Why aluminium windows and doors?

Why aluminium windows and doors

Aluminum is often described as a ‘magical metal.’ It’s a metal that’s highly abundant on Earth, and it’s found mostly in the form of bauxite ore. But why is it such a good choice for doors, windows, and curtains?

Well, there’s a reason why the use of aluminium is increasing at an exponential rate of over 5% every year. It’s the chemical, physical and mechanical properties of modern-day alloys. Aluminium frames continue to grow in the glazing market and now dominate the commercial and residential sectors, competing with PVC-U.


Aluminium windows are cheaper than other window frames to save a lot of money. Timber frames are usually a lot more expensive than aluminium, plus they need more maintenance. You might be able to save some money by using plastic frames. On the other hand, uPVC frames tend to degrade over time, so they’re more expensive in the long run.

Very strong

Windows, doors, and curtain walls are made with aluminum alloys. There’s a reason for that. Aluminum doesn’t have a strong tensile strength. On the other hand, if it is alloyed with other elements such as silicon, manganese, copper, and magnesium, it becomes powerful. An alloy of aluminum can be stronger than 690 MPa. The tensile strength of pure aluminium is around 90 MPa. As we have already discovered, aluminum, one of the lightest engineering metals, has a higher strength-to-weight ratio than steel when used in an alloy.

The strength of aluminum increases as the temperature drops, unlike steel, whereas steel turns brittle at low temperatures (below 0oC). Because of this, aluminum windows, doors, and curtain walling in the UK can withstand even the worst winter temps. It was -27.2°C in Scotland, which had the lowest temperature in the UK.
