Why Choose Aluminium Windows?

Aluminium is commonly hailed as a ‘magical metal’. It possesses many intrinsic properties that make it ideal for use in a variety of applications, including window frames. As the market for aluminium frames grows year on year, discover why homeowners are turning to this ‘magical metal’ for their windows.

Aluminium is a sturdy material with an exceptional strength-weight ratio. Not only is it difficult to dent, aluminium is also resistant to rusting, rotting and bending. This resilience lends aluminium a long lifespan of up to 30 years.

Aluminium is also the ideal choice for sliding doors and bi-folding doors. Unlike PVC and timber, aluminium barely expands or contracts with temperature changes, nor does it warp or twist, meaning sliding/folding doors are always easy to open and close.


Available in many shapes and colours

Aluminium is an ideal material for satisfying different design requirements. It can bend easily while still maintaining its inherent strength, meaning it can be manufactured to various specifications. Aluminium windows are a perfect choice for oddly shaped or oversized windows. They can also be finished in a wide range of RAL colours to match any home aesthetic.


100% recyclable and environmentally friendly

Aluminium is one of the easiest and most effective materials to recycle. This means that even after its long lifespan as a window, the aluminium can be melted down and reused without losing any of its inherent strength.

It takes 14,000kWh to provide a tonne of new aluminium, but it only takes approximately 700-1400kWh to recycle the same amount. This proves that opting for aluminium windows is a great choice for the planet as well as your home.


Thermal efficient

Aluminium windows are among the best insulated windows on the market. They offer superb heat retention that will save you money on your energy bills. 


Slim sightlines

The strength and sturdiness of aluminium means it doesn’t require bulky frames to provide support. Aluminium frames can be constructed with razor-slim sightlines to maximise the glass area and hence maximise the view. 


Minimal maintenance

Aluminium windows require very little maintenance to remain in great condition. As a strong and sturdy material that doesn’t rust, rot or bend, you’re unlikely to need to repair or refurbish the frame throughout its lifespan.

Aluminium frames are powder coated, meaning they won’t need to be repainted and the colour won’t fade.

A simple clean of the glass and frame every couple of months will help remove dirt and keep the window looking great.



Aluminium is one of the most cost-effective choices for windows. It is typically much cheaper than wooden frames such as timber, while outlasting cheaper frames such as uPVC. It’s important to remember that if you go for a cheaper frame, it will likely degrade much more quickly and end up costing you more in the long run.
