Aluminium windows vs UPVC windows: Which is best?

[aluhm]

When it comes to aluminium windows vs UPVC windows, both materials boast some great benefits.

Obviously, these will appeal to different types of homeowners, but the reality is there's no 'right' answer about which one is best.

Ultimately, whether they’re the right choice for you and your property will depend on many different factors...

Price
In terms of price, installing aluminium windows is always more expensive than UPVC (on a like for like basis) because of higher material and manufacturing costs. But, in the long term, aluminium can prove very cost-effective because it’s a more robust material than UPVC.

For a more affordable initial outlay, UPVC windows offer a superb ‘fit and forget’ window solution because they’re highly resistant to rot with a long lifespan.

For a typical sized home, the price difference when comparing aluminium to UPVC would probably be thousands rather than hundreds of pounds.

Thermal efficiency
Obviously, UPVC is a great insulator and these windows (above) offer a very high level of thermal efficiency.

With aluminium windows, there’s a common misconception that they are not as well insulated as UPVC, but this is not true. The frames may feel colder to touch, but the window panes can achieve exactly the same energy efficiency levels.

This is done by using a thermal break, a barrier which prevents aluminium-to-aluminium contact from the inside to the outside of your window, to keep the inside of your home warmer for longer.

In short, both UPVC and aluminium offer excellent levels of insulation.

The aluminium windows vs UPVC windows debate is far more complex than saying one is better than the other.

Aluminium windows summary: Slightly more expensive, but they last for ages and are a good long-term investment. From a design point of view, they’re modern and stylish with sleek profiles and sightlines. Probably best suited to modern homes (as shown above).

UPVC windows summary: Affordable to install, UPVC window frames are super stylish and – thanks to advances in plastic technology - they now come in a variety of colours, including anthracite grey (shown above). Their subtle appearance is ideal for older properties and listed homes.
