Aluminium Window Frames: A Modern Option
Aluminium window frames are one of the most popular choices for homeowners in Australia regarding single or double-glazed window frames. Known for their sleek, contemporary appearance and strength, aluminium windows offer several key advantages:
Advantages of Aluminium Windows
- Durability and Strength: Aluminium is a highly durable material resistant to corrosion and rust. It can withstand harsh weather conditions, making it ideal for coastal areas with salty air. When paired with double glazing, aluminium window frames offer superior insulation properties.
- Low Maintenance: Aluminium is very low maintenance compared to timber. It doesn’t require regular sanding, painting, or treatment to maintain appearance.
- Energy Efficiency: Double-glazed aluminium windows provide excellent thermal insulation. The gap between the two panes helps to reduce heat transfer, keeping your home cooler in summer and warmer in winter.
- Sleek, Modern Look: Aluminium frames are slim and strong, allowing for larger windows and more glass area. This is ideal for homeowners who want maximum natural light and unobstructed views.
Disadvantages of Aluminium Windows
- Higher Initial Cost: While aluminium is generally more affordable than timber, it can be more expensive than uPVC, depending on the design and glazing options chosen.
- Thermal Conductivity: Aluminium is a good conductor of heat. However, this can be mitigated with thermal breaks in modern aluminium window frames that improve insulation.

uPVC Window Frames: Affordable and Energy Efficient
uPVC (unplasticised polyvinyl chloride) window frames have become increasingly popular in Australia due to their energy efficiency and affordability. This material is commonly used for uPVC windows, which are well-suited to the Australian climate.
Advantages of uPVC Windows
- Energy Efficiency: uPVC window frames are naturally good insulators. They offer superior energy efficiency compared to aluminium because the material is a poor heat conductor. This makes double glazed uPVC windows an excellent choice for those looking to reduce energy bills and maintain a comfortable indoor environment.
- Low Maintenance: Like aluminium, uPVC window frames require very little upkeep. The material does not warp, corrode, or need regular repainting.
- Affordability: uPVC windows are typically more affordable than aluminium and timber frames, making them a popular choice for budget-conscious homeowners.
- Weather Resistance: uPVC is resistant to the elements, particularly the harsh Australian sun, and will not fade or discolour over time.

Disadvantages of uPVC Windows
- Less Aesthetic Flexibility: While uPVC window frames are available in a variety of colours, they may not offer the same traditional, elegant look that timber frames provide. If you’re seeking a more classic or rustic design, timber may be the better choice.
- Susceptibility to Damage: Though uPVC is resistant to most weather conditions, it can be damaged by extreme impacts or scratches, which may affect its appearance over time.
uPVC vs Aluminium Windows
While uPVC vs aluminium windows often comes down to personal preference, uPVC windows are typically more energy-efficient and cost-effective, while aluminium windows tend to be more durable and visually appealing.

Timber Window Frames: Classic and Timeless
Although not available at Perth Window and Door Replacement Company, timber window frames are still a popular option for homeowners seeking a traditional, rustic aesthetic. Timber windows bring warmth and character to a home, especially in heritage or period-style properties.
Advantages of Timber Windows
- Aesthetic Appeal: Timber window frames offer a natural, classic look that synthetic materials cannot replicate. Timber is ideal for achieving a rustic, traditional style.
- Insulation: Double glazed timber windows offer good insulation properties, though not as high as uPVC or aluminium when paired with double glazing. The natural wood helps to maintain indoor temperatures.
- Customisable: Timber is easy to customise and can be painted or stained in any colour to suit the look of your home.
Disadvantages of Timber Windows
- High Maintenance: Timber windows require regular maintenance, including painting, staining, and treating for rot or insect damage. Without proper care, timber windows can deteriorate over time.
- Vulnerability to Weathering: Timber is susceptible to swelling, warping, or rotting when exposed to moisture, making it less suitable for coastal or high-humidity areas compared to aluminium or uPVC.
- Higher Cost: Timber window frames are typically more expensive than both aluminium and uPVC, both in terms of material cost and maintenance.
Durability and Maintenance Considerations
Comparing Material Longevity and Upkeep
When it comes to durability and maintenance, each window material has its unique characteristics. Timber windows require regular maintenance to prevent warping and rotting. They need to be painted or varnished periodically to maintain their appearance and protect them from the elements. On the other hand, aluminium windows are known for their low maintenance requirements. They are resistant to corrosion and can withstand harsh weather conditions, though they may require only occasional cleaning to maintain their sleek look.
Similarly, uPVC windows are also low maintenance and can withstand harsh weather conditions. They are resistant to rotting and warping, requiring only occasional cleaning to keep them looking their best.
In terms of longevity, timber windows can last for many years if properly maintained, often up to 30 years or more. Aluminium windows can last up to 40 years, while uPVC windows can last up to 25 years. Double glazed windows, regardless of the material, can last longer than single glazed windows due to the added insulation and protection from the elements. This makes double glazing a worthwhile investment for any window material, enhancing both durability and energy efficiency.
Sustainability and Environmental Impact
Eco-Friendliness of Window Materials
When it comes to sustainability and environmental impact, each window material has its unique characteristics. Timber windows are a natural, renewable resource, and when sourced from sustainable suppliers, they can be an eco-friendly option. However, the production process and transportation of timber windows can have a significant environmental impact.
Aluminium windows are made from a non-renewable resource, but they can be recycled at the end of their life cycle, making them a more sustainable choice in the long run. uPVC windows are made from a non-renewable resource and are not biodegradable. However, they can be recycled, and some manufacturers offer recycling programs to reduce their environmental footprint.
Double glazed windows, regardless of the material, can help reduce energy consumption and greenhouse gas emissions by providing better insulation and reducing heat transfer. Thermally broken aluminium frames can also improve energy efficiency by reducing heat transfer, making them an excellent choice for environmentally conscious homeowners. By choosing double glazing and thermally broken frames, you can enhance the sustainability of your windows and contribute to a greener home.

Aesthetic and Design Options
Customising Your Window Style
When it comes to aesthetic and design options, each window material offers unique characteristics. Timber windows can be stained or painted to match many architectural styles, from traditional to modern, offering a high degree of customisation. Aluminium windows can be powder-coated or anodised to provide a durable and low-maintenance finish, perfect for a sleek, modern appearance – view our colour range here. uPVC windows can be customised with a number of colours and finishes to match various architectural styles, providing a versatile and low-maintenance option.
Popular window styles such as casement windows, double hung windows, and awning windows can be made from any of the three materials, allowing you to choose the best fit for your home. Louvre windows and bi-fold windows are also popular styles that can be made from aluminium or uPVC, offering modern and functional design options. Custom windows can be designed to fit any shape or size, providing endless design possibilities.
In terms of design flexibility, timber windows offer the most options, as they can be shaped, painted, and varnished to match any design style. Aluminium windows offer a sleek, modern design, while uPVC windows offer a versatile and low-maintenance option. Whether you prefer the classic charm of timber, the modern appeal of aluminium, or the practicality of uPVC, there are plenty of design options to suit your taste and home style.
