Stylish, Sleek Aluminium Windows
If you’re looking to bring your home into the 21st century, aluminium windows can make a huge impact. Following the latest trends in architecture, these double glazed windows have some of the slimmest sightlines available. As a result, these double glazed windows will let the largest amounts of natural light into your home.
They may be slim, but aluminium is one of the strongest materials for your windows. They require little to no maintenance as the material is naturally rust resistant. This also means that they are very secure windows as they are very difficult to break into. For a great performance from your home improvements, aluminium windows will fit the bill.
Thermally Efficient, Customisable
For many homeowners, the number one concern when looking for new windows will be energy efficiency. This is for good reason too. Energy and heating bills are growing more costly as time goes on. You can combat this by upgrading to modern aluminium windows. Double glazed as standard, but with options for triple glazing you can prevent heat loss to keep your energy bills at a minimum.
We offer an unlimited range of colours in a variety of finishes and a choice of over 85,000 components. This is owing to our in house manufacturing process here in Clevedon. You’ll be able to make sure your aluminium windows are perfect for you and your home.
Frequently Asked Questions
Do aluminium windows rust?
Unlike many other metals, aluminium does not rust. The metal itself is prone to corrosion, but all Britannia aluminium window frames have a powder coating that prevents this from taking place.
Are aluminium windows better than uPVC?
Both aluminium and uPVC window frames have their benefits. uPVC windows are made from a type of tough plastic and are often more affordable than aluminium windows. With advances in modern technology, uPVC windows can also be equally energy efficient and secure. Aluminium windows are strong and aesthetically pleasing.

Happy Customers
Meg Welch
Great job of our new front door. They couldn’t have been more helpful and even fitted earlier than originally planned. Also gave great aftercare advice and at a very reasonable price! Would 100% recommend.
Annette Clemons
Cannot recommend Britannia Windows enough! Joe & Keith, the installers were great – explained what was to be done, showed me everything I needed to know upon completion, very considerate & tidied up really nicely. Very friendly guys who are an asset to the team!!
I LOVE my new windows & door. Such an improvement.
Rachel Godfrey
We have been extremely pleased with Britannia’s service. From the initial quote through to installation they were great and really easy to communicate with. We had our conservatory roof replaced and they were by far the least pushy and most competitive in terms of pricing.
We can definitely recommend their services and will likely be returning again soon for a new front door!
Peter Burgess
Fantastic job from initial phone call through to final tidy-up.
Britannia provided great advice before purchasing my new windows and fitted them to a high standard being punctual and polite throughout.
No request was a problem and I will definitely be using them again and would recommend to friends and family.
Jerry G
Wow a fantastic job by both sales team and fitting team.
Sam provided excellent service and answered any questions that we had. Luke, Dave, Keith and Joe did a fab job at fitting the windows and doors. Never having had anything like this done before I was a little nervous but the guys were clean and tidy and the outcome is amazing.
Would highly recommend.
