Which Chinese Window Factory Can Meet BASIX / NatHERS Thermal Performance Requirements?

In Australia’s residential construction, BASIX and NatHERS have become two of the most important energy-efficiency assessment systems. Whether you are building in Sydney, Brisbane, or Canberra, your window and door systems must achieve strict U-value and SHGC performance levels before the project can be approved.

As a result, many Australian developers are turning to China—looking for a factory capable of delivering high-performance, cost-efficient, and standards-compliant window systems.

But the key question is:

Which Chinese factory can truly meet BASIX and NatHERS thermal performance requirements?

Surprisingly, only a small number of factories genuinely meet the standard.

Why only a few factories can meet BASIX / NatHERS?

Even though many manufacturers in China claim to produce Low-E IGU glass or thermal-break aluminium, BASIX and NatHERS require far more than materials.

To be accepted by Australian assessors, a factory must provide:

1. Verified thermal performance data

Including:

U-value

SHGC

glazing configuration

frame-to-glass ratio

tested airtightness and system performance

Verbal promises don’t count—only validated data does.

2. NatHERS-compatible assessment materials

Such as:

AFRC/WERS-recognized window values

Data packages that can be directly imported into NatHERS simulation software

Custom calculations for non-standard window shapes

Without these, assessors cannot progress your report.

3. Full-system performance—not just glass

Australia’s climate demands:

thermal-break frames

Low-E IGU glazing

multi-layer EPDM seals

structural performance for wind load and weather exposure

Only complete window systems can achieve the required energy ratings.

4. Installation and delivery capability

High-performance windows lose effectiveness if installed incorrectly.

Factories offering direct manufacturing + local Australian installation achieve the most reliable results.
