In Australia, sunrooms have become a popular way to expand living space and bring natural light into the home. But behind those elegant glass walls lies a serious engineering challenge — ensuring performance under Australia’s demanding climate conditions.
To guarantee comfort, safety, and energy efficiency throughout the year, all sunroom windows and doors must comply with the AS2047 standard.
What Is AS2047?
AS2047 stands for Windows and External Glazed Doors in Buildings, issued by Standards Australia.
It is the mandatory performance certification for all windows and doors installed in Australian buildings.
The certification involves four main tests:
Water Penetration Resistance – Prevents leaks during heavy rain and wind, crucial for large glass areas in sunrooms.
Air Infiltration – Ensures airtight sealing to reduce heat loss and improve energy efficiency.
Wind Pressure Resistance – Verifies structural strength against strong coastal or high-rise winds.
Operating Force – Confirms that sliding and hinged systems operate smoothly and remain durable over time.
Why AS2047 Is Essential for Sunrooms
Unlike standard windows, sunrooms feature large glass walls and narrow aluminium frames, which face more exposure to sunlight, temperature changes, and wind pressure.
Without AS2047 certification, problems can include:
Water leaks during storms
Frame distortion or seal failure
Overheating in summer or heat loss in winter
Failure to meet BASIX or NatHERS energy ratings
In contrast, AS2047-certified systems offer:
✅ Reliable waterproof and airtight performance
✅ Strong structural safety under high wind load
✅ Better insulation and energy efficiency
✅ Full compliance with Australian building codes (BCA/NCC)
