Aluminum is one of the most versatile materials available to mankind. It’s a key ingredient in the engineering of our time because it offers such a valuable combination of properties. Three times lighter than iron and almost as strong as steel this material can be manipulated into just about any shape or size it’s needed for, and it’s cost-effective! Aluminum can be found in countless times in our everyday life; inside our kitchen cupboards, our smartphones, the planes we fly in, our beer cans, and our homes. The uses of Aluminium are arguably endless. Previously, the go-to material for windows in commercial buildings, the popularity of Aluminium windows in homes has grown steadily for years. In fact, it’s set to overtake uPVC as the first choice in new home builds and replacement windows.

But won’t metal window frames rust?

It would be easy to assume that having metal window frames would result in some form of rust. Aluminum will not rust. Rust is a form of corrosion. It is the result of iron or steel being exposed to water or moisture. To put it simply aluminum does not contain iron or steel, therefore, rust is impossible. Aluminum can be susceptible to other, less aggressive types of corrosion, however, aluminum windows are now sealed with powder coating technology to protect window frames from their external environment. In fact, this polyester color coating is also a design feature coming in just about any colour that you can imagine.

Thermal Performance

In the past, aluminum windows have been associated with poor heating, especially in the industrial environments where they were primarily used. Known for letting the cold in, we would never consider this option for our homes. Aluminum windows have come a long way since then. These days, aluminum windows guarantee warmth wherever they are used due to the development of polyamide technology which reduces heat loss by providing a protective barrier within the window frame.

Aluminum vs Timber 

In terms of durability, you are going to have to retreat timber windows to stop them from rotting and decaying. The first treatment would be due 1-2 years after installation and then required every 6-8 years until the windows needed to be replaced altogether. If you are willing to keep up with this maintenance and regular upkeep then timber would work for your home and may last up to 60 years, however, if rots sets in they will have to be replaced entirely in as little as 10 years. In comparison, Aluminium framing is largely maintenance-free, requiring a regular clean and nothing else. Regardless of the weather aluminum is exposed to, it won’t rot, crack or warp like wood.

Aluminum vs uPVC

As previously mentioned, aluminum is fast becoming the go-to option for window installations, and there are several reasons why. Alumiums strength means that the window frames can be far slimmer than the uPVC. This allows sleeker design and allows more lighting into homes. At the same time, they provided the equivalent level of safety and security with reinforced frames and multi-point locks. While more expensive at the outset, Aluminium windows have a life expectancy of 45 years which is far superior than the 25-35 year life expectancy of uPVC windows.

Aluminum is arguably the most durable and substances on the planet, choosing this material for your windows will offer safety, style, and longevity.
