Yes, AS2047 is an important Australian Standard for external windows and glazed doors, and many Australian building projects require window systems to meet AS2047 performance requirements. However, the exact requirements depend on the building type, location, project specifications and applicable building regulations.

AS2047 itself is a performance standard rather than a standalone law. In practice, builders, architects, manufacturers and certifiers use AS2047 requirements to demonstrate that external windows and doors are suitable for their intended application.

Introduction

When building or renovating a property in Australia, one of the most common questions about windows is:

“Do my windows need to be AS2047 certified?”

The short answer is that AS2047 plays an important role in Australian construction, especially for external windows and glazed doors.

However, understanding AS2047 compliance requires looking at how Australian building requirements work.

AS2047 does not simply mean a product has a label saying “approved”. Instead, it relates to whether a window or door system has been designed and tested to achieve required performance levels.

What Is AS2047?

AS2047 is the Australian Standard for the performance of external windows and glazed doors.

It evaluates whether a window system can perform under expected conditions, including:

• Wind pressure
• Water penetration
• Air infiltration
• Operating performance

The standard applies to many external window and door products used in Australian buildings.

Examples include:

• Aluminium awning windows
• Aluminium sliding windows
• Fixed windows
• Casement windows
• Sliding doors
• Bifold doors

Is AS2047 Legally Mandatory?

This is one of the most misunderstood topics.

The answer depends on how the standard is referenced within Australian building requirements and project specifications.

In many construction projects, compliance with relevant Australian Standards is required to demonstrate that products meet acceptable performance requirements.

However:

• Not every product is identical.
• Requirements may vary depending on location and building type.
• Specific project documentation should always be checked.

For builders and developers, AS2047 compliance is often an essential consideration when selecting external windows and doors.

Why Do Australian Builders Require AS2047 Windows?

Builders typically consider AS2047 because windows are part of the building envelope.

Poor-performing windows can contribute to:

• Water leakage
• Air leakage
• Reduced comfort
• Maintenance issues
• Project delays

AS2047 testing provides confidence that the window system has been evaluated under controlled conditions.

What Happens If Windows Do Not Meet AS2047 Requirements?

Using unsuitable window systems can create several risks.

1. Building Approval Issues

Building surveyors, certifiers or project managers may request documentation showing that products meet required performance specifications.

2. Weather Performance Problems

Windows without suitable performance testing may have increased risk of:

• Water penetration
• Air leakage
• Poor sealing performance

3. Replacement Costs

If windows fail to meet project requirements after installation, replacement or repair can become expensive.

When Is AS2047 Especially Important?

AS2047 consideration is particularly important for:

1. Coastal Properties

Coastal areas may experience:

• Strong winds
• Salt exposure
• Heavy weather conditions

Window systems need suitable durability and weather performance.

Examples:

• Sydney coastal homes
• Gold Coast properties
• Perth coastal developments

2. Large Architectural Windows

Modern homes increasingly use:

• Floor-to-ceiling glass
• Large sliding doors
• Slim frame windows

Larger glass areas require careful consideration of:

• Structural performance
• Glass selection
• Frame strength

3. Multi-Storey Buildings

Higher buildings may experience increased wind pressure.

Window performance requirements become more important as building height increases.

4. High Wind Areas

Some Australian regions have higher wind exposure.

Projects may require window systems designed for specific wind loads.

What Does AS2047 Compliance Mean for Aluminium Windows?

For aluminium windows, AS2047 compliance generally relates to the performance of the complete window system.

This includes:

Aluminium Frame

The frame must provide suitable structural strength.

Hardware

Components such as:

• Locks
• Hinges
• Rollers

must support reliable operation.

Weather Seals

Sealing systems help control:

• Water entry
• Air infiltration

Drainage Design

Modern aluminium windows use drainage systems to manage water movement.

AS2047 Compliance vs Certification: What’s the Difference?

Another common question is:

“Does AS2047 mean every window has a certificate?”

Not necessarily.

There is a difference between:

Product Testing

A representative window or door system is tested under controlled conditions.

Compliance Documentation

Manufacturers provide technical information showing product performance.

Project Requirements

Specific projects may require particular documentation depending on:

• Location
• Building type
• Design requirements

How Can Builders Check AS2047 Compliance?

Before selecting aluminium windows, builders should request:

1. Performance Documentation

Including:

• Test reports
• Product specifications
• Performance ratings

2. Product Details

Confirm:

• Window type
• Size limitations
• Glass specification
• Installation requirements

3. Supplier Experience

Choose suppliers familiar with:

• Australian projects
• Local requirements
• Technical documentation

Does AS2047 Apply to Glass?

No.

AS2047 focuses on the performance of the complete window or external glazed door system.

Glass selection and safety requirements are mainly covered by:

AS1288 – Glass in Buildings: Selection and Installation

The two standards work together.

Frequently Asked Questions

Are AS2047 windows mandatory in Australia?

AS2047 is an important performance standard for external windows and glazed doors, and many Australian construction projects require products to meet its requirements.

Do all windows need AS2047 certification?

Requirements depend on the project, building type and applicable regulations. External windows and doors commonly need to demonstrate suitable performance.

Is AS2047 a law?

AS2047 is an Australian Standard. Whether it is mandatory depends on how it is referenced in building requirements and project specifications.

How do I know if a window meets AS2047?

Ask the supplier for relevant performance documentation, test reports and product specifications.

Why is AS2047 important for builders?

It helps demonstrate that external window systems can perform against wind, water and air infiltration requirements.
