Should you choose uPVC windows or aluminium windows for your home? If you’ve been looking to enhance your home with some new windows, then you’ve most likely taken a look at uPVC designs. After all, uPVC windows are the UK’s most popular option, and it is easy to see why they’re so loved across the country. uPVC is a durable material, meaning its fully weatherproof and will last for decades, and it offers excellent insulation for your home as well.

However, there is an alternative option to uPVC windows – aluminium windows. Aluminium is a precious metal, meaning it has more strength than uPVC, and its more durable as well. As a result, aluminium windows last longer, are more secure, and even have a sleeker look thanks to the metallic designs these windows come in. And, although they may be more expensive, aluminium windows could provide similar or even greater value than uPVC windows over time.

So, which should you choose: uPVC windows or aluminium windows? At Chigwell Window Centre, we have an objective view on whether you should choose uPVC windows or aluminium windows for your home, as we manufacture both in-house. Our windows are market-leading whatever material they come in, meaning you can enjoy superior performance in your living space with any of our designs. Read on below to find out which you should choose, or get a free online quote today!

uPVC Windows vs Aluminium Windows – Efficiency

One department where uPVC windows usually perform well is thermal efficiency. Efficiency refers to how well a window is able to hold the heat inside your home and insulate it from cold air outside. uPVC is a natural insulator, and the profiles in our windows are air and water-tight to stop draughts and damp spots playing havoc with your home. When combined with advanced double or triple glazing, then, uPVC windows can help you stay warm all year round.

In the old days, aluminium windows were more known for their lack of thermal efficiency. However, at Chigwell, our in-house aluminium windows use market-leading profiles that are intelligently designed to trap small pockets of warm air inside your living space. Because of this, our aluminium windows are able to perform just as well as uPVC windows. Both of these designs can save you money on your energy bills and decrease your carbon footprint!

uPVC Windows vs Aluminium Windows – Security

When it comes to the security of your home, uPVC windows aren’t it – aluminium windows are the only choice. While uPVC is a durable material, it can be a little flimsy and may not resist the heaviest impacts, such as hammers. Aluminium windows, on the other hand, are incredibly strong and rigid, meaning they can deal with even the most violent attacks. You can be sure that your aluminium windows will still be standing no matter what a burglar or an intruder tries to do to them.

Aluminium is inherently a more durable material than uPVC, as well. Because of this, your windows will secure your living space for longer, and the profiles will also conceal and protect the internal security hardware from wind and rain. Devices like multi-point locking systems, shootbolts and more will work at their best for decades as a result, protecting you from any potential threats. So, for complete peace of mind, aluminium windows are better than uPVC windows every time.

uPVC Windows vs Aluminium Windows – Cost

One factor that could make uPVC windows more attractive than aluminium windows, though, is how much they cost. While aluminium windows probably offer better performance overall, you usually have to pay a premium to enjoy it. uPVC windows, on the other hand, are more affordable, and they’re more versatile as well. For example, if you have a traditional home, uPVC blends in more seamlessly with wood and brickwork than sleek aluminium.

For the most part, you end up having to pay a 20% premium for aluminium windows compared to uPVC windows. What you have to ask yourself when comparing both options is whether you need the increased performance. If you’re looking to make your home more secure, more soundproof and more efficient to ensure it performs, aluminium windows are the right investment. However, if you’re only looking for a window that does the job and are less concerned by the performance, uPVC windows are more affordable every time.
