face of the head, on the sash edge, or on the cilco bar.
- Timber windows: stencilled or stuck on the head jamb interior side.
- Sliding doors: along the top of the fixed panel, internal face.
- Hung windows: jamb interior side.
Builder’s pre-installation check:
A site procedure should require, before any window/door installation:
- Verify the wind class against the structural engineer’s wind classification on the drawings (commonly N1-N4 in temperate residential; N4-N6 or C1-C4 in cyclone-prone regions).
- Confirm water rating ≥ minimum for the wind class (N3 site → minimum 350 Pa water rating).
- Photograph each label with the slot number visible, and file with the as-built record.
- Refuse installation if any label is missing, illegible, or shows ratings below the design wind class.
Why label compliance matters:
- Insurance: home warranty insurance and PI insurance both can decline cover for windows installed without verified compliance. Post-event investigations look at labels first.
- Cyclone-zone building: in C1-C4 regions, label verification is mandatory and audited.
- Audit trail: in any dispute years later, photographs of the AS 2047 label are the contemporaneous record.
- Replacement parts: if a sash needs replacement under warranty, the label tells the supplier exactly what the unit was tested at.
Common defects:
- Label missing entirely: most common, often from low-cost imported windows or unauthorised aftermarket replacements.
- Label damaged or illegible: faded handwriting on timber, stickers peeled in transit.
- Wind class lower than required: the most expensive defect to miss; replacement is the only remedy.
- Date of manufacture stale: a window manufactured 3+ years before installation may have UV-degraded gaskets or batched non-compliant components.
- Two contradictory labels: manufacturer sticker + retailer sticker showing different ratings. Always take the lower of the two as the rating.
AGWA membership:
The Australian Glass and Window Association (AGWA) is the industry body whose member manufacturers commit to AS 2047 compliance and regular audit. The AGWA logo on a performance label is a strong signal of compliance, but it does not replace the actual ratings. Always read the wind class and water rating.
Also known as: AS 2047 label; window label; manufacturer’s performance label; AGWA label (where applicable); wind class label.
