We specialise in replicating existing heritage metal windows, helping you to maintain the original character of your property.

Whether your project is a Listed Building or a modern new build, a residential home or an office block, we have a steel window range to suit your requirements.

We offer our residential clients five different ranges of heritage-style steel windows – EB24, EB20, EB16, SMW and Brooking – and all of these are also available to our commercial clients, together with our W20, W40 and MW40 ranges.

Several of these window ranges are suitable for heritage refurbishment projects where metal windows are required.

Clement is also able to manufacture and install cold formed steel systems by Jansen which offer aesthetically pleasing slim profiles and improved energy efficiency.
