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.
