An Insight into Aluminium Windows

What are aluminium windows? In simple terms, aluminium windows are windows made from aluminium, a strong yet lightweight metal. The popularity of aluminium windows has grown considerably, with aluminium windows now found in both commercial and residential buildings, thanks to their sleek design and reliable performance.

Aluminium windows owe their strength to aluminium. This strength paves the way for slim frames in aluminium windows, presenting a modern, minimalist appeal while ensuring maximum penetration of light. Moreover, aluminium windows offer the versatility to match any architectural style, with an extensive range of finishes to select from for your aluminium windows.

Further to this, aluminium windows promise durability. Aluminium windows have impressive resistance to elements like rust, corrosion, and warping. This longevity means that aluminium windows not only offer great value for money but also stand up to extreme weather conditions, making aluminium windows a crucial factor if you’re located in an area with a harsh climate.

Why Aluminium Windows Stand Out

Aluminium windows offer a plethora of benefits. One major advantage of aluminium windows is the potential for larger glass expanses, thanks to the strength of aluminium. This allows aluminium windows to offer breathtaking, uninterrupted views – a dream for homes overlooking scenic landscapes.

Furthermore, aluminium windows champion durability. The metal in these aluminium windows can withstand the test of time, maintaining their look and functionality for decades with minimal maintenance. This means aluminium windows are tougher to breach than most other materials, offering secure homes.

And let’s not forget about the sustainability aspect of aluminium windows. Aluminium is fully recyclable and retains its properties even after recycling, making aluminium windows a green choice in the long run.

uPVC Windows Explained

Switching gears, let’s discuss uPVC windows. uPVC stands for Unplasticised Polyvinyl Chloride. uPVC windows have been a go-to option for homeowners for many years, thanks to their perfect blend of affordability and functionality.

uPVC windows are renowned for their excellent thermal performance. uPVC windows incorporate multiple chambers within their frames. These chambers in uPVC windows act as a barrier, trapping heat and keeping the cold at bay. This design in uPVC windows contributes to energy conservation, leading to reduced heating bills.

Advantages of uPVC Windows

uPVC windows have a lot to offer. The affordability of uPVC windows is perhaps the most significant pull factor. With generally lower prices than aluminium windows, uPVC windows are an attractive option for those on a budget.

uPVC windows also offer superior thermal efficiency. The multi-chambered design of uPVC window frames acts as a formidable insulator, helping to maintain comfortable temperatures in your home year-round.

When it comes to durability, uPVC windows don’t disappoint. uPVC windows resist corrosion, rot, and warping, maintaining their appearance for many years. uPVC windows are also available in a variety of colours and finishes, making uPVC windows a versatile choice for any home style.


Aluminium and uPVC Windows: What are the Differences?

Aesthetics and Design

Aluminium windows are known for their sleek, modern appeal. The robustness of aluminium allows for slim, minimalistic frames in aluminium windows that can accommodate larger panes of glass. This results in more natural light entering your home through aluminium windows, offering uninterrupted views. In addition, aluminium windows are available in a wide range of finishes, allowing for considerable customisation to match the architectural style of any home or commercial building.

uPVC windows, on the other hand, tend to have thicker frames due to the material’s lesser strength compared to aluminium windows. However, advancements in uPVC technology have resulted in slimmer profiles becoming available in uPVC windows. While uPVC windows may not offer the same ‘industrial chic’ as aluminium windows, they can still provide a clean, modern look. The range of colours and finishes in uPVC windows is generally more limited than in aluminium windows, but there are enough options in uPVC windows to suit most home styles.

Durability and Maintenance

In terms of durability, aluminium windows take the lead. Aluminium windows are resistant to rust, corrosion, and warping, capable of withstanding harsh weather conditions, and have an impressive lifespan that can extend up to several decades with minimal maintenance. This makes aluminium windows a reliable long-term investment.

uPVC windows also offer commendable durability. uPVC windows are resistant to rot and corrosion, and the colour of uPVC windows doesn’t fade over time. However, uPVC windows may not last as long as aluminium windows. On the bright side, uPVC windows require very little maintenance and cleaning uPVC windows is generally a breeze, making them a convenient choice for many homeowners.

Thermal Efficiency and Insulation

Here, uPVC windows shine. uPVC windows are designed with multiple chambers within the frames that act as an excellent insulators, trapping heat inside your home during winter and keeping it cool during summer. This superior thermal performance of uPVC windows can contribute to significant energy savings.

Aluminium windows, while not traditionally known for their insulation properties, have seen considerable improvements thanks to modern technology. Many aluminium windows now come equipped with a thermal break – an insulating barrier within the frame – to improve their thermal efficiency. While this has levelled the playing field, uPVC windows still generally edge out aluminium windows in this aspect.

Environmental Impact

Aluminium windows stand out for their eco-friendliness. Aluminium is 100% recyclable and retains its properties indefinitely. The recycling process for aluminium windows also uses just 5% of the energy needed to produce the primary metal. This contributes to a lower overall environmental impact for aluminium windows.

uPVC windows, while not as recyclable as aluminium windows, can still be recycled multiple times without losing much quality. However, the recycling process for uPVC windows is not as energy-efficient as that for aluminium windows.

Which is Pricier: Aluminium or uPVC?

Contrary to popular perception, uPVC windows are typically cheaper than aluminium windows. However, the final cost can depend on various factors, such as window size, style, finish, and installation charges for your chosen aluminium or uPVC windows.

Condensation on windows is a common issue, caused by differences in inside and outside temperatures. This isn’t a problem exclusive to aluminium windows. Both aluminium windows and uPVC windows can experience condensation if they aren’t properly insulated or ventilated.

Finding the Perfect Windows for Your Home

The best windows for your home depend on your specific needs and aesthetic preferences. Aluminium windows are a superb choice for those prioritising durability, modern aesthetics, and eco-friendliness. In contrast, uPVC windows are a fantastic option if you value affordability, excellent thermal performance, and low maintenance.
