Aluminium is the ultimate 21st century material; it excels in both its performance and appearance. Aluminium windows can be designed in over 150+ RAL colours. Along with their unique slimline frames, they can easily complement both modern and more traditional properties because of the plethora of colour choices. You’ll benefit from superb performances, including enhanced thermal insulation, home security and noise reduction. And they’re maintenance-free, so they’ll look and perform like new for at least 45 years. With their thin and lightweight frames, they’ll let in plenty of natural light for a bright and airy home, whilst adding value to any property.
Aluminium is a thermally insulating material, and those thermal abilities can save you money on your energy bills
Aluminium’s innate strength and sturdiness means it can hold larger panes of glass
Aluminium frames provide super slim sightlines, so you have an unobstructed view of the outside
Aluminium is robust and can last for more than 45 years
Aluminium frames undergo rigorous extrusion mechanisms, with the profiles being welded together to a specific shape. During this process, they are fabricated to minimise the heat transfer of cold elements with thermal break technology. That's why aluminium windows offer unparalleled security and durability. The innate strength allows for large panes of glass to be held and with the edge of the aluminium frame being as close as 50mm to the glass, you can take advantage of more views.
With slim frames it allows for wider expanses of glass and unobstructed views of the outside
Featuring a unique polyamide thermal break, our thermally broken aluminium frames achieve A+ energy ratings and low U-values with ease.
Finished in an anti-fade, anti-rust and anti-corrosion coating, our aluminium windows are exceptionally strong and weather-resistant.
Able to last up to 45 years, the majority of our aluminium windows are tested to PAS 24 as standard.
Durable, strong and endlessly recycled, aluminium is one of the most sustainable construction materials available.
Backed by a 10-year guarantee and a commitment to exceptional craftsmanship and customer satisfaction.

Aluminium windows provide excellent levels of energy efficiency. With U-values as low as 0.9 W/m²K and an energy rating of A+, you’ll soon see an improvement in your home’s performance and a significant reduction in your heating bills. Aluminium achieves such outstanding thermal performances through a number of sophisticated features. This includes thermally broken frames which keeps the heat inside and stops any draughts from entering by breaking up currents of airflow. Aerogel is included to further enhance the insulation abilities, as well as either our high-quality double glazing or comfort glass and warm edge spacer bars.
If you’re looking for an environmentally friendly window material option, aluminium is a great choice. It is 100% recyclable material and loses almost none of its quality when recycled. It can be melted down and re-formed numerous times for an extensive lifespan. When you want to reduce your carbon footprint and help to protect the environment, aluminium windows are perfect.
Get A PriceAluminium windows offer an excellent range of choices. Our range includes casement, tilt and turn and bay windows, as well as bespoke windows. These are custom designed to individual requirements, so you can choose any shape, size and style. We’ve previously installed aluminium windows in an array of shapes, including triangular, arched and round.
Aluminium window frames have a smooth finish that no other material can achieve, so it’s assured to add a premium and modern touch to any home they’re installed on. Our premium aluminium windows can be designed in over 150+ RAL colours. So, whether you’re looking for sleek grey, elegant Chartwell green or classic white, we can install the ideal solution to add kerb appeal to your property. Depending on the style, they can be fitted with either our high-performance double or comfort glass. And with a range of window furniture elements to choose from, you can add the decorative finishes to perfectly add style to your home.
Aluminium windows are popular with homeowners who are looking for a slim window frame. They boast distinctively thin frames that will add an ultramodern and sleek aesthetic. Not only do they add style, but the thinner frames create panoramic views of the outdoors, so you can enjoy the views from the comfort of your home. They’ll allow an abundance of natural light to flood into your home, for a bright atmosphere inside.
Although the design is formed of larger glazing panels and slimline frames, it still excels in its thermal insulation performances. With a draught-free design and high-tech frames, your home will be kept a comfortable temperature all year round.
Get A PriceAluminium is a naturally strong material and is the most durable construction material you could choose for your new windows. So, you can be sure that your home is protected. Its inherent strength allows large areas of glazing to be supported with slimline frames.
All of our aluminium windows have undergone rigorous testing and they meet all the current Building Regulations requirements for total peace of mind. We also test the security measures to common burglary methods, so they’ll keep unwanted intruders out of your home.
We fit our range of aluminium windows with multi-point locking systems as standard to ensure that home security is maximised. Multi-point locks bolt the windowpane to the frame at several points, significantly increasing their resilience. So unlike older locking features which are only secured at one point, our aluminium windows will stay intact from extreme forces. If you’re looking for even further home protection, we can include additional security measures into your bespoke aluminium windows.
Get A PriceWhen you’ve had our modern aluminium windows installed, you’ll instantly reap the benefits. With high performance double glazing to provide superior noise reduction, it means that the outdoor noise, from roads, people and planes, will be kept outside. You’ll be able to relax in peace and quiet and experience a much better standard of living.
Get A PriceIf you’re looking for a replacement window option that will last for years to come, then our high-performance aluminium is for you. They boast a lifespan of at least 45 years, and with just basic maintenance they could continue to perform for even longer. We suggest just wiping the frames with a damp cloth every so often to remove any dirt.
We finish the aluminium frames in a powder-coated protective layer which stops the colour from fading. It also protects the frames from rotting, corroding and splitting. Our premium aluminium has a triple weather seal, so whatever the conditions outside, they won’t weaken in their performance. So not only will they look like new, but you’ll still be benefiting from their excellent performances for many years.
