Aluminium Vs. uPVC Windows: Which Ones Are Better?

When it comes to choosing windows for your home, two popular options often come to mind: aluminium and uPVC. Both materials have their own set of advantages and disadvantages, making the decision a bit challenging.

Let’s delve into the specifics of each to help you make an informed choice.

Aluminium Windows

Strength and Elegance

Aluminium is known for its strength and lightweight nature. Its thin sections can elegantly support large glass panes, increasing the glass surface area and allowing more light to filter into your interiors. This makes aluminium windows a great option for those looking to create a bright and airy atmosphere in their home.

Durability

Aluminium windows are highly durable. They are resistant to rust and can withstand various weather conditions without swelling or cracking. However, they may not be the best choice for coastal areas due to potential corrosion from salt-laden air. In suitable conditions, aluminium windows can last more than 45 years.

Variety of Finishes

Aluminium windows come in various styles such as casement, sliding, and tilt-and-turn windows. They can be finished with durable powder coating or anodising, offering a wide range of colours and finishes like satin, gloss, or matte. This allows homeowners to match their windows with their overall decor seamlessly.

Eco-Friendly

One of the significant benefits of aluminium is its recyclability. Aluminium is 100% recyclable, making it an environmentally friendly choice for sustainable building.

Insulation Challenges

A major drawback of aluminium windows is their poor insulation properties. Being a good conductor of heat, aluminium can lead to heat gain or loss in a building. However, this issue can be mitigated by incorporating a thermal break – a rubber or vinyl strip that prevents heat transfer through the metal.

Maintenance Needs

While aluminium is durable, it requires periodic maintenance. High winds can cause aluminium windows to rattle, potentially loosening screws. Additionally, they may need a fresh coat of paint after a few years to maintain their appearance.

uPVC Windows

Robust and Weather-Resistant

uPVC is a strong and durable material resistant to UV rays, rust, and corrosion, making it ideal for coastal areas. uPVC windows are reinforced with galvanised steel sections, enhancing their strength and durability.

Enhanced Security

uPVC windows can be equipped with multiple-lock systems and shootbolt locks, providing enhanced security for your home. This makes them a reliable option for homeowners concerned about safety.

Low Maintenance

uPVC windows are easy to maintain with simple cleaning routines. A quick wipe with a damp cloth or a light soapy solution is usually enough to keep them looking new. They also feature a built-in rain track with a slope, preventing water from seeping indoors.

Superior Insulation

uPVC windows offer excellent thermal insulation. They are poor conductors of heat, preventing heat loss or gain and making your home more energy-efficient. This is a significant advantage over aluminium windows, especially in extreme climates.

Noise Reduction

Double- or triple-glazed uPVC windows are effective at soundproofing, making them ideal for homes near busy roads. They act as acoustic barriers, significantly reducing outdoor noise.

Shorter Lifespan

One downside of uPVC is its shorter lifespan, typically around 25 to 30 years. Some homeowners also find the plastic look of uPVC less attractive compared to the sleek appearance of aluminium.

Our Take 

Choosing between aluminium and uPVC windows depends on your specific needs and preferences. Aluminium windows offer strength, durability, and a sleek appearance, making them suitable for modern homes. However, they require periodic maintenance and provide less insulation. On the other hand, uPVC windows offer excellent insulation, low maintenance, and enhanced security, making them ideal for energy-efficient homes, although they have a shorter lifespan and a plastic look.

Ultimately, the choice comes down to what matters most to you: durability and sleek design or insulation and low maintenance. For more home design tips and insights, visit the Homebliss blog and transform your living space with expert advice!
