Aluminium V UPVC

Which one will better suit your project?

Choosing the right material for your project

The chances are that if you’ve researched replacement windows and doors, you’re already aware of UPVC. This white, plastic like material continues to be used all over the world for a number of reasons. In the last few years, however, another material has been growing in popularity: aluminium.

Both materials have their good points and bad points, so we thought it would be a good idea to pit them against each other. Which one will better suit your project? Hopefully we can help you find out here:


There’s no getting around this one: aluminium is much more expensive to use in doors and windows than UPVC. One of the reasons that UPVC has become so popular, in fact, is that the development of mass production for it has kept prices fairly static since it was introduced back in the 1970s. Aluminium, on the other hand, simply can’t be manufactured in the same way because of its reliance on raw materials.

Of course, price isn’t everything: as you read further down the page you may find that the benefits of using aluminium far outweigh the potential increase in cost. It’s also worth bearing in mind that as aluminium becomes more popular, more product options will become available and prices will probably lower as a result.


This probably won’t surprise too many people, but aluminium is far more robust and durable than UPVC. It’s not that UPVC windows don’t have a long life – they do – but they simply can’t rival the toughness that solid metal can, especially if it’s well looked after and maintained. If you want strength and nothing else, aluminium is definitely the right choice for you.

Profile size

If you prefer your windows to look thinner and sleeker, aluminium is once again the better option here. The extra strength that it offers means that frames made using it can be made much, much thinner. In turn, this means that the glass used can be wider and more light can be encouraged into the property. As well as being visually appealing, this is actually something that can save you money on your bills in the long run.


If you’re the sort of person who values peace and quiet above all else, then you should definitely look at UPVC. The plastic construction makes it an extremely competent insulator, certainly far superior to aluminium in this regard: if you live in a noisier than average area, UPVC is definitely the material for you. Aluminium does provide some noise proofing of course, but it reverberates in a way that actually suits travelling soundwaves, so it’s not ideal and certainly the inferior option.


Both materials are actually excellent in this regard. UPVC is very reliable and constructed to be extremely difficult to break or damage. Aluminium, though, arguably offers an extra level of resistance on top of this: it is, after all, solid metal. Whichever material you use, though, you’ll be happy with the results as relates to the security of your home.

Heat insulation

In this category at least, UPVC is definitely the standout material. The plastic base makes it incredibly efficient at maintaining heat levels. You don’t have to take our word for this of course: just head out on any chilly winter day and touch a lamppost or a warehouse-style door! This doesn’t mean a high-quality aluminium door won’t maintain the heat, of course: just that it won’t do it to the level of UPVC.
