With the recent energy price rises and a second hike expected to take effect this autumn, it’s no wonder individuals across the UK are looking for ways to increase the energy efficiency of their homes and avoid incurring increased costs.

Windows and doors can be among the most common causes of poor temperature control within a home, especially if they’re not double glazed.

At Clement Windows, we take pride in our ability to create bespoke steel window solutions which satisfy our customers’ requirements.  Don’t just take our word for it – have a look through some of our reviews and hear what our customers have to say.


Longstanding customers

We have long standing relationships with our residential and commercial customers and partners.  We are proud to have received great feedback from a number of repeat customers who know they can expect high-quality products and great customer service from the team at Clement Windows.


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.”

Clement project wins a Sussex Heritage Trust Award

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.

Our most popular steel window and door ranges

March 10th, 2022

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 can also be suitable for new build projects, as it achieves up to a B energy rating.

Some examples of our EB24 window installations –

Commercial roundup – some of our favourite 2021 projects

February 4th, 2022

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.

Find out more about the details of this project here.
