Choosing the right windows is an essential aspect of any construction or renovation project. Windows not only serve as a source of natural light and ventilation but also contribute to the aesthetic appeal and energy efficiency of a building. Among the various materials available, aluminium windows have gained popularity for their durability and modern look. As a glazier with over 30 years of experience installing windows in Australia, I bring a wealth of knowledge to help you make an informed decision.

What are Aluminium Windows?

Aluminium windows are window frames constructed using aluminium, a lightweight yet strong metal. These windows are known for their slim profile, allowing for a larger glass surface area and a sleek modern aesthetic. In Australia, aluminium windows became popular in the mid-20th century as an alternative to traditional timber windows. They are versatile and can be used in residential homes, commercial buildings, and industrial settings.

Advantages of Aluminium Windows


Durability and Longevity

Aluminium is resistant to corrosion, warping, and rusting, which makes it an excellent material for windows, especially in areas with harsh weather conditions. Additionally, aluminium windows require low maintenance.

Design Flexibility

Aluminium can be easily molded into various shapes, and its frames come in a range of finishes and colors. This makes it suitable for both modern and traditional building designs.

Energy Efficiency

With the right glazing, aluminium windows can have excellent thermal performance, helping to keep the heat in during winter and out during summer.


The strength of aluminium frames combined with proper locking mechanisms makes these windows highly secure.

Expert Insight

In my 30 years of experience, I have observed that clients who opt for aluminium windows appreciate their durability and the modern touch they add to the building.

Disadvantages of Aluminium Windows

Initial Costs

Aluminium windows can be more expensive upfront compared to other materials like uPVC. However, their durability can make them more cost-effective in the long run.

Potential for Condensation

Aluminium windows can sometimes suffer from condensation, which can be mitigated with proper insulation.

Thermal Conductivity

Aluminium is a good conductor of heat, which can be a disadvantage in terms of thermal insulation. However, modern aluminium windows come with thermal breaks that significantly improve insulation.

Expert Insight

Some clients have initially been hesitant about the cost of aluminium windows but found the investment worthwhile due to the long-term benefits.

Breakdown of Costs

The costs of aluminium windows include material costs, installation, and maintenance. While material and installation are one-time costs, maintenance is ongoing, though minimal for aluminium.

Return on Investment

The energy savings and increased property value due to aluminium windows can contribute to a positive return on investment.

Cost Comparison with Other Window Types

While more expensive than uPVC, aluminium windows are often cheaper than timber windows.

Expert Tips for Cost-Efficiency

Choosing double glazing and thermal breaks can increase the cost-efficiency of aluminium windows.

Considerations for Choosing Aluminium Windows

When choosing aluminium windows, consider the local climate, the architectural style of the building, and your budget. In Australia, it’s also important to consider bushfire regulations, as aluminium windows with special glazing can be used in bushfire-prone areas.
