Aluminium Windows VS uPVC Windows: What’s Best for Your Home?

(3 min read)

When considering replacement windows, the most popular choices are Aluminium Windows and uPVC Windows. Each has its own benefits. Let’s explore those benefits to help you when it comes to choosing your new windows.

Benefits of Aluminium Windows

Aluminium Windows are very popular right now. They tend to be particularly popular for more modern-looking properties but they can still be used in period renovations and homes of all eras.

Thermal Efficiency

Aluminium windows are also known for having a great amount of thermal efficiency, though the frames may feel colder to the touch.

Window Lifespan

The lifespan of aluminium can be longer than other alternatives. Usually, you would expect up to 40 years of use from them before needing to replace them. They are incredibly resilient to warping, flexing, and corroding, thus adding to their lifespan.

Aluminium Window Disposal

When replacing aluminium windows, they can be 100% recycled. This makes for a more environmentally friendly product. While replacing these may not be an issue to think about for the first 40 years, you or a future homeowner may decide to do so later, and a fully recyclable product will be much easier to dispose of.


As well as being durable, aluminium windows are also incredibly easy to maintain. A quick and simple clean every few months is enough to keep them looking their best, removing dirt and keeping them nice and shiny.

Benefits of uPVC Windows

uPVC Windows are often the first choice for anyone looking to replace their windows. They are often the cheaper option compared to others, they come in a wide range of customisation options, and they promote good noise reduction capabilities. Like aluminium windows, they are also easy to maintain.


uPVC is a low conductor of heat, meaning the loss of heat through the windows will be minimised. This will assist in keeping the home warmer for longer, helping to keep energy bills down. They prevent dampness and cold air from entering the home, and the uPVC frames help to retain the heat already inside the home.

Window Security

uPVC is surprisingly resilient, making it a fantastic material security-wise. These frames are made in a way that makes them burglary-proof, often making them a deterrent alone to potential intruders due to how difficult they are to force open. They can also be fitted with certain hinges or locking mechanisms to make them especially safe when children are around.

Style and Versatility

These windows can come in a wide range of colours, styles (casement, bay and bow, and tilt and turn) and finishes, with different furniture and hinges as well. They can be customised in virtually endless ways, meaning you will always be able to find the perfect match for your home.

We recently decided to replace our front door, and could not be happier with the result! Thanks so much to Kate, for her time and understanding. Cannot say enough good things about the installation, and Cameron was tidy and efficient. It's been a pleasure to work with Three Counties recently, doors and windows. Many thanks!

Just had my tatty old windows replaced by Three Counties, and it’s been a highly professional job from start to finish. Communication from the administration team was prompt and courteous at all times, and installation ended up being much quicker than advertised projections. Installation was without issue and the lads who did the work were amenable to my requirements and did an excellent job. Very happy with the entire process. Three Counties were recommended to me by friends and I can certainly now recommend them to others.

Bought two new windows and a new front door from Three Counties, was very impressed with the attitude of all staff, who were friendly and informative. Price was good, and installation completed without a hitch - very happy with the final product, and would definitely use again.

We have just had all our windows (18) replaced, french doors (20 and side panels (2) by Three Counties. We could not be more pleased with their workmanship and the finished product. They left the property incredibly clean after each day, and this despite the messy nature of ripping out old windows and frames. We were kept informed at each stage and a minor snagging issue was resolved promptly and efficiently after installation. A first class service. We would not hesitate to recommend Three Counties.

Three Counties have now installed several windows and doors on our house and they're always my go-to company. I used another before I discovered them and they let me down, but I absolutely cannot fault Three Counties. From the moment you contact them they're courteous and professional, and they keep in touch with timescales and installation times. Friendly installers too, who go above and beyond. You'd think all this great service would cost more but they beat other companies on price. Highly recommended and trusted, I'd never go anywhere else now.
