Choosing windows is not as easy as it seems.
From varying designs to different colours and textures, there's plenty to consider. And that's before we get into the nitty-gritty of the material they're made of.
Two of the most popular materials for windows are
aluminium and uPVC . Both have benefits aplenty – but which option is best for you?
Let's have a good look at their pros and cons. This way, you'll have all the information you need to make the right choice for your home.

Aluminium windows: the pros

1. Long lifespan


Aluminium replacement windows
make for a great investment because, in the long term, you're going to get your money's worth. Aluminium windows have a lifespan of anything from 30 years upwards, meaning replacements will be a long way off.


2. Durable


The reason these windows have such a long lifespan is that
aluminium is a very durable metal. Even extreme UK weather can't shake them!

3. Lightweight and versatile 


Aluminium is a very lightweight material. This makes it extremely versatile as it can be used for things like large statement windows and skylights.
As the profile of the window tends to be thinner due to the material, it also allows a little more natural light to flow through your home.

4. Low maintenance

If maintenance isn't your strong suit, aluminium windows are the right option for you. Unlike wooden frames, aluminium needs very little maintenance. A quick rinse while you clean your windows is all they need to stay in tip-top condition.


5. Recyclable 


Another little bonus with aluminium windows is that they're 100% recyclable. When they reach the end of their lifespan, the old frames can be melted down and used for something else. Perfect!

Aluminium windows: the cons


The only real disadvantage of aluminium windows is their cost. Aluminium windows usually cost a little more than their
uPVC equivalents.

This is due to various factors. The material, its durability and the lifespan of the windows all contribute to the price. In short, you're getting a longer-lasting product so you have to pay a little more.


uPVC windows: the pros


1. Energy efficient


uPVC windows are known for their energy efficiency. They're highly effective insulators and can help regulate the temperature inside buildings all year round. This type of window can help reduce the heating costs – especially if they're fitted with double or triple glazing.

2. Affordable


There's no two ways about it. Out of uPVC and aluminium, uPVC comes out on top in terms of pricing. If you're working on a tight budget, these windows are the preferred choice as they allow you to upgrade your home without breaking the bank.


3. Durable


Both aluminium and uPVC are man-made materials that don't expand or contract. This means they won't warp or crack in the same way as other materials and can be easily maintained with some light cleaning.


4. Long lifespan 


Like their aluminium counterparts, high-quality uPVC windows will last for years with proper care. You can expect to get 20 to 25 years of use from a uPVC window before it needs replacing.


uPVC windows: the cons 


Similarly to aluminium, the disadvantages of uPVC windows are very limited. Nonetheless, we will run through some of the standout issues.
First, uPVC isn't quite as durable as aluminium. This means that uPVC windows are more susceptible to damage as the material can be more easily marked, dented or cracked. However, they're still very robust and can withstand a significant amount in terms of weather and regular wear and tear.


uPVC has excellent insulating properties which can result in dirt and debris clinging to the windowsills and frames. Unfortunately, this means they may require a little more cleaning than the aluminium counterpart. However, if you're not shy with a bucket and sponge, this won't be an issue.
A word on style We haven't considered style an advantage or disadvantage, because, ultimately, it comes down to personal taste. Some consider aluminium windows to be a little more stylish because they tend to have slim frames. This gives them a crisp, modern look with a slight industrial flavour. uPVC windows, on the other hand, have a more "typical" look that's arguably more versatile.

Again, it's a question of taste. But you can think of it like this: if you want to stand out, choose aluminium. If you just want some classic-looking windows, uPVC will do just fine.
