If you’re planning to build, renovate, or source aluminium windows and doors for an Australian project, you’ve probably come across the term AS2047. It is one of the most frequently referenced standards in the Australian window and door industry and plays an important role in ensuring that products are suitable for Australian conditions.

Whether you’re a homeowner, builder, architect, developer, or importer, understanding AS2047 can help you make more informed decisions when selecting windows and external doors.

This guide explains what AS2047 is, why it matters, what it covers, and how to ensure your project uses compliant products.

What Is AS2047?

AS2047 is the Australian Standard titled:

“Windows and External Glazed Doors in Buildings.”

It specifies the performance requirements for windows and external glazed doors used in residential and commercial buildings throughout Australia.

Rather than focusing on appearance or design, AS2047 establishes minimum performance criteria that products must meet under Australian environmental conditions.

The standard applies to many common products, including:

• Aluminium windows
• Aluminium sliding doors
• Hinged doors
• Bifold doors
• Awning windows
• Casement windows
• Sliding windows
• Fixed windows
• Double hung windows
• Louvre windows

Why Is AS2047 Important?

Australia experiences a wide range of environmental conditions, including:

• High wind loads
• Heavy rainfall
• Coastal exposure
• Extreme temperatures
• Cyclones in northern regions

AS2047 helps ensure that windows and doors can perform safely and reliably under these conditions.

For builders and developers, using products designed to meet AS2047 requirements helps reduce risks related to performance, durability, and compliance.

What Does AS2047 Cover?

AS2047 focuses on the overall performance of complete window and door systems.

Key performance areas include:

1. Structural Strength

Products must withstand the wind pressures specified for their intended location without excessive deformation or failure.

This is particularly important for:

• Coastal homes
• High-rise buildings
• Exposed sites
• Cyclonic regions (where applicable)

2. Water Penetration Resistance

Windows and external glazed doors must resist water entering the building during wind-driven rain conditions.

Proper testing helps ensure products remain weather-resistant in Australia’s varied climates.

3. Air Infiltration

AS2047 includes limits on unwanted air leakage through closed windows and doors.

Controlling air infiltration contributes to:

• Indoor comfort
• Energy efficiency
• Building performance

4. Operating Force

Products should open, close, and lock correctly without requiring excessive force.

This helps ensure safe and practical everyday operation.

5. Durability

Testing also considers the long-term performance of moving components such as:

• Rollers
• Hinges
• Locks
• Sliding mechanisms
• Hardware

Does AS2047 Apply to All Windows?

Most external windows and glazed doors installed in Australian buildings fall within the scope of AS2047.

However, specific applications may require additional standards depending on:

• Building type
• Location
• Fire requirements
• Bushfire zones
• Energy efficiency regulations
• Commercial façade systems

AS2047 vs AS1288

Many people confuse these two standards, but they have different purposes.

Simply put:

• AS2047 focuses on the window or door system.
• AS1288 focuses on the glass used within that system.

For most Australian projects, both standards work together.

AS2047 vs AS4284

Another common question is the difference between AS2047 and AS4284.

While both relate to building envelope performance, they are intended for different types of applications.

How Is Compliance Demonstrated?

Manufacturers typically demonstrate compliance through laboratory testing conducted on representative window or door systems.

Testing may evaluate:

• Structural performance
• Water penetration resistance
• Air infiltration
• Operational performance

Builders and specifiers should request supporting documentation from suppliers where appropriate.

How Builders Should Choose an AS2047 Window Supplier

When evaluating suppliers, don’t simply ask whether they “meet AS2047.”

Instead, consider whether the supplier can provide:

• Appropriate testing documentation
• Custom manufacturing capability
• Australian project experience
• Technical support
• Shop drawings
• Quality hardware
• Reliable delivery

A professional supplier should also understand how AS2047 fits alongside glazing requirements, architectural specifications, and project-specific performance needs.

Common Misunderstandings About AS2047

“AS2047 is only for aluminium windows.”

False.

The standard applies to many window and external glazed door systems made from different frame materials.

“If a window looks strong, it must comply.”

Appearance alone does not indicate compliance.

Products should be assessed using appropriate testing and documentation.

“AS2047 guarantees energy efficiency.”

Not exactly.

AS2047 addresses system performance, but overall energy efficiency also depends on factors such as:

• Glass selection
• Frame design
• Building orientation
• Insulation
• Local building regulations

“Every window has the same performance.”

Different window systems may achieve different performance ratings depending on their design, configuration, size, and intended application.

Why AS2047 Matters for Imported Windows

Australia imports many aluminium windows and doors from overseas manufacturers.

Before purchasing imported products, builders and developers should confirm that the selected systems are suitable for Australian projects and supported with appropriate testing and technical documentation.

Choosing a supplier experienced in Australian standards can help avoid delays, redesigns, or compliance issues during construction.

Conclusion

AS2047 is one of the most important standards in Australia’s window and door industry. It establishes performance requirements for windows and external glazed doors, helping ensure they can withstand Australian weather conditions while operating safely and reliably.

Whether you’re building a custom home, a multi-residential development, or a commercial project, understanding AS2047 makes it easier to select products that are appropriate for your project’s performance requirements.

Working with an experienced supplier that understands Australian standards, provides technical documentation, and offers project support is one of the best ways to ensure a successful outcome.

Frequently Asked Questions

What is AS2047?

AS2047 is the Australian Standard that specifies performance requirements for windows and external glazed doors used in buildings.

Why is AS2047 important?

It helps ensure windows and doors can perform under Australian conditions, including wind, rain, and everyday operation.

Does AS2047 apply to aluminium windows?

Yes. Most aluminium windows and external glazed doors supplied for Australian projects are designed with AS2047 requirements in mind.

What is the difference between AS2047 and AS1288?
