Which is Better, Aluminium or uPVC Windows?

(3 min read)

When looking at replacement windows, the usual choices are going to be aluminium or uPVC. Each has its own benefits. This post will explore those benefits, which might help you when it comes to choosing your new windows.

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.

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.

Conclusion, Aluminium or uPVC Windows?

Both of these options are incredible choices. It’s really up to you to choose which works best for your home. If you need any help or advice, please don’t hesitate to contact us at Three Counties, and we would be more than happy to give you a hand with deciding.

We used Three Counties to replace our front door and porch. Throughout the process, from design, quote, survey and installation the service and level of communication has been fantastic from all involved. The installation team were great, friendly and courteous, working cleanly and tidying up after themselves. We would have no hesitation using Three Counties again, or recommending their services.

Fantastic service from start to finish. Kept me upto date all the way through the process. Very prompt coming out to measure up and discussing what windows I would like. The install was done professionally by a fab team (James and Josh), cleaned and tidied as they went, friendly team. Would highly recommend

Very happy with Three Counties. That’s the second time we have ordered services from this company and both times it was flawless. Prices are very competitive, customer service very good and workmanship excellent. I trust this company 100% and will be definitely be using them in the future. Paul, gentleman who fitted the door, done an amazing job. There is nothing there that person like myself (with slight touch of OCD) would have an issue with. Highly recommended local company that you can trust.

We used Three Counties to replace 7 windows at our property in February 2022. From the initial quotation, through survey to installation I was extremely impressed with them. The installation was completed by Dan and Cam who I cannot praise highly enough. Their workmanship and attention to detail / finishing was exemplary. They were polite and worked hard / efficiently to complete the job in 1.5 days. They took great care to protect carpets and furnishings whilst working and spent time tidying up, leaving the property very clean. I would not hesitate in strongly recommending this company.

The quote was the price (no hidden extras).The quality of the doors we purchased and the fitting of them was top notch It is nice to find a company that keeps you informed as regards fitting etc at all times We had a problem through no fault of 3 counties and they sorted it efficiently and effectively.We were kept up to date at all times. I have no hesitation in recommending them to anybody thinking of any form of double glazing. This revue would not be complete without a big thankyou to Kate and the fitters.

We are so pleased with our new bi-fold doors supplied and fitted by Three Counties. The job was done professionally and in the time frame provided. Dan and Cam took the upmost care on installation to ensure everything was perfect and they were a pleasure to deal with. Credit to the administration team also who kept us fully informed of the process and schedule. I would highly recommend Three Counties for their workmanship and already have to our friends, who have employed them to do their conservatory
