Is uPVC better than aluminium? The benefits of uPVC windows

The classic and most recognisable window material for generations, uPVC windows blend in with most styles of home thanks to the wide colour palette applicable and inherent flexibility. uPVC is also the most visually versatile of the options available. While hardwood and aluminium come in different colours and finishes, uPVC can be completely customised to match any homeowner taste or the style of any property.

uPVC is not just relatively cost-effective but offers quicker manufacturing times too. Virtually no maintenance, uPVC provides a practical and durable window solution that can work well on a huge range of properties. They’re a British property staple, offering reliable security, efficiency, and style at an affordable price point. uPVC windows always provide homeowners with a ‘set and forget’ window solution. They’re wholly resistant to harsh weather conditions and are easily recycled at the end of their long lifespan.

What’s more, at a time when more and more of us are keen to cut both our energy bills and our impact on the environment, uPVC is winning fans for its exceptional thermal performance. It excels at keeping heat in, draughts out, and interior spaces peaceful and quiet. Making uPVC products a fantastic choice if you live near a busy road.

What are the disadvantages of uPVC windows?

Although uPVC windows are incredibly versatile, they don’t suit all property styles, such as those that require the slender sightlines of aluminium or timber. Aluminium is also much stronger than uPVC and can last up to 45 years with little to no maintenance. Lasting between 20-30 years, modern uPVC windows are strong but not as strong as aluminium. And, although uPVC windows come with a wide colour palette to choose from, aluminium windows are available in 150 RAL colours.

The benefits of aluminium windows

The most recent window material option but by no means the newcomer, aluminium windows have built a reputation for being the ideal choice in commercial and large-scale projects. With its unmistakably sleek, stylish aesthetics, aluminium’s popularity has soared in recent years. This is thanks, in part, to TV shows like Grand Designs, where it’s frequently used in striking and ambitious contemporary self-build projects. Aluminium is also one of the most aesthetically versatile materials on the market, available in any RAL colour. Slim sightlines don’t just add to the striking, contemporary feel. They also offer unparalleled levels of natural light, able to brighten any room in the home and lend the whole property an airy, spacious atmosphere.

Not only unrivalled when it comes to strength, but modern aluminium windows also offer excellent thermal efficiency. This is thanks to their innovative polyamide thermal break – a plastic barrier placed between the inner and outer aluminium frame to prevent heat escaping. Add in high-quality glass and a premium multipoint locking system, and aluminium products can deliver truly outstanding security, energy efficiency and all-round performance. They incorporate Aerogel for impressive thermal performance, delivering U-Values as low as 0.9.

Aluminium window products almost always sit at the most expensive end of the scale – but in return, you get arguably the best all-round performance, including excellent security, durability and functionality. Available in a range of styles including casementtilt and turn and as bay windows, there’s an aluminium solution to suit any home improvement vision.

So, is uPVC or aluminium the best window material for you?

Your decision to opt for either aluminium or uPVC will largely be dependent on your budget, ambitions, and property needs. If you’re lucky enough to live in a listed building or conservation area, for example, uPVC make sense as they can be specially styled with classic design features in mind. Those living in a new development and are having window issues, on the other hand, will most likely want to consider sleekly styled aluminium frames.
