How Aluminium Windows Are Tested Under AS 2047: Complete Testing Guide

Quick Answer

AS 2047 is the Australian Standard that specifies performance requirements for external windows and glazed doors. Testing evaluates important factors including structural strength, water penetration resistance, air infiltration, operating forces and overall performance. These tests help verify whether a window system is suitable for Australian building applications.

Introduction

Aluminium windows are a critical part of the building envelope.

They must perform under a wide range of Australian conditions, including:

• Strong winds
• Heavy rainfall
• Coastal environments
• Temperature changes
• Daily operation

For this reason, professional window systems are tested against recognised performance requirements.

In Australia, AS 2047 – Windows and external glazed doors in buildings is one of the key standards used when evaluating window performance.

At MEICHEN Windows & Doors, we design and manufacture aluminium window and door systems for Australian residential and architectural projects, with a focus on performance, quality control and compliance requirements.

What Is AS 2047?

AS 2047 is an Australian Standard covering performance requirements for external windows and glazed doors used in buildings.

It addresses key performance areas, including:

• Structural performance
• Resistance to water penetration
• Air infiltration
• Operating forces
• Safety-related considerations

The purpose of AS 2047 testing is to confirm that window systems are suitable for their intended application.

Why AS 2047 Testing Matters

Australian buildings experience different environmental conditions depending on:

• Location
• Wind exposure
• Climate
• Building height
• Surrounding terrain

A window system designed for a sheltered suburban home may not be suitable for:

• Coastal properties
• High-rise applications
• Large architectural glazing
• High wind areas

Testing helps ensure the selected system matches project requirements.

The AS 2047 Testing Process

AS 2047 performance evaluation typically involves several key tests.

1. Air Infiltration Testing

Air infiltration testing measures how much air passes through a closed window system under controlled pressure conditions.

This evaluates:

• Sealing effectiveness
• Frame design
• Gasket performance
• Manufacturing quality

Good air control contributes to:

• Indoor comfort
• Energy efficiency
• Reduced unwanted drafts

2. Water Penetration Testing

Water penetration testing evaluates the ability of a window system to resist water entry during simulated weather conditions.

The test commonly involves:

• Applying water spray
• Applying controlled air pressure
• Observing potential water entry points

This helps assess:

• Frame design
• Drainage systems
• Weather seals
• Installation interfaces

3. Structural Strength Testing

Structural testing evaluates how the window system performs under applied loads.

This considers:

• Aluminium profile strength
• Glass performance
• Hardware capability
• Frame connections

The purpose is to confirm that the window can withstand expected service conditions.

4. Deflection Testing

Deflection testing examines how much components move when subjected to pressure.

Excessive movement may affect:

• Operation
• Sealing performance
• Long-term durability

Window systems must maintain acceptable performance under design loads.

5. Operating Force Testing

Windows and doors should operate correctly after testing.

Operating force testing evaluates:

• Opening effort
• Closing performance
• Hardware function

A high-performance window should not only resist weather conditions but also remain practical to use.

AS 2047 and Wind Performance

Wind performance is one of the most important considerations for Australian windows.

The required performance depends on:

• Site location
• Wind region
• Terrain category
• Building height
• Exposure conditions

Engineers may use structural design calculations to determine the required window performance level.

AS 2047 and Aluminium Profile Design

The aluminium frame is a major factor affecting window performance.

Important design elements include:

• Profile geometry
• Material thickness
• Reinforcement requirements
• Corner connections
• Drainage design

A professionally engineered aluminium system balances:

• Strength
• Weight
• Appearance
• Manufacturing efficiency

AS 2047 and Glass Selection

Glass selection must match the overall window requirements.

Factors include:

• Panel size
• Wind pressure
• Safety requirements
• Thermal objectives

Common options include:

Toughened Safety Glass

Used where impact resistance and safety performance are required.

Laminated Glass

Often selected for:

• Safety
• Acoustic performance
• Security considerations

Double Glazing

Provides:

• Improved thermal performance
• Better comfort
• Reduced heat transfer

Low-E Glass

Helps control heat transfer and solar performance.

AS 2047 vs AS 1288

These standards address different aspects of window performance.

AS 2047

Focuses on:

• Window and door performance
• Structural capability
• Weather resistance

AS 1288

Focuses on:

• Glass selection
• Safety glazing
• Installation requirements

Both may apply to an Australian window project.

AS 2047 and NCC Requirements

The National Construction Code references performance requirements that affect building components, including windows.

Window selection should consider:

• Structural requirements
• Weatherproofing
• Energy efficiency
• Safety

Compliance should always be considered as part of the complete building design.

Common Mistakes When Selecting AS 2047 Windows

Mistake 1: Assuming All Aluminium Windows Are Equivalent

Different systems may have different:

• Profile designs
• Testing results
• Performance capabilities

Mistake 2: Looking Only at Certification Labels

Performance depends on matching the tested system to the actual project requirements.

Mistake 3: Ignoring Installation

Even tested windows require correct installation to perform properly.

Mistake 4: Choosing Based Only on Appearance

Slim frames and large glass areas must still meet structural and weather requirements.

Selecting an AS 2047 Window Manufacturer

When choosing a supplier, consider:

• Testing documentation
• Manufacturing capability
• Quality control
• Technical support
• Project experience

A reliable manufacturer should be able to provide clear technical information.
