Double Glazed Aluminium Windows Australia: Benefits, Costs and Performance Guide

Quick Answer

Double glazed aluminium windows use two glass panes separated by an insulating cavity to improve thermal and acoustic performance. In Australia, they are increasingly popular because they can help improve indoor comfort, reduce heat transfer and support energy-efficient home design. Performance depends on the complete window system, including glass type, aluminium frame design, seals and installation quality.

Energy efficiency has become an important consideration for Australian homeowners, builders and architects.

Windows are a major part of the building envelope and directly influence:

• Indoor temperature
• Heating and cooling demand
• Acoustic comfort
• Natural light
• Overall home performance

Traditional single glazing may allow significant heat transfer, especially in Australia’s varied climates.

As a result, many modern residential projects are choosing:

Double glazed aluminium windows

to achieve better comfort and performance.

At MEICHEN Windows & Doors, we manufacture aluminium window and door systems for Australian residential and architectural applications, offering glazing solutions designed around project requirements.

Double glazing consists of two glass panels separated by an insulating cavity.

A typical double glazed unit includes:

• Outer glass pane
• Spacer bar
• Insulating cavity
• Inner glass pane
• Sealing system

When combined with an aluminium frame, the complete system creates a high-performance window solution.

The insulating cavity between the glass layers reduces direct heat transfer.

Compared with single glazing, double glazing can help reduce:

• Heat entering during summer
• Heat escaping during winter
• External noise transmission

The final performance depends on:

• Glass type
• Cavity design
• Frame system
• Installation quality

One of the main advantages of double glazing is improved temperature control.

Benefits may include:

• More stable indoor temperatures
• Reduced hot and cold areas near windows
• Improved comfort throughout the year

Windows influence heating and cooling requirements.

High-performance glazing may help:

• Reduce unwanted heat gain
• Reduce heat loss
• Improve overall building efficiency

However, energy performance depends on the complete home design, including:

• Orientation
• Insulation
• Shading
• Ventilation

Double glazing can help reduce external noise.

This can be beneficial for homes located near:

• Busy roads
• Urban areas
• Airports
• Commercial zones

Acoustic performance depends on:

• Glass thickness
• Glass combination
• Air cavity
• Installation quality

Better insulating performance can help reduce temperature differences between indoor and outdoor surfaces.

However, condensation also depends on:

• Indoor humidity
• Ventilation
• Climate
• Building design

Modern buyers increasingly consider:

• Energy efficiency
• Comfort
• Noise control
• Quality finishes

High-performance windows can contribute to the overall appeal of a property.

Aluminium is one of Australia’s most popular window materials because of its:

• Strength
• Durability
• Slim appearance
• Low maintenance

However, aluminium naturally conducts heat.

For higher thermal performance projects, options may include:

• Thermal break aluminium frames
• Improved glazing systems
• Low-E glass

The complete window system determines the final performance.

Low-E means:

Low Emissivity Glass

It uses a specialised coating designed to control radiant heat transfer.

Depending on the application, Low-E glass may help:

• Reduce heat loss
• Control solar heat gain
• Improve comfort

Low-E glass is commonly combined with:

• Double glazing
• Safety glass
• Aluminium window systems

Australia has many different climate conditions.

The ideal glazing specification depends on location.

Priorities may include:

• Solar heat control
• Lower SHGC
• Ventilation

May require balance between:

• Summer cooling
• Winter warmth

May prioritise:

• Heat retention
• Lower U-Value

NCC 2022 places increased focus on residential energy efficiency.

Window performance may consider:

• U-Value
• SHGC
• Glazing selection
• Frame performance

Double glazing may assist projects targeting improved energy performance, depending on the overall design.

WERS evaluates complete window system performance.

Factors include:

• Glass
• Frame
• Configuration

Double glazing can contribute to improved performance, but the final rating depends on the entire window system.

The cost of double glazed aluminium windows depends on:

Window Size

Larger windows generally require:

• More materials
• Larger glass panels
• Stronger engineering

Glass Specification

Costs vary depending on:

• Glass thickness
• Low-E coatings
• Safety requirements
• Acoustic requirements

Frame System

Factors include:

• Standard aluminium
• Thermal break aluminium
• Slim architectural systems

Hardware

Quality hardware affects:

• Operation
• Durability
• Long-term performance

Mistake 1: Choosing Glass Without Considering the Frame

The glass is only one part of the window system.

Mistake 2: Assuming Double Glazing Solves All Energy Issues

Window performance depends on:

• Building design
• Orientation
• Installation
• Shading

Mistake 3: Ignoring Installation Quality

Incorrect installation can reduce expected performance.

Mistake 4: Selecting Based Only on Price

A lower initial cost may not provide the best long-term value.

Common applications include:

• New homes
• Luxury residences
• Renovations
• Architectural projects
• Energy-efficient homes

Popular product types include:

• Double glazed sliding windows
• Double glazed awning windows
• Double glazed casement windows
• Double glazed sliding doors
