Aluminium Windows vs uPVC Windows

10th December 2024

Did you know the two most popular materials for windows are aluminium and uPVC?
Both materials have their advantages and suit different styles and budgets.

But when you need to make the choice between the two for your residential or commercial project, how do you know which is the best choice?

At Alimax, we are Dorset and Hampshire’s go-to manufacturer for quality aluminium windows for residential or commercial properties. As experts in the industry, we know everything there is to know about the various options and materials.

So, here, we take a closer look at aluminium windows vs PVC windows to help you decide.

So What Is The Difference Between Aluminium vs Pvc Windows?

In the discussion of aluminium windows vs PVC, there are several differences worth pointing out.

Aluminium window frames are slimmer 

Of course, one of the major things homeowners consider when choosing their new windows is how they will look when installed into their home. As aluminium window frames are much thinner than their bulky uPVC counterparts, they provide a sleeker and more modern aesthetic that boosts the kerb appeal of any home.

uPVC windows are bulkier than aluminium window frames, meaning their look is slightly more apparent. With this in mind, uPVC frames often work well in traditional homes or cottages because they have softer, rounded frames.

Aluminium frames are strong

Though they may be slimmer than uPVC frames, aluminium windows are incredibly strong. This allows them to hold larger panes of glass to create a grander window that lets natural light flood into the room. It also means aluminium bi-fold and sliding doors are perfect for framing a beautiful view of the garden as there’s less frame spoiling the outlook.

Additionally, aluminium windows are able to weather storms better because of their strength. They will stay standing throughout heavy storms and intensive UV exposures without warping or cracking.

While strong, uPVC windows are unable to hold large frames, so they need more structure to the window. This would reduce your vision across the garden or front of the property.

uPVC windows do offer resistance to salt and humidity, making them more suitable for coastal areas where corrosion might be an issue.

Highly durable 

uPVC is a durable material resistant to rotting, which means it can enjoy a long lifespan and requires little maintenance. However, uPVC frames can degrade over time and require replacing after around 20 to 30 years.

Aluminium, on the other hand, is much more hard-wearing and doesn’t degrade in the same way as uPVC or rust or warp as other materials can. This means aluminium windows can continue to look great and perform effectively for up to 45 years.

Improved thermal efficiency 

Indeed, aluminium windows were once considered to be less energy efficient than uPVC. uPVC is naturally an insulating material, which makes it inherently good at reducing heat transfer and keeping a space warm or cool.

However, advances in technology mean that today’s aluminium frames are just as energy-efficient as plastic windows.

For example, the windows made here at Alimax are very effective in reducing heat loss thanks to the inclusion of a thermal break, a clever material that is designed to prevent heat transfer through the frame. This helps to keep rooms cool in the summer and warm in the winter and helps our frames achieve an enviable U-rating.

Aluminium frames work well on all types of property 

As aluminium windows feature slimline frames and are available in a whole rainbow of colours, they don’t just work well with modern properties but traditional ones as well.

This isn’t that different to uPVC windows as these are also available in a wide range of colours and finishes, making them both versatile options.

At Alimax, we have a specialist range of heritage and sash-style windows, which complement older properties perfectly, such as Victorian townhouses, classic country cottages and art-deco style homes.
