Lightweight, strong and durable – these are just three reasons why aluminium is a great choice for window frames. Slimmer than most other window frame designs, the glass panel can be larger, giving you more light and better views from your home.

Aluminium windows can transform both the exterior and interior of your property. We manufacture our aluminium windows in our own bespoke factory, right here in Clevedon. This means we can tailor them to match the specific style you have in mind. Whether you want to match your new windows with historical steel windows or create a modern masterpiece, we are here to help.

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.
