When the time comes to upgrade the windows in your home, it can prove to be a daunting time. There?s so many options to choose from, whether it?s material, style, colour, features, or something else.

One common decision that people have to make when choosing new windows is whether they would like to go with uPVC windows or aluminium windows. But it?s not so clear which one to choose.

That?s why we?re going to look at what the difference is between uPVC and aluminium windows (other than the obvious of them being different materials!).

uPVC windows vs aluminium windows

Here we will take a look at some of the main aspects that are commonly looked for when having new windows fitted, so that you can easily see what the differences are between uPVC and aluminium.


If budget is tight, uPVC windows are generally the better option. uPVC is often cheaper than aluminium, due to the differences in cost of manufacturing and installation.

uPVC is often seen as good value for money, as the initial investment is lower and they have a long lifespan and are able to withstand the British weather, but they aren?t as robust as aluminium windows.

Energy efficiency

It?s commonly thought that aluminium windows are less energy efficient than their uPVC counterparts. But this simply isn?t true.

Whilst aluminium windows can often feel colder when touched, the frames themselves can provide the same levels of energy efficiency as uPVC frames.

Style and design

uPVC windows are highly customisable. Usually, you can choose from almost any RAL colour, allowing you to have the window designed to suit the rest of your home?s style. But there?s no getting away from the fact that, at the end of the day, it is plastic.

For a more premium feel, particularly on modern or new build homes, aluminium windows have the edge. They have the ability to provide thinner frames which improves the sightlines and creates a less obstructed view of the outside world.


When it comes to your home, security is important. Whether it?s protecting your family or belongings from would-be intruders, or keeping children safe, both uPVC and aluminium windows are as secure as one another.

Both window materials come with reinforced frames, in addition to having multi-point locks fitted as standard. In some cases, upgrades are available for an additional cost to enhance the security further, such as adding smart locks.


Both uPVC and aluminium windows are easy to clean, usually requiring just a wipe down with a wet cloth.

Neither material should warp or rot.


Whilst the longevity of your windows will depend on how well you keep on top of maintenance (such as regular cleaning, repairing any damage, etc), there are some general rules of thumb for the longevity of each window type.

uPVC windows typically last around 20-35 years before a replacement is recommended.

On the other hand, aluminium windows typically have a lifespan of around 45 years.

Going back to the earlier point on price, whilst uPVC windows are a lower upfront investment, they are likely to be outlived by aluminium windows.
