Why steel windows are the sustainable choice

May 23rd, 2019

We recently covered some of the common misconceptions people have about steel in one of our blogs. One area we discussed was the thermal efficiency of steel windows and we explained that we only use the best glass units, teamed with thermal barriers and weatherproofing, in order to maximise your window’s performance and keep energy bills down, ultimately helping you to exercise a more sustainable way of living. But you might not be aware how sustainable steel is as a raw material is too.

Here are some of the reasons why opting for steel windows, doors or screens in your home really is a sustainable decision.


Steel is endlessly recyclable

Did you know that there is no limit to how often steel can be recycled? Steel is one of the most recycled materials in the world due to the fact that it does not degrade in either quality or performance. According to, two out of every three tonnes of new steel are produced from old steel and the industry has long recycled its by-products too.

At Clement Windows, all of our steel windows are made from recycled steel, meaning you really are making a green choice when you choose our windows, doors or screens.

Steel is a malleable material

As well as being endlessly recyclable, the properties of steel lend themselves well to heat and there are no limits to the number of times heat can be applied. This demonstrates that steel is an incredibly malleable material that can be manipulated into all manner of elegant shapes and structures, whilst also maintaining its hardness and strength.

Steel will stand the test of time

The longevity of steel is what makes it one of the most cost effective options for windows in the long run, as it will usually last for generations. This means that you won’t need to worry about having to replace your steel windows every 15 years or so, but when the time does come to replace them you can be sure that you are selecting a premium long lasting product.

All Clement steel windows are hot dip galvanised in a range of Akzo Nobel colours with an average paint coating of 100 microns, well above the industry standard of 60 microns.

So, to summarise. Hot dip galvanised, hot rolled steel window and door frames have a similar life expectancy to the building they are fitted into – no other window or material can match that longevity!
