Aluminium vs uPVC: Considerations

There aren’t really too many disadvantages to aluminium or uPVC windows but you can see some of things you should bear in mind below:

Aluminium Considerations uPVC Considerations
Aesthetics Aesthetics
Condensation Lifetime

When it comes to the aesthetics of a window, it’s often down to personal taste and whether they’ll suit the type of home you live in, so this consideration is debatable for both. If the appearance of your home is a high priority when installing new windows, aluminium and uPVC might not be the best choice so you might want to consider timber, however on the right type of home, aluminium windows can offer a sleek modern look.

Something to consider with aluminium windows is that they’re susceptible to condensation forming as the material is a good conductor of heat. While this is a disadvantage, you don’t have to live with it thanks to thermal breaks.

While they’re the cheapest option, you’ll be replacing uPVC windows sooner than many other materials but that might not matter if you have a tight budget.
