Before we begin, let’s take a look at what uPVC is. First of all, uPVC (un-plasticised Poly Vinyl Chloride) is a common window material that has been used since the 1980s. The features it has are that it is tough, resistant to rot and requires almost no maintenance. Many people choose uPVC windows as it is a very popular choice among homeowners. On the other hand, aluminium windows are more of a modern material that has high aesthetics with the immensely high performance so it can meet demands of a variety of properties; also, it gives a modern feeling to the property as well. During the past few years, aluminium windows popularity has raised due to their appearance for home improvement in the TV show ‘Grand Design’. However, what is the difference between these two windows? Well, let me tell you.



For uPVC windows, it normally has a longer lifespan while the frames can possibly degrade over many years. On the other hand, aluminium is a much sturdier material for the window frame, since it can last almost forever if you take proper care of it. It is also it quite low maintenance as well.


Sound Proof

uPVC window has better insulation capability than aluminium windows, as uPVC window was mainly designed to be a capable insulator. It offers maximized soundproofing capability for homeowners especially for those who live in a busy built-up area. Compared to aluminium, uPVC windows are the winner for soundproofing and this is one of the reasons for its popularity.



Having a visually appealing window is one of the important features, as it can make your home more attractive in appearance for the inside and outside.  It always important to consider the style of your home, since by having a visually aesthetic window it can increase the value of your home. Aluminium has an extremely sleek appearance so their frames can make attractive views from the outside and inside of the house. Although they have a slim profile, it still has the capability to hold large glass panes due to their sturdy durability, therefore, allowing for the maximum amount of natural light to go into your home. Comparing this to uPVC, aluminium is better in people’s eyes since looking at white plastic from afar is not attractive as some homeowners feel that the frame is to plain looking. However, both materials can be coloured in your style, but if we are talking visually then aluminium wins this time.



Every homeowner wants a window that requires little to no maintenance so they don’t have to waste time worrying about it. uPVC would be the best option as the material is easy to maintain, since the material is high defined plasticised material meaning that it is easy to clean just need a simple wipe-down if they get dirty. On the other hand, aluminium windows are extremely sturdy making them resist corrosion and it is entirely weather-proof. This makes them look brand new like the day it was installed as they will never rot or warp.


Energy Efficiency

Having an energy efficient window will improve your home as it increases its energy efficiency and it can help you save money on heating bills. So, having a modern uPVC are actually great thermal insulators and a contemporary uPVC makes use of a simple internal profile so it can use thermal retention at its full potential. Whilst aluminium windows have innovative polyamide thermal break which makes them attain the same levels of energy efficiency as uPVC. Aluminium windows can do the same as uPVC by maximising thermal retention making your home warmer for a long period of time. So, you can’t really go wrong with energy efficiency between uPVC and Aluminium.
