Aluminium Windows

Why Choose Aluminium?

Aluminium is becoming the top choice for windows and doors, as it offers multiple benefits. Compared to the classic uVPC and timber frames, it is much more durable and does not flex or warp when hit by changing temperatures.

It is also a corrosion-resistant metal, which adds an added layer of protection, making it an ideal choice for external doors. Furthermore, it will maintain its integrity for years to come.

With energy efficiency being of utmost importance, they have insulating properties that prevent heat transfer. They can be a crucial component in helping you to reduce your energy costs, making them a practical solution.

If you are seeking a sleek and modern-looking home, aluminium is the perfect material. Its slim lines help to maximise natural light, creating a sense of openness in your house. This makes them a great choice for a contemporary look.

Our range is also available in a selection of finishes, colours and sizes, providing a bespoke solution, tailored to your exact needs.
