Clement Windows Group

Clement Windows Group Clement offers an innovative range of steel windows, doors, screens and conservation rooflights.

Clement manufactures an innovative range of steel windows, steel doors and steel screens for both private residences and commercial projects. We provide a complete service – from the provision of technical drawings through to manufacture, installation and after sales support - whether your project is a traditional restoration project, one involving Listed Buildings or Conservation Areas, or a new

build. Our previous work includes prestigious heritage projects across the UK and in the USA, including well known buildings such as Bonhams in London, Norwich City Hall and the Eldorado Building in Manhattan. We take pride in our reputation for premium products, excellent craftsmanship and industry expertise and we are delighted that so many of our customers return to us time and again because they know they cannot get a better window anywhere else. We specialise in manufacturing new steel windows which look similar to original or existing heritage metal windows. Our hot rolled steel windows and doors are produced from 98% recycled steel source material and meet the latest performance requirements for insulation, weatherproofing and security. We also manufacture cold formed, thermally broken steel profile systems by Jansen. All of our windows are crafted to your bespoke design in our ISO 9001 and ISO 14001 approved factory. With Clement Windows you can expect technologically advanced, yet low maintenance steel windows, which will last for many years. Clement also supplies a selection of conservation rooflights, available from stock in either a tile or a slate profile. If a standard size does not meet your requirements, bespoke options are also available.

From Arts & Crafts to Art Deco, steel windows played a defining role in some of Britain’s most iconic architecture. Sir Edwin Lutyens used them to bring rhythm, balance and light to his celebrated country houses.

Today, Clement are often asked to replace the fenestration in Arts & Crafts style homes with new, genuine steel windows and doors that are sympathetic to the original design. We explore some of these projects in our latest blog, ‘Steel Windows for Arts & Crafts Projects’.

Several members of the Clement team have recently travelled to Malta on holiday. Naturally, they all visited The Brewhouse in Valletta - not only to sample the fabulous beer on offer, but also to admire the new Clement steel windows installed there.

The venue comes highly recommended if you are planning a trip to this stunning island, often described as a “jewel in the Mediterranean”.

Clement products have been installed all over the world, and we have just delivered more bespoke steel doors for an exciting new project in New York City.

Clement have completed a fantastic project at Welford and Wickham CE (VA) Primary School - where all the windows were very different!

Working on a building with such historical character gave us the perfect opportunity to showcase the versatility of our EB16 range. From arches to unique angles, every steel window was carefully crafted to fit seamlessly and complement the charm and uniqueness of the building.

We’re thrilled with the final result, and so is the client.

✨NEW CASE STUDY!✨

The Horizon Youth Zone is a state-of-the-art youth charity in Grimsby, providing a safe and accessible space for young people in the local community.

Located in the heart of the town centre, the facility brings new life to the former West Haven Maltings and Migar House buildings.

West Haven Maltings, a beautiful Grade II listed building, originally featured traditional steel windows. Clement were delighted to be appointed to replace these with new steel windows from our W20 range.

The result carefully preserves the building’s historic character while significantly enhancing thermal and overall performance—ensuring the space is fit for modern use without compromising its heritage.

We wish the charity every success for the future and hope it becomes a much-loved hub for young people in the area.

🔥HOT OFF THE PRESS - Our April Newsletter Has Landed!

As you may know, one of our many specialties lies in crafting beautiful steel windows and doors for listed and historically significant buildings.

In this latest edition, we’re proud to showcase two recently completed projects - one Grade II Listed and the other Grade II* Listed. For both, we carefully manufactured new replacement steel windows designed to match the originals as closely as possible.

In the newsletter we also discuss our range of conservation rooflights, which were designed to complement traditional architecture.
