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.

March 13th, 2023

When new Clement steel windows and doors were selected for this beautiful Grade II listed barn conversion located in the West Sussex countryside, we knew the project was perfect for inclusion in recent articles in Listed Heritage magazine and Conservation & Heritage Journal.

The barn has been sensitively restored by its owners with a particular focus on sustainability and energy efficiency.  New Clement SMW steel windows and W20 steel doors were chosen because they are similar in style to the original metal windows but provide better thermal efficiency to the originals and also let in more light.

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%).
