Reeded glass and steel partitions feature in recent Clement Windows projects

July 27th, 2023

We have been asked to manufacture our beautiful steel door screens with reeded glass for a couple of exciting recent projects.

Interior designer Cherie Lee has opted for reeded glass in some of her recent schemes, including her company’s showroom in Hertfordshire. Cherie Lee has long been a fan of our steel and glass screens, but chose to have this one painted white for a softer look. The inclusion of reeded glass softens the view into the storage area on the other side of the doors.

Clement’s yellow & red steel doors brighten up new basement space

March 22nd, 2023

If you follow us on social media, you will have seen how excited we have been about this recent colourful project.

When de Gournay Director Hannah Cecil-Harden was reconfiguring her London home to accommodate her growing family she approached Clement to provide the steel doors for the new basement space which comprises a playroom, utility room and bathroom.  The walls of the playroom were to be adorned with an idyllic hand-painted wallpaper scene of London, full of quirky characters and primary colours, and Hannah wondered if the new steel doors could be painted to match.

The result is a vibrant and fun space for the lucky children of the house.  The Clement steel doors made from our EB24 steel sections are painted in three colours in total – a traditional RAL 9004 Signal Black on the exterior, RAL 1016 Sulfer Yellow on the playroom side and RAL 3005 Wine Red on the utility and bathroom side.

The Sustainability of Steel

January 20th, 2023

In a world of seemingly limited resources, steel is a highly sustainable metal with the possibility for infinite recycling with no downgrade in quality.

Seen as vital to the development of modern economies due to increasing global demand and its environmental credentials, here we take a look at steel’s place in design and construction, particularly its applications to steel window and door manufacturing.


How steel is made

Steel is traditionally made using either the Basic Oxygen Furnace (BOF) or the Electric Arc Furnace (EAF) method; however, while the BOF route can only accommodate 35% recycled steel, the EAF method can accommodate 100% recycled steel.  In the UK, the infrastructure is not available to meet the demand for recycled content above 35% so steel is instead sourced from Europe.

Steel is one of the most recycled materials in construction, requiring recycled steel in the production process of all new steel materials.  The recycling process for steel is relatively uncomplicated.  It is processed by magnet and melted down, removing complicated separating procedures and the processing element generally produces very little waste.

Steel is inherently strong and can be recycled infinitely without losing this innate quality.  At the end of its life cycle, a steel product can be recycled and made into new products that are of an equivalent standard to the original material.

At Clement we care about quality and sustainability.  That is why all the hot rolled steel used in our windows and doors comes from Montenstahl in Switzerland and is made using the EAF method.  The company is committed to sourcing its raw material at prestigious European mills that comply with high levels of recycling and where profiles in the form of hot rolled steel billets are manufactured with a very high amount of recycled scrap metal (typically around 98%).

The benefits of double glazed steel windows

September 7th, 2022

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.

The benefits of double glazed windows go beyond money saving, improving the comfort of your home through temperature control noise-proofing. But what actually makes double glazing so effective?

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.

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.

2021 has undoubtedly been a testing year for many. Despite the challenges of this year, we have worked tirelessly to continue to deliver our range of high-quality, bespoke steel windows, doors and conservation rooflights.

Clement has had the pleasure of working with a number of new clients, delivering a unique range of steel-framed units across both residential and commercial clients. Here are a few of our favourite projects from 2021.

Ground-breaking modernist house updated with new Clement windows

The owner of this Grade II* listed property in Surrey was looking for windows and doors to complement the original ‘modernist’ aspects of the property. Built-in 1932 by well-renowned architects Connell, Ward and Lucas, this home is a perfect example of the Modernist Movement in architecture. Finished with our EB20 windows coated in matt Pastel Blue, and EB20 doors with multi-point locking, the rooms in this home benefit from the early morning and late afternoon sun.

Increasing Security with Steel

June 17th, 2021

What does ‘home’ mean to you? In most cases, at the forefront of your mind will be a space that provides comfort for you and your family.

At Clement Windows, we are able to deliver high quality, high security, steel windows and doors to fit your bespoke designs, offering support at every stage of the process.

Securing your home

Windows and doors are probably the most important factors in securing your home but are all too often neglected in favour of other automatic security systems.

Although the front door is the most common entryway to your home, windows are generally the most fragile and therefore the easiest points of entry for unwelcome visitors.

It is important to make sure that all possible entry points to your home are up to scratch when it comes to security.

What are today’s buyers looking for in new homes?

July 29th, 2020

Throughout the lockdown period, the majority of households have had to get used to spending a lot of time at home, causing many to reflect on the things they’d be looking for in their next property.

According to a Rightmove survey earlier in June 2020(1), 39% of buyers have reassessed their priorities as a result of the pandemic, with 63% wanting a larger garden or access to garden space and 43% looking for a bigger home in general. Furthermore, similar research conducted by Zoopla found that 22% of house hunters would prioritise a home office space (rising to 35% for those aged between 35-49) and 21% see lower household running costs as a ‘must-have’(2).

So, whether you’re looking to make the move to your next home or are considering taking on a home improvement project to get more from your current space, we’ve pulled together some inspiration to help get you started.

The right steel windows for your architectural style?

December 10th, 2019

The windows you choose can say a lot about your property – in terms of defining the character, style and heritage of the building itself, but also the positioning and layout of your interior spaces and how much natural light they receive.

Steel is a remarkably durable material that has been used to create strong and elegant windows for centuries, which means that it lends itself well to both the renovation of historic and Listed Buildings and the construction of new builds.

In this blog we take a closer look at some of the most prominent architectural eras to help you decide the right style of steel windows for your home.
