Aluminium has a good strength-to-weight ratio – it's very strong despite being rather light. This makes it suitable for all sorts of products and means it has a long lifespan. You can expect an aluminium door or window to last up to 45 years, while its uPVC equivalent might last 25 to 35 years.
And let's not forget about style. Aluminium has a crisp, contemporary feel that will turn heads and bring a modern look to your home.
It's impossible to give an exact figure. We provide tailored quotes because each job is unique to your home.
That said, aluminium doors and windows are generally a bit pricier than their uPVC counterparts. If you can afford to pay a little more, you'll be rewarded with extra durability and a stylish, modern finish.
Graphite black is one of the most popular and enduring colours. However, it's far from your only option. Our aluminium doors and windows are available in a wide range of colours and finishes, including classic cream, metallic grey and matt green.
Yes. In fact, our aluminium windows come double-glazed as standard. Triple-glazed options are also available.
Our aluminium doors and windows require very little maintenance. This is thanks to a strong powder coating that's specially designed to resist marks and scratches – even in coastal areas and inner cities.
To clean them, simply wipe them down with a soft cloth and a mild detergent. They'll soon look as good as new. Don't use bleach or abrasive cloths as these can damage the powder coating.
Aluminium is one of the most environmentally friendly building materials in the Universe. Not only is it very durable – meaning it stays in use and out of landfill – but it's 100% recyclable.
And unlike plastic, aluminium can be recycled indefinitely. It truly lasts forever.
