The best on the market’ from Tom Robbins – Google reviews – 5 stars

“Clement supplied the steel windows with leaded lights set into oak subframes for an Arts and Craft house we worked on in Weetwood, Leeds.  We built an orangery there, as well as the garage and kitchen conversion.  Clement replaced the windows throughout the existing house as well as supplied the new fanlights for the orangery.

We also specify Clement’s conservation rooflights whenever we can.  We are very much of the opinion that they are the best on the market.”

Did you know that all Clement steel windows and doors are hot-dip galvanised to EN ISO BS 1461 and available in a choice of highly durable Akzo Nobel powder paint colours?

Clement provides an average paint coating of in excess of 100 microns on flat surfaces – the industry standard calls for 60/70 microns – giving a superb finish.

We offer an extensive number of RAL colours within our standard price range.  The classic steel window frame colours shown here are recommended because in our experience these not only look the best but retain their appeal over time.

We also offer a dual colour finish where you can have the window frame painted one colour internally and another colour externally and it is possible to opt for specialist colours such as metallics for both paint and silicone.

Just speak to one of our sales advisors for further information.

A West Sussex residential project for which we recently manufactured steel windows, steel doors and steel screens has been announced as the winner of an award at the 2021 Sussex Heritage Trust Awards.

Thirty awards were presented overall and the project which is near Arundel won one of the Small Scale Residential Awards.

Clement EB24 metal windows and doors were installed at the Grade II listed 16th-century building.  The large expanses of glass allowed lots of natural light in and improved the thermal performance of the building.

The Sussex Heritage Trust is a charity established in 1977 to preserve, improve and encourage the appreciation of the architectural and natural landscape of Sussex.

At Clement, we pride ourselves on the manufacture of high-quality steel windows and steel doors, made to your bespoke requirements in our very own ISO 9001 approved factory.

While all of our ranges are developed to meet the ever-changing demands of clients and the wider industry, there are a few ranges that are particularly popular, boasting the elegant good looks, incredible versatility and modern performance requirements you can expect from Clement.


Most popular for replacement steel windows: EB24

EB24 is our most popular and versatile steel window product for both commercial and residential work.  Benefitting from exceptionally slim frames, our high specification EB24 steel window range is superior to your original metal windows.  It offers better thermal performance, security (PAS 24 is an option) and it is also very easy to maintain.  Clement specialise in manufacturing new steel windows and doors to match your originals, but with a far improved specification.

Although the EB24 range is our most sought after product for replacement work it is also suitable for new build projects, as it achieves up to a B energy rating.

Over the course of 2021, we have had the pleasure of working on a number of commercial projects which now feature our range of high quality, bespoke steel windows, steel-framed doors and screens and conservation rooflights.

We have taken a look back at some of our favourite projects from the year and picked out a few highlights.


An upgrade to a Grade II listed Town Hall

Waltham Forest Town Hall

Possibly one of the most distinct examples of ‘Stripped Classicism’ architecture in the UK is Waltham Forest Town Hall. The office building was designed by architect Philip Hepworth and constructed between 1938 and 1942. In 2019, the council approved an extensive programme of renovations, including the replacement of all the original steel windows. Working with the client to select the right high-quality product for the project, a suite of Clement W20 white metal windows with dark bronze fittings were installed seamlessly, despite being in the midst of a pandemic.
