uPVC vs aluminium slimline windows – which should you choose?

If you’re in the market for new windows, you’ll be faced with an overwhelming number of options. From different styles and glazing options to security features and much, much more, choosing the right windows for your home or business can seem like a daunting task.

One of the most obvious choices you’ll have to make is the window frame material. You could go for traditional wooden frames, but most opt for either uPVC or aluminium window frames. If you’re struggling to weigh up the pros and cons of uPVC and aluminium windows, we’re here to do the hard work for you! Let’s take a look at the plus points of each.

uPVC windows

uPVC windows have dominated the market for many years now, although they are beginning to cede some of their market share to aluminium (we’ll get to the reasons why later). Nevertheless, uPVC windows have a lot to offer. Here are some of the stand-out benefits…

• They’re the most affordable option
• They’re highly energy efficient
• They require very little maintenance
• They can last for quite a long time compared to wood frames

Aluminium windows

Aluminium windows are still seen as more of a left-field choice, but that perception is changing. They may be pricier than their uPVC counterparts, but when you take a closer look at the advantages they offer, this should come as no surprise. Here’s a roundup of the advantages of aluminium windows.

• Aluminium is extremely durable and strong
• The material won’t rust or fade over time, allowing it to comfortably outlast uPVC
• It requires no more maintenance than uPVC
• It looks the part and is available in a wider range of colours
• It can be just as efficient as uPVC
• Aluminium windows can feature thinner frames, allowing more light into your home

In fact, the only real downside of aluminium windows is that they’re a little more expensive to buy. But the price differential might not be quite as much as you’d think.

So, which should you choose?

The reality is that both materials have their upsides – and both have their downsides. If you’re on a somewhat tighter budget, aluminium doors and aluminium windows simply may not be affordable for you – but if you can afford the additional cost of aluminium windows frames, the advantages are clear.

Not only are they more durable than their uPVC counterparts, they’re stronger, allow more natural light inside and are more customisable – you can opt for practically any frame colour you can imagine. To top it all off, they can be just as energy efficient as uPVC frames thanks to innovations like polyamide thermal barriers.
