AS2047 is the Australian Standard that specifies the performance requirements for external windows and glazed doors used in residential and commercial buildings. It evaluates factors such as structural strength, air infiltration, water penetration resistance and wind resistance. Selecting window systems tested to AS2047 helps builders and homeowners meet project specifications and achieve reliable long-term performance.

Introduction

Choosing aluminium windows is about much more than appearance. In Australia, windows must perform reliably under a wide range of environmental conditions, including strong winds, heavy rainfall, high UV exposure and changing temperatures.

To help ensure this performance, Australia has established recognised standards for windows and glazed doors. One of the most important is AS2047, which sets out performance requirements for external windows and glazed doors used in Australian buildings.

Whether you are building a new home, renovating an existing property or managing a commercial project, understanding AS2047 can help you make informed decisions when selecting aluminium window systems.

What Is AS2047?

AS2047 is the Australian Standard that defines the minimum performance requirements for external windows and glazed doors.

Rather than prescribing a specific window design, the standard focuses on how a completed window system performs when tested under controlled conditions.

Manufacturers typically submit representative products for laboratory testing to verify performance against the standard’s requirements.

What Does AS2047 Test?

AS2047 evaluates several critical performance areas that influence how windows perform in real-world conditions.

1. Structural Performance

Windows must withstand design wind loads without permanent deformation or failure.

This is particularly important in regions exposed to strong winds, cyclones or elevated building heights.

2. Water Penetration Resistance

One of the most recognised parts of AS2047 is water penetration testing.

Windows are tested under simulated wind-driven rain conditions to evaluate whether water enters the building.

Proper drainage design, seals and frame construction all contribute to this performance.

3. Air Infiltration

Air leakage affects:

• Indoor comfort
• Energy efficiency
• Heating and cooling costs

AS2047 includes testing that measures the amount of air passing through a closed window under specified pressure differences.

4. Operating Force

The standard also considers usability.

Windows should open, close and lock without excessive force while maintaining secure operation.

Why Is AS2047 Important?

AS2047 provides a consistent benchmark for evaluating the performance of external windows and glazed doors.

For different stakeholders, its value includes:

Homeowners

• Greater confidence in product performance
• Better resistance to weather
• Improved comfort and durability

Builders

• Products that meet project specifications
• Performance documentation for compliance
• Consistent quality expectations

Architects

• Reliable performance data for product selection
• Confidence when specifying window systems

Developers

• Reduced project risk
• Consistency across multiple installations

Does AS2047 Guarantee Quality?

Meeting AS2047 demonstrates that a tested product has achieved the required performance levels under laboratory conditions.

However, overall performance also depends on:

• Correct product selection
• Appropriate glass specification
• Professional installation
• Ongoing maintenance

A compliant product should always be installed according to the manufacturer’s instructions and applicable building requirements.

AS2047 and Different Australian Climate Zones

Australia includes a wide range of climate conditions, from tropical regions to temperate coastal areas and inland environments.

When selecting aluminium windows, factors such as:

• Wind exposure
• Rainfall
• Building height
• Site location

should all be considered alongside the project’s design requirements.

AS2047 testing helps demonstrate how a window system performs under these types of conditions.

AS2047 and Aluminium Windows

Aluminium has become one of the most commonly used framing materials in Australia because it offers:

• High strength-to-weight ratio
• Corrosion resistance
• Low maintenance
• Compatibility with large glass panels
• Design flexibility

When aluminium window systems are designed, manufactured and tested to AS2047 requirements, they can provide reliable performance for a wide range of residential and commercial applications.

Choosing AS2047-Compliant Aluminium Windows

When evaluating aluminium windows, ask suppliers for documentation such as:

• Performance test reports
• Product specifications
• Glass information
• Installation guidance
• Compliance documentation (where applicable)

Reviewing this information helps ensure the selected window system is appropriate for your project’s requirements.
