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.

Delighted to provide our steel windows and doors to Southern Design Windows for one of their latest projects - Market Hall.

A look back at one of our more unique projects 🤩

We were delighted to be trusted to supply and install Clement steel windows and doors as part of the redevelopment of Newton Abbot Market Hall.

The project is a great example of heritage architecture being carefully combined with modern design, retaining the character of the original building while creating a much more versatile space for the town.

The updated Market Hall now includes street food units, a bar, café, improved retail spaces and a flexible area for pop-up stalls, events and community use.

It was a fantastic project to be involved with, and we’re really pleased with how the steel windows and doors complement the original stonework and overall character of the building.

Clement recently installed our EB20 steel windows into this Arts & Crafts family home in Hampstead Garden Suburb.

We carefully recreated the geometric leaded lights, with diamond and hexagonal detailing.

The result is a perfect blend of period character and contemporary performance.

It was a sad day at Clement Windows yesterday as we said farewell to our colleague, Pier, who is retiring.

Some of the team gathered for a few drinks in the sunshine to celebrate his retirement and wish him well for the future.

Pier will be greatly missed around the office, but we all wish him the very best for a long, happy and well deserved retirement!

Enjoy every minute Pier! 🍀☀️🍀

We’re usually asked to paint our bespoke steel windows and doors in black, white or shades of grey - so we love it when something a little different comes along.

For this project, our task was to replace the original green windows and doors with new EB20 steel frames that would look as close as possible to the originals.

RAL 6028 Pine Green was chosen for the new frames, and it proved to be the perfect match. 💚

The new windows and doors not only look fantastic, but also provide:
• improved thermal efficiency
• increased security
• easier, lower-maintenance

Remember our EB20 steel windows and doors are made from 98% recycled steel, so these really are green through and through!

The case study is now live on our website and includes what our client had to say about the project.

For this luxury family home in one of North West London’s most carefully protected Conservation Areas, we replaced the original steel windows and doors with bespoke Clement EB20 steel windows and W40 steel doors.

Featuring curved windows, dual-colour finishes, genuine T bars and a combination of clear glazing, the result combines the character of traditional steel fenestration with modern thermal performance, security and longevity.

We’re delighted to share that the full case study is now live on our website - and it features a stellar testimonial from our client too!
