What’s The Right Choice to Make – Aluminium or uPVC Windows?

Last Updated on April 22, 2022 by Kravelv

It can be a tough decision when it comes to considering new window installation. And there is a long-standing debate as to which is better, Aluminium or uPVC. During this article, we’re going to take a look at the pros and cons of aluminium and uPVC windows to help you with making a choice. 


Thanks to the durability of both materials, aluminium and uPVC windows are very secure, unlike timber windows that can be quite vulnerable when it comes to forced entry. No matter whether you choose aluminium or uPVC (provided you have multipoint locks) you can rest assured knowing that your windows are secure and your property safe. 

However, one of the biggest advantages of UPVC windows compared to aluminium is that they are much better when it comes to soundproofing your property. We’re not saying that aluminium windows are bad at soundproofing, but uPVC are far better. However, there may be some certain companies that offer double glazing spares and parts that could help further soundproof uPVC.


uPVC windows have been a popular choice amongst homeowners since the 80s. It’s an exceptionally durable material which means it requires very little maintenance and has a long lifespan. However, uPVC frames can degrade over the years and typically need to be replaced after about 20 years. 

Aluminium windows are also exceptionally durable, but they can last up to 40 years. Additionally, unlike other metals, aluminium doesn’t rust so you haven’t got to worry about your windows looking poor in years to come. 

Energy Efficiency

In the past, aluminium had always been deemed as less favourable amongst homeowners because of its low thermal efficiency. It’s a highly conductive material, so heat can pass through it easily. Therefore, uPVC was seen as the better option for quite some time. 

However, over the years, technology has come a long way, and aluminium windows now come with thermal breaks within the frames which makes them so much more energy-efficient than what they used to be. 

Ultimately, the level of energy efficiency really does come down the quality of materials used during the manufacturing process. 

The Aesthetic Differences

One of the biggest reasons aluminium windows have grown in popularity over the years is because of how great they look. They are much slimmer than uPVC windows which gives them a sleek look that further complements even the most modern of homes. It’s also worth mentioning that despite their slim frames, aluminium windows are strong enough to hold heavy panes of glass. 

On the flipside, uPVC windows have a reputation for being rather ugly, and they’re not very appealing for homeowners looking for something a little more attractive for their property. White uPVC is one of the cheapest materials, which is one of the biggest reasons why it’s the most common colour seen up and down the UK. 


Aluminium windows are typically more expensive than uPVC because the costs of materially and manufacturing are considerably higher. However, aluminium degrades slower than uPVC, so it’s a more cost-effective solution in the long run if you plan on spending many more years in your current property. 

Furthermore, aluminium windows can add more value to your home compared to uPVC, which makes them an investment worth making. When considering price points, it’s important to compare aluminium and uPVC where possible to ensure you get the best possible deal. 

The Verdict

When it comes to aluminium vs uPVC, it really isn’t a cut and dried competition. It all comes down to your personal requirements, your budget and the factors that apply to the type of property you live in. Everyone is completely different, and because they both have their advantages and disadvantages, it’s not as simple as saying that you should choose one over the other. 

Aluminium has grown in popularity over the years because of its thermal efficiency and durability. But, there’s always going to be a place in the marketing uPVC because of its affordability.
